US-based Torvec has entered into a contract with Eastern Mining & Industrial Supply to develop, evaluate, manufacture and sell Torvec’s IsoTorque differential technology in mining shuttle cars.

Under the contract, Torvec will design and build a prototype IsoTorque unit for installation in a 21 SC model mining shuttle car.

The firms have agreed that Torvec will sell 100% of the differential requirements for all 21 SC model mining shuttle cars remanufactured by Eastern exclusively, once the prototype phase is completed.

Eastern vice-president David Mayo said the IsoTorque differential will allow the vehicles to manoeuvre more easily and may prevent premature failures in the car’s driveline.
