Allison Transmission showcases Off-Highway 6620 Series model at Bauma 2010
(06/04/2010)

Allison Transmission will showcase its latest Off-Highway Series model – the 6620 – as well as upgrades to the 4000 Series transmission at Bauma 2010. The new Allison 6620 transmission builds on the proven 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 8x4 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-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.

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,” says Manlio Alvaro, Allison Transmission marketing manager EMEA. “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.”
