  • Structural

    Frames are fabricated from high strength, low-alloy steel with excellent weld characteristics and extreme low temperature properties. The front axle is an integral, fixed part of the front frame. The rear axle center oscillates eight degrees.

    Unique forged ball and socket joints are utilized in multiple pivot locations (lift arms, rear axle, frame articulation, hoist cylinders). These joints are superior in absorbing and distributing multi-directional stresses. Features easily replaceable brass liners for long life and easy maintenance.

    High strength castings are used in key areas of fabricated structures to reduce stress and improve structural life.

WX22H Underground hard rock haulage

The WX22H hybrid LHD uses proprietary KESS technology designed for the hard rock environment. This workhorse is engineered to help reduce fuel consumption and lower total operating costs due to fewer operating mechanical parts.

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.

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.
