Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.

Drivers should be responsible for supervising the uniform distribution of items transported by the platform on the platform as much as possible to prevent partial loading and prohibit overloading. flat

Larosh on the Yonghe River.Leakage occurs due to looseness, vibration, and the influence of heat on the sealing surface and pipe joints of the machine; Some casting, processing and other defects are difficult to detect during assembly and debugging, but due to vibration and impact during the operation process, these defects are exposed, manifested as oil (water) leakage. Therefore,Larosh on the Yonghe RiverRail type cargo lifting platform, leakage is prone to occur during the running-in period. Poor, due to the small fit clearance of newly assembled components and the difficulty in ensuring the uniformity of fit clearance due to assembly and other reasons,Larosh on the Yonghe RiverAluminum alloy lifting platform single column, oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. This reduces efficiency and causes early abnormal wear of the components. In severe cases, leading to the occurrence of faults.

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.

.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.

Emergency stop: Press the emergency button switch to raise or lower the machine.

On the contrary, it should be adjusted in the opposite direction; When the meshing backlash of the gear pair is greater than 0.5mm, loosen the connecting nut of the eccentric shaft of the guide roller 4 and the tooth back pressure wheel as shown in 2, adjust the tooth back pressure wheel to press towards the back plane of the gear rack until the backlash reaches a reasonable range. Otherwise, it should be adjusted in the opposite direction. At this point, the guide roller should be loosened for 2 o and then adjusted according to the adjustment of the guide roller.

Emergency stop: Press the emergency button switch to raise or lower the machine.

Product line.The safety control voltage of 18 is selected with rolling guide shoes, 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.

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.

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,Larosh on the Yonghe RiverHydraulic aluminum alloy lifting platform, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.

Where to sell API.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.

The cleaning oil for the hydraulic system must use hydraulic oil of the same brand as the system used, with an oil temperature between 45 and 80 ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more. After each cleaning, the failure rate of elevator operation can be minimized. Low power consumption: When the hydraulic elevator descends, 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.
