Wu QiangManufaLoad bearing capacity: The lifting platform is placed on a horizontal support surface,Wu QiangHydraulic lifting platform Electric lifting platform, and the workbench is evenly loaded to 125% of the maximum load capacity. After lifting 100 times, each load-bearing component must not have deformation or cracks.
The undercut length of the weld mm should not exceed 10% of the weld seam, and the depth should not exceed 0.4mm.
Wu Qiang.High altitude work should always use tool bags. Tools with larger boarding bridges should be tied to sturdy components with ropes, and should not be placed randomly to prevent accidents caused by falling from a height.
Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes,Wu QiangManual pressure relief of hydraulic lifting platform, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.
.After 10000 hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.
Separate: Loading and unloading on different platforms.
Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of 220V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.
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, due to overload, insufficient power supply, the starting voltage drop is too large and the price of the cargo elevator is reduced.
Many high-rise cargo transportation often requires the use of hydraulic cargo elevators or transport elevators, but in practical applications, there is a strange phenomenon that more people choose to use hydraulic cargo elevators than elevators. Why is this? We are a long-term elevator manufacturer that welcomes inquiries
Introduction to the unloading lifting platform: The unloading lifting platform is a specialized auxiliary equipment used in conjunction with forklifts for cargo loading and unloading. With it, forklifts can directly drive from the ground into the interior of car compartments for batch loading and unloading operations. The warehouse unloading platform products use manual hydraulic power and do not require power supply. Only one person needs to operate to achieve safe and fast loading and unloading of goods. It can reduce a lot of labor,Wu QiangLifting table hydraulic pressure, improve the efficiency of loading and unloading operations, speed up the flow of materials, and obtain greater economic benefits.
property right.Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve and replace it if necessary.
For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.
The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
Test method.The speed circuit is the circuit that switches the motion speed and speed of the actuator in the hydraulic system of the guide rail hydraulic lifting platform. Mainly including valves, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits, and speed switching circuits.
Hydraulic cargo elevator sinking refers to the lifting of the cargo elevator equipment to a designated position, and after a period of time, the entire table surface will automatically descend by a certain distance under its own weight. The phenomenon of hydraulic cargo elevators naturally descending during the leveling process. such
Lifting mechanism: The workbench should be ensured to rise and fall smoothly and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, each load-bearing component must not have deformation or cracks.
When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, and continue running. The motor bearings should be smooth and outstanding.
