TaiwanSmall elSecondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, and ensure that the lifting platform can be lifted to the rated lifting height.
Protective measures should comply with regulatory requirements.
Taiwan.Construction electric elevators should be equipped with safety devices to prevent the cage from falling. The anti fall safety device should be functional at all times, including installation, disassembly, and before resetting after action. Fall arrest safety gear
Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.
.It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier
Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.
According to the needs of different performance genres, the form of the stage can be changed. For example, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, using a lift can make the theater have various forms such as an end stage, an island stage, an intermediate stage, a T-shaped stage, or a hall.
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
The shutdown device (emergency stop switch) should be non automatic reset type.
The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
Job description.Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform, which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats, etc.
market price.Monthly maintenance and inspection of hydraulic lifting platform rollers intermediate shafts and bearings, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, or has foreign objects such as gravel sticky, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
The impact load can cause early wear,TaiwanElectric elevator battery, fracture, and fragmentation of mechanical structural components, as well as generate impact pressure in the hydraulic system, which in turn can damage hydraulic components oil seals, and high-pressure oil
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator,TaiwanElectric mobile elevator, with a size of 8 meters by 2 meters.
Taiwan.Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
