  • 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 11 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.

Current Offers

Fuel efficient SR Hybrid Drive

The SR Hybrid Drive system is fully regenerative. During braking or retarding, electrical motors become generators and feed power back into the electrical system. This allows for up to 45% less fuel consumption than comparably sized mechanical drive wheel loaders. 

Handles multiple site duties

If your operation involves frequent equipment relocations, you’ll love this loader. It can keep the pit floor clean and level without support equipment, offers outstanding mobility and travel speed, and handles berm maintenance, road repair and cutting ramps. 

Greenhouse gas reduction (Tier 4 compliance)

The SR Hybrid Drive system efficiency gains, from the regenerative braking and the energy storage system, reduce fuel burn, which can result in a substantial CO² reduction per ton of material moved as compared to a mechanical drive.
