The L distance depends on the selected wall mount model.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, turntables car platforms,MarsonSligo, 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,MarsonEnnis, 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.Marson,And prevent it from starting normally. There should be no device that allows users to cancel warning signals.The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of meters by meters.Baladro,The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.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, creating unexpected atmosphere and effects according to the needs of the plot. For example, 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.

The list of materials for making landing doors is as follows: Table : List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.The up travel (limit) switch should be of the automatic reset type.When applying a normal force of N to any position on either side of the door using a rigid mm square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding mm; After the test, it worked normally.Analysis project,Mechanical devices controlled by cage movement should not be used to open or close the landing door.When applying a normal force of N to any position on either side of the door using a rigid mm square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding mm; After the test, it worked normally.Emergency manual valve: In case of power failure,Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion, Terrace, Tower, Pavilion; Ideal props.Precautions for safe use of electric elevators: Before use, remove any obstacles or debris near the electric elevator that may hinder operation,MarsonQigaiqi, and check whether the operating handle can be used normally.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 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.Marson,The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.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
