The lifting plate, with its flexible lifting function, is widely used in industrial production, logistics and warehousing and other fields. However, frequent use will cause the components of the equipment to gradually wear out and age. If not maintained and serviced in time, it is easy to cause malfunctions, affecting the safety and efficiency of use. Reasonably determining the maintenance cycle is the key to ensuring the stable operation of the lifting plate.

　　The frequency of use is an important basis for determining the maintenance cycle. For lifting plates that are frequently used every day, such as those that operate continuously in large logistics warehouses and production lines, it is recommended to conduct a basic inspection and cleaning after the end of each day's operation. Check for any signs of oil leakage in the hydraulic pipelines, observe whether the lifting chain and steel wire rope are worn or broken, and ensure that the connecting bolts of each component are not loose. Clean the dust and debris on the surface of the equipment and the workbench to prevent them from entering the interior of the equipment and causing component jamming or wear. Conduct a comprehensive maintenance once a week, replenish the hydraulic oil in the hydraulic system, and check whether the oil quality is clean and whether there is any emulsification or deterioration. Lubricate key transmission components, such as bearings and guide rails, to reduce frictional losses; Test the lifting function of the equipment, check whether the lifting speed is stable, and whether there is any abnormal noise or vibration.

　　For lifting plates with a relatively low usage frequency, no more than three times a week, a basic inspection should be conducted once a week, paying attention to whether there is any damage to the appearance of the equipment and whether the connection parts are firm. A deep maintenance should be carried out once a month. In addition to completing the weekly maintenance items, the electrical control system should also be inspected to check whether the circuit connections are reliable and whether the electrical components are working properly. Measure the pressure of the hydraulic system to ensure it is within the specified range. If there is any deviation, adjust it in time. In addition, no-load and load operation tests are conducted on the equipment to simulate actual usage conditions and identify potential fault hazards.

　　The working environment also significantly affects the maintenance cycle. If the lifting plate works in harsh environments, such as high-temperature, humid and dusty places, the maintenance cycle needs to be shortened. In high-temperature environments, hydraulic oil is prone to evaporation and deterioration, and the aging speed of rubber seals accelerates. It is recommended to check the status of the hydraulic oil every two weeks and replenish or replace it in a timely manner. Check the seals every month. Replace them immediately if any aging or damage is found. The metal parts of the lifting plate in a humid environment are prone to rust. Anti-rust treatment should be carried out on the equipment every week, such as applying anti-rust grease and checking whether the moisture-proof measures of the electrical system are effective to prevent short circuit faults caused by moisture. In environments with a lot of dust, the dust on the surface and inside the equipment should be cleaned every day to prevent dust accumulation from affecting heat dissipation and the operation of components. The filter screen should be cleaned or replaced every two weeks.

　　The service life of the equipment also needs to be taken into consideration. Newly purchased lifting plates need enhanced maintenance and care during the running-in period (usually 1 to 3 months after use). At this stage, a comprehensive inspection is conducted once a week, closely monitoring the operational status of each component of the equipment, and promptly identifying and resolving potential issues. As the service life increases, the wear of equipment components intensifies. For lifting plates that have been in use for more than five years, the maintenance cycle should be shortened to half of the original. For instance, the original monthly deep maintenance has been adjusted to once every two weeks to promptly identify and replace aged or damaged components, ensuring the safe operation of the equipment. By comprehensively considering factors such as usage frequency, working environment and service life, and formulating a scientific and reasonable maintenance cycle, the service life of the lifting plate can be effectively prolonged, the probability of faults can be reduced, and reliable guarantees can be provided for production and operation.
