HildesheimCar Outdoor guide rail lifting platform, mainly used for high-altitude cargo transportation between floors. With a load capacity of 1-50 tons and an elevation of 1-25 meters, guide rail elevators also known as hydraulic elevators, can be installed indoors and outdoors. They have a high lifting height and use side mounted oil cylinders, ensuring smooth operation, low noise, and long service life. In case of power failure, which is safe, convenient, fast, and practical. The pit depth is generally 15cm-30cm. Professional elevator manufacturers have high pressure resistance, good waterproof performance, and fire and high temperature resistance,HildesheimSelf propelled lifting platform, Strong overload capacity, corrosion resistance, radiation resistance, long service life. The top layer height is not affected, and can be customized according to the on-site environment. It is suitable for 2-3 story steel structures or concrete factories, and can be used both internally and externally.
The arrangement of vibration points should be based on the vibration aging process standard GB/T25712-20. The vibration aging exciter should be placed at a position with high rigidity and amplitude of the workpiece, and its rotating axis should be parallel to the plane where the effective zone of the vibration mode is located. The exciter should be fixed at the end angle or edge of the workpiece with high rigidity so that small energy can be used to excite the component with large amplitude. Based on the structural shape of the foundation,HildesheimStage style lifting platform, we set the vibration points on the protruding plates on each side of the workpiece.
Hildesheim.The surface of each part of the brush should be kept clean, 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.
.However, large welded structural components have the characteristics of complex morphology, large weight, large differences in residual stress size and distribution, and it is difficult to achieve good results using ordinary vibration aging technology. Therefore, it is crucial to develop a reasonable process. Therefore, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.
Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.
The design of support points for selecting process parameters is to avoid energy consumption and noise generation due to collision between components and supports during vibration. The supports should be arranged near the nodal line and the layout principle is: when the aspect ratio of the component is greater than 2, two point supports can be used; When the aspect ratio is close to 1, it is advisable to use or 4-point support.
Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.
Check the clearance of the ball bearing and the wear of the suspension wheel guide wheel. If the roller is worn, it is necessary to adjust or replace it. If the elevator bearing is worn, replace the guide wheel or bearing
Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
Standard requirements.The safety control voltage of 18 is selected with rolling guide shoes, high accuracy, wear resistance, and stable lifting.

Now with the arrival of summer, the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?

discount.Vibration aging treatment and effect judgment: According to the aging process plan, after setting the support points and vibration pickup points of the workpiece, use a rigid fixture to fix the exciter on the workpiece, so the excitation force is selected as the fourth gear.
Check and clean the driving gears and guide wheels of the elevator. If there is excessive wear, it is necessary to replace them
According to calculations, when the support points of the beam type components are located along the length of 1/9L on both sides the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component,HildesheimSelf folding arm lifting platform, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.
Hildesheim.Emergency descent: Handle operation or use of manual pressure relief and activation of emergency battery system to implement emergency descent function safety net.
According to GB/T25712-2010, when one of the following situations occurs in the curve related to the aging frequency, it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises, then falls, when the support points of the beam type components are located along the length of 1/9L on both sides, the vibration resistance is relatively small, making it easy to obtain resonance and vibration effects with larger amplitudes. The geometric shape of the structure on the lifting foundation is similar to a long beam type component, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.
