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,BessabaSelf walking scissor type high-altitude lifting platform, 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.
.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 stop: Press the emergency button switch to raise or lower the machine.
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,BessabaAluminum alloy hydraulic lifting platform, it is advisable to use or 4-point support.
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, we set the vibration points on the protruding plates on each side of the workpiece.
Use a feeler gauge to check the wear condition of the worm gear of the worm gear reducer. Please refer to the instruction manual for specific requirements
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, which greatly saves energy.
Lets see.Outbound call form: Outbound call boxes are pre embedded or installed in a column style on the wall or ground near the parking floor above and below the platform, and are linked to operate the platform up and down.
Whether the vibration aging treatment has achieved the results can be judged based on the parameter curve observation method.
Emergency stop: Press the emergency button switch to raise or lower the machine.

Regarding the construction elevator with counterweight, check the adjustment and fixation status of the counterweight guide wheel. Check the balancing equipment of the steel wire rope, the crown wheel, and the counterweight steel wire rope bracket
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,BessabaGuide rail vertical lifting platform, so 5366r/min was determined as the aging frequency.

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, and the structure is complex. Therefore, two support points should be taken on each side for time treatment.
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.
