All parts should be cleaned and carried out in a clean environment. The traction height of the mine car is ±3mm, the total width is ±5mm, the total height is ±8mm, and the total length is ±10mm.The car box should be installed symmetrically on the longitudinal center plane of the frame, and its symmetry tolerance is 5mm.The assembled mine cart should be placed on a special straight track for inspection, and the gap between a wheel and the rail surface is not allowed to be greater than 2mm.The mine car runs smoothly whether in a bend or a straight. All parts are painted with phenolic primer, and the body is painted according to the contract requirements. The appearance of the paint is required to be uniform, flat, consistent in color tone, complete coverage, and no brush marks, peeling, accumulation, and blistering defects.
