The function of a hydraulic lifting platform is to meet the lifting and lowering requirements of goods. Due to its simple structure, convenient operation and control, and reliable operation, hydraulic lifting platforms are gradually replacing mechanical lifts as the main model of lifts. The main function of the proposed hydraulic lifting platform for hydraulic systems is to load the hydraulic bridge according to the conditions. To ensure the safety of work operations, the hydraulic boarding bridge must not have any other overload on the bridge deck during the operation process. When the designated height is reached, loading and unloading operations begin on the bridge deck of the boarding bridge. From this working condition, we can know that the main technical requirements for the hydraulic system of the hydraulic boarding bridge are to ensure that the hydraulic system has sufficient lifting or lifting force to lift the weight of the bridge. Ensure that the hydraulic system has sufficient synchronization accuracy (degree) between the two oil cylinders during the lifting operation. The hydraulic system meets the speed requirements for lifting and repairing during the lifting operation. Detailed analysis was conducted on the working conditions of hydraulic lifting platforms, and based on this, the design calculation basis and hydraulic system principles for such hydraulic lifting platforms were proposed. Before installing the hydraulic lifting platform, all components of the platform should be inspected. Whether all safety devices are complete, and whether the installation position is correct, firm, and reliable; Is there any factor that affects safe operation in the installation environment of the hydraulic lifting platform. The completeness and integrity of metal structures such as guide rails, suspension cages, etc; The assembly accuracy and contact length of gears and speed limiters in the transmission system; Whether the main circuit and control circuit of electrical equipment (sh è b è i) comply with the national product standards; Whether the basic position and method meet the design requirements of the product; Whether the concrete strength and bolt holes at the location where the wall bracket is installed meet the installation conditions; Is the action of each limit switch sensitive. ?
