Control System

Controlled Productivity

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.

Drive Technology

High-performance AC power for more efficiency

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.

Tram Motor

Higher loaded tram speeds

The scoop is equipped with a 37.3 kW (50 hp), 110V DC, class H insulation series wound traction motor. An optional 74.6 kW (100 hp) AC tram motor is available with the HiPAC 10 VFD Control System.

Pump Motor

Explosion proof with 11.9 kW/16 hp

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.

Drive Train

Unparalleled speed and maximum reliability

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 L offers dual 37.3 kW (50 hp) tram motors.

Axle Diff-Lock

4-wheel drive on-demand

Four-wheel drive for when conditions get tough, planetary axles with wet disc service brakes, helical, parallel gearbox, spring applied, hydraulically-released parking brakes and other features all combine to provide rock climbing gradeability. With the ability to engage a battery from below grade, and to vary the ground clearance of the battery in undulating conditions, the Cat scoop is able to thrive in varying mining environments.

Center Section

Heavy-duty construction for maximum reliability

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.

Operator Comfort

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.

Safety

Designed with safety as top priority

All Cat battery-powered face haulers and scoops are designed with safety and productivity as number one priorities. The scoop safety features include:

  • Panic strips in the operator’s compartment
  • Emergency stop buttons
  • Fire suppression (automatic or manual activation) on both sides of the machine
  • Steering lockout
  • Proximity detection (on request)
  • Spring applied, hydraulic release brakes
  • Two key start functions
  • Warning gongs
  • Start up audible alarms (optional)
  • Canopy over operator’s compartment
