BELL to Integrate and Evaluate Allison’s Newest Off-Highway Transmission for Upgraded Articulated Dump Truck


Allison Transmission, a leading 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 defence vehicles, is pleased to announce 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.

“BELL and Allison have a long-standing partnership based on shared values and a proven history of innovation and reliability,” said Tristan du Pisanie, General Manager of Product Development and OEM Marketing at BELL. “We look forward to evaluating TerraTran in our vehicles, as part of our effort to deliver enhanced drivability, gradeability and maneuverability for BELL customers, while maintaining the durability that Allison transmissions are known for.”


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 has established a successful relationship with BELL over the past 25 years and we look forward to continuing our longstanding partnership through the integration of our latest propulsion solution for BELL’s evaluation,” said Kartik Ramanan, Executive Director, Global Off-Highway Sales, Customer Support and Service Engineering at Allison Transmission. “Purpose built for global construction and mining markets, TerraTran leverages Allison’s more than 65 years of experience moving earth, minerals and precious metals around the world where Allison Automatics have proven themselves in some of the most challenging conditions imaginable.” Allison’s TerraTran has maximum power capability of up to 800 horsepower, 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
