The verticality of the guide rail frame should meet the requirements of the specifications.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,BrunswickXie Deze, the door should be able to withstand and have no deformation; - Deformation not exceeding mm; After the test, it worked normally.Brunswick,The movement of its related components is direct.From the above comparison, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.Missungwi,During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed mm.Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed ohms; The power supply of the electric elevator can be cut off.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, 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.

Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.Steel wire rope construction electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices, which should have compliant loosening rope switches and be able to interrupt any movement of the lifting cage until it is approved by a professionalWhen the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.High quality and low price,The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than .m; If the rated speed is not greater than .m/s, the safety distance can be .m.The counterweight guide rail should meet the specification requirements.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.

When the wall bracket adopts non matching standard products, design calculations should be carried out.management,When the landing door is closed, the full width of the lifting passage opening should be covered.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 %The motor of the hydraulic guide rail lifting platform is set around the wellbore, improving the utilization rate of the wellbore area.Brunswick occupying a relatively small area,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, hydraulic control one-way 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,BrunswickOsnabluk,BrunswickStockton, 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 verticality of the guide rail frame should meet the requirements of the specifications.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.
