Tire selection for small mining trucks
- May 03, 2017 -

In recent years, with the continuous improvement of the degree of mechanization of mining industry in China, the total installed capacity of mine transportation is growing at an average annual rate of 20% to 30%. The demand for transportation equipment, especially mine truck, is increasing. Different types of mining enterprises have different requirements for transportation equipment. Super large mines in the purchase of mine cars are more inclined to choose 170t, 220t, 320t and other large mining trucks, and small and medium sized mining enterprises on the loading of about 30t of small non road dump trucks favor. Especially small and medium sized non highway dump truck, in recent years the pace of development is caused by many manufacturers attention, because this kind of mine car has the characteristics of good flexibility, flexible transportation, especially suitable for small scale mines, and the rapid development of mine enterprises. Many manufacturers also seize the market segmentation operation models, dump truck for open pit mines, ports, water conservancy and Hydropower Engineering and steel construction site operation of the rapid development of small and medium-sized non highway transportation, the market booming.

The changes in the pattern of the market has also given the relevant industries to bring the opportunity, especially to the tire industry. And in general use of earthworks in the dump truck compared to mine truck tires, the car in the mountain wide and ordinary truck are far different from that of mine truck tire requirements more wide, because in poor road conditions, the tire width, stability is good, the bearing capacity is stronger. In addition, the steel used in the mine dump truck is also different from the common dump truck. The tire has a great impact on the later use of the mining dump truck, it is understood that the cost of mining truck tires accounted for 20% ~ ~ ~ of the total cost of the operation

Therefore, how to select the tire with excellent quality, how to strengthen the management of the tire, improve the level of the tire, and put forward higher requirements to reduce the total cost of the mine dump truck. Especially small mine truck tire use environment is relatively poor, work for pavement macadam pavement, many potholes, tire wear faster, service life is not high, and susceptible to puncture and scratching. There is no doubt that this will increase the mine

The cost of the use of mine cards. In view of this situation, the United Kingdom and the United Kingdom has developed a dedicated ETOT series of small mining truck tires, including 11.00R20, 12.00R20 and 12.00R24.

Compared with traditional bias tire. A tread is good abrasion resistance, long service life; the two is the rolling resistance, save fuel; third, high elasticity and good buffering; fourth, anti cutting, anti puncture and tear ability; fifth, large, high attachment surface traction. Compared with similar radial tyres, ETOT series tires with 4 layers of bold wire protection, anti piercing; deepen the pattern, with the surging driving force, is not easy to slip; Techking balance pattern design outline design, special rubber formulation, mine deepen, provide a stable grip at the same time, but also prolongs the service life of the tire.
