The improvement of the quality of high-altitude work vehicles by loading and unloading platforms has played a driving role

  & nbsp; Before operating the loading and unloading platform of the device, the oil tank, pipelines, hydraulic cylinders, valves, etc. must be cleaned. The new oil filled into the oil tank must be filtered with an oil filter to avoid oil contamination caused by unclean oil drums. After one week of use, the temperature of the hydraulic oil in the new pump station should not exceed 82 ° C. The oil should be filtered once, and then the hydraulic oil should be replaced and the oil tank cleaned every 3-6 months according to the working environment and frequency of use of the elevator.



  & nbsp; When used in hydraulic circuits, it is necessary for the hydraulic pump to have a certain degree of self-priming ability. The occurrence of cavitation may not only damage the hydraulic pump, but also cause a sensation and noise, resulting in poor operation of the control valve components, which can have a negative impact on the entire hydraulic system of the hydraulic elevator.

  & nbsp; The manufacturer of the loading and unloading platform is a manned operation machinery, and reliability is very important, especially for the emergency suspension system, which is related to many links. After changing to power-off suspension, which link has problems can be detected and dealt with in a timely manner. This method can promote the improvement of weak links in planning, technology, and production, and will have a promoting effect on improving the product quality of high-altitude operation vehicles.

  & nbsp; Gasoline engines can be shut down by blocking the combustion power source, which is relatively simple and reliable. Diesel engines are generally shut down by blocking fuel supply, blocking cylinder suction, and other methods, which require mechanical displacement of the organization to complete. There are various types of this organization, but due to the remote control feature in the channel and the need for a central reverse joint, the mechanic's shutdown organization cannot be used.
