WA900-8R Komatsu WA900-8R Specifications & Technical Data (2022—2026)

High Resolution 7-inch Color LCD Monitor

The machine monitor displays various machine information and allows for various settings of the machine. The monitor is a 7-inch color LCD and displays maintenance information, operation record, ECO guidance record, etc. The switch panel is used to select various screens and the air conditioner control screen. By using the switch panel, you can display various user menus on the LCD screen and adjust the machine settings.

Visual User Menu

Pressing the menu switch on the switch panel displays the user menu screen. The menus are grouped for each function, and use easy-to-understand icons which enable the machine to be operated intuitively.

Machine Monitor with Troubleshooting Function to Minimize Downtime

Various meters, gauges and warning functions are centrally arranged on the machine monitor. The monitor simplifies start-up inspection and promptly warns the operator with a lamp and buzzer if any abnormalities should occur.

Side-opening Engine Doors

Daily maintenance is simplified through large side panels. Large steps are provided on each side of the frame to help access.

Battery Disconnect Switch

The battery disconnect switch is located near the left side battery box. This can be used to disconnect power when performing service work on the machine.

Machine Lock Out System (Optional)

The machine lock out switch is located near the right side battery box. When activating the switch, traveling, steering and work equipment actuation can be locked from outside.

Service Center (Optional)

Replacement and supply of oil, coolant and grease can be done from the ground. Maintenance time can be remarkably shortened.

Fuel Quick Charge System (Optional)

The fuel filler port is located on the left hand side of the machine for easy access from the ground level.

Maintenance Information

When the remaining time to maintenance becomes less than 30 hours, the maintenance time monitor appears. Pressing the menu switch displays the maintenance screen.

High Production Technology and Improved Economy

Overwhelming workability added to environmental performance for the next generation. Komatsu wheel loader WA900 series move to a new stage. Optimum power and loss reduction eliminate useless fuel consumption and improve fuel consumption efficiency.

Low Fuel Consumption

Komatsu installed new features on the WA900-8R to reduce fuel consumption by optimally controlling engine power, realizing high efficiency power train and hydraulic system.

Automatic Transmission

Automatic transmission with Electronic Controlled Modulation Valve automatically selects the proper gear speed based on travel speed, engine speed, and other travel conditions. The Electronic Controlled Modulation Valve system engages the clutch smoothly to prevent lags and shocks when shifting. This system provides efficient machine operation and a comfortable ride.

Komatsu SmartLoader Logic

The WA900-8R provides Komatsu SmartLoader Logic, an engine control system. This technology creates enough torque for each work phase. For example, engine torque needs are higher for digging in V-shape loading, but less when driving with an empty bucket. This system optimizes the engine torque for all applications to minimize fuel consumption. Komatsu SmartLoader Logic functions automatically and doesn’t interfere with operation, saving fuel without decreasing production.

Tire Slip Control System

This system is effective for extending the service life of tires. It senses tire slip with a speed sensor, then controls the torque converter with the modulated clutch.

Komatsu Components

Komatsu manufactures the engine, torque converter, transmission, hydraulic units, electric parts, and even each bolt on this wheel loader. Komatsu loaders are manufactured with an integrated production system under strict quality control system.

Energy Saving Operation ECO Guidance

In order to support optimum operation, the following 5 guidance messages are displayed for fuel saving operation: Excessive engine idling event Hydraulic relief pressure event Dragging of brake event Excessive stepping on accelerator event Excessive digging event. The ECO guidance menu enables the operator to check the operation record, fuel consumption history and ECO guidance record by pushing the button. The records can be used to reduce the overall fuel consumption.

Adjustment-free Braking System

Wet multi-disk service brakes and fully hydraulic braking system mean lower maintenance costs and higher reliability. Wet multi-disc brakes are fully sealed, helping keep contaminants out, reducing wear and maintenance. Brakes are adjustment-free, meaning even lower maintenance. Reliability is designed into the braking system by the use of two independent hydraulic circuits. This provides hydraulic backup should one of the circuits fail. Fully hydraulic brakes mean no air system to bleed, or condensation water in the system that can lead to contamination, corrosion or freezing.

Brake Cooling System

Redesigned brake cooling system integrated with the radiator is standard equipment. Durability and heat dissipation has been improved.

Swing-out Type Cooling Fan and Wide Core Radiator

The cooling fan swings out for cleaning. The coolers feature wide spacing of the cooling fins to reduce clogging.

Operator Environment

Automatic digging systemSemi-auto approach & dump systemNew operator seat with control leversElectronically controlled suspension system (Optional)Power ladder (Optional)

New Operator Seat with Control Levers

A new air suspension seat provides enhanced support on rough roads and dampens machine vibrations, providing a more comfortable ride for the operator. An Electronic Pilot Control lever console and an advanced joystick steering lever is integrated in the seat and moves with the seat. The angle of the armrest is fully adjustable for optimum operator comfort. A heated seat is standard.

Pillar-less Large Cab with ROPS/FOPS

The new design cab with the spacious space is ROPS/FOPS standard for operator's safety. The interior of the cab is improved to provide a quiet, low-vibration, dustproof, and comfortable operating environment. ROPS (ISO 3471) : Roll-over Protective Structure FOPS (ISO 3449) : Falling Objects Protective Structure

Sweeper Wing (Large Size Tire Guard)

Sweeper Wing (Large Size Tire Guard) provided on both sides of bucket prevents damage of tire cut due to rock and prolong tire life.

High-rigidity Frames and Loader Linkage

The front and rear frames and the loader linkage have more torsional rigidity to provide increased resistance to stresses. The frames and loader linkage are designed to accommodate actual working loads, and simulated computer testing proves their strength.

Durable Bucket

Komatsu buckets are manufactured using high-tensile steel with long life. The bottom, corner and side edges of the bucket are strengthened and durable. The bucket spill guard was redesigned into a shape that difficult to spill load while securing the forward visibility during loading operation.

Cutting Edges and Teeth

These teeth tips which are attached to an adapter that is welded or bolted to the bucket edge. This means that an interchangeable part, the tooth tip, absorbs most of the wear and protects the actual bucket edge. They give excellent performance when used to handle blasted rock, piles of earth and similarly heavy duty tasks.
