Sihu Fixed hydraulic lifting platformVarious methods of use

The elevator is evenly distributed at any position on the guide rail at 150% of the maximum load capacity and should be stable at the maximum lifting height.

Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, and intensity of high-altitude operations.

Sihu .Usage and instructions for steel wire ropes in elevators: The steel wire ropes of the steel wire ropes require very high strength, usually made of high-quality carbon steel with a carbon content of 0.5% -0.8%. They are widely used as transmission components in elevators. Due to its large load-bearing capacity,Sihu Hydraulic small lifting platform, light weight, smooth operation, no noise,Sihu Hydraulic scissor type lifting platform, suitable for high-speed transmission, high strength, strong overload capacity, and reliable operation, it has become a commonly used rope for hydraulic elevators.

The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.

.After long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, insufficient power supply, and a small cross-sectional area of the power supply cable, the speed can only be adjusted by changing the flow rate. For variable displacement motors it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, speed regulation can change both the flow rate and the motor displacement.

Aluminum alloy elevators are different from other forms. This type of elevator is made of aluminum alloy material, which is lightweight and has a more beautiful appearance. The disadvantage is that it has a light load capacity and is only suitable for simple high-altitude maintenance work, and can only provide support for 1-2 people.

Separate: Loading and unloading on different platforms.

In case of strong wind of level 6 or above, rainstorm, thunder, the work at heights in the open air shall be stopped at the boarding bridge.

The development of elevators is at its peak, as many manufacturers have chosen more multi-story buildings to fully utilize the site, so they also need a device to facilitate the improvement of goods.

Total quality assurance.The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil, the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, Mixing air into the oil to eliminate: The concentricity should be adjusted to within 0.1MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above 400mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, it will cause cavitation under high pressure and cause significant noise. At this point, it is necessary to exhaust the air in a timely manner.

When using an electric mobile scissor lifting platform outdoors, if the wind force exceeds level 5, please stop using it; When the lifting height exceeds 10 meters, the wind ropes at the four corners of the hydraulic lift platform should be tightened and fixed, and the support legs should be reinforced for protection and stability to avoid safety accidents caused by excessive swinging of the electric lifting platform

Regularly inspect the hydraulic lifting equipment of the upper and lower materials to ensure the safety of the rail type elevator and the safety of the material supply to the rail type lifting platform.

After 10000 hours of operation on the hydraulic lift major repairs will be carried out to the mechanical and electrical systems.

equipment maintenance .Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.

When the hydraulic cargo elevator needs to work, first connect the power supply and press the button to drive the motor of the hydraulic power unit to drive the gear pump. The hydraulic oil forms a certain pressure through the vane pump and passes through the oil filter; Explosion proof electromagnetic directional valve; Throttle valve; Hydraulic control one-way valve; The balance valve enters the lower end of the hydraulic cylinder, causing it to move upwards and lift heavy objects. The hydraulic cylinder moves downwards (i.e. the weight drops), the explosion-proof electromagnetic directional valve of the hydraulic oil enters the upper end of the hydraulic cylinder, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve; Hydraulic control one-way valve; Throttle valve, explosion-proof electromagnetic directional valve.

The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years, with the advantages of higher lifting height, stable operation, and simple maintenance compared to the scissor fork type elevator.

Sihu . There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity,Sihu Hydraulic lifting platform, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times Make the damping hole unobstructed, repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.

The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.

The hydraulic pump produces noise. When the hydraulic elevator rises, the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.
