User manual ZENOAH KOMATSU WA1200-3 BROCHURE

[. . . ] Operator's safety is built into the cab with the use of a ROPS/FOPS canopy, a two-door system, and an emergency ladder. The Most Advanced Technology The dream has come true. Advanced Joystick Steering System (AJSS) with light, short strokes for perfect steering accuracy. Hi-Cab is extra long and wide to provide a comfortable work environment. The seated operator has a better view inside the body of a 240-ton haul truck. Oversized, obstruction-free windshield, side and rear windows provide a panoramic view of the work site. NET HORSEPOWER 1165 kW 1560 HP @ 1900 rpm OPERATING WEIGHT 205200 kg 452, 390 lb BUCKET CAPACITY 18. 0 ­ 35. 0 m3 23. 5 ­ 45. 8 yd3 Remote boom positioner is easy to set up. [. . . ] Once the positioner is set the bucket is smoothly stopped at the desired position with no shock. 300 ton 240 ton 6170 mm 200 ton 150 ton Variable Output Hydraulic System (VOHS) This self-adjusting system puts the power where needed. When digging, the available traction power increases and as a result the penetration force increases. When the boom is raised, the boom hoist circuit flow is increased to provide faster boom hoist cycle times. This system was designed to lower the machine's work cycle times. Hi-Cab To enhance the loading performance when using larger buckets with the extra dumping clearance and reach, the hi-cab is standard equipment. From his vantage point, 6170 mm 20'3" from the ground, the seated operator has a safe, unobstructed full view of the bucket and the inside of a 240-ton truck body. 6 7 WA1 200-3 WHEEL LOADER KOMATSU DESIGNED KOMATSU DESIGNED RELIABILITY RELIABILITY Integrating the latest technology in all areas of design, Komatsu has developed the WA1200-3 Mountain Mover as the most reliable, durable wheel loader for working in the harshest mining conditions. Exclusive Komatsu Design Features Power Train, Axles, Transmission, and Hydraulic Components The power train transforms 1165 kW 1560 HP into 1127 kN 115000 kg 253, 500 lb traction and 1274 kN 130000 kg 286, 600 lb breakout force. All components within the power train, from bolts to final gearing, are all Komatsu-designed. Designed to bear large loads and transmit large amounts of tractive power, Komatsu's full floating axle is used along with its planetary style transmission--another exclusive Komatsu feature with proven industry experience. The variable displacement hydraulic pump and hydraulic cylinders are also Komatsu-built components. Safe Durable Service Brakes The WA1200-3 uses Komatsudesigned sealed wet disc brakes. This proven design, coupled with a brake oil cooling system, provides reliable and durable final drive braking while downhill traveling with full loads and in all load and carry operations. Centralized Filter Layout Torque converter, transmission, engine oil, and fuel filters have been centrally located for ease of replacement from the ground. Quick Fluid Change-out System Hydraulic oil, transmission/torque converter oil, engine oil, and engine coolant can all be changed from the ground with a quickfill/change-out system. Wiggins Quickfill systems are used. Automatic Greasing System A microprocessor-based system ensures a preset supply of lubrication is delivered to all lube points at the proper intervals to help reduce maintenance costs. Rigid Frame Frame is designed to accommodate actual working loads, and simulated computer testing proves its strength prior to building. To increase frame reliability, steel castings have been incorporated at all frame pivot points to eliminate excessive welding lines. Steps, Ladders, Doors, Hinged Radiator Grille, Handrails Ladders and steps are arranged to provide safe access to each maintenance point. All doors are easy to open and provide accessibility for maintenance and cleaning. The radiator grille is a hinged design and opens as a door for easy access and cleaning. Safety handrails and steps are used at each maintenance point above ground level. 8 9 WA1 200-3 WHEEL LOADER OPERATOR'S OPERATOR'S COMPARTMENT COMPARTMENT Designed with the operator in mind, the operator's compartment promotes comfort and efficient operation for both experienced and inexperienced operators alike. Floor Rear Frame Rubber Comfortable Operator's Seat An air suspension operator's seat is supplied as standard equipment. It displays on-line travel speed, gear position, and other important travel-related information. It also has diagnostic functions. Automatic Transmission Allows Load and Carry Operations Without Shifting Gears This system automatically selects the optimum gear in accordance with the conditions, travel speed, engine speed, etc. The transmission is controlled by the Komatsu Electronic Control Modulation Valve (ECMV) system. The operation is made much easier as the operator no longer has to shift from gear to gear while carrying loads during the work cycle. 10 Multi Monitor On the right of the panel is the color graphic system. Gauges displayed on the monitor include: engine water temperature, oil pressure, fuel level, and payload meter. 11 WA1 200-3 WHEEL LOADER COST-REDUCING COST-REDUCING FEATURES FEATURES Inherent to the Komatsu design are features which help mine operators reduce machine operational costs. Ultra Wide Base Tire Option 65/65-57 62PR ultra wide base tires have been developed exclusively for the WA1200-3. With the reduction of ground pressure, increase of rubber material, and larger air volume, incidents of premature tire wear and tire cutting have been reduced.
