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.
Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
New Songqi.Check and repair the electrical circuit and control panel switch components. If there is aging in the circuit, replace it
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, 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, while the lifting foundation structure has a large volume and does not have a large enough annealing furnace. Using natural aging takes one year and the production cycle is too long, so neither of these two methods is feasible. After research and understanding by the manufacturer, it was found that selecting appropriate support points for large welded structural components can perform vibration aging stress relief. Therefore, the manufacturer has decided to use vibration aging for stress relief of the platform lifting foundation.

Check if the usage period of the speed limiter has expired. If it exceeds the usage period, it is necessary to send it to a qualified professional unit for inspection and calibration. What are the functions of the lifting stage device?
The selection of vibration pickup points refers to the placement point of the sensor, which is used to measure the vibration amplitude of the workpiece. According to GB/T25712-2010, the acceleration sensor should be placed on the workpiece with a certain rigidity and a large amplitude, and its testing direction should be adjusted to be perpendicular to the plane where the effective zone of the vibration mode is located. Considering the complex structure of the lifting foundation workpiece and the uneven thickness of each component, the vibration pickup point is set in a thick area in the middle of the component.
Inspection environment.According to GB/T25712-2010,New SongqiSelf walking scissor type high-altitude lifting platform, 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, 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.
When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.
Jinchuang lifting platform product feature 01 is mainly used for high-altitude cargo transportation between floors. With a load capacity of 1-50 tons and a lifting height of 1-25 meters, a guide rail elevator, also known as a hydraulic elevator, can be installed indoors and outdoors. The lifting height is high and uses a side mounted oil cylinder, which runs smoothly, has low noise, is convenient for maintenance and has a long service life. In case of a power outage, manual emergency descent can be used, which is safe, convenient, fast, and the top layer height is not affected, The 04 pump station can be customized according to the on-site environment, suitable for 2-3 floors of steel structures or concrete factories. Both the internal and external parts can be used. The 05 pump station adopts a joint venture pump station and an imported pump station from Italy. If the speed requirement is too high,New SongqiCar mounted aluminum alloy elevator, a joint venture customized pump station can be used to meet the ideal delivery requirements. The 06 oil cylinder and seals are made of imported components, solving the problem of unstable oil pressure for customers, The oil leakage problem of components 07. The oil cylinder is built into the platform 08. The heavy-duty steel wire rope wheel or weighted special chain ensures safety 09. The automatic insurance during the lifting process ensures vehicle safety 10. The synchronous device during the lifting process ensures that the vehicle may not overturn 11. The alarm setting before falling to the ground ensures the safety of the operator 12. The chain or steel wire rope fracture protection device 13. The hydraulic system pressure loss prevention protection device 14. The elevator special flat layer permanent magnet switch is selected,New SongqiMobile scissor fork lifting platform, The leveling effect is good. 15. The distance between heavy and empty loads is small, and the leveling accuracy is high. 16. Standard elevator boards, LCD display call boxes, relevant wiring harnesses, and connectors are selected. Beautiful appearance easy operation, visual display of the position of the elevator car on the floor, wiring harness connected using connectors, with automatic and manual options.

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, it is necessary to perform stress relief treatment on the completed components.
