Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination,BolzanoEnnis, shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, smooth lifting and low noise.Bolzano,PoleThe advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.Al Minya,BolzanoDetroit,Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descentSetting requirements: The landing door should be standardized and tooled.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.

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.The upward movement of the hydraulic cylinder involves lifting heavy objects, and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment, and the pressure gauge reads the value when observing the pressure gaugeThe 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.average method,Stage equipment safety door. To prevent personnel from extending their heads hands, its cabin should be full of doors, and the height of the hoistway (hall door) should not be less than meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.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.During 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.

Installation and dismantling personnel and drivers should hold certificates to work.details,Mechanical devices controlled by cage movement should not be used to open or close the landing door.Precautions during operation: Mechanical operations should be gentle and smooth, and mechanical operations should be avoided, otherwise impact loads will inevitably occur, causing frequent mechanical failures and greatly shortening the service life. Generated during homeworkDrainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).Bolzano,Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.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, and standard sections and other components with severe wear and deformation should be replaced.
