DVD 2010 Show News From Allison Transmission And Tachoblog

Tachoblog — Wed, 23 Jun 2010 10:50:38 +0000

Allison Transmission invites DVD 2010 visitors to visit stand OR24 on June 23rd and 24th 2010 to learn how its prognostics software and driveline calibration features can help prolong vehicle life, while delivering reliable performance, regardless of task or theatre.

Allison has a long heritage in the supply of rugged transmissions for combat, tactical and support missions in both wheeled and tracked vehicles for the armed services. Products favoured by the UK military range from the Allison 2000 Series for light armoured tactical vehicles to the 4000 Series for heavy equipment transporters. On display at DVD 2010 will be the Allison 2500SP as specified on Jackal (pictured above), Coyote, RG-31 Nyala, Cougar vehicles along with. the 3000SP supplied for the Mastiff, Wolfhound and Ridgeback.

“Allison understands that NATO forces are looking for standardised production-ready components which can be used in military applications,” Riccardo Sardelli, Allison Transmission’s UK area manager told Tachoblog.

“Allison therefore offers the SP Series of commercial duty fully automatic transmissions which have proven reliability, durability and the required flexibility to fit military requirements without the need for extensive modifications. We offer effective product support through a worldwide service network of over 1,550 distributor and dealer locations. Our Allison team works closely with original equipment manufacturers to deliver solutions for the unique challenges faced by today’s armed forces.”

Calibrated to the particular requirements of the vehicle, Allison Prognostics monitor operating parameters to determine and alert when a specific maintenance function is required. Fluid, filters and transmission health status can be monitored simply by consulting the shift selector display.

Eliminating the guesswork and hassle of scheduling routine vehicle maintenance as well as unnecessary oil and filters changes, Allison Prognostics save time and money while providing maximum protection for the transmission.

Through Allison Transmission’s experience working with defense customers, its experts have developed a wide library of ‘mission profiles’ – the best configurations by application – and a clear understanding of the factors which affect both vehicle performance and fuel consumption.

Allison fully automatic transmissions are relied upon by the armed services for their extended torque range, higher GVW capacity and advanced electronic controls to get the most performance out of the engine, by delivering more power to the wheels. Allison products are fully automatic powershifting transmissions, which provide faster acceleration, superior traction and greater manoeuvrability in all conditions. Advanced electronic controls automatically command the right shift at the right time to maximise vehicle performance yet maintain engine speed within its optimal range.

Allison automatics are arguably most impressive when it comes to startability on hills, grades or soft ground. Allison’s torque converter ensures engine torque multiplication at vehicle launch and transmits it gradually to the wheels, which enables smooth and steady starts as well as unrivalled rocking ability. Also driveline wear and tear is reduced since the transmission’s torque converter – with torsional damper – absorbs shock loads from both directions, ensuring that the driveshaft, differential, axles are protected.

In hilly terrain, the absence of rollback is another safety factor and the capability of operating at low speeds smoothly, without clutching and shifting gears, is much safer and less fatiguing for the driver and ground personnel. Because Allison transmissions are inherently easy to operate, drivers can concentrate on their mission, remain alert, and experience measurably lower stress.

The Manitowoc Grove GMK6300L All Terrain Crane On Tachoblog

Tachoblog — Tue, 20 Apr 2010 11:18:31 +0000

A crane! On Tachoblog! Yes, it’s big enough, heavy enough and, most importantly, uses Tachoblog’s favourite fully automatic gearboxes, the Allison Transmission 4500 SP.

Manitowoc, a leading manufacturer of lifting equipment for the construction market has selected the proven technology of fully automatic transmission specialist Allison Transmission for its new Grove GMK6300L. Set to be launched at the 2010 Bauma, the six-axle all-terrain crane with an extended boom offers more power and, thanks to the 4500 SP fully automatic transmission, outstanding manoeuvrability and driver comfort. And that’s one of the beasts above.

Click below for more…

The GMK6300L is capable of lifting 300 tons and features a main boom that can extend 80 metres. For further operating distance a 37 metre boom extension is also available. The lifting capacity of 12 tons at 80m simplifies tasks such as tower crane erection, placing air conditioning units and elevator equipment on high rise buildings or chimney work.

The crane is powered by a Mercedes OM 502 LA engine seamlessly matched to the six-speed Allison fully automatic transmission 4500 SP. Power for the crane boom comes from a separate Mercedes OM 926 LA engine.

