Benefits and Features
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 engine with Stage V emission package is recommended for mines that require compliance with highest emission standards in underground applications or customers that require to drive down diesel particulate matter and NOx emission to near-zero while improving overall air quality and maintaining a high machine performance. After-treatment components are carefully guarded and heat wrapped. The system uses regeneration to manage emissions inside the Clean Emissions Module (CEM). This solution requires the use of 15 PPM ultra-low sulfur diesel and CJ-4 low ash engine oil.
The engine with optional Ventilation Reduction Package is also available. The VR Package focuses on diesel particulate matter and it incorporates selective engine hardware and software to minimize diesel particulate matter in the engine exhaust. A Cat Diesel Particulate Filter (wall flow filter or flow through filter) can be used with the VR engine package. The filters compliment the VR engine by further reducing particulate matter in the exhaust. This solution requires the use of 15 PPM ultra-low sulfur diesel and CJ-4 low ash engine oil.
Optional Tier 3 equivalent and Stage IIIA equivalent engine is also available.

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.
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.
Automatic brake modulation offers a smoother ride and greater control, allowing the operator to concentrate on driving.
The AD45 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.
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.
Optional Enclosed Cab
Optional sound-suppressed ROPS cab provides a quiet, secure and comfortable air-conditioned working environment with fresh, pressurized, temperature-controlled air circulation.
Ergonomic, fully adjustable suspension seat provides optimal operator comfort. Thick cushions reduce pressure on lower back and thighs. Wide, retractable seat belts provide a secure, comfortable restraint.
Comfort wheel with tilt steering provides a comfortable driving position, secure grip and greater control.
Cat Electronic Monitoring System (Cat EMS) continuously provides critical machine data to keep the machine performing at top production levels. Displays are backlit for easy viewing. The Stage V model offers additional emission display allows emission status monitoring.
Additional camera mounted on the right hand side enhances operator visibility for the EU Stage V model and along with the reverse and cab loading cameras (optional for other machines) further assists operators to navigate the truck safely.
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
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 specific application.
Cat truck bodies are designed for optimal strength, capacity and durability. Drawing on years of experience in truck body design, Cat Truck Bodies are designed for long service life and low cost per ton.
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 16 seconds for raise and 21 seconds for lower.
Truck Payload Management System (TPMS)
The optional TPMS system calculates the payload the truck is carrying and determines truck cycle times. It now offers payload scoreboards on both sides of the truck providing the LHD operator with visual real time payload data.
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.
This system provides steering and oscillation and enables the truck to maintain all wheel ground contact in rough terrain.
Two independent variable rebound suspension cylinders dissipate haul road forces for longer frame life and a comfortable ride.
