Maintenance Methods for Tires of Mining Dump Trucks
Mining dump trucks are widely used in industrial and other relevant sectors. They can effectively reduce time costs. Tires are a crucial component of mining dump trucks. To ensure their reliable operation, proper maintenance is essential. So how should we maintain them? Below is a detailed guide shared by the editorial team from a mining underground transport vehicle manufacturer.
The utility – modified vehicle is similar to a tractor. Most of its key components, including the steering wheel, chassis and front – rear axles, are disassembled from scrapped vehicles and other miscellaneous parts. Equipped with a high – power diesel engine, it has a large loading capacity. This type of vehicle is mainly suitable for use in geographical environments such as mountainous areas, rural areas, towns and county seats.
A new tire will degrade if stored for more than four years. This is because rubber is the main material of tires, and a key characteristic of rubber is that it deteriorates over extended periods of time. Using aging tires will impair vehicle performance and even threaten lives. Therefore, tires that exceed their service life must be replaced.
When a mining dump truck is negotiating turns, the driver shall operate it in accordance with the curve conditions, turning radius, traffic density and vehicle speed. Generally, the driver must appropriately reduce the speed and avoid cornering at high speed. This prevents unilateral tire overloading and dragging caused by inertia and centrifugal force, which could accelerate tire wear and even lead to rollover accidents.
When the utility – modified transport vehicle is climbing slopes, the driver should try to make use of inertia to move forward, shift gears timely and appropriately. It is essential to keep the vehicle with sufficient reserve power while ascending. Never restart the vehicle after it comes to a complete stop, as this helps reduce tire wear. When descending long slopes, the driver shall properly control the vehicle speed according to the slope gradient, length and road conditions.
Tires provide support for mining dump trucks to make contact with the ground and ensure their driving performance. However, as mining dump trucks are used under complex and harsh conditions for a long time, their tires are subjected to various challenges such as deformation and loads, resulting in severe wear. To extend the service life of tires on utility-modified vehicles, it is necessary to implement appropriate maintenance measures.