“The GMK 6300L is the only one in its class which has a fully automatic transmission offering the best driveability on site,” Michael W. Preikschas, Grove’s senior regional product manager for all-terrain cranes in EMEA told Tachoblog. “The Allison 4500 SP is a strong, reliable and cost effective drivetrain solution. Its capabilities are proven even in the most arduous conditions and the electronic controls allow it to adapt to its surroundings and provide self-diagnostics for easier maintenance. An integral retarder offers enhanced braking on hills and greater safety for the operator when moving a heavy vehicle.”
Combined with Grove’s Megatrak suspension system, the Allison transmission offers excellent manoeuvrability even in the most narrow lift conditions that face operators on construction sites. Now firmly established in the crane market for many years, Allison transmissions are equally valued by crane operators and drivers thanks also to their high reliability and ease of use.

The latest crane continues an extensive partnership between Grove and Allison; Grove offers Allison fully automatic transmissions across its range including in the GMK5170, GMK5220, GMK6220L, GMK6300 and GMK7450 models.

Bauma Debut For New Allison Products And Features

Tachoblog — Tue, 30 Mar 2010 10:26:33 +0000

So why’s your Renault Kerax perched on a cliff then Tachoblog? Well, this is to illustrate that Allison Transmission will present their new 6620 fully automatic transmission and new transmission features at the Bauma 2010 exhibition.

Visitors Allison’s Stand (hall A4, booth 414)at Bauma 2010 (19 – 25 April, New Munich Trade Fair Center) will be the first to see Allison Transmission’s latest Off-Highway Series model – the 6620 – as well as upgrades to the versatile 4000 Series transmission that is so popular to the construction market.

Click below for more…

The new Allison 6620 transmission builds on the proven rock solid performance, reliability and durability of the existing 6610 model (which it replaces) with improvements to the lock-up clutch, turbine shaft, turbine hub and flywheel, all designed to improve maintenance costs and reduce downtime.

The 4000 Series has been upgraded with an optional provision for a ground-driven pump, to ease the installation of the emergency steering system, a requirement for most European 8×4 tippers. Allison now also offers a 2nd ‘deep reverse’ gear in addition to the standard reverse gear – exclusively available on 4700 and 4800 Series – seven speed models. The 4000 Series six and seven speed transmission range is available with close and wide gear ratios and is popular in construction applications and articulated dump trucks as well as oilfield and crane applications.

Also on show at Bauma is a new Allison-equipped Grove GMK6300L crane (Manitowoc booth, open-air ground F10, booth 1002/6) and a new Mercedes-Benz Zetros multipurpose vehicle with an Allison 3000 Series transmission (Mercedes-Benz booth, Hall B4, booth 102/204).

Allison Transmission is a global leader in transmission technology used in mining and construction trucks, cranes, and oilfield equipment. Allison-equipped vehicles can be found operating around the world in mines, gravel pits, stone quarries and other challenging operating environments. Even under the toughest conditions, Allison transmissions are reliable, durable and efficient: whether in a BELAZ dump truck in Siberia, in a Volvo heavy haulage truck in Sweden or in Tucker snowcats in Antarctica.

To continually offer ground-breaking and reliable propulsion solutions for various application areas of the construction industry, Allison optimises its off-highway and off-road series transmissions, supporting customers with tailored solutions backed by a global service network of over 1,500 distributor and dealer locations.

In addition to the Allison 4000 and 6000 Series transmissions that will be featured at Bauma, the full range of Allison transmissions, from the 1000 Series to the 9000 Series is designed to support a multitude of rigorous tasks at mines and on construction-sites. The smallest Allison 1000 Series is used in heavy duty pick-up trucks, while the 3000 Series equips medium-sized support vehicles and cranes with engine ratings up to 425 HP or 1695 Nm. The 5000, 8000 and 9000 Series are the largest transmissions offered by Allison. Like the 6000, they are suitable for stationary and mobile off-highway applications. The 9000 Series can handle engines with up to 2,250HP and a torque of 8270 Nm.

With increasing pressure on the mining and construction industry to reduce down-time, increase vehicle efficiency and improve productivity, Allison’s growing presence in the construction sector is supporting these objectives. “Vehicles with Allison transmissions are more productive, require less maintenance and repair and can achieve higher efficiency and optimised operation,” Manlio Alvaro, Allison Transmission marketing manager EMEA told Tachoblog.

“Allison continues to innovate and improve our products in order to retain the rock solid reputation we have earned over the past 60 years supplying transmissions to this market segment. That is the reason why more and more operators on construction sites around the world appreciate Allison transmissions.”

