WA270-8E0 Komatsu WA270-8E0 Specifications & Technical Data (2021—2026)

Easy Maintenance

Easy Maintenance Wide-core radiator with auto reverse fan Improved gull-wing type engine doors Factory fitted automatic lubrication system (option)

Easy control in confined areas

The self braking effect of the HST drive line slows down the machine when the accelerator pedal is released. Uncontrolled rolling is prevented, and safety is greatly improved, especially when working in confined spaces or inside industrial buildings. In addition, brake wear is practically eliminated.

Easy access to service points

For easy and safe opening the gull-wing doors are supported by gas springs. The large doors give a convenient access from ground level to all daily service points. With long service intervals and filters collected in a centralised arrangement, machine downtime is reduced to a minimum.

Wide-core radiator with auto reverse fan

A wide-core radiator prevents clogging even when working in a dusty environment. To minimize manual cleaning, a reversible fan blows dust out, automatically or on demand. The “automatic reverse” function allows to set the cleaning length and the time between cleaning to adjust perfectly to the working conditions.

AdBlue tank

The AdBlue tank is located on the right hand side of the machine behind a ladder for easy access.

Diesel particulate filter regeneration

No interruption or extension of daily work is required to regenerate the diesel particulate filter system. Due to its superior Komatsu technology, KDPF regeneration takes place automatically, at any time.

Wet multi-disc service brake

The multi-disc service brake is encapsulated and runs in an oil bath. The brake stays clean and operates at low temperature for increased service intervals and a long lifetime.

Increased Fuel Efficiency and Environmental Performance

Powerful and Environmentally Friendly EU Stage V engine Komatsu SmartLoader Logic Highly efficient hydrostatic drive line High efficiency buckets Adjustable idle shutdown

Responsive Hydrostatic Drive Line (HST)

The Komatsu HST drive line features exceptional responsiveness that results in quick acceleration and fast forward/reverse changes. The drive line reacts to the operator’s command without any time lag and instantly provides torque at the wheels. This allows for fast loading cycles and higher productivity. Instant response for fast loading cycles Easy control in confined areas Advanced traction control system for best traction and minimized tyre wear (K-TCS) Top speed selection for increased safety

Highly efficient hydrostatic drive line

The electronically controlled variable pump and 2-motor system allow highly efficient and powerful operation. At low speeds both motors are engaged to provide highest torque. Bucket filling and scooping are easy, as maximum rim pull is provided from zero travel speed. At high speeds, a clutch cuts off the low speed motor to eliminate drag and achieve excellent fuel efficiency.

Komatsu SmartLoader Logic

The WA270-8 provides Komatsu SmartLoader Logic, a fully automatic engine control system. Without interfering with normal operations, this technology acquires data from various sensors in the vehicle and delivers optimal engine torque for each work phase. It limits torque during less demanding operations and reduces fuel usage without decreasing production.

Advanced traction control system (K-TCS)

The Komatsu Traction Control System (K-TCS) controls the HST pump, motor and engine to optimize traction automatically depending on work conditions. The provided rim pull can be set to 6 different levels to prevent spinning wheels on any ground conditions, even when operating on snow (S-mode). Constant traction increases productivity and reduces tyre wear and cost.

PPC multi-function lever

The PPC multi-function lever with electronic control for 3rd spool (EPC) is standard. It includes a forward-neutral-reverse switch for quick and easy travel. Third spool attachments can be set to continuous or proportional control via the monitor panel, to let the operator control the boom, bucket and attachment with a single lever.

Designed and built by Komatsu

The engine, hydraulics, power train, front and rear axles are original Komatsu components. All these components are subject to the highest quality standards right down to the smallest screw. All components are fully co-ordinated with one another, thus offering the maximum efficiency and reliability.

HST drive line with overrun protection

The hydrostatic drive line is equipped with an overrun protection that electronically limits the top speed when driving downhill and thus ensures the long service life of the power train and the drive line system.

