Caterpillar has launched its new wheel tractor scrapers at CONEXPO.

The new Cat 620 K Series Wheel Tractor scrapers "refine the design of their H Series predecessors," the machinery manufacturer said.

This new series implements a number of new features such as high-pressure steering, engine over-speed protection, tyre spin reduction, diff lock engagement protection, machine/ground-speed control, and payload estimators.

It has also focused on payload, with the open-bowl 621K and open-bowl, twin engine 627K carrying 26.2 tonnes and the elevating 623K carrying 25.1 tonnes.

The new models come with a number of enhancements such as advanced cushion hitch, which used new software to dampen end of stroke movement of the load cylinder for a smoother ride.

A hydraulic system refinement has simplified the bowl quick-drop function, whilst draft arm overflow guard divert material away from the bowl sides.

An auto-stall assists in quickly bringing the transmission to operating temperatures for faster transitions from torque convertor drive.

The scrapers engine over-speed protection uses sensors that anticipate over-speed conditions and automatically apply compression or service brakes to keep engine speed within the target range.

The machines are all drive by a Cat C13 ACERT engine, and have a net power of 304kW.