Allison And The Venomous Snake Truck

Tachoblog — Mon, 15 Feb 2010 14:15:20 +0000

No, this isn’t a lucky escape travel story, but news that the introduction of a new engine and the latest fully automatic transmission technology has seen a military vehicle produced by Engesa that was a success in the 80s and 90s back in front line action.

Considered by many to be out of action – as the last units were, for many years, parked in the battalion storage of the Brazilian Army – the armoured Engesa EE-11 Urutu may yet be ready for service again.

Click below for more…

Destined for troop transportation, the EE-11 despite weighing 13 tons, is a highly capable amphibious vehicle. Together with its carrying capacity, these features made the Urutu very popular among many national armies in South America. With a new powertrain, it is set to strike again.

Its name was taken from the venomous Urutu snake, from the family of Veperidae, the same as the rattlesnake, the bushmaster and Jararaca – the three feared reptiles of the South American forests. The Urutu’s attributes and importance to the Brazilian Army led the local force to decide to reactivate 226 units and more than 600 armoured Cascavel (or rattlesnake) vehicles. All of those were mothballed and in storage. With a very old-fashioned powertrain, and a mix of manual and automatic gearboxes, Urutu and Cascavel had a sizeable technological disadvantage during operations. The Brazilian Army believed that by updating the powertrain of their armoured vehicles, they could keep them running for the next 15 years. That claim was validated after a rigorous evaluation made with a prototype produced by those involved in the project.

For the first prototype the existing Mercedes-Benz OM 352 engine was replaced by a militarized OM 366 LA, increasing the power output from 158hp to 230hp. Coupled to the Engesa transfer box, the original Mercedes G3-36 gearbox was changed for an up to date Allison 3000SP automatic transmission, with electronic controls. The initial tests on light terrain saw the prototype reach a top speed of 110km/h. Over heavier off-road situations, the vehicle could travel at 80km/h. Crucially, the range was increased from 750km to 950km.

Engemotors, a company of the Brasília Motors group is undertaking the upgrade. According to Glauco Bueno da Silva, general manager for Engemotors, one of the reasons for using Allison’s automatic gearboxes on all the Urutu and Cascavel units is the improved drivability. Glauco told Tachoblog, “In a combat vehicle during battle, it is difficult for the driver to focus on the gear change coordination, clutch usage, choosing the best gear for each situation and so on. With an automatic transmission the driver is free from such distractions and so they can concentrate on the mission. The Allison 3000SP gearbox we now use is more resistant and delivered very interesting results during the tests. The performance is superior to old versions equipped with manual/automatic transmissions as that older transmission generation, when used in the Urutu, had no electronic management and lacked many updates which help vehicles to have better serviceability”.

Allison Aids Barcelona’s Sustainable Future

Tachoblog — Fri, 05 Feb 2010 10:17:36 +0000

Tachoblog’s favourite automatic gearbox manufacturer Allison Transmission is helping the city of Barcelona with its firm commitment to a sustainable future.

The city has placed Spain’s largest ever order for CNG trucks and all of the 300 natural gas vehicles, which will work for the environmental services department carrying out duties such as refuse collection and street cleaning, are fitted with Allison fully automatic transmissions. The public sector in Spain is increasingly opting for CNG vehicles due to their lower carbon dioxide and nitrous oxide emissions.

Click below for more…

The new CNG vehicles form part of a 350-strong truck order to be managed by environmental service providers Cespa, CLD, FCC and Urbaser. Each company chose Allison to reduce operating costs, improve fuel consumption and optimise service to the citizens of Barcelona, and not just for the CNG-fuelled vehicles. Allison equips almost 85 percent of the order’s total heavy truck requirement, including diesel vehicles.

More than 50 different vehicle configurations have been developed for this large fleet, including various bodywork applications and facilities for rear, left or right side loading and vertical loading by automatic crane. The vehicles are extremely diverse in both size and capacity. Ranging from three to 32 tonnes, the fleet includes street cleaning trucks, large and small refuse trucks and service vehicles which collect loads from small refuse trucks at isolated points of the city in order to reduce trips to landfill.

The common denominator in this dazzling array of vehicles and equipment is the Allison automatic transmission. The 2500, 3000R and 3200R Series transmissions were chosen for their reliability, cost efficiency and driving convenience. Each Allison comes with a torque converter as standard for powertrain protection and superior performance.

This is an essential feature in tough applications, such as waste collection, with constant stops and starts, very often with heavily laden vehicles, and it can deliver high productivity, more efficient fuel consumption and significant cost reductions.

