Category two – Best solution to an identified work health and safety issue
Komatsu Australia assembles and distributes earthmoving equipment ranging from small 1.8 tonne hydraulic excavators through to 700 tonne excavators and 360 tonne dump trucks.
In order to change equipment track sizes to suit customer requests, staff were manually changing tracks on machines of 4.5 to 5.5 tonne where tracks could weigh between 190 and 290 kilograms.
Komatsu engineered and built the track cradle that uses a frame and forklift to lift, fit and secure equipment tracks.
The cradle has significantly reduced the risk of injury from manual task activities as well as created time efficiencies and significant cost savings. The time to complete a track change has reduced from 12 hours down to four hours, with only one person required for the task (rather than three). Over the build of the last 36 machines, this has saved the company approximately $28,944 in labour costs, and no further injuries have been reported.
