The mobile freight lift manufacturers uses a hydraulic lift and an electronic integrated controller. It is convenient to lift and adjust the height in time. Considering safety issues, it is generally equipped with a non-slip insulating plastic water wave engraved plate, which is convenient to replace and the overall appearance is generous. Without the laborious effort of manually lifting a ladder, it is truly safe and fast, saving time and effort.As an elevator manufacturer, whether it is production, sales, or service, we are always thinking about customers. Since the product is produced, there must be related maintenance.The hydraulic oil plays the role of transmitting pressure, lubricating, cooling, and sealing in the hydraulic system. Inappropriate selection of hydraulic oil is the main reason for the early failure and durability of the hydraulic system. The hydraulic oil should be selected according to the brand specified in the instruction manual. When a substitute oil is needed in special circumstances, the performance should be the same as that of the original brand. Different brands of hydraulic oil cannot be mixed to prevent chemical reactions and performance changes of the hydraulic oil. Dark brown, milky white, and odorous hydraulic oil is deteriorating oil and cannot be used.Clean hydraulic oil is the life of the hydraulic system. There are many precision parts in the hydraulic system, some have damping holes, some have gaps, etc. The intrusion of solid impurities will cause strains, hairpins, blockage of oil passages, etc., and endanger the safe operation of the hydraulic system. Common ways for solid impurities to invade the hydraulic system include: dirty hydraulic oil; dirty refueling tools; careless refueling, repair and maintenance; desquamation of hydraulic components. It can prevent solid impurities from entering the system from the following aspects: When refueling, the hydraulic oil must be filtered and refilled, and the refueling tools should be reliable and clean. It is not possible to remove the filter at the fuel tank filler opening in order to increase the fueling speed. Fueling personnel should use clean gloves and work clothes to prevent solid impurities and fiber impurities from falling into the oil. During maintenance, disassemble the hydraulic oil tank filler cap, filter cap, inspection hole, hydraulic oil pipe and other parts. 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, and open the fuel tank cap after confirming that it is clean. If you need to use wiping materials and hammers, you should choose a wiping material that does not remove fiber impurities and a special hammer with rubber attached to the striking surface. Hydraulic components and hydraulic hoses should be carefully cleaned and assembled with high-pressure air drying. Choose genuine filter cartridges that are well packaged. 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. The cleaning oil must use the same brand of hydraulic oil as the system used, the oil temperature is between 45～80℃, and the large flow is used to take away impurities in the system as much as possible. The hydraulic system of the hydraulic elevator should be cleaned more than three times repeatedly. After each cleaning, let it out of the system while the oil is hot. After clean the filter of hydraulic elevator, replace the new filter element and add new oil.
