Maintenance and repair of hydraulic lifts

Scissor lift  developments are in a peak state, because most manufacturers or individuals in order to improve the utilization of space, more options multistory building, which also requires a device to facilitate the drop down to enhance cargo. Therefore developed a high capacity lift to aid the production and transport of goods. Construction elevator that is safe and has a large load capacity, but also in the use and maintenance companies are more convenient, makes this particular industry has faster development.
1 hydraulic oil if found dim tacky or foreign matter, should be replaced to maximize job ahead
(2) Remove and disassemble the lift down valve, the plunger blowing with compressed air, and then loaded refitted.
3 Check all hydraulic pipes and fittings. Pipeline not have broken, can not have loose joints, it is necessary to tighten all fittings.
Monthly maintenance lifting platform
4 parts are filling some of the oil, extending the lift bearing life. Check the hydraulic lift wheel, intermediate shafts and bearings, cylinder pin and bearing, boom hinge shaft and bearings for wear.
5 between any part of the hydraulic system, it is necessary first of all relief to avoid pressure oil spray, lift table Passed decline.
6 shall be arbitrarily adjusted relief valve. Hydraulic lift system for each component are under pressure in the demarcation work. Any adjustment relief valve, the hydraulic system may cause abnormal operation.
7 below the lift working platform inspection, necessary Diaozhu support lift work platform, to prevent lift Passed down.
8 non-professional staff shall not disassemble appliances to prevent electric shock or incorrect connections.
9 has often check the bolts, switches, safety devices are loosening and failure.
  Lifts in use should pay attention to, must be placed on a solid flat surface to prevent tipping when working. Press the "up" or "down" button to make the table movements. If the table does not move, should immediately be shut down for inspection. Found that electric lift operating pressure is too high or abnormal sound, immediately shut down inspection, in order to avoid mechanical devastated; regular monthly checks pivot pin work status, such as found axle pin, screw loose, must be locked to prevent the axle pin off causing the accident.
  Maintenance and repair needs is a long and patient work, so to reduced failure rate and increase the maximum safety benefit rate
