The existence of coal mining car is a relatively common existence in the machinery and equipment market today. It is the main existence of our company’s research and production for many years. The so-called narrow gauge mine car are common machinery and coal mining car used in mining production. They are widely recognized. For specific inspection standards, the editor summarizes the following for you.
The safety factor of the beams, bumpers, and bolts of the side dumping mine car is not less than 10; the wear of the connecting shackles and bolts does 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.
The cast steel has no cracks in the head, and the spring has no fracture or deformation. The stretch length of the elastic bumper is 10-30mm.
There should be no more than 1 hole in the 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 mouth should not exceed 50mm.
The bottom beam shall not be welded or cracked, the rivets on the head shall not be loosened, and the looseness of rivets and bolts in other side dumping mine car parts shall not exceed 10% of the total.
The coal mining 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.
According to the above five points, the inspection of narrow gauge mine car can help many customers to choose and use mine carts smoothly, and provide support and assistance for enriching mining production.
