Power Train – Engine
The Cat C15 Engine is built for power, reliability and efficiency.The Cat C15 engine provides unequalled lugging force while digging, tramming and traversing steep grades. 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. Oil coiled pistons increase heat dissipation and promote longer piston life. The crankshaft is forged and induction hardened for long-term durability. The Cat C15 engine features the optional Ventilation Reduction 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 U.S. EPA Tier 3 and EU Stage III compliant engine 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 15 PPM ultra low sulfur diesel and CJ-4 low ash engine oil.
Power Train – Transmission
More power to the ground for greater productivity.
Mechanical Power TrainThe 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.
TransmissionThe Cat four-speed planetary power shift transmission is matched with the C15 engine to deliver constant power over a wide range of operating speeds.
Robust DesignDesigned for rugged underground mining conditions, the proven planetary power shift transmission is built for long life between overhauls.
Lock Up Torque ConverterCombines 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 ClutchQuickly releases and re-engages to reduce power train torque loads for smoother shifting, long life and a more comfortable ride.
Smooth ShiftingIndividual clutch modulation provides smooth clutch engagements to optimize performance and extend clutch life.
Final DrivesCat 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 AxlesFull floating axles relieve internal stresses and increase durability. Rolled splines also provide increased service life.
Engine/Power Train Integration
Intelligent electronics for overall optimal performance.
Cat Data Link
Electronically integrates machine computer systems to optimize overall power train performance, increase reliability and component life, and reduce operating costs.
- 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.
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
Superior control for operator confidence.
Integrated Braking SystemThe 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 BrakesFour-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 ControlAutomatic brake modulation offers a smoother ride and greater control, allowing the operator to concentrate on driving.
Ergonomically designed for all-day comfort, control and productivity.The AD30 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 StructureIntegral 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 CabOptional sound-suppressed ROPS cab provides a quiet, secure and comfortable air-conditioned working environment with fresh, pressurized, temperature-controlled air circulation.
Suspension SeatErgonomic, 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.
Steering ColumnComfort wheel with tilt steering provides a comfortable driving position, secure grip and greater control.
Monitoring SystemCat 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.
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.
The ejector body can now be easily removed and a dump body fitted for greater machine versatility.
Body SelectionSelection 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.
Body DesignCat truck bodies are designed for optimal strength, capacity and durability. With improved design and the use of Hardox steel, longer service life and lower cost per ton figures are now evident.
Body/Chassis IntegrationCat truck bodies are designed and matched with the integrated chassis system for optimum structural reliability, durability and long life.
Truck Payload Management System (TPMS)The optional TPMS system calculates the payload the truck is carrying and determines truck cycle times.
Fast Hoist Cycle TimesSingle-stage hoist cylinders provide fast dump cycle times of 10.5 seconds for raise and 11.2 seconds for lower.
Rugged Cat structures – the backbone of the AD30’s durability.
Frame DesignThe frame incorporates a box-section design with wide and stiff frame beams to handle torque loads. The frame design decreases stress in the hitch area and optimizes suspension geometry. Materials and weld joints are matched to optimize the life of the structure.
Articulating/Oscillating HitchThe articulating hitch provides the truck with steering articulation and the oscillation ensures the truck maintains all wheel ground contact in rough terrain. Hardened steel pins, taper roller bearings and oscillating stops allows the rear frame to move independently from the front frame.
