How to determine the installation length of a double column car maintenance lift

What does installation length mean? Do you want to ask about the spacing between the two columns?

The structure, operation methods and precautions of the automobile double-column lift should be removed from the equipment and sundries that hinder the operation near the lift before use, and check whether the operating handle is normal.

The operating mechanism is sensitive and effective, and the hydraulic system does not allow crawling. When supporting the vehicle, the four corners should be on the same plane, and the height of the corner rubber pad should be adjusted to make it contact the supporting part of the vehicle chassis.

Safety hazards: Automobile lifts are used in special mechanical lifting equipment commonly used in automobile repair and maintenance units, and are widely used in the repair and maintenance of small cars such as cars. The double-column car lift can save a lot of ground space while lifting the car in the air, which is convenient for ground operations.

However, in order to save the most material, the floor is generally removed for double-column car lifts. Because there is no bottom plate, the torsion of the column needs to be offset by the ground, so the requirements for the foundation are very high, and if there is a beam (gantry lift), it will be offset by the beam.

The design of the structural ordinary double-column lift mainly includes the design of the lifting device, the design of the column, the design of the support mechanism, the design of the balance mechanism and the design of the insurance mechanism.

Before operation and use, the equipment and sundries that hinder the operation near the lift should be removed, and the operating handle should be checked to see if it is normal. The hydraulic system does not allow crawling.

After the lifting vehicle enters, the lifting machine support block should be adjusted and moved to the lifting point specified by the model, and the lifting arm should be reduced to the minimum length as much as possible, and the lifting rubber pad should be adjusted for uniform contact.

When supporting the vehicle, the four corners should be on the same plane, adjust the height of the corner rubber pad to make it contact the vehicle chassis support part, so that the lifting arm is lifted to the lifting rubber pad to completely contact the vehicle, and check whether the load has been firm.

Before putting down the vehicle, the vehicle should be lifted, the safety safety should be pulled apart, and then the vehicle should be slowly lowered by pressing the lowering handle until the lifting arm is lowered to the lowest, and the lifting arm should be removed and the vehicle should be driven out.

After the operation is completed, the debris should be removed and the area around the lift should be cleaned to keep the site tidy.

Precautions for the use of double-column lifts.

The vehicle is in the process of lifting or descending, and there can be no people at or near the bottom of the vehicle to ensure the safety of personnel;

After the vehicle is lifted to the specified height, it must be locked and the lock is effective before the staff can carry out the vehicle operation;

When the vehicle is being lifted or lowered, the operator must pay attention to the horizontal state of the vehicle and the state of the insurance to ensure that the insurance continues to rise or fall after it is valid.

The double-column car lift is suitable for gantry type houses with a height of more than 4m (left and right without floor type). Sun Huitong's house is 8 meters long, wide and high, and can be equipped with a double-column car lift.

There are two types of double-column lifts: symmetrical and asymmetrical. The four arms of a symmetrical lift are roughly equal in length, so that the center (or centroid) of the car is made so that the center (or centroid.

In the middle of the column, for pickups.

This symmetrical lift may be the best choice for routine maintenance of trucks and other types of cars.

But for some symmetrical double-column lifts with insufficient width between columns, the inability to open the doors after the car is lifted is a big disadvantage. The column of the asymmetrical lift is rotated back at an angle (about 30°) and the forearm is slightly shorter than the hindarm. When the car is parked in the proper position of this asymmetrical lift, the position of the car is shifted back a bit.

Double-column lifts can generally lift the car to a height of meters, and if the height of the lifted car exceeds the meter, it will reach the top, so the bottom of the meter building is more embarrassing, and can only repair relatively short vehicles, or repairmen work in half-squatting.

Gantry type, height needs to be more than 4m. The baseless type is on the left and right. If you build a larger-displacement SUV, it may not be suitable. The width is 4m. The length is based on the length of the car you have to repair the largest car yourself.

No oil leakage and non-standard operation!

1: Scissor lift classification.

