Ways to maintain the wear and tear of freight lift elevator
Correct maintain methods of freight lift elevator improves the lift span of the elevator. Here are several ways for how to maintain wear and tear of freight lift elevators.
Long-term use of freight lift elevator will cause wear and tear. So, what are the ways to maintain the wear of hydraulic elevators? Let’s take a look at it together! Hope it will be helpful to everyone.
Polish and grease the elevators
It is necessary to regularly polish the lubricating oil between the link pins of the hydraulic elevator to reduce the degree of wear between the components and reduce the noise, which can play a good preventive effect on the occurrence of safety accidents. Remove and disassemble the lowering valve of the hydraulic elevator, blow the plunger clean with compressed air, then install it, and re-install it. Check all hydraulic pipes and joints. The pipeline must not be damaged, the joints must not be loose, and all joints must be tightened.
Change hydraulic oil regularly
The quality and level of hydraulic oil. The freight lift elevator is raised all the way. In this position, the hydraulic floor should be 40-50 mm higher than the bottom of the box. If you find that the hydraulic oil becomes dark, sticky, or has foreign objects such as grit, it should be replaced in time. Regularly check the hydraulic hydraulic lift rollers, intermediate shafts and bearings, cylinder pins and bearings, boom hinge shafts and bearings for wear. Between any part of the hydraulic system, the pressure must be relieved first, so as to prevent the pressure oil from spraying out and the hydraulic lift table suddenly slipping.
Don’t adjust hydraulic lift elevator’s overflow valve arbitrarily
Do not adjust the overflow valve arbitrarily. Each element in the freight lift elevator system works under a defined pressure. Any adjustment of the relief valve may cause abnormal operation of the hydraulic system. When inspecting under the working platform of the hydraulic lift, the working platform of the hydraulic lift must be suspended and supported to prevent the hydraulic lift from falling suddenly.
Let professional staff do the maintain and install work
Non-professional staff are not allowed to disassemble or install electrical appliances at will to prevent electric shock or wrong connection. The hydraulic lift has been inspected and debugged before leaving the factory, and all technical indicators have reached the design requirements. When using it, only the power supply needs to be connected, and the hydraulic and electrical systems do not need to be adjusted. Drain and discard the hydraulic oil, tighten the joint and take out the oil filter. After cleaning it, clean it with compressed air, then put it back into the oil tank and connect the pipeline. Pay attention to the noise generated by the freight lift elevator when it is raised and lowered. If the noise is too large, immediately disconnect the power supply and check the cause of the noise. Check the freight lift elevator regularly.
