The lifting foundation of the platform is a large structural component made of alloy steel plates with different thicknesses that are welded together. The welding amount is large, the structural shape is complex, and residual stress is inevitably generated during the manufacturing process. In order to prevent deformation of the components due to changes in residual stress during use, and are linked to operate the platform up and down.

The safety control voltage of 18 is selected with rolling guide shoes, high accuracy, wear resistance, and stable lifting. The characteristics of the Jinchuang lifting platform are as follows: 1. There is no need for a machine room above the shaft. 2. The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area. 3. The load and load cylinder of the hydraulic elevator directly act on the foundation pit, and the strength requirements of the shaft are low, Brick or brick concrete structure hoistway can be used for Jinchuang lifting platform safety and stability advantages. Overflow valve: It can prevent system pressure from being too high during upward movement. Emergency manual valve: In case of power failure, it can make the elevator emergency descend to the nearest floor position and open the door.
Check the oil level of the gearbox and make up for new oil if necessary
The vibration frequency should be set to obtain large dynamic stress with low energy consumption, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components and using resonance peaks with higher peaks and lower frequencies for aging can achieve optimal results. The resonance frequency needs to be determined by trial vibration, which slowly increases the speed of the excitation motor from 0, and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.

The wear rate is fast, and due to factors such as processing, assembly, and adjustment of new machine components, the friction surface is rough, the mating surface area is small, and the surface pressure condition is uneven. During the operation of the machine, the concave and convex parts on the surface of the parts are intertwined and rubbed against each other. The metal debris that falls off from the grinding process, in turn, during the running-in period further accelerating the wear of the mating surface of the parts. Therefore, it is easy to cause wear on components (especially the mating surface), with a fast wear rate. At this point, if overloaded, it may cause damage to the components and lead to early failures.
