ravenna ElectrThe safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
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
ravenna .Lower limit switch: In normal working state, before the suspension cage touches the buffer, the lower limit switch first acts.
When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
.Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, but safety should be maintained.
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, 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 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.
query.Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
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.
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,ravenna Large electric elevator, 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.
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.
resources.Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, small size,ravenna External wall electric elevator, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high, can the folding arm electric elevator provide greater torque output, thereby improving work efficiency. So, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
ravenna .Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width,ravenna Electric mobile elevator, and should not open towards the lifting passage.
The verticality of the guide rail frame should meet the requirements of the specifications.
Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
