In many cases, factories, floors, terminals and other places after the installation of lifting platform, there will be some adverse reactions, there will be some of these problems.
    A part of the casting, processing and other defects in the assembly and debugging is difficult to find, because of the loosening of mechanical parts, vibration and machine heat, the machine's sealing surface and pipe joints, etc., will leak; However, due to the operation of the vibration, the impact of this defect is exposed, the performance of leakage (infiltration) oil (water). Therefore, the run-in period prone to leakage phenomenon.
    Second, poor lubrication, due to the new assembly of the parts with a small gap, and because of assembly and other reasons, it is difficult to ensure the uniformity of the gap, lubricants (grease) is not easy to form a uniform surface of the oil film to prevent wear. Thereby reducing the lubrication performance, resulting in early wear and tear of the machine. Serious will result in precision with the friction surface scratches or occlusal phenomenon, leading to the occurrence of failure.
    Third, the occurrence of loose, new parts of the assembly, there is a geometric shape and with the size of the deviation, in the initial use, due to shock, vibration and other alternating load, as well as heat, deformation and other factors, coupled with wear too fast And other reasons, easy to make the original tightening parts of the loose.
    Fourth, the wear speed, due to the new machine parts processing, assembly and adjustment and other factors, the friction surface rough, with surface contact area is small, the surface pressure situation is uneven. During the operation of the machine, the parts of the surface of the concave and convex parts of the friction with each other, grinding down the metal debris, but also as abrasive, continue to participate in friction, more speed parts with the surface wear. Therefore, the run-in period is likely to cause wear of parts (especially with the surface), wear speed. At this time, if the overload operation, it may lead to damage to parts, resulting in early failure.
    Fifth, the operation errors, due to the structure of the machine, the performance of the understanding is not enough (especially the new operator), easy to cause malfunction due to operational errors, and even cause mechanical accidents.
