Caterpillar

DIFFERENTIAL STEERING Differential steering maintains full power on both chains for unparalleled steering even when the blade is fully loaded. When one chain accelerates, the other slows down accordingly. You benefit from greater maneuverability and shorter cycle times. You also get better load capacity, power and speed control.

LOAD SENSING The field proven circuit detects the load and continually adjusts the hydraulic power to optimize your efficiency. A specific equipment pump ensures adequate available hydraulic power. A single differential coupler sends 70% of the motor torque to the converter and 30% to a direct drive shaft. You benefit from more power on the ground.

COOLING SYSTEM The advanced modular cooling system has excellent cooling capacity with increased airflow, allowing the machine to operate in the most demanding environments. Double-pass cooling increases the relevant area to ensure maximum cooling capacity. The individual radiator bundles can be quickly replaced to facilitate maintenance operations.
