The Cat Control System

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

Our control system eliminates commutating coils and capacitor banks and is able to provide a microprocessor-based motor controller. Using the dash-mounted diagnostic display and the handheld calibrator/diagnostic unit, difficulties can be overcome in short order.

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.

It is up to 14% more efficient than traditional DC motors. This means higher loaded tram speeds, more responsive hydraulic functions and more work per battery charge.

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.

An Optional 100 hp AC tram motor is available with the HiPAC 10 VFD Control System.

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.

The machines are provided with 10-micron return line filtration and a magnetic particle sump strainer. For long life and dependability, the main imple­ment pumps are helical gear, fixed displace­­ment. Dash-mounted gauges provide the operator with continuous monitoring of the status of the hydraulic system. An optional 35 kW (47 hp) AC Pump motor with HiPAC 10 VFD control system is available.

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.

For unparalleled speed and maximum reliability, the SU488 offers dual 37.3 kW (50 hp) tram motors.

Human-factor Engineered Operator’s Compartment

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

At Caterpillar, ergonomics is not just another marketing buzzword. Controls are placed in a logical, easy-to-reach position and are easily operated from the fully padded, adjustable seat.

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.

High-strength, low-alloy steel bearing attachment faces and quality ANSI/AWS welding help provide the reliability that our customers demand. The articulation joint features hardened spherical bushings to ensure even load distribution to the high-strength, hardened articulation pins.

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.

Alternate engines are available depending on application and geographical regions.
