Best practice tyre management saves time and money

Replacing truck tyres is a major expense for quarry operations, so taking practical measures to prolong their useful life makes good sense.
Tony Sambell, the managing director of plant and equipment consultancy Total Equipment Group, says inaccurate loading is a frequent cause of tyre damage.

“With tyres in critical short supply from manufacturers, maximising tyre performance is more important than ever,” Tony says.

He believes that on-board technologies like Loadrite’s scales for loaders can be a major contributor in reducing tyre wear.

“Weighing systems like the L-2180 loader scale from Loadrite provide accurate and consistent weight measurement, so operators can set the correct target weight for the loader bucket and pass match to the vehicle being loaded. So once the wheel loader is set for optimal efficiency, you reduce the potential for tyre damage due to overload.

“Overloading the machine and in turn the tyres will cause tyre tread and ply separation, disintegration of the tyre carcass and inner liner, or radial sidewall cracking.”

Tony notes that under-loading can be problematic, too, as it means more trips than necessary, which in turn equals increased wear on tyres, so accurate weighing is doubly important.

Loadrite loader scales are highly accurate, feature an easy to use interface that many operators are already familiar with, and are cost-effective, generally paying for themselves over a very short period, as they improve mine efficiency almost instantly.

Tony has learned in his two decades of experience in fleet management that regular tyre maintenance and load weight management can increase tyre life on loaders and other earthmoving equipment by as much as 50 per cent. However, it’s critical that the right tyres are selected in the first place.

“Loader and truck tyres are especially prone to damage from protruding rocks. This problem arises in loading areas, on pit floors and haul roads, where truck traffic is concentrated and rocks can cause tyre damage. Spillage is very often the result of overloaded trucks, delivering a double blow to tyre life. Loadrite can help to prevent overloading by ensuring the optimal bucket and truck weights are not exceeded. Further protection can also be provided by good load area maintenance to remove loose rocks and other debris.

“For operations on rocky or loose surfaces, I recommend cut resistant tyres which are manufactured with extra rubber to prevent the damage caused by harsh surfaces. For load and carry operations, heat resistant tyres will prevent the potential damage caused by continuous travel on-site under load which generates substantial heat in the tyre.”

Once the right tyres are selected, Tony says that it is simply a matter of ongoing maintenance and the use of smart systems such as those provided by Loadrite.