The incorporation of fourth generation electronic controls in each Allison transmission results in smooth and faster gear changes, greater fuel efficiency and enhanced powertrain reliability. Allison transmissions have hydraulic retarders, which afford greater driver control of the vehicle. This improves safety and minimises wear on brakes particularly in vehicles equipped with a CNG engine.

There are also clear maintenance advantages to owning and running an Allison transmission which translate into shorter downtime and greater productivity. Because the automatic transmission does not have a starting clutch, it eliminates repair work and makes life easier for fleet maintenance managers. Most of the companies involved in the Barcelona contract are currently preparing their preventive maintenance plans in cooperation with Allison. Maintenance costs will be minimised through the use of the synthetic oil, TranSynd (TES-295), which increases intervals between oil changes six-fold.

Allison automatic transmissions make driving easier by facilitating manoeuvrability and eliminating repetitive clutch depressions and gear-change movements. This reduces stress and fatigue, allowing drivers to focus entirely on waste collection and traffic conditions and preventing typical muscular ailments.

Finally, the city benefits from the use of these automatic transmissions. The Allison’s quiet helical gears, along with the fact that transmission and engine are calibrated to operate within optimal RPM parameters, means noise normally associated with manual transmission trucks, is significantly reduced.

Tachoblog Influences Volvo – And That’s Official!

Tachoblog — Thu, 10 Dec 2009 13:04:31 +0000

It’s good to learn that Volvo Trucks listen to Tachoblog. They must have read that we and our friends over at TNN really rate the Allison Transmission fully automatic gearboxes – see Swedish Truck Extravaganza on Tachoblog with a Volvo FH16-660 and FE-230, Scania P380 and R480.

What you can see above is Volvo’s new UK and Ireland market specific low-entry version of their FE middleweight rigid.

Designated the FE Low Entry Cab (LEC), the new truck is aimed at the waste collection and recycling sector – in particular, the carriage of domestic refuse delivered direct to a bulk transfer or recycling station.

Click below for more and for why we know Volvo listens to Tachoblog…

In addition to municipal applications, the FE LEC is also designed to meet the need for ease of access of crews of specialist fire, airport and highways vehicles – particularly those working ‘stop-start’ duty cycles such as cone trucks in roadworks.

The Volvo FE LEC is configured around a 26 tonne GVW 6×2 rear-steer, tag-axle rigid chassis. Chassis layout is conventional and is available with the standard cab. Ninety five per cent of components are from the standard FE chassis – including key components such as mirrors, windscreen and cab panels.

The radiator, intercooler and steering box are also from the standard FE. Should the worst happen, cab and chassis parts are available throughout the Volvo Dealer Network.

The FE LEC is designed to cater for four crew (three crew plus driver) in comfort while providing easy entry and exit. The driver’s side of the cab features single step entry and the flat floor of the cab allows excellent cross cab access unimpeded by obstructions. This means the driver can also exit on the nearside – an important Health and Safety consideration.

The FE LEC cab is mounted 600mm further forward and 200mm lower than the standard FE. Crew entry and exit on the near-side is via a wide, low access step at a height of 550mm. Front air suspension gives the option of a kneeling function, when the doors are opened, for even lower step entry of only 440mm. Both cab doors feature wide apertures and open to a full 90º. The air suspension for both front and rear of the truck can be operated from a tethered handset controller located by the driver’s seat.

Seats are covered in easy to clean vinyl and the crew sit at the same level for excellent forward vision through the deep windscreen. The nearside crew seat is set back to aid driver visibility and there are windows in the lower passenger door and passenger cab side panel. Three point diagonal safety belts are fitted to all four seats.

With an overall width over the doors of only 2,300mm, easy to replace plastic mudwings, and a three piece bumper with steel corners, the FE LEC is designed to take the knocks and scrapes of urban life.

Cab equipment includes manually operated air conditioning, power windows, heated mirrors and additional storage for wet gear behind the driver’s seat.

Now that’s all very nice Tachoblog we can hear you thinking, but why are you crowing that you’ve influenced Volvo? Well, coupled to the FE LEC’s Volvo D7 Euro 5 engine with Selective Catalytic Reduction (SCR) (Power output 300hp at 2100 to 2300 rpm and peak torque of 1160Nm between 1200 and 1800rpm) is the Allison AL306 6-speed automatic with hydraulic torque converter and push button mode selection. See, they do read Tachoblog!

