LangfangMaintenance of aluminum alloy hydraulic lifting platformWhat are the contents of the test

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?

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.

Langfang.Check the wear and clearance condition of the guide wheel of the cargo elevator

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.

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

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 with price advantages and guaranteed quality!

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

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,LangfangScissor fork mobile hydraulic lifting platform,LangfangGuide rail type lifting platform, 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.

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

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

Energy costs.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.

The second method is the protective layer method, which covers the metal surface of the aluminum alloy lifting platform with a protective layer to isolate the metal products from the surrounding corrosive medium and prevent corrosion. Apply engine oil,LangfangCar mounted scissor fork lifting platform, petroleum jelly, paint, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; Using electroplating, hot plating, spray plating, etc., 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?

Check if the orientation of the upper and lower limit blocks on the guide rail frame is correct

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

Langfang.According to GB/T25712-2010, 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.

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?

The driver shall close and lock the movable doors at both ends of the protective fence before work, and then ring the bell to start. It is strictly prohibited to work with the movable doors of the protective fence open. In case of special circumstances during platform operation, the emergency stop switch can be used to stop the platform. However during normal operation
