The Cat Control System

We have led the way in increasing the productivity of battery powered mining equipment.


State-of-the-Art Drive Technology

Optional HiPAC 10 VFD - The Cat HiPAC 10 is a DC to AC variable-frequency inverter control that drives high-performance AC electronic motors, which have a superior speed-torque characteristics.


Mine Duty, 37 kW/50 hp Tram Motor

The scoop is equipped with a 50 hp, 110 V DC, class H insulation series wound traction motor.


Explosion Proof, 11.9 kW/16 hp Pump Motor

All Cat utility scoops feature large hydraulic fluid reservoirs for maximum cooling capacity. Each reservoir is equipped for easy fluid-level monitoring.


Heavy-duty Drive Train

With options and features like full inboard planetary axles and bulletproof outboard and hub-end planetary axles, the Cat Scoop is the right combination for any application.


Human-factor Engineered Operator’s Compartment

For long-shift productivity, operator comfort is paramount for maintaining a safe working environment.


Heavy-duty Center Section

To provide superior stability in tough conditions, the scoop offers ball bearing oscillation. The problems associated with three-point-hitch style oscillation are eliminated with the robust design of the pivot section.


Environmentally Responsible

The Cat Diesel Power pack, in both permissible and non-permissible configurations, is the cleanest power pack available for the underground mining environment.
