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.
According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, then falls, and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.

Low failure rate: Due to the use of advanced hydraulic systems and good methods, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.
Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.

Check the wear condition of the pinion and rack, please refer to the instruction manual for specific requirements
The second method is the protective layer method, which covers the metal surface of the aluminum alloy lifting platform with a protective layer to isolate the metal products from the surrounding corrosive medium and prevent corrosion. Apply engine oil, petroleum jelly, paint, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; Using electroplating, hot plating, spray plating, etc., to coat the surface of steel with a layer that is not easily corroded

During aging treatment, the front end of the a-t curve shows an upward trend, so the amplitude gradually increases; Since then, the amplitude change has been basically stable, indicating that the structure of molecules inside the component tends to be stable, which conforms to the judgment standard of curve observation strip, thus it can be determined that the workpiece has reached the effect. The precautions for using an electric lifting platform are as follows: the user unit should arrange a dedicated person to operate the lifting platform and develop details and safety precautions for the use of the lifting platform based on their own unit's situation, and hang it in a prominent position. When working on an electric lifting platform, professional drivers and operators must be equipped, and they must undergo specialized training and be qualified. They must hold relevant certificates and take on corresponding responsibilities according to the actual situation of the work. After the construction is completed, the lifting platform needs to be moved on the site and should be operated by a professional driver. Before daily work, zy12 drivers must carefully check the electrical, hydraulic, and mechanical systems of the platform,ChinstohovaTraction lifting platform, check the working range of the lifting platform truck, and remove obstacles that hinder the rotation and walking of the lifting platform truck. And empty the platform up and down several times to check for any faults or abnormal phenomena. It is also necessary to pay attention to the accuracy of the platform platform landing station for any obvious abnormal differences.