More fuel-saving technology

The WA270-8’s Eco-gauge displays active recommendations on the cab’s monitor to help you maximise those fuel savings. For added fuel economy, and to prevent wasted hydraulic flow when working or steering, the hydraulic system’s new variable piston pump delivers the exact amount of oil required for all machine movements.

First-Class Comfort

First-Class Comfort New, air-suspended operator seat Large multifunctional monitor Low-noise design Rear-view camera system Komatsu short lever steering (K-SLS) (option)

New, fully air-suspended operator seat

The wide spacious cab features a new, fully air-suspended operator seat with a high back, fully adjustable, standard heated seat for improved comfort. A seat ventilation is optionally available to maximise comfort.

Improved operator convenience

With increased in-cab storage space, an auxiliary input (MP3 jack) and 12 V and 24 V power supply, the cab offers maximum convenience. The automatic air conditioner allows the operator to easily and precisely set the cab’s atmosphere.

Rear view camera

A standard fitment camera gives an exceptionally clear view of the rear work zone on the wide-screen colour monitor panel. The low profile camera is adjustable and integrated into the engine hood’s shape.

Komatsu short lever steering (K-SLS) (option)

The new finger-type joystick steering allows more accurate steering by the operator who can now sit relaxed in the new air-suspended and fully adjustable seat to control the machine with no big effort needed for frequent steering. Less fatigue and work in a perfectly adapted operating position will improve concentration and the quality and efficiency of the work.

Cabin

PZ-Linkage

PZ-Linkage Combines advantages of Z-bar linkage with parallel lift Fast pallet handling Excellent break-out force and easy bucket fill High tilt forces give perfect control of heavy attachments

One machine for all applications

The PZ = “parallel Z-bar” has the added advantage of parallel lift for pallet moving and high tilt forces to handle large attachments. The PZ-linkage turns your WA270-8 into a true multipurpose machine ready to take on any job.

Parallel lift for fast pallet handling

With the parallel lift PZ-linkage, pallet moving becomes easy. The parallelism has been optimized for safe work over the entire lifting range. The excellent visibility of the front attachment allows an easy pick-up of pallets and precise work when loading onto trucks.

Easy bucket fill

The superior break-out force of the WA270-8 turns loading into a child’s play, even for an untrained operator. More experienced workers will also appreciate this feature, particularly when working with high density material such as heavy soil or aggregate.

Controlled work with heavy attachments

With the PZ-linkage design, tilting forces reach an optimal level, especially at maximum boom height. This is essential for controlling large attachments such as high dump buckets or other oversized buckets. The WA270-8 is the ideal choice when working with heavy attachments.

Waste handling

We adapt our wheel loaders to the different conditions that exist on waste handling job sites. Along with heavy duty attachments, we offer solutions to protect your machine against damage.

Agriculture

Simple handling, reliability and comprehensive safety features make Komatsu “agriculture” wheel loaders the ideal tools for contractors or large farms, for loading or for material handling. They are fitted with robust protection and safety equipment to provide perfect protection for both operator and machine.

Heavy-duty axles

The heavy-duty axles allow exceptional service life even under the toughest working conditions. As standard, the WA270-8 is equipped with torque proportional differentials for work on good ground conditions such as on concrete yards or roads. The optional limited slip differentials are most suitable for soft and slippery ground like sand or wet soil.

High efficiency bucket range

The Komatsu high efficiency buckets enable easier bucket fill and significantly higher fill factors, contributing to more efficiency and less fuel consumption. They feature a longer bottom for more bucket content, a wider opening for an easier fill and a new rear shape that enables material to flow easily into the bucket. Their rounded sides give them a higher fill factor, and an integrated spill guard protects the bucket linkage.

High efficiency flat bottom buckets

The flat bottom bucket is used for soft grounds applications that require occasional grading passes, easily performed with the bucket’s rear edge. This one-piece bottom bucket type is also suitable for earthmoving applications and for loading adhesive material.

High efficiency raised bottom buckets

The raised bottom bucket is suitable for hard surfaces applications with a high digging ratio. It excels with its outstanding penetration and breakout performance, together with good material retention. The combination of a rounded back side and convex side walls results in high bucket fill factors and minimal spillage during material transport.
