KOMATSU WA500-6R - HIGH PRODUCTIVITY AND LOW FUEL CONSUMPTION

Precision Control with Closed-center Load Sensing System (CLSS) Hydraulics

Komatsu WA500-6 wheel loader features variable-displacement pumps on both the hydraulic and steering systems. These pumps deliver the exact amount of oil required, dramatically improving fuel efficiency. Komatsu’s Closed-center load sensing system (CLSS) hydraulics enables extremely precise control of the working gear, and ensures that the bucket, boom and hydraulically driven attachments can all move smoothly at the same time.

Faster Travel & Lower Fuel Consumption

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.

Advanced Power Train

The newly designed Komatsu power train features a large capacity torque converter for maximum efficiency and unparalleled rimpull to weight ratio. The outstanding rimpull at low speeds makes child’s play of heavy job like penetrating blasted rock. This ensures higher productivity in V-shaped loading - even in confi ned spaces. With plenty of acceleration and high travel speeds (even on inclines and steep ramps), Komatsu WA500-6R delivers great productivity and value in load & carry operations. Together, the enhanced engine torque and high-capacity torque converter put WA500-6R loader at the top of its class.

Lock-up Torque Converter (optional)

The Komatsu designed lock-up torque converter provides increased production effi ciency, 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.

Maximum Dumping Clearance and Reach

Komatsu WA500 enables loading onto 32 t (40 Short ton) with the standard spec whereas WA500-6R necessitates the high lift boom with the 4.5 m3 bucket for it. Operator can get good visibility because of high his eye point.

Long Wheelbase/Articulation Angle of 40˚

The widest tread in class and the long wheelbase provide improved machine stability in both longitudinal and lateral directions. Since the articulation angle is 40˚, the operator can work efficiently even in the tightest job sites.

- Tread: 2400 mm.

- Wheelbase: 3780 mm

- Minimum turning radius (center of outside tire): 6430 mm

WA500-6R - INCREASED RELIABILITY

Komatsu Designed Components

WA500-6R’s Komatsu SAA6D140E-5 engine features higher torque, better performance at low speed, excellent throttle response and advanced electronics.

High Pressure Common Rail (HPCR) fuel injection system

A high pressure pump pumps fuel into “Common Rail”. An Electronic Control Unit (ECU) then optimizes fuel injection from the common rail into the engine cylinders. This improves engine power and fuel efficiency, reducing noise levels.

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.

Wet Multiple-disc Brakes and Fully Hydraulic Braking System

Fully sealed wet multiple-disc brakes exert great performance even in the puddles and on soft ground. Added reliability is designed into the two independent braking system with the fully hydraulic circuits. Provides hydraulic backup should one of the circuit fail. There is neither air system to bleed, nor the condensation of water in the system that can lead to contamination, corrosion and freezing.

Reliable Hydraulic Line

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.

Buffer rings

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.

Sealed Connectors

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

KOMATSU WA500-6R - EXCELLENT OPERATOR ENVIRONMENT

The largest in its class, the space cab offers exceptional driver’s comfort - comparable to a passenger car. The large, frameless window gives an unobstructed view of the bucket and tires while the slanted rear end ensures a clear view to the rear. The low-noise designed cab with the air-cushioned seat and the fully adjustable console inside allow the operator to work comfortably and productively over long period.

Pillar-less Large Cab

A wide pillar-less fl at glass provides excellent front visibility. The wiper arm covers a large area to provide great visibility even on rainy days. The cab area is the largest in its class providing maximum space for the operator. Increased seat slide adjustment to backward by introducing front mounted air conditioner unit.

Low-noise Design

The large cab is mounted with Komatsu’s unique ROPS/ FOPS (ISO 3471/ISO 3449) 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, dustproof with pressurizing, and comfortable operating environment.

Best Position for Comfort

Telescopic/Tilt steering column

The operator can tilt and telescope the steering column to provide a comfortable working position

Ergonomic hydraulic controls and large armrest

The Electronic Pilot Control (EPC) levers offer precise, fatigue-free control of the loading process. The height of and distance to the sliding console and the large armrest can be adjusted for maximum comfort

Automatic Transmission

Automatic transmission with Electronic Controlled Modulation Valve selects automatically the proper gear speed based on travel speed, engine speed and other travel condition. The Electronic Controlled Modulation Valve system engages the clutch smoothly to prevent lags and shocks when shifting, allowing the operator to be released from gear shift operation itself.

Hold switch

Auto shift is selected and if the operator turns on this switch when the lever is at the 3rd or 4th gear speed position, the transmission is fi xed to that gear speed.

Kick-down switch

The kick-down switch downshifts to a lower gear when the operator pushes the switch. Gear position is automatically reset when putting the gear into reverse.

One push power-up

The kick-down switch allows to increase power temporally in E mode. In the 1st gear with E mode, pressing the kick-down switch changes the mode to P mode. Useful for heavy digging operation during light application such as Load & Carry operation.

Variable transmission cut-off

The operator can adjust the transmission cut-off connected to the left brake pedal with the switch near the operator’s seat to set the brake/cut-off point for easier operation and higher operating performance in variable operating conditions.

Easy & Simple Operation

Remote boom positioner

The highest and lowest position of the bucket can be set from cab to match any truck body. Once the positioner is set, the bucket is smoothly stopped at desired position with no shock.

Remote bucket digging angle control

The bucket return-to-dig angle can be adjusted by up to 5 degrees in either direction to suit the ground condition.

Automatic boom & bucket kick-out

The kick-out positions can be adjusted from the operator’s seat, stopping lifting and lowing actions smoothly at the desired point so the operator can focus on the job at hand.

Option

Joystick steering

A joystick steering system is available as option equipment, and ensures that steering can be wrist operated easily and conveniently in loading operations. This system allows you to change the direction of travel and gear shifting with push buttons on the joystick. And you may pre-select the steering speed in 2 stages, depending upon whether fast V-loading or precise Load & Carry is required.

Electronically Controlled Suspension System (ECSS)

Electronically Controlled Suspension System uses an accumulator which absorbs some of the shock in the boom arm, giving the operator a much smoother ride. This reduces operator fatigue and reduces material spillage during load and carry operations. Electronically Controlled Suspension System operation is speed sensitive and turned off automatically below 5 km/h speed, meaning that the boom won’t move during stationary digging.
