The use of construction machinery is increasing. As we all know, many construction machinery transportation vehicles are used more and more, and the subsequent increase is the use of construction tires. When using engineering tires, we should pay attention to their disassembly and maintenance. Next, we will introduce the disassembly and maintenance methods of engineering tires.
1、 Strictly abide by the engineering tire inflation standard, check whether each part leaks after inflation, and regularly check the tire pressure to ensure compliance with the standard. Develop the habit of using a barometer to measure the tire pressure of the loader, which can not be judged by the naked eye. Ensure that the tire has a certain elasticity, make its deformation not exceed the specified range when bearing the specified load, and ensure that the equipment has good stability and comfort during driving. The air pressure of the spare tire should be relatively high to avoid running away for a long time.
2、 Correctly select and install engineering tires, and use corresponding inner tubes according to engineering tire specifications. Tires assembled on the same machine shall ensure the same brand, structure and performance. If this cannot be done, tires of the same brand, specification, pattern and type shall be assembled on the same axle; When replacing new tires, the whole vehicle or coaxial shall be replaced at the same time; Tyres with directional tread patterns shall be installed according to the specified rolling direction; When replacing with a new tire, install the new tire on the front wheel and the repaired tire on the rear wheel. In order to ensure driving safety, retreaded tires are not allowed to be used as steering wheels (front wheels).
3、 The engineering tires shall be transposed regularly. After the equipment has been driven for a period of time, the fatigue and wear degree of the front and rear tires are different, so they shall be transposed in time according to the regulations. There are two methods for changing tires: cross method and coaxial transposition method. The cross transposition method is applicable to the crane equipment that often runs on the road with large camber, while the coaxial transposition method is applicable to the equipment that often runs on the flat road.
4、 Control the temperature of the engineering tire. During the driving of the engineering machinery and equipment, the tire generates heat due to friction and deformation, which increases the temperature and air pressure inside the tire.
When the temperature of the engineering tire is very high, the method of deflating and depressurizing shall not be adopted, let alone splashing water on the tire to reduce the temperature, so as not to accelerate the damage of the tire. Stop in a shady place and rest until the tire temperature decreases. When the equipment stops on the way and arrives at the site, the parking habit of safe sliding shall be developed.
5、 Choose a flat, clean and oil-free ground for parking, and each tire should land smoothly, especially overnight. Pay more attention to selecting the parking place, and jack up the rear wheel if necessary. When the equipment is out of service for a long time, the frame should be supported with wooden blocks to reduce the load of tires; When the tire has no air pressure, it cannot be parked locally, and the wheel shall be jacked up.
6、 Engineering tires should be kept away from sunlight, oils, acids, combustibles and chemical corrosives. All tires shall be stored in a cool, dry and dark room. Engineering tires shall be placed vertically. It is strictly prohibited to put them horizontally, stack them or hang them in a string. The storage period shall not exceed three years. If the inner tube needs to be stored separately, it shall be filled with an appropriate amount of air and shall not be folded, placed flat or stacked. If it is not stored separately, it shall be placed in the outer tire and inflated appropriately.
The above is the summary of the disassembly and maintenance methods of engineering tires. I believe it will bring you some knowledge. At the same time, I hope you can maintain and maintain engineering tires more correctly and make their use time longer.
