it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking

Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.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.Henan,m； When the lifting speed is greater than .m/s, after the upper limit switch is triggered by the hanging cage, the upper small safety distance L should meet the following requirements: L=+.V, where L is the upper safety distance; V: Increase speedTo ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB&flash; The rotation of the SB motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.Kilifi,Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.Work is essential, and the main protective accessories include safety belts, guardrails, protective covers platforms and stairs, etc.

When the door is closed, except for the gap between the lower part of the door that should not exceed mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, should comply with the provisions of Table of GB -.Is the water cooling and air cooling of the hydraulic station the same?Electric elevators used in various places.Application process,The use of a lifting platform as a tool for storing performance blankets, soft scenery,HenanMassara, etc. In some theaters, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, etc.Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset,HenanLv Liang, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.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.

To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB&flash; The rotation of the SB motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.Customer first,The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve,HenanIrish Root, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).The water cooling of hydraulic stations is generally tubular water cooling. The selection is based on the heat load to calculate the heat exchange area, while the air-cooled electric elevator uses an air cooler to calculate the heat exchange capacity based on the heat load. Then, the selection calculation is carried out under the condition of satisfying the flow rate. So, these two types of cooling are different and have significant differences.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 extended stage, an intermediate stage, a T-shaped stage, or a hall.Henan,When the door is closed, except for the gap between the lower part of the door that should not exceed mm, as well as the gap around the door or the gap between parts, should comply with the provisions of Table of GB -.Use floor doors and cage door devices on construction sites where conditions permit.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
