If it is necessary to prolong the service life of the lifting platform, it is necessary to do a good job in the maintenance of the lifting platform, and to timely bind and replace the damaged parts, as well as to have enough lubricating oil in the transmission part, then it is necessary to regularly check, repair or replace the vulnerable parts, and for the mechanical bolts, especially the parts that often vibrate, if it is from the slewing ring The connecting bolts of the lifting arm should be checked to see if they are loose. If they are loose, they must be tightened or replaced, and it is necessary to drain the hydraulic oil, tighten the connector and take out the oil filter. In addition, after cleaning, they should be cleaned with compressed air, and then put back into the oil tank. They should be connected to the pipeline, and then they should be replaced with new oil. Do not inherit the old oil, Otherwise, the moving parts in the hydraulic elevator system will wear faster. In addition, the overflow valve cannot be adjusted arbitrarily, and some lubricating oil is added to the parts. If it is to prolong the service life of the elevator bearings, it is necessary to check whether the hydraulic elevator roller, intermediate shaft and bearing, cylinder pin shaft and bearing, boom hinge shaft and bearing are worn.
