The existence of mine car provides support and help for many mining production efficiency. Side Dumping Mine carts are a typical existence in the mining machinery and equipment market. Our company has a good understanding of the basic use and maintenance technology of narrow gauge mine car. The following are the basic standards for determining the integrity of narrow gauge mine car.
(1) The side dumping mine car runs smoothly. When one of the four wheels on the horizontal track is not in contact with the rail surface, the gap is not more than 3mm.
(2) The wheel shall not have cracks, the rim wear thickness shall not be less than 13mm, and the tread wear thickness shall not be less than 6mm for mine carts of 1t and below.
(3) The wheels are lubricated regularly and rotate flexibly. The swing of the wheel end surface: the rolling bearing does not exceed 2mm; the tapered roller bearing does not exceed 3mm.
(1) The safety factor of the beam, bumper, and bolt of the mine car is not less than 10; the wear of the connecting shackle and the bolt shall not exceed 15% of the original size. The bending of the chain link and the pin shall not exceed 10% of the diameter of the chain and the pin.
(2) The cast steel has no cracks in the contact, and the spring has no fracture or deformation. The stretchable length of the elastic bumper is 10-30mm.
(1) There should be no more than 1 hole in the narrow gauge mine car box larger than 50mm, the depth of the unevenness of each part should not exceed 50mm, the length of the crack should not exceed 100mm, and the diagonal length difference of the upper opening should not exceed 50mm.
(2) The side dumping mine car bottom beam must not be welded or cracked, the rivets on the head must not be loosened, and the number of loose rivets and bolts in other parts shall not exceed 10% of the total.
Determining that the side dumping mine car is in good condition based on the above three points is the focus of the attention and trust of customers and friends. For more in-depth understanding of the details of the mine truck, you can call the company for detailed consultation.
