Kinetic Energy Storage System (KESS)

During propulsion, diesel energy is converted to electricity. Energy flows from the motors and is stored in the KESS unit. During acceleration, both the diesel engine and the energy stored in the KESS can provide the equivalent of one 400 HP engine being boosted by another 550 HP engine.

A path toward electrification

Using KESS hybrid technology, the WX18H LHD consumes up to 30 percent less fuel than diesel machines. This hybrid technology reduces the need for ventilation and can help you drive toward zero emissions and electrification of your mining operation.

Lower operating costs

With less fuel being consumed, your mine operations can run more efficiently. The SR hybrid drive system in the WX18H and WX22H LHDs has fewer operating mechanical parts subject to wear and tear. Plus, costs related to ventilation needs are reduced.
