Structures

Proven Durability and Reliability

Front Frame

The front frame design features a large box section and wide,

stiffframe beams to handle torque loads. The divergent frame

design decreases stress in the hitch area and optimizes

suspension geometry. The frame design makes maximum

useofrobotic welding for increaseddurability.

Rear Frame

The four plate box constructed rear frame minimizes stress

concentrations and provides low weight with long service life.

Dump Body

Extensive use of 450 Brinell hardened steel provides excellent

impact and wear resistance. Body top rail design reduces

material spillage at the loading area.

Diverging flow construction gives clean load ejection which

maximizes production and avoids the waste of material carry back.

Suspension

The three-point oscillating axle front suspension provides

unparalleled ride quality. It also protects the truck from adverse

road conditions by absorbing shock loads that would reach

theframe.

Articulating/Oscillating Hitch

The articulating hitch provides the truck with steering

articulation, andthe oscillation ensures all-wheel ground

contactin rough terrain.

Hitch Construction

The two-piece construction of the hitch features a durable

caststeel head bolted to a hard wearing forged steel tube.
