Specifications and maintenance of hydraulic lift table components

Hydraulic Lift Platform It is a unified whole, its main structure consists of multiple components. During operation, the parts complement each other and work together. Damage to any component may cause the equipment to malfunction. The following maintenance tips for hydraulic lift platform components are analyzed below.

I. Cables and Cable Conduits

1. Whether the spring function of the guiding device is normal;

2. Check whether the relative position of the cable support arm and the cable conduit is correct;

3. Whether the cable is twisted or damaged.

II. Transmission and Reduction Mechanism

1. Check whether the fastening bolts of the mechanical transmission device of the hydraulic lift platform are loose, especially whether the fastening screws of the lifting gear pair are loose;

2. Whether the heat dissipation of the motor heatsink and its function are good;

3. Whether the oil level in the gearbox has dropped.

III. Hydraulic Lift Platform Counterweight and its Hanging Wire Rope

1. Whether the wire rope is severely worn or broken;

2. Whether the basin-shaped gear device works normally and reliably;

3. Check whether the heavy-duty guide roller is firmly fastened.

IV. Electrical System and Safety Devices

1. Check whether the performance of the cage door electromechanical interlock device, upper and lower limit devices, single door, and double door interlock device of the hydraulic lift platform is good;

2. Whether the position of the limit iron on the guide rail frame is correct;

3. Brake: Check whether the braking torque of the test brake meets the standard;

4. Rolling element device: Check whether the fastening bolts of the roller support frame are firmly fastened.

V. Metal Structure

1. Whether the wall-mounted structure is stable, whether the bolts are loose, whether the surface protection is good, whether there is paint peeling and corrosion, and whether the frame is deformed;

2. Check whether the connecting bolts between the standard sections of the hydraulic lift platform guide frame are firm.

Precautions for using hydraulic lifts:

1. From the perspective of the hydraulic elevator itself, the equipment also wears out quickly during use. Due to the influence of parts processing, assembly, and debugging of the lifting platform, the friction surface is rough, the contact area of the mating surface is small, and the surface pressure is uneven. When the hydraulic lift works, the uneven parts on the surface of the parts are embedded into each other, and the worn metal fragments continue to participate in the friction as abrasives, making the matching wear of the parts and the surface faster.

2. The maintenance and lubrication of mechanical equipment are the same as those of machines. If the lubrication is poor, due to the smaller mating clearance and assembly of the new parts of the hydraulic lift, it is difficult to ensure the uniformity of the mating clearance. The lubricating oil is not easy to form a uniform oil film on the friction surface to prevent wear. Therefore, the lubrication efficiency is reduced, leading to abnormal early wear of parts. When the situation is serious, the friction surface of the precision pipe fittings will be damaged or blocked, leading to failure.

3. Loose parts are prone to occur in newly processed equipment. In the initial stage of use, due to the influence of alternating loads such as impact and excessive wear caused by factors such as heating and deformation, the original fasteners are easily loosened. Therefore, it is necessary to frequently check whether the equipment parts are loose.

4. If the seal is not tight, leakage may occur. Affected by loose parts, hydraulic lift vibration, and heating, the sealing surfaces and pipe joints of the machine will leak. Casting and processing defects are difficult to find during assembly and debugging, but due to vibration and impact during operation, the defect is exposed, manifested as oil leakage. Therefore, leakage is prone to occur during the running-in period.
