Guide rail lift maintenance knowledge
1) Before use, it should be air-lifted once to observe whether each part is normal. If there is any defect, it should be stopped;
2) During the maintenance and cleaning of the lifting platform, it shall be carried out after propped up the safety brace.
3) When the battery display is less than 40, charge it in time. Check the battery water when charging. If it is less than 20ml, you must add water.
4) Electrical and hydraulic systems should be maintained by professionals.
5) When the equipment is used for about 2 months (according to the actual frequency of use), a grease should be added to the rotating parts;
6) Check the working status of the hydraulic lifter pin every month. If it is found that the pin set screw is loose, be sure to pin tight to prevent the pin from coming off and causing accidents.
7) The hydraulic oil should be kept clean and replaced every 6 months;
8) It should be noted that it should be used indoors and outdoors. When it is used outdoors, it should be used on geologically hard ground in order to avoid subversion. Adjust the chain screw and adjust the safety rope once every 20 times. When using it, it can not be stopped. Work on slopes with a slope of more than 30° to prevent the elevators from falling; 4. Maintenance methods and measures for self-propelled lifting platforms For mechanized construction companies, whether the technical condition of the construction machinery is good or not is a direct factor for the normal production of the enterprise. In the case of hydraulically driven construction machinery, the normal operation of the hydraulic system is a major indication of its good technical condition. The qualified hydraulic oil is the guarantee for the reliable operation of the hydraulic system. Proper maintenance is the basis for the reliable operation of the hydraulic system. For this reason, based on the work practices, I have made a cursory discussion on the maintenance of hydraulic systems for construction machinery in the general operating environment.
1) Choosing the right hydraulic oil Hydraulic oil plays the role of transmitting pressure, lubrication, cooling and sealing in the hydraulic system. The improper selection of hydraulic oil is the main reason for the early failure and durability degradation of the hydraulic system. The hydraulic oil should be selected according to the grade specified in the random “operating instructionsâ€. When special oils need to be used, the performance should be the same as the original grade. Different brands of hydraulic oil can not be mixed to prevent the hydraulic oil from producing chemical reactions and changing properties. Dark brown, milky, odor-free hydraulic oil is a deteriorating oil and cannot be used.
2) The prevention of solid impurities from mixing into the hydraulic system The clean hydraulic oil is the life of the hydraulic system. There are many precision parts in the hydraulic system, some have small holes, some have gaps, and so on. If the solid impurities intruded will cause the precision joints to be damaged, hairpins, oil channel blockage, etc., endanger the safe operation of the hydraulic system. Common solid impurities invade the hydraulic system through: impervious hydraulic oil; impure cleaning tools; inadvertent refueling and maintenance, carelessness; and descaling of hydraulic components. Solid impurities can be prevented from invading the system in the following ways:
3) Refueling maintenance A. The hydraulic oil must be filtered and refilled when refueling, and the refueling tool should be cleaned reliably. It is not possible to remove the filter at the tank filler port in order to increase the refueling speed. Refuelling personnel should use clean gloves and work clothes to prevent solid impurities and fiber impurities from falling into the oil.
B. When dismantling, remove the cover of the hydraulic oil tank, the filter cover, the testing hole, the hydraulic oil pipe, etc., and avoid the dust when the system oil channel is exposed. The dismantling site must be thoroughly cleaned before opening. When disassembling the hydraulic fuel tank cap, remove the dirt around the fuel tank cap. After unscrewing the fuel tank cap, remove any debris that remains in the joint (do not flush it with water to prevent water from seeping into the tank). Make sure that the tank cap can be opened after cleaning. If you need to use the wiping material and the hammer, you should select the wiping material that can not get rid of the fiber impurities and the special hammer that attach the rubber on the striking surface. Hydraulic components, hydraulic hoses should be carefully cleaned, and then assembled with high pressure air. Use a genuine, well-packed filter cartridge (the internal packaging is damaged, and although the filter cartridge is in good condition, it may not be clean). Clean the filter at the same time when changing the oil. Before installing the filter element, clean the inside of the filter case with dirt by using a wiping material.
C. The hydraulic cleaning and cleaning oil of the hydraulic system must use the same hydraulic oil as that used in the system. The oil temperature should be between 45 and 80°C. Use large flow rates to remove impurities from the system as much as possible. The hydraulic system must be cleaned more than three times. After each cleaning, all the oil is released from the system when the oil is hot. After cleaning, clean the filter and replace it with a new one.
