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, and simple maintenance compared to the scissor fork type elevator.

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,TruvaHydraulic lifting platform, 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.

Truva.The above are common situations, 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.

.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.

When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, even if the butter is polished to increase its properties.

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.

Clean the surface of the base and install anchor bolts. If the construction elevator is installed on the floor, use a pad iron under the base screws to increase the force surface between the nut and the floor, in order to reduce the impact of the nut on the floor; Insert steel plate gaskets of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite; After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and press it tightly

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.

Welcome calls .The cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced 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

The manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.

Mobile is a type of cargo heavy machinery equipment with good adjustment reliability and wide application fields,TruvaHydraulic lifting table lifting, suitable for automated production lines

Honesty and mutual benefit.When placing materials on the platform, they should be placed in the middle of the platform as much as possible. The weight of the goods should be within the standard load range of the equipment and the volume of the goods should not exceed the platform size of the equipment. Otherwise, materials and lifting platforms may be injured and dangerous accidents may occur. High priced and various specifications of elevator manufacturers provide timely supply, with high cost-effectiveness,TruvaFixed electric hydraulic lifting platform, and have become the preferred brand for many wire products. Welcome to purchase!

The manufacturer of hydraulic cargo elevators tells you the precautions for high-altitude operations.

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.

Truva.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.

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.

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.