The AL306 features a live drive PTO. Rear axle ratio is 6.17:1 and the FE LEC can keep pace with city traffic at 26 tonnes GVW and also cope with the stop start demands of waste collection. Disc brakes feature the latest generation electronically controlled EBS.

The FE LEC offers operators a competitive unladen weight of 7,500kg +/- 1.5% (includes 215 litres of fuel, 70 litres of Adblue and no driver). In terms of axle capacity, the FE LEC offers 1,000kg of loading tolerance at 26 tonnes with an 8 tonne front axle and a 19 tonne rear bogie. The rear bogie is air suspended and chassis ride height is 1,000mm. The front axle is also available with air suspension (with the option of a kneeling function). 315/80R22.5 tyres aid axle capacity and provide increased ground clearance.

Feuer! Feuer! – That’s Fire! Fire! To You And Me Says Tachoblog

Tachoblog — Fri, 04 Dec 2009 12:28:08 +0000

Following on from our reasonably recent post ‘огонь! огонь! – That’s ‘Fire! Fire!’ To You And Me Says Tachoblog‘, we can tell you that Germany’s Munich fire brigade have ordered 58 new Mercedes-Benz Atego fire engines with fully automatic Allison transmissions.

Every second can count in the daily routine of a fire brigade, and emergency vehicles need to accelerate and brake fast to get quickly and safely through congested city traffic. The Munich fire brigade specified vehicles with a fully automatic transmission and integrated retarder having undertaken extensive tests to compare the performance of a fire truck with an automated manual transmission (AMT) and one with a fully automatic transmission.

Click below for more…

The conclusion was that the behaviour of the AMT during shifting and acceleration was unfavourable, while Allison’s torque converter provided continuous powershifting to the wheels without interruption of traction to enable smooth startability and fast acceleration. Keeping vehicles in close group formation is easier with fully automatic transmissions and its integrated retarder provides additional vehicle braking while extending service brake life.

The Allison-equipped Mercedes-Benz Atego 1429Fs feature bodywork by Iveco-Magirus fire protection engineering creating a package that not only meets all the necessary challenging demands but is also the most economically advantageous.

“We are exceptionally glad that the Munich fire brigade will benefit from the numerous advantages of owning an Allison in so many new vehicles,” Gerhard Voigt, OEM account manager at Allison Transmission in Germany told Tachoblog. “The outstanding reliability and durability of Allison transmissions result in less downtime, only minor maintenance requirements and thus reduced maintenance and repair costs.”

The first two vehicles have recently gone into service. The remaining 56 Ategos will be delivered to the Munich fire brigade between now and mid-2011 in four deliveries where they replace old fire engines. Thirty-two trucks are destined for the municipal fire brigade and 26 to the auxiliary fire brigade.

Munich’s fire brigade has more than 420 emergency vehicles, trailer, swap bodies and settling tanks. Approximately 1.650 people work at the ten fire stations and nine emergency doctor stations. In 2008 the vehicles responded to 61,430 calls for assistance of which 4,070 were fire fighting runs and 17,811 were for rescue duties.

You Can Keep Your PS3 Or Xbox Says Tachoblog – We Want One Of These For Christmas

Tachoblog — Fri, 04 Dec 2009 11:23:45 +0000

If you, like Tachoblog, like your racing games then this is the perfect Christmas present for you.

What you can see here is the Hexatech professional racing simulator made by Cruden. This is not a video game linked up to a steering wheel, race seat and pedals. Although easy to operate, this is the exact same equipment used by the top racing drivers and engineers to improve their race craft and evaluate new tracks and car settings. And you could have one in your living room!

Click below for more…

The Hexatech promises years of highly challenging entertainment both in terms of durability – it is built to endure hundreds of thousands of ‘driving’ kilometres per year in almost constant use and lasts 10 to 15 years without major overhaul – and in ensuring drivers never get tired of the quest to improve.

Speaking to Tachoblog, Frank Kalff, Cruden’s commercial director explained, “Driving a real Formula One car is not easy and getting fast and consistent laps in the simulator isn’t either.

“The simulator takes minutes to learn and enjoy but a lifetime to master, unlike most driving games which are conquered and then discarded before too long. The immense challenge of honing the same level of driving skill as a top racing driver is unbelievably addictive and satisfying.”

Creating a bespoke simulator – or even multiple linked-up systems – will introduce an unrivalled centre-piece within the home. The Hexatech is now available as a three-seater (3CTR), where passengers sit either side of the driver to experience the ride together.

