During a recent site visit to one of WA’s Pilbara mines, a valued client presented us with an interesting engineering task involved in Komatsu 830E rear strut maintenance.

830E rear strut pins often require lancing where they are burned from the inside out toward the tyre. This action has the potential to shoot the thermal lancing rod out with force, often penetrating the tyre. Not only can this be an expensive issue, it also carries some risk that a person is struck by the lancing rod, potentially causing serious injury.

Following some back and forth discussion, the final solution was presented to our client (pictured to the left).

Our “Lancing Tyre Protection Trolley” is an adjustable height scissor lift trolley fitted with a pivot arm which holds a ceramic plate inside a steel frame.

As you can see in the photo below, the trolley is set to the required height and wheeled into its correct positioning. The plate is then set in place where it can slide in between the rear strut pins and the tyre.

The trolley is constructed in heavy-duty steel and is designed to be easily manoeuvrable by anyone to reach difficult locations.

The ceramic plate blocks the thermal lancing rod from penetrating the tyre and reduces the potential for maintenance personnel being struck by the rod. It also blocks out sparks caused by the lancing. The design suits any haul truck and can be customised to suit your specific requirements.