Scissor lifts are divided into large shear (child-mother type), small shear (single scissor) lift 2: the current technical status of scissor lifts.

The earliest research scissor lift in China is Shanghai Bao Debao, starting in 1999, Bao Debao model is relatively bulky, the main quality problems are concentrated in the oil pipe explosion and platform out of sync, after 2000 the quality has been improved. But because it is not a batch, it is on the high side.

Other lift factories are also currently being studied, but often the technology is not good, not carrying the market to sell the best domestic quality scissor lift for Shenzhen Gaochang size scissors, Shanghai Detian size scissors, Xushida small scissors, simple structure, good synchronization type, and foreign countries on par.

3: Pre-purchase preparations.

1: Dig the foundation according to the size.

2: Prepare 380V electricity and high pressure gas.

3: One day of installation.

Just be careful not to hold yourself down.

Steps and precautions for use (1) Before each shift use, it must: a. Conduct daily inspection of relevant parts according to this manual. b. Check whether the oil level of the hydraulic oil tank is normal.

2) Before each shift is used, a no-load test must be carried out, and the power switch must be turned on according to the following procedures. b. Press the rising button, and the working platform should be able to rise normally. Release the button and the work platform should be able to stop reliably.

c, after rising to a certain height to stop, the working platform hook hangs, at this time the four hooks must be able to be reliably hung on the hanging plate in the column. d. When rotating the reversing valve for air supply, the four hooks should be completely separated from the hanging plate. e. Press the descending button, the working platform should descend at a normal speed, release the descending button, and the working platform should be able to stop reliably.

In the above-mentioned process, the machine should be free of abnormal noise and other abnormal phenomena. 1. Load operation of the lift (1) After driving the car onto the working platform, tighten the brake handbrake, and the driver evacuates the working platform. (2) Reliably place the anti-slip mounts on the front and rear of the car tires.

3) When there is no air supply, press the rise button to raise the working platform to the required height. (4) jog the lowering button, make the four hooks all reliably support on the hanging plate, and only then can enter the work area to carry out maintenance or adjustment operations. (5) After the repair or adjustment work is completed, jog the rising button, turn the reversing valve to the air supply position, make the four hooks out of the hanging plate, press the descending button, and the working platform descends.

6) When the working platform is lowered to the lower limit position, remove the anti-skid bearing and drive the car away from the working platform. 2. Precautions for use (1) There should be a special person to operate, maintain and repair the lift equipment, and it is forbidden to start the lift without reading this manual and without operation qualifications. (2) The car should be parked in such a way that its center of gravity is close to the center of gravity of the working platform.

3) It is strictly forbidden to overload the operation. (4) In the process of lifting and lowering the working platform, no person shall stay on the working platform or under the working platform. (5) It is forbidden to operate the unit in the event of a malfunction.

6) Personnel are allowed to enter the work area only after the four safety hooks have been identified. (7) The car staying on the working platform must tighten the hand brake and pad the anti-slip bearing. (8) When the lift is not in use, it should be lowered to the lowest position and cut off the power supply.

9) After the lift is used for a period of time, the wire rope will be elongated to varying degrees, so that the working platform is uneven and the four hooks can not be hung up synchronously. At this time, the length of the wire rope should be adjusted in time. (10) The machine should be maintained and overhauled in strict accordance with this manual.

1. Before each shift, the relevant parts must be checked daily according to the instructions to check whether the oil level of the hydraulic oil tank is normal;

2. Before each shift is used, a no-load test must be carried out, and the working platform should be able to rise normally by pressing the rising button, and the working platform should be able to stop reliably when the button is released;

3. After rising to a certain height, stop, hang the hook of the work belt platform, and the four hooks must be able to be reliably hung on the hanging board in the column;

4. When rotating the reversing valve for air supply, the four hooks should be completely separated from the hanging plate;

5. Press the descending button The working platform should be lowered at a normal speed, and the working platform should be able to stop reliably when the lowering button is released. In the above-mentioned process, the machine should be free of abnormal rental noise and other abnormal phenomena.
