From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise,ChifengMeis, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.The landing door should meet the requirements of the specifications and achieve standardization.Chifeng,. The shutdown device (emergency stop switch) should be installed outside the ground protective fence; b) Pulley room (if any. Pulley room refers to a room where only pulleys or speed limiters and electrical equipment are installed; c) hanging cage top, ifDuring normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed mm.Solola,Mechanical devices controlled by cage movement should not be used to open or close the landing door.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/T; Maintenance, wear, and corrosion of steel wire ropesProtective measures should comply with regulatory requirements.

Mechanical devices controlled by cage movement should not be used to open or close the landing door.During maintenance or when problems occur, the aluminum alloy electric elevator should be firmly fixed before maintenance can be carried out. It is strictly prohibited to operate with defects to avoid accidents.After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit, and supervision unit to conduct acceptance. For the implementation of construction general contracting, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.project,ChifengMannheim,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.Before operating the construction electric elevator routine inspections should be carried out according to regulations and inspection records should be filled out.Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.

High lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance, and longer service life.technical service,ChifengPotisi,High lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance, and longer service life.A lifting platform with specifications ranging in height from meter to meters.According to the needs of different performance genres, the form of the stage can be changed. For example, using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage, a T-shaped stage, or a hall.Chifeng,Before operating the construction electric elevator routine inspections should be carried out according to regulations and inspection records should be filled out.Small safe operation distance: Circuit voltage (kV) of external power lines<~~~ Small safe operation distance (m) Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.
