In summer, with high temperatures, crane tires need "special care"!

Tires are an important component of cranes. The wear and tear of tires during use is also the most significant factor affecting the service life of cranes. Therefore, analyzing the causes of abnormal tire wear and taking corresponding countermeasures are of great significance for extending the service life of cranes, saving costs, improving their utilization efficiency and ensuring safe operation. Today, we will mainly talk about the precautions for the use of crane tires.

For cranes, the first step is to strictly adhere to the tire inflation standards. After inflation, check whether each ministry is leaking air and regularly check the tire pressure to ensure it meets the standards. Form the habit of measuring air pressure with a barometer and do not judge it with the naked eye. Ensure that the tires have a certain degree of elasticity, so that when they are subjected to the specified load, their deformation does not exceed the prescribed range, and guarantee that the vehicle has good stability and comfort during driving. The spare tire should be inflated relatively high to prevent it from running off over time.

Secondly, it is necessary to correctly select and install tires, and use the corresponding inner tubes according to the tire specifications. Tires assembled on the same machinery should ensure the same brand, the same structure and the same performance. If this cannot be achieved, tires of the same brand, specification, pattern and type should be installed on the same axle. When replacing new tires, it is necessary to replace the entire vehicle or the same type of tires at the same time. Directional tread tires should be installed in accordance with the specified rolling direction. When changing to new tires, the new tires should be installed on the front wheels and the repaired tires on the rear wheels. To ensure driving safety, retreaded tires are not allowed to be used as steering wheels.

In addition, it is necessary to regularly rotate the tires of the crane. After a vehicle has been driven for a period of time, the front and rear tires show different degrees of fatigue and wear. Therefore, they should be swapped in a timely manner as per regulations. There are two methods for changing tires: the cross method and the cycle method. The cross-transposition method is suitable for vehicles that frequently travel on roads with a large arch, while the cyclic transposition method is suitable for vehicles that frequently travel on flatter roads.

Finally, the most important thing is to control the temperature of the crane's tires. During the vehicle's operation, the tires generate heat due to friction and deformation, causing the temperature and air pressure inside the tires to rise. When the tire temperature is very high, the method of deflating to reduce pressure should not be adopted, and even less should water be poured on the tire to cool it down, as this may accelerate the damage to the tire. You should park and rest in a shady place. Do not continue driving until the tire temperature drops. When vehicles stop during the journey or arrive at the scene, it is necessary to develop the habit of parking safely by coasting. Choose a flat, clean and oil-free ground for parking, and ensure that each tire touches the ground smoothly. When a vehicle is out of use for a long time, wooden blocks should be used to prop up the frame to reduce the load on the tires. When the tires have no air pressure, they should not be parked on the spot. Instead, the wheels should be lifted.

When storing unused crane tires, they should be kept away from sunlight, oil, acids, flammable substances and chemical corrosions. All tires should be stored in a cool, dry and dark indoor area. Tires should be placed upright and it is strictly prohibited to lay them flat, stack them or hang them in a string. The storage period shall not exceed three years. If inner tubes need to be stored separately, they should be filled with an appropriate amount of air and must not be folded, placed flat or stacked. When not stored separately, it should be placed in the outer tire and inflated appropriately.

The above are the precautions to prevent tire wear during the use of cranes. Only when the tires are in good condition can the normal operation of the crane be guaranteed.
