How to maintain the hydraulic lift freight elevator?

The maintenance of the scissor lift is different in each season, because the temperature difference is different, so in winter, you should choose the correct method for maintenance and maintenance work, because the winter weather is colder, It will cause the equipment to have various adverse phenomena due to the influence of temperature, so maintenance and maintenance work is very important. Know how to maintain the scissor lift in winter?

1. At low temperature in winter, the materials of the main stress components of the scissor lift must not only meet the requirements of strength, but also meet the application of attack toughness. The welding structure content of high-temperature stressed components has a great influence on the welding thermal stress and stress relaxation, so the layout of the platform should be selected.

2. However, for the selection of hydraulic oil for scissor lifts in winter, the viscosity of hydraulic oil is very important. At low temperature, the hydraulic oil of poor quality will also deteriorate the lubricating performance, and the movement resistance between the parts will also increase, and the parts will be damaged, so extra care should be taken when using hydraulic oil at low temperature.

3. When the gearbox, transfer case, drive axle, hoisting mechanism, and slewing mechanism operate at low temperature, the grease should be selected from gears with high viscosity target, low freezing point and good slipperiness Oil, otherwise it will lead to obvious decline in transmission compliance, increased wear and tear of transmission parts, heavy and heavy duty transmission and transfer case, and difficult shifting.

Non-electrical professionals are not allowed to disassemble and assemble electrical appliances at will to prevent electric shock or misconnection. When it is necessary to enter the working platform of the lithium pallet truck platform for maintenance, the working platform of the lifting platform must be suspended. To prevent the lifting platform from falling suddenly, causing casualties;

Non-professionals are not allowed to arbitrarily adjust the relief valve. Each component in the hydraulic system is working under the specified pressure. , may cause the hydraulic system to operate abnormally. There will be unnecessary damage to people, machines and objects; before unloading any part of the hydraulic system, the pressure must be unloaded first to prevent the pressure oil from spraying out and the worktable suddenly sliding down; some lubricating oil is added between the corresponding moving parts to extend the bearing life. life; check the oil quality and oil level of the hydraulic oil. The lift platform is raised all the way. In this position, the hydraulic oil level should be 40-50 mm above the bottom of the tank. Whether the hydraulic press is dark, sticky or has foreign matter such as grit, if found, the 120# hydraulic oil should be replaced in time.

In winter, if you want to make the scissor lift work normally, you must do a good job in maintenance work, which will not only increase the speed of work, but also help prolong the service life of the electric pallet lift truck, and will also bring the business For the greater benefit, how to maintain the hydraulic lift freight elevator in winter?
