Cat Underground Mining Trucks AD45B
Product Feature
Power Train – Engine – The Cat C18 Engine is designed for power, reliability and efficiency.
The Cat C18 engine provides efficient fuel management for quick response, high productivity and exceptional service life. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times. Mechanically Actuated, Electronic Unit Injection (MEUI™) high-pressure, direct injection fuel system electronically monitors operator demands and sensor inputs to optimize engine performance. Air-to-air aftercooling provides improved fuel economy by packing cooler, denser air into cylinders for more complete combustion of fuel and lower emissions. Turbo is water cooled to improve performance and service life.
The Cat C18 engine features the optional Ventilation Reduction (VR) Package. The VR Package incorporates selective engine hardware and software to minimize diesel particulate matter in the engine exhaust. Engines equipped with the VR Package feature a significant ventilation rate reduction, maintains fuel consumption, and maintained or improved product performance. VR Package availability is subject to regional regulatory compliance. Optional engine with emissions equivalent to U.S. EPA Tier 3 and EU Stage IIIA is also available.
A Cat Diesel Particulate Filter can be used with the VR engine package. This filter compliments the VR engine by further reducing particulate matter in the exhaust. Requires the use of ultra-low sulfur diesel (15 ppm) and CJ-4 low ash engine oil.
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 C18 engine to deliver constant power over a wide range of operating speeds.
Robust Design
Designed for rugged underground mining conditions, the proven planetary power shift transmission is built for long life between overhauls.
Lock Up Torque Converter
Combines maximum rimpull and cushioned shifting of torque converter drive with the efficiency and performance of direct drive. When engaged, lock-up provides superior power train efficiency by delivering more power to the wheels.
Lock-Up Clutch
Quickly releases and re-engages to reduce power train torque loads for smoother shifting, long life and a more comfortable ride.
Smooth Shifting
Individual clutch modulation provides smooth clutch engagements to optimize performance and extend clutch life.
Final Drives
Cat final drives work as a system with the planetary power shift transmission to deliver maximum power to the ground. Built to withstand the forces of high torque and impact loads, final drives provide high torque multiplication to further reduce drive train stress.
Full Floating Axles
Full floating axles relieve internal stresses and increase durability. Rolled splines also provide increased service life.

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.
