In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, stage machinery is particularly important on the stage. On the stage, there are suspension rods, suspension points, lighting bridges, lighting suspension cages, and fire curtains. Under the stage, there are lifting platforms, car platforms, turntables, and lifting orchestras. Some lifting platforms are equipped with turntables, or there are lifting platforms in the turntables. Various types of lifting platforms are equipped in professional opera houses, dance theaters, drama theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery meeting the needs of stage craft layout, meeting the needs of stage design and choreographers, creating special atmosphere and effects, and changing the stage form according to the needs of the performance.
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings,Wieden 1 ton electric elevator, a half height middle crossbar, and a toe board at least 150mm above the ground.
Wieden .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, routine inspections should be carried out according to regulations and inspection records should be filled out.
Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
Electric elevators should be regularly maintained and cleaned. During maintenance and cleaning, the bracket should be supported to prevent the electric elevator from overturning. Electrical and hydraulic systems should be maintained by professional personnel; When the battery level display is less than 40%
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements,Wieden Small car electric elevator, otherwise protective measures shall be taken.
Trustworthy.The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.
Electric elevators used in various places.
The entrance of each landing platform must be equipped with a landing door which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
new product.Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
The installation position of the lower limit switch. The installation position of the lower limit switch should ensure that the contact plate triggers the switch when the rated load of the suspension cage decreases, causing the suspension cage to stop. At this time, using side mounted oil cylinders, stable operation, noise free, easy maintenance, and longer service life.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
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, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, 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.
