WA1200-6 Komatsu WA1200-6 Specifications & Technical Data (2020—2026)

Easy Maintenance

Tire saver Long oil replacement interval Oil sealed loader linkage pins Centralized filter layout Quick fluid change-out system Auto-greasing system EMMS (Equipment Management Monitoring System) KOMTRAX Plus Maintenance accessibility Safety features Rear access stairs.

Tire Saver

The tire saver is quite effective for extending the service life of tires. It senses the tire that slips with a speed sensor, then controls the torque converter with the modulated clutch and stops the tire slip.

Long Oil Replacement Interval

Adoption of hybrid elements, that catch the fine and coarse contamination, has extended the interval between replacing elements.

Rear Access Stairs

For safely boarding and exiting the machine, rear access stairs with a safety handrail are provided. The step width, clearance and angle have been designed for safety. The step angle has been reduced from 60 to 45 degrees. A step light provides light for night boarding. The emergency ladder is on the right side of the machine.

High Productivity & Low Fuel Consumption

High performance SSDA16V160E-2 engine Low fuel consumption The largest bucket in its class Extra dumping clearance and reach Hi-cab Remote boom positioner Selectable traction power.

High Performance SSDA16V160E-2 Engine

Economical Komatsu SSDA16V160E-2 diesel engine provides power with reserve margins to move giant 20.0 m³ 26.2 yd³ loads. Equipped with an electronic governor for low fuel consumption and electronic acceleration pedal and rpm set for easy operation.

Low Fuel Consumption

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

Remote Boom Positioner

The highest and lowest position of the bucket can be set from the operator's seat to match the height of any truck body. Where the positioner is set will stop the bucket smoothly without shock.

Selectable Traction Power and Travel Speed

Maximum traction control: Traction can be set at any level within 20 - 100% with the „TRACTION CONTROL DIAL“ located on the left front. You can set the maximum traction force according to the condition of the road, material and type of work. It greatly increases fuel efficiency and extends the service life of tires. Maximum speed control: With the „VEHICLE SPEED DIAL“, you can set the maximum vehicle speed of 1st. and 2nd. at any level from 3km/h to max. This means the operator can set the cycle time between the material and the dump truck. As the loading cycle time is shortened, productivity is improved.

Modulated Clutch System

When approaching the dump truck, the current system requires the engine rpm to be increased to raise the bucket faster. Now, the modulated clutch is controlled automatically to raise the bucket faster, while reducing forward travel speed. This reduction in travel speed eliminates the braking requirement and the time to approach the dump truck is shortened. This combination also reduces torque waste and smooths the operation.

E↔P Control of Engine

The engine output function has „2 mode“ of Economy or Power. They are selected and controlled automatically. P mode is selected only when digging and approaching the dump truck. This „2 mode“ engine control contributes not only to the reduction of the fuel rate but also to the improvement of reliability and durability.

Easy Operation

Automatic transmission with ECMV automatically selects the proper gear speed based on travel speed, engine speed, and other travel conditions. The ECMV engages the clutch smoothly to help prevent lag and shock when shifting. This system provides efficient machine operation for a comfortable ride.

Engine RPM Set System with Auto Decel

Engine Low idle RPM can be easily preset using a push button switch. The system provides auto decel for better fuel consumption.

Variable Transmission Cut-off System

Transmission cut-off position of the left brake pedal is optionally adjustable by switch operation at operator’s seat. By adjusting the cut-off position according to the type of work, the inching operation becomes easy and increases efficiency. When loading, adjust the cut-off pressure to low. Then the impact of braking is low to prevent spillage. When traveling, adjust the cut-off pressure to high. Load applied to brake will be lighter by using engine brake while decelerating.

Dual-mode Active Working System

This system provides the most efficient hydraulic flow for your operation. The active working switch has two modes: powerful loading or normal loading.

PNC (Pump Neutral Cut) Control System for Hydraulic Pump

The variable displacement piston pump combined with the PNC (Pump Neutral Cut) system, use only the required amount of oil flow for the work, so it does not waste oil pressure. This function reduces the fuel rate by controlling the pump discharge, when not operating the work equipment.

Variable Displacement Steering Pump + CLSS

The variable displacement steering pump, combined with the Closed-center Load Sensing System, delivers just the hydraulic flow the steering requires. This prevents wasted hydraulic pressure and contributes to increased fuel economy.

Excellent Operator Environment

Automatic transmission with ECMV (Electronically Controlled Modulation Valve) AJSS (Advanced Joystick Steering System) Engine RPM set system with auto decel Variable transmission cut-off system Roomy, quiet cab with power windows Low vibration & noise Pillar-less large cab with ROPS/FOPS canopy Comfortable operator’s seat Trainer seat (optional)

Comfortable Operator's Seat

The operator's seat has a reclining/air suspension design with headrest to support the operator comfortably during long operation. Also, it is easy to adjust seat height with air suspension.

Comfortable Operation

The cab is large, with a comfortably spacious interior and power windows. Also, a wide viewing angle is guaranteed because the cab is pillar-less. By adopting a high-capacity air conditioner, Komatsu ensures operator comfort, no matter the exterior conditions. Other features designed with operators in mind include a lunchbox storage space.

Overhead Panel

Controls for the AM/FM radio, window wiper and washer, cab lights, and air conditioner are all neatly arranged in an overhead console easily within the seated operator’s reach.

Pillar-less Large Cab with ROPS / FOPS Canopy

A wide pillar-less flat glass provides excellent front visibility. The wiper arm covers a large area to provide great visibility even on rainy days.

Cab Air Conditioning

Large capacity air conditioning system combined with carefully placed vents provide optimum cool air flow. Defroster vents are designed to keep the rear window frost-free during cold weather operation. With a simple touch of his hand the operator can easily select from the five operating modes and four fan speeds on the overhead control panel.

EMMS (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.

The Largest Bucket in Its Class

The WA1200-6 is equipped with the largest bucket in its class at 20.0 m³ 26.2 yd³. Komatsu's bucket is designed for easy loading with little spillage. This, combined with the highest traction and breakout force available, makes a loader which achieves high bucket fill factors and maximum production, able to outproduce other loaders.

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, 6380 mm 20'11" from the ground, the seated operator has a safe, unobstructed full view of the bucket and the inside of a 220-tonne truck body.

Matching with Dump Trucks

Aggressive loading and maximum fill factors lead to exceptional productivity in the toughest mining conditions. The WA1200-6 equipped with a 20.0 m³ 26.2 yd³ bucket can load a 140-tonne truck in four passes. Due to its extra dumping clearance and reach it is able to load 180-tonne trucks in five passes. The high lift version can load 290-tonne plus trucks.

High Breakout Force / Traction Force

Komatsu wheel loaders have high-tensile steel Z-bar loader linkages for maximum rigidity and maximum breakout force. Sealed loader linkage pins extend greasing intervals.
