Power Train – Engine The Cat ® C27 Engine is built for power, reliability and efficiency. ACERT™ Technology The Cat C27 is U.S. EPA Tier 2 and EU Stage II compliant. It delivers higher power and greater durability for maximum hauling performance in the most demanding mining applications. Complete system integration of the engine and transmission optimizes performance and efficiency. Power Increase The 21.8% power increase over previous models provides unequalled lugging force during acceleration and less down­ shifting on grade. Improved software and updates in engine technology further...

Power Train – Transmission More power to the ground for greater productivity. Mechanical Power Train The Cat® mechanical drive power train and power shift transmission provide unmatched operating efficiency and control on steep grades, in poor underfoot conditions, and on haul roads and drives with high rolling resistance. Transmission The Cat seven-speed planetary power shift transmission is matched with the direct-injection C27 engine with ACERT™ technology to deliver constant power over a wide range of operating speeds. Robust Design Designed for rugged underground mining conditions, the...

Cat Brake System Superior control for operator confidence. 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 exceptional, non-fade braking and retarding performance. Brake Design Brakes are...

Operator Comfort Ergonomically designed for all-day comfort, control and productivity. The AD55B 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. Protective Structure Integral to the cab and frame, both the Rollover Protective Structure (ROPS) and Falling Objects Protective Structure (FOPS) are resiliently mounted to the mainframe to isolate the operator from vibration for a more comfortable ride. Standard...

Truck Body Systems Rugged performance and reliability in tough underground mining applications. Cat Truck Bodies Caterpillar offers two specific body styles for the most efficient hauling solutions at the lowest cost-per-ton. • Dump Body • Ejector Body The ejector body can now be easily removed and a dump body fitted 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. Your Cat dealer can help you select the right body system for your site...

Structures Rugged Cat structures – the backbone of the AD55B’s durability. Frame Design The frame uses box-section design with stiff frame beams to resist twisting forces. Materials and weld joints are matched to optimize the structural life of the frame. Articulating/Oscillating Hitch This system provides steering and oscillation and enables the truck to maintain all wheel ground contact in rough terrain. Suspension System Two independent variable rebound suspension cylinders dissipate haul road forces for longer frame life and a comfortable ride. Serviceability More time for production....
