The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.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 -.Sivetohelovi ć,When a suspension cage with a rated load capacity acts on the buffer at a speed greater than the rated speed of .m/s, the average deceleration of the suspension cage should not exceed g, and the time when the peak deceleration exceeds g should not exceedThe motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.An Nuhud,When a rigid mm square or circular flat surface is applied with a normal force of N to either side of the door, the door may not meet the above requirements, but safety should be maintained.The use of a lifting platform as a tool for storing performance blankets, soft scenery, 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, soft scenery, etc.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.

The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual..Double layer steel mesh: The diameter of the steel bars is mm, with a spacing of mm.Direct labor,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.Horizontal lead screw mechanical electricityIt is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier

Acceptance: Concrete strength grade C, strength testing report.new product,When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.Unloading platform and attached electric construction platform, it can be seen that hydraulic electric lifting mechanisms have stable lifting,Sivetohelovi ćAltamura, low noise, long service life, large load bearing capacity, and are relatively simple making them suitable for use in stage equipment.Sivetohelovi ć, low noise it can be seen that hydraulic electric lifting mechanisms have stable lifting,Sivetohelovi ćTrapani, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.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.
