Caterpillar’s new 120K
maintenance grader

Launched globally towards the end of 2009, Caterpillar’s new 120K maintenance grader, which forms part of the upgraded K-Series range now available in South Africa, replaces the Cat 120H model. It comes to the market with increased operational enhancements and a fuel efficient Cat C7 ACERT engine meeting Tier II emission standards.

“The H-Series has been the industry standard in a variety of heavy construction, road building and governmental applications,” explains Barloworld Equipment product manager, Johan Hartman, “and the K-Series continues this tradition.”

Key features on the 120K include VHP (variable horsepower); electronic throttle control; automatic idle control; increased torque; air-to-air after cooling; improved ease of operation; plus an upgraded dash cluster and monitoring system.

The new Cat 120K also has a greater base weight of 12,700 kg compared to the 120H’s 11,358 kg, with the VHP range also rising from 93/104 kW to 93/108 kW. The standard blade length remains the same at 3.7 m.

Maintenance cost savings on the K-Series are achieved through innovative engineering, an example being the 120K’s oil-bathed, air actuated and spring-released brakes. Located at each tandem wheel, the design eliminates braking loads on the power train and reduces servicing time. Additionally, the large brake surface provides dependable braking capability and extended life before rebuild.
