All users who have used lifting machinery such as electric lifts, lifting platforms, hydraulic lifting platforms, boarding bridges and lifts know that the technical performance of the lift is a direct factor related to the normal production of the enterprise. As far as hydraulic drive lifting machinery is concerned, the normal operation of the hydraulic system is an important guarantee for its good technical performance. Qualified hydraulic oil is the guarantee for the reliable operation of the hydraulic system, and correct maintenance is the foundation of the reliable operation of the hydraulic system. Therefore, when we use hydraulic lifting platforms, we must take some necessary maintenance measures to ensure that the construction lift can work better for us, to ensure personal safety and extend the service life of the lift. 1. Selection of hydraulic oil: Hydraulic oil plays the role of transmitting pressure, lubricating, cooling, and sealing in the hydraulic system. Improper selection of hydraulic oil is the main reason for the early failure of the hydraulic system and the decrease in durability. The hydraulic oil should be selected according to the model specified in the lifting cage
platform (instruction manual). In case of special circumstances, other oils should be used instead, the hydraulic oil should be selected with the same performance as required. Do not use it indiscriminately, otherwise it will cause chemical reaction and performance changes of the hydraulic oil (note: the use of deteriorated hydraulic oil is strictly prohibited). When you refuel, you must filter before refueling, and the refueling tools must be clean and tidy. Don't add it directly without a filter in order to save trouble. Second, maintenance is necessary: u200bu200bdisassemble the hydraulic oil tank filler cap, filter cap, inspection hole, hydraulic tubing and other parts to avoid dust when the system oil passage is exposed. The disassembled parts must be thoroughly cleaned before opening. For example, when removing the hydraulic oil tank filler cap, first remove the dirt around the fuel tank cap, unscrew the fuel tank cap, remove the debris remaining in the joint (not flush with water to prevent water from seeping into the tank), and open the fuel tank cap only after confirming that it is clean. If you need to use a wiping material and a hammer, you should choose a wiping material that does not remove fiber impurities and a special hammer with rubber attached to the striking surface. The hydraulic components and hydraulic hoses should be carefully cleaned and assembled after drying with high-pressure air. Use genuine filter elements with intact packaging (the inner packaging is damaged, although the filter element is intact, it may be unclean). Clean the filter at the same time when changing the oil. Before installing the filter element, use wiping materials to carefully clean the bottom dirt in the filter housing. Third, the hydraulic lifting platform must be evenly loaded and placed: when lifting heavy objects, the elevator must carry the goods in strict accordance with the allowable load capacity of the machine (otherwise safety hazards will occur), and pay attention to the placement of the goods. Is it evenly placed? If the goods are placed to one side or a corner, the method of placing the goods must be adjusted in time to ensure that people, machines, and objects are not damaged, which is more conducive to production. Fourth, the operation of the hydraulic lifting cage platform should be gentle and smooth: the lifting platform should be used with care during work, and should not be used arbitrarily, otherwise impact load will be generated during work, which will cause continuous failure of the lifting platform, which affects production and reduces the elevator’s cost The service life and the result of the impact load: on the one hand, it will cause early wear, fracture, and breakage of the components of the mechanical structure of the elevator. On the other hand, it will generate impact pressure in the hydraulic system, which will damage the hydraulic components, oil seals and The pressure joint of the high-pressure oil pipe joint and the rubber pipe fails prematurely, oil leaks or pipe bursts, and the oil temperature rises due to frequent operation of the overflow valve.
