Italy – Operating a fully-loaded 120-ton dumper in a slippery, clay quarry is Alfie Jones’ job and every day he moves four-wheel giants in Nanpean, Cornwall, on one of the most important sites of the multinational Imerys. To fit out the dumpers (CAT 775G), the choice fell on the EARTHMAX SR 45 M, in the 24.00 R 35 size.

“We have to move quickly in the quarry on difficult terrain, to load and transport the extracted material. For this reason we need a tire which gives us a sense of safety, with excellent grip, a wide tread, capable of great performance even when fully loaded, without this impacting on the vehicle’s consumption,” said Jones.

EARTHMAX SR 45 M is a radial All Steel tire which has been designed for rigid dumpers which operate on muddy surfaces and is available in three types of compound—normal, heat resistant and cut resistant. A characteristic of this tire is the E-4 depth of the tread which allows constant resistance against the numerous obstacles on sites such as quarries, where conditions are very challenging. The versions with the cut resistant and heat resistant compounds guarantee excellent traction and great resistance also for long-distance transport.

“With a little water the clay-rich terrain becomes very slippery, and that is when we have to rely on the vehicle and the tires. This is the real challenge to be faced when working in this type of quarry,” said Jones.
