New model designed to combine reliable performance with simple, low cost-per-hour operation
COMPLEMENTING the existing Cat motor grader offering, the new Cat 120 GC model is said to offer the optimum balance of high-performance features with reduced fuel consumption, low maintenance costs, and easy-to-operate controls, for use in a range of low- to medium-duty applications.
The machine’s fuel-efficient Cat C4.4 engine, powershift transmission and balanced machine design ensure appropriate drawbar power to the ground, with electronic throttle control helping to improve grading productivity by adapting engine power and torque to the demands of the application.
With precisely matched engine power ranges for the standard rear-wheel drive and optional all-wheel drive, standard Eco mode operation increases fuel economy by up to 5%, whilst the hydraulic cooling fan, with optional reversing fan for high-debris applications, only runs when necessary to further reduce fuel consumption.
With its familiar steering wheel and lever layout, consistent with the 120, 140 and 160K models, the hydraulic system provides more precise and predictable control for a consistent grade. Moreover, the transmission with torque converter eliminates the need for an inching pedal, so only throttle and brake pedals are required to simplify operation.
The drive system’s no-spin differential automatically unlocks in the turn to eliminate any input from the operator, and the parking brake automatically engages when the machine is in neutral and the service brake is disengaged.
Built with long-life machine structures for reliable operation, the 120 GC’s standard drawbar circle moldboard offers increased durability with hardened circle teeth and replaceable wear inserts protecting the main component structures.
Caterpillar say this design stays factory-tight to provide long-term precision grading, while the circle drive slip clutch option protects the drawbar, circle, and moldboard from potential damage if the machine strikes an immovable object.
Easy to maintain, a Circle Saver option reduces daily greasing requirements and repairs to the circle and pinion, whilst the grader’s new front axle design maximizes bearing life to minimize maintenance.
A narrow machine width of 2.4m (7.9ft) plus a choice of standard or low-profile cab to reduce overall transport height to 3.12m (10.25ft) improves machine transportability.
For operator comfort, the cab offers the option of either a mechanical or air-suspension seat, whilst the control console and steering wheel easily adjust to the operator’s preferences. Pressurized to prevent debris entry, the cab’s optional HVAC system circulates fresh air to prevent the windows from fogging.
A range of options, such as the Digital Blade Slope Meter which shows the operator the grade without relying on manual grade checkers, is available to increase machine flexibility and meet specific customer requirements.
Optional all-wheel drive increases traction and efficiency, with the increased engine power that comes with this option providing improved performance on slopes and in poor underfoot conditions.
The 120 GC also offers 3.0m, 3.7m, and 4.3m (10ft, 12ft, and 14ft) moldboard options to meet a range of coverage requirements, and a newly redesigned mid-mount scarifier improves visibility to the attachment while decreasing overall machine length.
To improve machine performance, the 120 GC features a common front bolster for a choice of front lift group, counterweight, or front blade option, which aids in spreading more material faster. The rear of the machine accommodates a ripper or towing hitch option.
