Bell evaluates new Allison TerraTran transmission
Allison Transmission, a designer and manufacturer of conventional and electrified vehicle propulsion solutions and the largest global manufacturer of medium- and heavy-duty fully automatic transmissions for commercial and defense vehicles, has signed a partnership with Bell Equipment Group Services (Bell) to integrate and evaluate the Allison TerraTran in the next generation of Bell’s articulated dump trucks.
A variant of Allison’s proven 4000 Series on-highway transmission, the TerraTran is purpose built for off-highway applications such as articulated dump trucks, mobile crane, and wide-body mining dump trucks. TerraTran was developed based on voice of customer input, which indicated a need for the proven reliability and durability of Allison’s 4000 Series transmission, but with the increased horsepower, torque and gross vehicle weight (GVW) capability needed for off-highway applications, while also adding fast reverse capability.
Allison’s TerraTran has maximum power capability of up to 800hp and torque capability up to 3,200Nm, dependent upon the application in which it is deployed. TerraTran also features seven forward and two reverse speeds. With the additional fast reverse, TerraTran is said to deliver improved productivity and optimised efficiency.
