Simple and Reliable Hydraulic System

The hydraulic system is a proven and reliable design with fewer parts that other OEMs. The system utilises a single tank, providing one common source of fluid for steering, braking and hoist actuation. In-line, replaceable filtration elements provide protection from hydraulic system contamination, making the system easier to service.

Structurally Enhanced Frame Design

By using advanced computer-aided design, finite element analysis, and full-scale dynamic and static testing, the frame design has been structurally enhanced to carry more weight and provides the highest structural reliability in the industry.

Hydrair II® Hydropneumatic Suspension

Hydrair II® is a suspension system that utilises four nitrogen-over-oil cylinders. This suspension system is designed to maximize machine productivity by providing the operator with a smooth and comfortable ride.
