WA320PZ-6 Komatsu WA320PZ-6 Specifications & Technical Data (2009—2016)

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.

Advanced traction control system

The new advanced traction control system lets the driver adjust traction precisely to working conditions. The provided rim pull can be set to 5 different levels to prevent spinning wheels on any ground conditions, even when operating on snow. Constant traction increases productivity and reduces tyre wear and cost.

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 all 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.

Factory fitted automatic lubrication system

The automatic lubrication system reduces the daily service work to the absolute minimum. Robust piping ensures consistent lubrication and operating reliability, and significantly increases the machine’s service life. The system is electronically monitored and features a signal light in the cabin.

Walk-Around

The highly versatile Komatsu WA320PZ-6 wheel loader features a perfect mix of power, comfort and reliability. With the new ecot3 engine and an advanced hydrostatic drive line, it offers exceptional tractive force and ultra-low fuel consumption. This machine sets new efficiency standards for wheel loaders.

Low Consumption Ecot3 Engine

The Komatsu SAA6D107E-1 engine provides high torque, better performance at low speed, and low fuel consumption. This ecot3 engine features a new combustion chamber design with optimised ignition and combustion timing. The operating pressure of the new common rail system was increased for improved injection and fuel efficiency. Additionally, the air-to-air intercooler reduces the temperature of the compressed air supplied by the turbo charger to the cylinders, further improving fuel consumption.

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 the 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.

Meets EU Stage IIIA

The new Komatsu ecot3 engine technology reduces NOx and particle emissions, fuel consumption, and noise level. The Komatsu SAA6D107E-1 is certified for EPA Tier III and EU Stage IIIA emission regulations.

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.

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. They are fully co-ordinated with one another, thus offering 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, ensuring the long service life of the power train and the drive line system.

Wet Multi-Disc Service Brake

The multi-disc service brake is encapsulated and runs in an oil bath. This design keeps the brake clean and allows it to operate at low temperatures, resulting in increased service intervals and a long lifetime.

Engine

The Komatsu SAA6D107E-1 is a turbocharged common rail direct injection diesel engine that is EU Stage IIIA/EPA Tier III compliant. It features a fuel filter with a water separator, an engine cooling fluid corrosion resistor, a 60 A alternator, a 4.5 kW/24 V starter motor, and two 110 Ah/12 V batteries.

PPC-Multifunction lever

The servo-assisted multi-function lever with an integrated forward/reverse switch allows the simplest and most comfortable operation of the equipment. With one hand the driver can simultaneously control the attachment and switch between forward and reverse. As an additional option, the third spool can be controlled by two buttons on the multi-function lever for easy work with a grapple or a high dump bucket.
