In many cases, after installing lifting platforms in factories, floors, docks, and other places, there may be some adverse reactions and various problems in the early stage. We have summarized some of the common problems and causes of hydraulic lifting platforms.

1, Leakage occurs due to the looseness, vibration, and thermal effects of machine components, resulting in leakage on the sealing surface and pipe joints of the machine; Partial casting, processing and other defects are difficult to detect during assembly and debugging, but due to vibration and impact during operation, these defects are exposed, manifested as oil leakage and water seepage. Therefore, leakage is prone to occur during the running in period.

2, Poor lubrication, due to the small fit clearance of newly assembled components and the difficulty in ensuring the uniformity of fit clearance due to assembly and other reasons, lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. This reduces lubrication efficiency and causes early abnormal wear of the components. In severe cases, it can cause scratches or biting on the friction surface of precision fit, leading to the occurrence of faults.

3, Loosening occurs when newly processed and assembled components have deviations in geometric shape and fitting dimensions. In the early stages of use, due to alternating loads such as impact and vibration, as well as factors such as heat and deformation, coupled with rapid wear and tear, it is easy for previously fastened components to become loose.

4, The wear rate is fast, and due to factors such as processing, assembly, and adjustment of new machine components, the friction surface is rough, the contact area of the mating surface is small, and the surface pressure condition is uneven. During the operation of the machine, the concave and convex parts on the surface of the parts interlock and rub against each other, and the metal debris that falls off serves as abrasives, continuing to participate in friction and accelerating the wear of the mating surfaces of the parts. Therefore, during the running in period, it is easy to cause wear and tear of components (especially mating surfaces), and the wear rate is fast. At this point, overloading operations may lead to damage to components and early failures.

Therefore, we need to take good care of and maintain the elevator to extend the service life of the hydraulic lift platform.
