Sailun Group has received letter of acceptance from China Shenhua International Engineering Co., Ltd. recently and becomes the winner of MT5500 Mining Truck 59/80R63 Tire Development and Application project, which is the world’s biggest tire currently.MT5500 mining truck is the mining truck with the largest loading capacity in the world currently. The empty truck is more than 200t and full-loaded truck is about 500t. Extremely heavy load requires higher technical standards of tire in anti-cutting, abrasion resisting, collision resisting, thermal capacity and high TKPH.The tire adopts stress-reducing principle in its contour design of heavy load CASE LINE, optimizing its body curve to enhance its bulging performance of tire bead. Shape of new tire adopts the best stress control technology to balance pressure distribution of bottom of traveler and reduce the possibility of delamination of tire bead. It also uses new steel grid structure design to enhance strength of the tire to cope up with overloading and collision with stone.
