Allison Transmission, a designer and manufacturer of conventional and electrified vehicle propulsion solutions and a global manufacturer of medium- and heavy-duty fully automatic transmissions for commercial and defense vehicles, has announced 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 4000 Series on-highway transmission, the TerraTran is 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 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 800 hp, and torque capability up to 3200 newton meters, dependent upon the application in which it is deployed. TerraTran also features seven forward and two reverse speeds. With the additional fast reverse, TerraTran delivers improved productivity and optimized vocational efficiency.
