HIGHLIGHTS

KOMATSU WA600-6R - HIGH PRODUCTIVITY AND LOW FUEL CONSUMPTION

High Performance SAA6D170E-5 Engine

Electronic Heavy Duty Common Rail fuel injection system provides optimum combustion of fuel. This system also provides fast throttle response to match the machine’s powerful tractive effort and fast hydraulic response. This engine is EPA Tier 2 and EU Stage 2 emissions equivalent. Net: 393 kW 527 HP

Low Fuel Consumption

The fuel consumption is reduced greatly because of the low-noise, high-torque engine and the large-capacity torque converter with maximum efficiency in the low-speed range.

Dual-mode Engine Power Select System

This wheel loader offers two selectable operating modes E and P. The operator can adjust the machine’s performance with the selection switch.

- E Mode: This mode provides maximum fuel efficiency for general loading.

- P Mode: This mode provides maximum power output for hard digging operation or hill climb.

Automatic Transmission with Mode Select System

This operator controlled system allows the operator to select manual shifting or two levels of automatic shifting (low, and high). Auto L mode is for fuel saving operation with the gear shift timing set at lower speeds than Auto H mode. Therefore Auto L mode keeps the engine in a relatively low rpm range for fuel conservation while yielding adequate tractive force by depressing the accelerator pedal.

Lock-up Torque Converter

The Komatsu designed lock-up torque converter provides increased production efficiency, reduced cycle times and optimum fuel savings in load & carry or hill-climb operations. This optional feature allows the operator to activate the system on/off with a switch located on the right-side control panel.

Variable Displacement Piston Pump & CLSS

New design variable displacement piston pump combined with the Closed-center Load Sensing System delivers hydraulic flow just as the job requires preventing wasted hydraulic pressure. Minimized waste loss contributes to better fuel economy.

- New Variable Displacement Piston Pump: The pump delivers only necessary amounts minimizing waste loss.

- Fixed Displacement Piston Pump: The pump delivers the maximum amount at any time and the unused flow is disposed.

Increased Bucket Capacity Matches with One Class Higher Dump Truck

Komatsu WA600 can load 60t (70 Short ton) trucks with standard boom. The WA600-3 required an optional high lift boom and 6.4m3 bucket. WA600-6 wheel loader maintains good visibility for loading because of increased operator cab height.

- Dumping Clearance: 3995 mm.

- Dumping Reach: 1800 mm (6.4 m3 8.4 yd3 spade nose bucket with tooth)

Long Wheelbase/Articulation Angle of 43˚

The widest tread in class and the long wheelbase provide improved machine stability in both longitudinal and lateral directions. Since the articulation angle is 43˚, the operator can work efficiently even in the tightest job sites.

- Tread 2650 mm.

- Wheelbase 4500 mm.

- Minimum turning radius 7075 mm (center of outside tire)

KOMATSU WA600-6R - INCREASED RELIABILITY

Komatsu Components

Komatsu manufactures the engine, torque converter, transmission, hydraulic units, electric parts, on Komatsu WA600-6R wheel loader. Komatsu loaders are manufactured with an integrated production system under a strict quality control system.

Wet Multi-disc Brakes and Fully Hydraulic Braking

System mean lower maintenance costs and higher reliability. Wet disc brakes are fully sealed. Contaminants are kept out, reducing wear and maintenance. Brakes require no adjustments for wear, meaning even lower maintenance. The new parking brake is also an adjustment-free, wet multi-disc for high reliability and long life. Added reliability is designed into the braking system by the use of two independent hydraulic circuits. Provides hydraulic backup should one of the circuits fail. Fully hydraulic brakes mean no air system to bleed, or the condensation of water in the system that can lead to contamination, corrosion, and freezing.

High-rigidity Frames and Loader Linkage

The front and rear frames and the loader linkage have more torsional rigidity to secure resistance against increased stress due to the use of a larger bucket. Frame and loader linkage are designed to accommodate actual working loads, and simulated computer testing proves its strength.

Flat Face-to-face O-ring Seals

Flat face-to-face O-ring seals are used to securely seal hydraulic hose connections and to prevent oil leakage. In addition, buffer rings are installed to the head side of the all-hydraulic cylinders to lower the load on the rod seals and maximize the reliability

Cation Electrodeposition Primer Paint/ Powder Coating Final Paint

Cation electrodeposition paint is applied as a primer paint and powder coating is applied as topcoat to the exterior sheet metal parts. This process results in a beautiful rust-free machine, even in the most severe
environments. Some external parts are made of plastic providing long life and high impact resistance.

Sealed DT Connectors

Main harnesses and controller connectors are equipped with sealed DT connectors providing high reliability, water resistance and dust resistance.

Sweeper Wing (Large Size Tire Guard)

To prevent tire damage, Komatsu WA600 provides a Sweeper Wing (Large size Tire Guard) on both sides of bucket.

EASY MAINTENANCE

With long service intervals and best-in-class accessibility, Komatsu WA600-6R reduces the time and money you need to suspend on maintenance. A gas spring helps the operator open and close each gull-wing side door for easy daily servicing.

Easy Radiator Cleaning

Reversible hydraulic fan

A push-button switch in the cab allows the operator to run the radiator fan in reverse for working in dusty environments.

Swing out fan

The hinged, bolt-on fan can be swung out for easier cleaning. The coolers feature wider spacing of the cooling fins to reduce clogging.

Simple fluid level checks

All important fl uid levels can be easily checked from ground level. Sight gauges for coolant, oil and air cleaner let you check the level at a glance.

Modular radiator core system

The modular radiator core is easy to replace without removing the entire radiator assembly.

Equipment Management Monitoring System

Monitor is mounted in front of the operator for easy viewing, allowing the operator to easily check gauges and warning lights. A specially designed two-spoke steering wheel allows the operator to easily see the instrument panel. Maintenance Control and Troubleshooting Functions
