Komatsu has unveiled the WA900-8R mining loader which features obstacle detection and automation technology for safer operations.

The WA900-8R is designed to provide an ease of operation while enhancing productivity and cutting operational costs.

The new loader replaces the Komatsu WA900-3E0 and features Komatsu’s Komvision obstacle detection system.

Komvision uses radar and 360-degree cameras to alert and prompt the loader operator if a person or obstacle is detected.

This has been designed to prevent any serious accidents from occurring around the machine.

A key feature of the WA900-8R Is its SmartLoader Logic technology which delivers the right amount of torque to the engine depending on the duty cycle.

Komatsu national product manager Mark Summerville said the feature can boost fuel economy by up to 10 per cent when compared to the previous model.

“This system functions automatically and doesn’t interfere with operation, saving fuel without decreasing production,” he said.

According to Summerville, the mining loader has an electronically controlled modulation valve that automatically selects the correct gear speed based on travel and engine speeds.

“This ECM valve system also engages the clutch smoothly to prevent lags and shocks when shifting, for more efficient machine operation and a more comfortable ride,” he said.

The loader is powered by a SAA12V140E-7 engine rated at 671 kilowatts and also features automatic dig and semi-automatic approach and dump system.

Komatsu has designed the loader’s hydraulics with closed-centre load sensing system (CLSS) technology to enhance its fuel economy.

“This uses a variable displacement piston pump combined with CLSS to deliver hydraulic flow exactly when the task requires it, preventing wasted hydraulic flow, which further contributes to better fuel economy,” Summerville said.

The loader’s operator environment is improved by the addition of a trainer seat, shockless stop cylinders, climate control air conditioning and modulated clutch.

“Our new automatic digging system actuates the bucket tilt and lifting operations by detecting the sensing pressure applied to the work equipment,” Summerville said.
