HOWHAUL ROAD MAINTENANCE CAN EXTEND TYRE LIFE

Traditionally, tyres were just a cost of doing business. Mine and quarry owners were accustomed to spending the initial purchase price of a large mining truck in tyre-related costs over the lifetime of the machine. Today, tyres are no longer considered just a cost; they are mission- critical to keeping your haulage fleet working.

AVOID TANKING RISKS Successful aggregate managers know multiple factors contribute to their profitability, from minimising their trucks’ cycle times to ensuring their crew’s safety. Even support equipment, such as water trucks, can’t escape their analysis – or at least they shouldn’t.
