User manual KOMATSU WA150-5 BROCHURE

[. . . ] Under deceleration, the HST system acts as a dynamic brake on the mechanical drive system. The dynamic brake can hold the loader in position on most workable slopes. This can be an advantage in stockpiling and ramp loading. As the machine moves and gains ground speed, the torque demand decreases and the low speed motor is effectively removed from the drive system by a clutch. [. . . ] The monitor is located behind the steering wheel and displays various different machine functions including fluid/filter change intervals and troubleshooting memory display functions. The main gauges are analog type for easy viewing and other functions utilize light symbols or LCD readouts. nipple Full Side-Opening Gull-Wing Engine Doors Ground level engine service and daily service checks are made easy with the gas spring assisted full side opening gull-wing doors. hose O-ring Cathion Electrodeposition Primer Paint/Powder Coating Final Paint Cathion electrodeposition paint is applied as a primer paint and powder coating is applied as a topcoat to the exterior metal sheet parts. This process results in a durable rust-free Parking Brake Service Brakes machine, even in the most severe environments. Some external parts are made of plastic to provide long life and high impact resistance. Sealed DT Connectors Extended Service Interval Swing-Out Radiator The new Komatsu cooling system is isolated from the engine to provide more efficient cooling and low noise. The swing-out hydraulic fan allows the operator to quickly clean out the cooling system. The radiator, air-to-air cooler and oil cooler are mounted side-by-side for more efficient cooling and easy cleaning. A fully-opening, gas spring assisted rear grill gives the operator excellent access to the swing-out fan and coolers. Extended engine oil change interval: 250 H 500 H Main harnesses and controller connectors are equipped with sealed DT connectors providing high reliability and dust and corrosion resistance. Komatsu Components Komatsu manufactures the engine, transfer case, differentials and Komatsu Components Engine Extended drive shaft greasing interval: 1, 000 H 4, 000 H High-rigidity Frames The front and rear frames along with the loader linkage have high rigidity to withstand repeated twisting and bending loads to the loader body and linkage. Both the upper and lower center pivot bearings use tapered roller bearings for increased durability. The structure is similar to those of large sized loaders and the reinforced loader linkage ensures high strength. electric parts on this wheel loader. Komatsu loaders are manufactured with an integrated production system under a strict quality control system. Front axle Transfer Rear axle Overrun Prevention System When the machine descends a slope of six degrees or less, maximum travel speed is automatically restricted to approximately 43 km/h 27 MPH, for safety protection against damage of power train components and brakes by sensing the travel speed and controlling the discharge amount of the HST pump and motor. When the machine descends a steep slope and the travel speed reaches 40 km/h 25 MPH, the caution lamp lights up to inform the operator to reduce the travel speed. Note: When the machine descends a steep slope, the use of the service brake is necessary to limit travel speed. 6 7 WA150-5 W HEEL L OADER Tiltable Steering Column The operator can tilt the steering column to allow maximum comfort and control. The two-spoke steering wheel allows maximum visibility of the monitor panel and forward work environment. WHEEL LOADER Comforts of Home The large cab allows room for a large lunch box holder and a variety of cup holders. Optional air conditioning and the optional AM/FM stereo cassette system create a comfortable and controlled work environment. WA150-5 OPERATOR COMFORT New Cab Layout Komatsu's new cab layout provides the operator with a roomy, quiet and efficient work environment. The low noise level inside the cab leads the industry at 70 dB(A) and loader controls are ergonomically designed to reduce operator fatigue and increase productivity. Easy-to-operate Loader Control Mono-lever A new mono-lever using PPC (Proportional Pressure Control) allows the operator to easily operate the work equipment, to reduce operator fatigue and to increase controllability. The adjustable wrist rest provides the operator with a variety of comfortable operating positions. Two Door Walk-Through Cab Entry and exit into the new Komatsu cab starts with sloped staircase type steps and large diameter handrails for added safety and comfort. The large cab doors are rear-hinged to open 130 degrees offering easy entry/exit and will not hamper visibility when operating the machine with the doors latched open. A wide pillar-less flat glass provides for excellent visibility. The wiper arm covers a large area to provide great visibility even on rainy days. Electrically Controlled Directional Lever The operator can change direction with a touch of his fingers without removing his hand from the steering wheel. Solid state electronics makes this possible. Low-noise Design Operator noise: 70 dB(A) The large cab is mounted with Komatsu's unique ROPS/FOPS viscous mounts. The low-noise engine, hydraulically driven fan, and hydraulic pumps are mounted with rubber cushions, and the cab sealing is improved to provide a quiet, low-vibration, and comfortable operating environment. Pressurization in the cab keeps dirt out further enhancing the operator's comfort. 8 9 WA150-5 W HEEL L OADER WHEEL LOADER WA150-5 SPECIFICATIONS ENGINE Model .