Cruden can supply open or closed cockpits, fit bodywork or use actual vehicles, and apply the livery of a race or road vehicle according to customer preference. Owners can choose between three ‘wrap around’ 42 inch screens or (stereo) projectors to view their virtual world of state-of-the-art graphics.

Friends and family can watch the race projected onto nearby screens or walls. There is a wide variety of software packages and competition settings to chose from, allowing customers to host fast lap shoot-outs, 24-hour endurance races and full championships, as well as to select race tracks and cars; for example from Formula One, rally, NASCAR and sports car racing.

What about a Scania or Peterbilt racetruck option wonders Tachoblog..?

Ownership is made easy with full installation, training, access to upgrades and on-call support provided as part of the purchase. The electro-mechanical system typically requires only five KWh of electricity, making the Hexatech economical to run. The simulator has a footprint of 2.3 m x 3 m, requires a floor loading of 1,000 kg/m2 and a minimum ceiling height of 3 metres. Cruden also makes static and 3DOF simulators to customer order.

If you want one of these then you’d better head to www.cruden.com.

An Extreme Test Of Truck And Transmission

Tachoblog — Thu, 03 Dec 2009 12:13:47 +0000

Want to prove your product is any good? Well why not try a three week, 2,000km trip through Siberia? That’s exactly what Allison Transmission and Intekra Group – the official distributor of DONGFENG heavy-duty trucks in Russia – are doing with a 20-tonne DONGFENG DFL3251AXA (6X6) dump truck.

The trip, which kicked off on 30th November to cover the Tyumen Region and Khanty-Mansiysk Autonomous District of Russia, is designed to highlight to construction and oil and gas industry experts that a DONGFENG truck equipped with an Allison transmission can deliver maximum productivity, use fuel more efficiently and ensure ease of operation with superior safety and reliability.

Click below for more…

This most robust of trucks has a 375 HP DF Cummins ISLe engine which, for the first time as a one-off special application, is equipped with an Allison six-speed 4430 fully automatic transmission. Chinese DONGFENG trucks are well known to Russian transport workers and management at Intekra believe they could prove as popular to more vocations such as oil and gas, hence the ambitious test to showcase the DONGFENG/Allison combination at presentations in 13 cities along the route.

“Fitting the Allison transmission has allowed us to discover new capabilities of the DONGFENG vehicle and we believe this is one of the best heavy-duty trucks in the market” Saulevich Oleg Ivanovich, the First Deputy General Director of the Intekra Group told Tachoblog.

“For Intekra, the collaboration with Allison is a step toward expanding the product range as well as the circle of prospective clients, for whom we believe an Allison-equipped truck is needed.”

Given the current global economic downturn, the issue of production optimisation and technological effectiveness is particularly relevant to the oil and gas industry. Equipment that works under severe Siberian conditions – temperatures of about -25 to -35° C with ice, snow, frozen slush and greasy roads – must meet the highest standards of reliability and productivity. The Allison transmission is a durable, trustworthy transmission that allows heavy trucks to move either at very low or at high speeds, to travel on flat and steep ground, over stone trails or through muddy terrain.

Going Backwards Twice With Allison

Tachoblog — Thu, 26 Nov 2009 10:41:30 +0000

Tachoblog’s favourite automatic gearbox is gaining a second reverse gear. This is what it looks like…

As part of an ongoing product optimisation initiative, Allison Transmission is introducing a 2nd Reverse gear on all Allison 4700 and 4800 models for the 2010 model year.

This new feature offers a second ‘deep reverse’ in addition to the standard reverse to provide greater control and engine braking during operation on steep grades. 2nd Reverse will also enable increased manoeuvrability when operating in confined spaces, allowing quicker operation cycles and thereby boosting productivity performance.

Click below for more…

“Customers in construction and mining in particular, will appreciate the provision of a deeper reverse gear,” Larry Love, Allison Executive Director of International Marketing told Tachoblog. “The shorter ratios of 2nd Reverse will make up and downhill reversing much safer and easier in heavy duty applications, giving drivers additional confidence. This is another reason to specify an Allison fully automatic transmission, complementing features such as our adaptive Electronic Control Systems and integral retarder that aim to improve comfort and productivity for drivers and operators.”

When a vehicle is in 2nd Reverse, it will have a slow creep capability with high engine speeds. With a mechanical ratio of 17.12, it will have an effective torque converter multiplied ratio up to 32.5:1. The new 2nd Reverse feature provides overall better performance and enhanced applicability for a variety of applications. It will be available mid-year 2010.
