Tunnel mucking loader tire maintenance is also an important course, why do you say that? The tunnel mucking loader tires are directly related to the progress of our project, so the reasonable use of tunnel mucking loader tire maintenance and maintenance is also what our tunnel mucking loader operators should do. Reducing the tire mucking loader tire usage cost is the root cause of our open source throttling.
1. Every time you purchase a new tunnel mucking loader tire, you should strictly accept it according to the requirements, and engrave or brand your own number in the mine on its side. A tunnel mucking loader tire file was established to record the main contents of the tunnel mucking loader tire specifications, manufacturer, date of use, mileage, tread wear, and number of retreads.
2. After the acceptance of the tunnel mucking loader tire, when it is put into stock, it should be sorted according to category, specification, pattern type, factory P, carcass material type, structure type, etc., and the storage time should be recorded at the same time according to the time Use sequentially. The stored tunnel mucking loader tires should be placed upright on the tire frame, and should be rotated regularly, and must not be hung through the core and stacked to prevent deformation. The inner tube should not be folded or stacked flat, but should be inflated and suspended on a semi-circular wooden stick.
3. The tunnel mucking loader tires that have been removed from the car and ready to be sent for refurbishment should be properly kept before refurbishment, and should not be exposed. Sun and rain will deteriorate the tunnel mucking loader tires. Do not stack them.
4. Before setting up each caster after each shift, the driver should carefully check the condition of the tunnel mucking loader tires, use a small hammer to beat, and listen to the sound to distinguish whether the tire pressure is normal and check the valve for leaks Whether the nut of the mucking loader is loose or not. Fill in the results of the inspection on the list. If you find a problem, report it immediately, and you cannot use it with "illness".
5. Regularly check the tire temperature during driving. In the case of overspeed, overload, abnormal inflation, sudden braking, uphill and downhill slopes and many corners, the tread temperature is easily increased, which will make the rubber soft. At this time, the tunnel mucking loader tire is prone to delamination or shoulder "Fat up" and other accidents. When it exceeds the specified temperature, it should stop to dissipate heat.
6. Maintain the normal inflation pressure of the tunnel mucking loader tire. The inflation pressure above or below the rated value is detrimental to the service life of the tunnel mucking loader tire. If the pressure is too low, the tunnel mucking loader tire deforms greatly and generates heat, which is easy to cause cracks in the side of the tire, thereby accelerating the fatigue of the cord or delamination, resulting in early damage to the tunnel mucking loader tire; the tire pressure is too high, then Increasing the contact pressure at the center of the tread causes excessive wear or slip of the crown, increases the degree of bumping of the vehicle 9 and deteriorates the cushioning performance, thereby increasing the wear rate of the bottom parts of the vehicle. Check the air pressure of the "cold tire" once a week. When the pressure differs from the specified value by 0.2 kg / cm, it must be adjusted. If the air pressure drops by 0.7 kg / cm during the week, a careful inspection must be carried out. Remove the tunnel mucking loader tire and send it for repair.
