Power Train ­ Engine The Cat C32 engine with ACERTTM Technology uses advanced engine technology to reduce emissions without after-treatment. The turbocharged, aftercooled 12-cylinder engine has higher horsepower and faster response for superior performance in demanding applications. 4 ® Power Train ­ Transmission The Cat seven-speed power shift transmission matched with the Cat C32 engine with ACERT Technology provides constant power and efficiency over a wide operating speed range for optimal power train performance. [. . . ] Extended life friction material has double the wear life of standard brakes and is twice as resistant to glazing for more consistent braking power with less noise. Cat oil-cooled disc brakes are designed with large discs and plates for reliable, adjustment-free operation and performance. Brakes are completely enclosed and sealed to prevent contamination and reduce maintenance. 10 ARC 1 2 1 2 3 4 5 6 7 8 Service Brake Sensor Engine Sensor ARC ARC Switch Brakes Service Brakes Axle Speed Sensor TCS TCS 6 7 8 3 7 5 4 6 Automatic Retarder Control (ARC). Standard ARC electronically controls braking on grade to maintain engine at approximately 1, 950 rpm (adjustable from 1, 850-1, 950 rpm. ARC is deactivated when the operator applies the brakes or throttle. 2500 2000 Engine Speed (rpm) · Superior Control. Automatic brake modulation offers a smoother ride and better control in slippery conditions, allowing the operator to concentrate on driving. ARC increases operating ease, resulting in greater operator confidence with less fatigue. Automatically activates ARC when engine speed exceeds factory preset levels, regardless of operator inputs, to avoid potentially damaging engine overspeeds. Traction Control System (TCS) (optional). Electronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions. If slippage exceeds a set limit, the oil-cooled disc brakes engage to slow the spinning wheel. Torque is then automatically transferred to the wheel with better traction. Normal differential action provides superior maneuvering and control in slippery conditions. Optional Compression Brake is integrated with Automatic Retarder Control (ARC) to provide up to 35 percent higher downhill travel speed and reduce wear on brake components. 1500 1000 500 0 10 20 30 40 50 Time (Seconds) 60 70 With Automatic Retarder Control (average speed, 1950 rpm) With Manual Retarder Control (average speed, 1730 rpm) · Faster Speeds. ARC allows the operator to maintain optimum engine speeds for up to 15 percent faster downhill hauls and greater productivity. 11 Serviceability Less time spent on maintenance means more time on the haul roads. Servicing Ease. Easy access to daily service points simplifies servicing and reduces time spent on regular maintenance procedures. Enhanced serviceability and extended 500-hour service intervals are designed to increase machine availability and productivity. Easy stairway access to engine, air filters, steering hydraulic tank and radiator. Allows convenient servicing to tanks, filters, drains, battery disconnect and engine shutdown. Engine prelubrication provides engine oil pressure prior to engine cranking. This reduces engine dry and cold start wear, and reduces engine component wear. Fast Fill Service Center (optional). Wiggins fast fill service center features high-speed fuel and oil exchange and clustered connections for fluids for fast, accurate servicing and reduced downtime. Extends oil change intervals and reduces waste oil handling by continuously burning oil from the engine oil pan through normal engine operation. [. . . ] The steering hydraulic system is separate from the main hydraulic system to prevent crosscontamination and overheating. A battery disconnect switch, located directly above the front bumper, provides ground-level lockout of the electrical system. Wide stationary stairways and platforms on both sides of the machines, allow easy ingress and egress. A stairway lamp illuminates the cab access stairs and can be activated at ground level during entry and shut off with a switch in the cab. · Slip resistant surfaces · 75 mm (3 in) wide orange threepoint operator restraint · Heated, wide-angle mirrors · Body raised indicator · Guard rails · Reverse neutralizer when dumping · Low interior sound level · Service platform level transmission, hoist and steering disable switch · Service platform level starter disable switch 17 Engine Engine Model Gross Power ­ SAE J1995 Net Power ­ SAE J1349 Net Power ­ ISO 9249 Net Power ­ 80/1269/EEC Number of Cylinders Peak Torque Bore Stroke Displacement Cat® C32 ACERTTM 758 kW 1, 016 hp 700 kW 938 hp 700 kW 938 hp 700 kW 938 hp 12 4716 N·m 3, 478 lb ft 145 mm 5. 7 in 162 mm 6. 4 in 32. 1 L 1, 959 in3 Transmission Forward 1 Forward 2 Forward 3 Forward 4 Forward 5 Forward 6 Forward 7 Reverse 10. 5 km/h 14. 3 km/h 19. 3 km/h 26. 1 km/h 35. 4 km/h 47. 6 km/h 64. 5 km/h 12. 1 km/h 6. 5 mph 8. 9 mph 12 mph 16. 2 mph 22 mph 29. 6 mph 40. 1 mph 7. 5 mph · Maximum travel speeds with standard 27. 00R49 (E4) tires. · Power ratings apply at 1, 750 rpm when tested under the specified condition for the specified standard.
