Allison Transmission has announced the launch of the TerraTran, its latest innovation in propulsion solutions purpose-built for the global construction and mining markets.

A variant of Allison’s proven 4000 Series transmission, the TerraTran is purpose built for off-highway applications such as mobile crane, articulated dump truck and wide-body mining dump trucks, with enough application flexibility to enable Allison to target multiple additional on-highway opportunities. TerraTran was developed based on customer feedback, which indicated a need for the proven reliability and durability of Allison’s 4000 Series transmission, but with increased horsepower, torque and GVW capability, while also adding fast reverse capability.

TerraTran has maximum power capability of up to 800 horsepower, and torque capability up to 3,025 lbs./ft., 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 optimised vocational efficiency. Field tests conducted over approximately two years have demonstrated that TerraTran delivers enhanced drivability, gradeability and manoeuvrability under demanding operating conditions.

Allison is also pleased to announce that in partnership with Xuzhou Construction Machinery Group (XCMG) headquartered in Xuzhou, China, the TerraTran will be launched first in XCMG’s all-terrain crane application.

“Collaborating with XCMG on their all-terrain crane application is a successful example of Allison working closely with our OEM partners to develop innovative solutions that deliver unparalleled performance and productivity to our end-user customers, all in an effort to Improve the Way the World Works,” said Kartik Ramanan, Executive Director, Global Off-Highway Sales, Customer Support and Service Engineering at Allison Transmission.
