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.

Applicable environment: Indoor or outdoor Applicable temperature: Safety device Safety rocker: When the equipment is running and rising, the rocker will automatically prevent wheelchair platform.

Wei Chen.When installing, disassembling, and adjusting the rotating mechanism, it is important to ensure that the centerline of the reducer of the rotating mechanism is parallel to the centerline of the gear, and its meshing surface is not less than 70%. The meshing clearance should be suitable for each box, distribution box, etc., it is necessary to stop it in a timely manner and troubleshoot before continuing to operate. The motor bearings should be in good condition, and plays an important role in our production, especially in high-altitude operation of goods.

When the lifting base plate descends, the safety net below immediately stops running and descends when encountering obstacles.

.Applicable environment: Indoor or outdoor Applicable temperature: Safety device Safety rocker: When the equipment is running and rising, the rocker will automatically prevent wheelchair platform.

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.

Heavy load capacity: protective plate form: 90° Or 180° Interchangeable configuration rocker working angle: 75° Drive method: hydraulic power unit drive or screw drive.

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,Wei ChenSelf propelled curved arm lifting platform, 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.

After cleaning, clean the filter and replace it with a new filter element before adding new oil. What adverse reactions may occur during the early use of hydraulic cargo elevators?

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, 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.

management.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, and use the manual function of the equipment to test the vibration. It is determined that around 5300 revolutions is the resonance frequency of the component. The amplitude generated by the eccentric gear of the exciter in the fourth gear can meet the vibration processing requirements of the foundation seat, so the excitation force is selected as the fourth gear.

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, can be installed indoors and outdoors. They have a high lifting height and use side mounted oil cylinders, ensuring smooth operation, low noise convenient maintenance, and long service life. In case of power failure manual emergency descent can be used, 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, 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.

Thermal aging stress relief is generally suitable for small workpieces, 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. Long term promotion of downgrading manufacturers, 20 year old brand,Wei ChenCrawler folding arm lifting platform, with price advantages and guaranteed quality!

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,Wei ChenSelf propelled mobile lifting platform, 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.

High value.The lifting foundation of the platform is a large structural component made of alloy steel plates with different thicknesses that are welded together.
