The key to the safety of four-column lift operation lies in the material selection and product inspection standards of the key components of the lift. The first is the manufacturing materials, manufacturers of steel wire rope, chain and key components to undertake the stiffness, strength and installation accuracy of the manufacturing management and factory products must be strictly controlled; As the direct user of the product, we should pay attention to the quality of the product when choosing the double-column lifting machine. The whole double column lifting machine industry should pay more attention to intellectual property protection while improving the product technical content and manufacturing level, in the double column lifting machine patent application, China's double column lifting machine manufacturers should focus on the column bearing, hydraulic control, safety protection devices and other aspects of research to enhance the overall technical strength of the industry.

For auto repair shops and manufacturers that use lifts more frequently, the ability to quickly solve vehicle problems when there are more vehicles is an important means to improve customer satisfaction, and it is also an important way to create wealth for repair shops/factories. At the same time, for the maintenance factory, it may be affected by the price of the high-price double-column elevator products, but the purchase of a fast double-column elevator can improve the speed of automobile maintenance, which can save time and improve maintenance efficiency, so the development of faster lifting speed of the double-column elevator has a relatively large market.

To perform the following tasks on a monthly basis:

one Tighten anchor bolts, torque 150 Newton/m;

2. Check all joints, bolts or pins to ensure good connections;

3. Grease the slide, chain and wire rope;

4. Visual inspection of all hydraulic lines for wear and oil leakage;

5. Check that the safety mechanism is in good working order;

6. Lubricate all pulleys and pins with 90Wt gear oil;

Note: All anchor bolts need to bear normal torque. If a bolt cannot bear normal force, stop using the lift until a qualified bolt is replaced.

The following work is required every six months:

one Visually inspect all moving parts for possible wear, dryness and damage;

2. Check and adjust the tension of the wire rope according to the situation to ensure the parallel operation of the lift;

3. Check whether the column is perpendicular to the ground;

4. Check the rubber support pad and replace it if necessary;

5. Check whether the safety protection device is in normal working condition.

Wire rope inspection and maintenance:

All hoisting ropes should be replaced every 3 to 5 years, or when damage is visible. As long as the wire rope is properly maintained, the service life of the wire rope can be extended. For example, use 90Wt gear oil lubrication or wire rope lubricant to lubricate wire rope! These oils/lubricants go deep into the fibers to prevent damage. The lift is recommended to be lubricated every 3 months (4 times a year). At the same time, print the maintenance schedule and post it in the maintenance workshop to remind the next follow-up time at any time.

Every working day, as far as possible, any visible part of the wire rope should be observed in order to find damage and deformation. When the wear, broken wire, broken strand, rust, stretching, bending, deformation, fatigue, diameter, rope core exposure, etc. of the rope meet the replacement standards stipulated in the relevant regulations, please replace the new rope in time, otherwise it will face risks.

Regular maintenance can ensure the normal use of the lift, reduce the failure rate, extend the service life of the lift, so as to ensure the normal maintenance work.
