Correct maintenance measures for electric mobile lifts

by:Powerston     2021-06-02
The principle of the electric mobile construction lift is to use the hydraulic lift plus the electronic integrated controller. It is convenient to construction lift and adjust the height in time. Considering safety issues, it is generally equipped with a non-slip insulating plastic water wave engraving plate, which is easy to replace and is beautiful in general. Generous, truly safe and fast! First, the maintenance and maintenance of the mechanical equipment of the electric mobile elevator 1. During the use of the mobile elevator, always check whether the various mechanisms are operating normally and whether there is noise. If a fault is found, it must be eliminated in time. 2. Electric Mobile elevators often check all wires and cables for damage. Bandage and replace the damaged parts in time. At the same time, the lubrication of the gearbox, gearbox, external gear and other parts and the hydraulic oil are in accordance with the requirements in the lubrication table 3. The brakes of each mechanism are frequently checked and adjusted the gap between the brake shoe and the brake wheel to ensure flexibility and reliability. There should be no dirt on the friction surface, and the dirt must be washed off with gasoline or thinner .4. Check the connection of each part frequently, and tighten if there is any looseness. The connection bolts of the mobile elevator body should be checked for tightness when the body is under pressure, and all connecting shafts must have cotter pins, and they must be fully opened. 5. Pay attention to check whether there are broken wires and loose strands in each part of the wire rope. If it exceeds the relevant regulations, it must be replaced immediately. 6. The contact surface of each part of the brush should be kept clean, and the pressure of the brush should be adjusted so that the contact area is not less than half. The control boxes, distribution boxes, etc. are always kept clean, and the dust on the electrical equipment is cleaned in time. Second, the seasonal maintenance measures of the electric mobile elevator 1. The reasonable choice of low-temperature steel, at low temperatures, the materials of the main stress components must not only meet Strength requirements must also meet the requirements of impact toughness. The welding structure of low-temperature stressed components has a great influence on welding thermal stress and stress concentration, so the mobile elevator should choose the structure of the platform. 2, hydraulic oil, lubrication Reasonable selection of grease and diesel oil. The lifting cage and luffing, rotation and expansion of the outrigger system of the aerial work vehicle and the lifting cage operation are all transmitted by hydraulic oil as the working medium. Therefore, special attention should be paid when choosing hydraulic oil for low temperature. .3. Lubricating oil, gearbox, transfer case, drive axle, hoisting mechanism, and slewing mechanism should be selected as gear oils with high viscosity index, low freezing point and good lubricity when operating at low temperatures, otherwise it will cause transmission The efficiency is significantly reduced, the wear of transmission parts is increased, the transmission and transfer case are heavy, and the gear shift is difficult.
