Allison Transmission adds to off-highway propulsion solutions with TerraTran

Allison Transmission has launched 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 cranes, articulated dump trucks 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 increased horsepower, torque and gross vehicle weight capability, while also adding fast reverse capability, the designer and manufacturer of conventional and electrified vehicle propulsion solutions company said.

TerraTran has maximum power capability of up to 800 hp, or 597 kW, and torque capability up to 3,025 lb/ft (4,502 kg/m), 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, according to the company, with field tests conducted over around two years demonstrating that TerraTran delivers enhanced drivability, gradeability and manoeuvrability under demanding operating conditions.

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.

Kartik Ramanan, Executive Director, Global Off-Highway Sales, Customer Support and Service Engineering at Allison Transmission, said: “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.

“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.”
