Hui CenElevatoMotor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Car mounted lifting platform: The car mounted lifting platform is designed to improve the mobility of the lifting platform by fixing it to a transport vehicle or truck. It receives power from the car engine and achieves the lifting function of the car mounted lifting platform. To adapt to high-altitude operations inside and outside the factory area.
Hui Cen.It is prohibited to work on unstable structures (such as asbestos tile roofs). To prevent accidental boarding, warning signs should be hung at necessary locations of this structure.
Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.
.The main device does not engage. When this fault occurs,Hui CenElectric hydraulic lifting platform truck, check whether the three-phase power supply is normal,Hui CenIndoor hydraulic lifting platform, whether the internal and external emergency stop button switches, the electric lock switch are turned on whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump,Hui CenIndoor hydraulic lifting platform car, motor, valve, and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.
After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
What are the requirements for the pit? This type of cargo elevator only needs 15-30 centimeters and does not require too much space. The installation of scissor type hydraulic cargo elevators is different from that of guide rail type hydraulic cargo elevators. The scissor lift cargo elevator has a large load-bearing capacity, and the pit depth needs to be set at around 40-70 centimeters. It can also be designed according to customer on-site needs.
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.
Quality management.The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank, the partition in the traditional oil tank cannot settle dirt. A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far, The hydraulic oil tank has more heat dissipation effect.
I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.
Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.
After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
A complete range of products.The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance, cleaning, and replace the cleaning hydraulic oil to clean.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
The undercut length of the weld mm should not exceed 10% of the weld seam, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.
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 70%. 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.
An inverter can also generate high noise. When the power supply voltage is lower than 85% of the rated voltage, dust or rust is poor, and the device will produce; Buzz&# quo; Noise.
