Understanding loading stress in tracks

article image Track snapping is caused by continual unloading and loading of equipment
Camoplast construction rubber tracks available in Australia from Bearcat Tyres are manufactured using premium quality materials and designed for high durability.

But constant loading and unloading of the loader during transportation can cause damage to its tracks. Most track stress incidents happen before the machine actually hits the job site. Track breakage is a common occurrence but is preceded by a history of stress factors.

Mini excavators, compact track loaders and multi terrain loaders are typically transported using prime movers with tipping bodies, and the machines are loaded or unloaded using metal ramps creating a number of issues due to the height of the body creating a greater incline.

The step transition from truck-to-ramp and ramp-to-ground causes a high level of strain on the track construction. The main area of damage is the pivot point at the ramp-to-truck area in which the machine ‘rocks’ and then ‘drops’. Continuous unloading and loading of equipment cause a fracture or create a stress point in the track leading to track damage. 

Track damage is also caused by aggressive rungs on the ramps, which leads to grabbing of tread lugs, resulting in severe torque on the lugs.

Minimising the degree of slope while loading or unloading the equipment can help reduce damage to the tracks. A low deck trailer with long, low impact ramps is recommended to create a smoother transition.

Bearcat Tyres  is the Australian division of the Camoplast Solideal Inc. group of companies with five branches across Australia.
