Users should arrange dedicated personnel to operate hydraulic elevators formulate usage details and safety precautions for hydraulic elevators based on their own situation， and hang them on the
Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted and if the adjustment is ineffective， replace it with a new valve.
GilbertBased on the foundation plan， pay attention to alignment， and alignment to ensure the foundation level and various usage requirements. The access road for external construction elevators should be flat and have sufficient space for equipment parking.
Considering the oil level in the oil tank， when all hydraulic cylinders in the system are extended， the oil level in the oil tank should not be lower than the Z-low oil level， and when the oil cylinders retract， the oil level should not be higher than the Z-high oil level. In fact， most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators， in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators， to avoid any worries about after-sales service.
Tuberaceae The characteristics of the platform include reliable hydraulic system， simple operation， and rear hinge support.
The characteristics of the platform include reliable hydraulic system， simple operation， large load-bearing capacity， and rear hinge support.
Electrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors，GilbertHydraulic ladder， or damaged bearings， which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed， resulting in high noise; The electric motor is not firmly fixed and can also cause vibration， producing high noise.
After hours of elevator operation， perform minor repairs to the mechanical and electrical systems.
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 .% -.%. They are widely used as transmission components in elevators. Due to its large load-bearing capacity， light weight， smooth operation， no noise， suitable for high-speed transmission， high strength， it has become a commonly used rope for hydraulic elevators.
The hydraulic lifting platform is a manually movable type and reliable operation， and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power， and is also equipped with a hand pump for use in case of power outage. This series of platforms have the characteristics of flexible movement， stable lifting，GilbertHydraulic lifting table， and easy operation， and are mainly used in factories， government agencies， commercial stores and the construction and decoration industry.
Analysis projectRegularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
After long-term use of the automatic lifting platform equipment，GilbertHydraulic lifting table small， 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， due to overload， insufficient power supply， and a small cross-sectional area of the power supply cable， the starting voltage drop is too large and the price of the cargo elevator is reduced.
When installing， disassembling， and adjusting the rotating mechanism， attention should be paid to ensuring that the middle line is parallel to the middle line of the gear， and its meshing surface is not less than %. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.
Materials enter the production line at one end of the factory building， and the production process ends at the other end of the factory building with multiple separate platforms; This can greatly shorten the distance of material flow in the factory building.
Service firstThe combined platform is often used in small workshops with small volume of goods. However， because this platform needs to complete two functions at the same time， it inevitably increases the distance of handling tools/vehicles in the workshop.
Oil pipe leaks oil. Poor sealing of oil pipes， oil leakage， resulting in a decrease in pressure and a natural descent of hydraulic cargo elevators. It is recommended to carefully check whether the oil pipes are intact and undamaged.
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， 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 .MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above mm 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.
GilbertVolume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
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.
The vibration range is proportional to the lifting height. The higher the height， the larger the shaking range， especially for mobile hydraulic cargo elevators. When the working height exceeds meters， the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection， increase stability， and reduce shaking.
