  • Controlled Throttle Shifting - Regulates engine RPM, torque converter lock-up and transmission clutch engagement for smoother shifts and longer component life.

  • Economy Shift Mode - Decreases fuel consumption, lowers noise levels and potentially longer engine life.

  • Directional Shift Management - Regulates engine speed to prevent damage caused by high speed directional changes.

  • Body-up Shift Inhibitor - Prevents the transmission from shifting above a pre-programmed gear without the body fully lowered.
Electronic Technician (Cat ET)

Cat ET service tool provides service technicians with easy access to stored diagnostic data through Cat Data Link to simplify problem diagnosis and increase availability.

Overspeed Protection

The Automatic Retarder Control (ARC) system provides engine overspeed protection. The ARC will engage the brakes if the following conditions exist at the same time:

  • An unsafe engine speed is reached.
  • The ARC on/off switch is in the ON position or the OFF position.
  • The throttle is being depressed by the operator. If the transmission is in top gear, the lockup clutch is deactivated in order to protect the engine against an engine overspeed condition.

Cat Brake System

Integrated Braking System

The Cat oil-cooled braking system delivers reliable performance and control in the most extreme underground mining conditions. The integrated system combines the service, secondary, parking brake and retarding functions in the same robust system for optimum braking efficiency.

Oil-Cooled Multiple Disc Brakes

Four-wheel, forced oil-cooled, multiple disc service brakes are continuously cooled by a water-to-oil heat exchangers for non-fade braking and retarding performance. They are also completely enclosed to prevent contamination and reduce maintenance.

Automatic Retarder Control (ARC)

Electronically controls retarding on grade to maintain optimum engine RPM and oil cooling. Additional braking may be applied using the manual retarder or the brake pedal. ARC also allows the operator to maintain optimum engine speeds for faster downhill hauls and greater productivity. The ARC automatically activates when engine speed exceeds factory preset levels.

Superior Control

Automatic brake modulation offers a smoother ride and greater control, allowing the operator to concentrate on driving.

Operator Comfort

The AD60 operator station is ergonomically designed for total machine control in a comfortable, productive and safe environment. All controls, levers, switches and gauges are positioned to maximize productivity and minimize operator fatigue.

  • Ejector Body

The ejector body offers clean load ejection and can be removed and switched with a dump body for greater machine versatility.

Body Selection

Selection of the right body depends on material, haul road, and dump conditions. The better the match of body to application, the greater the efficiency. Its diverging flow design gives clean load ejection, which maximizes production and avoids material carryback.

Body/Chassis Integration

Cat truck bodies are designed and matched with the integrated chassis system for optimum structural reliability, durability and long life.

Fast Hoist Cycle Times

Single-stage hoist cylinders provide fast dump cycle times of 12 seconds for raise and 24 seconds for lower.

Truck Payload Management System (TPMS)

The optional TPMS system calculates the payload the truck is carrying and determines truck cycle times.


Frame Design

The frame uses box-section design with stiff frame beams to resist twisting forces giving it a longer structural life.

Articulating/Oscillating Hitch

This system provides steering and oscillation and enables the truck to maintain all wheel ground contact in rough terrain.


Ground-Level Service Access
