[. . . ] 990H Wheel Loader ® Engine Engine Model Gross Power Net Power Buckets Bucket Capacities Operating Specifications Rated Payload Operating Weight Cat® C27 ACERTTM 512 kW 687 hp 468 kW 627 hp 8. 4-9. 2 m3 15 tonnes 77 842 kg (11-12 yd3) 16. 5 tons 171, 642 lb 990H Wheel Loader State-of-the-art design and superior quality allow you to maximize productivity. Power Train Cooling System Structures The integrated structural components of the 990H provide a stable, well-balanced system. The full box-section rear frame, four plate loader tower, Z-bar loader linkage and solid steel lift arms work together to enable a loaded bucket to move smoothly through the lift and dump cycle. The Next Generation Modular Cooling EPA Tier 3/EU Stage IIIa compliant and System with Air-to-Air Aftercooling with MEUI, an air-to-air aftercooler, System has been added to the 990H to axle-shaft brakes, impeller clutch torque help meet emissions requirements and converter and planetary electronic power improve efficiency, serviceability, shift transmission forms a responsive, visibility and sound levels. 4 Application Truck Match Increased performance and good pass matching make the 990H a versatile performer. [. . . ] Incorporates innovations for operator comfort and productivity include spaciousness, outstanding visibility, interior sound levels below 75 dB(A), a standard coat hook, cup holder, storage bin, tinted glass and intermittent wet-arm wipers. Is a revolutionary system that integrates steering and transmission into a single controller. Simple side-to-side motions of the operator's left arm turn the machine right or left. Transmission shifting for forward, neutral, reverse is controlled by the operator's fingers and gear selection is controlled by the operator's thumb. These factors combine to produce a fluid motion that reduces effort and allows the operator to work the machine for long periods of time with little or no fatigue. Operates the impeller clutch torque converter for approximately the first inch of travel, then engages the brakes. With air suspension and retractable seat belt, including (4) trainer seat and lapbelt, are designed for comfort and support. Seat cushions reduce pressure on the lower back and thighs while allowing unrestricted arm and leg movement. They adjust fore and aft, with a heightadjustable armrest so operators of any size can find a comfortable operating position. 6 Electronic Monitoring System III (EMS III). Continually monitors various machine systems through three instrument clusters and provides a three-level warning system to alert the operator of immediate or pending problems. EMS III shares information with the engine, hydraulic and transmission controls that can be used during servicing to simplify service and troubleshooting. Detects and warns the operator of extreme axle cooling oil temperature through indicator light. Allows the operator to preset the engine speed for a variety of applications. Turns the Rimpull Control System on and off. 11 Optional Payload Control System II. Offers on-the-go weighing to assist in loading trucks more accurately. Is used by the operator to keep track of Payload Control System II information. Is used in roading, load and carry and other applications where load retention, spillage and operator ride may be a problem. It provides lift arm suspension system by placing an accumulator in the lift arm circuit. Allows quicker cycle times by shifting from 1st forward to 2nd reverse. Feature pilot-operated lift and tilt circuits with a two lever controller that is floor-mounted and adjustable. The automatic bucket positioner can adjust to the desired loading angle and visual spotting is not required. 12 11 10 10 Rimpull Control System (RCS). Each setting corresponds to a maximum allowable impeller clutch pressure and is user programmable. [. . . ] · FOPS meets SAE J231 JAN81 and ISO 3449:1992 Level II criteria. · The operator sound exposure Leq (equivalent sound pressure level) measured according to the work cycle procedures specified in ANSI/SAE J1166 OCT98 is 72 dB(A), for the cab offered by Caterpillar, when properly installed, maintained and tested with the doors and windows closed. · Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in noisy environment. · The exterior sound pressure level for the standard machine measured at a distance of 15 m (49. 2 ft) according to the test procedures specified in SAE J88 JUN86 mid-gear-moving operation is 82 dB(A).
