Tire maintenance skills for construction machinery and equipment
Tires also have a lifespan, so how to maintain them has become something we need to pay attention to. Below, I will mainly explain the inflation, selection, rotation, temperature, and environment of the tires.
One is to inflate in a timely manner according to regulations. After inflation, check for air leaks in all parts and regularly use a pressure gauge to check the tire pressure. Ensure that the tires have a certain degree of elasticity, and when subjected to specified loads, the deformation should not exceed the specified range. They should have good stability and comfort during driving. Considering prolonged running, the pressure of the spare tire should be relatively high.
The second is to correctly select and install tires, and use corresponding inner tubes according to tire specifications. The same brand and specification of tires should be installed on the same machine. When replacing a new tire, the entire machine or coaxial should be replaced simultaneously. The new tire should be installed on the front wheel, and the repaired tire should be installed on the rear wheel; Tires with directional patterns should be installed in the specified rolling direction; Refurbished tires are not allowed to be used as front wheels.
The third is to regularly rotate the tires. After the machine has been driven for a period of time, the front and rear tires should be replaced in a timely manner according to regulations. The cross displacement method is suitable for machines that frequently drive on larger arched roads, while the cyclic displacement method is suitable for machines that frequently drive on flatter roads.
The fourth is to control the tire temperature. Tires generate heat due to friction and deformation, which increases the temperature and pressure inside the tire. When the tire temperature is very high, the method of deflating and reducing pressure should not be used, let alone splashing water on the tire to cool it down. Instead, the tire should be stopped and rested in a cool and ventilated place, and driving can only continue after the tire temperature has decreased. When stopping on the way, it is important to develop a habit of safe sliding and choose a flat, clean, and oil-free ground to park, so that each tire can land smoothly. When the machine is loaded overnight, it is important to choose a suitable parking location and, if necessary, lift the rear wheels. When stopping for a long time, use wooden blocks to support the frame to reduce the load on the tires; If the tire cannot be parked on site without air pressure, the wheel should be lifted.
The fifth is tire anti-corrosion. Avoid storing tires in sunlight, as well as in areas with oil, acids, flammable substances, and chemical corrosive substances. Tires should be stored indoors at room temperature, dry, and in the dark. Tires should be placed upright and are strictly prohibited from being placed flat, stacked, or suspended in a string. The storage period shall not exceed 3 years. If the inner tube needs to be stored separately, it should be inflated appropriately. Otherwise, it needs to be placed inside the outer tube and inflated appropriately.
Sixth, pay attention to starting at low temperatures. The severe cold in winter increases the brittleness and elasticity of tires. When stopping for a long time or driving again after staying overnight, the clutch pedal should be slowly lifted to start smoothly. First, drive at low speed and wait for the tire temperature to rise before driving normally. After stopping on the ice for a period of time, the grounding area may freeze. Extra caution should be taken when starting to prevent the tread from being torn. When parking outdoors for a long time in winter, wooden boards or sand should be placed under the tires.
