The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than m. In special circumstances, when the net height of the building entrance is less than m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than m. (Article of GB-)When the wall bracket adopts non matching standard products,qinghuangdaoSan Antonio, design calculations should be carried out.qinghuangdao,The use of fully autonomous electric elevators can create more benefits and ensure safety in all aspects.Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.Sinjah,The use of standard section connecting bolts should comply with the user manual and specification requirements.Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, which is better than stacking them in the center of the cargo stacking area of the cargo elevator to avoid imbalance between the two ends of the stacking area. Eventually, during the operation of the electric elevator, it may cause the electric elevator to lose balance. After the goods are stacked completely, ropes should be used to lock the goods, so that they are not afraid of the goods during the lifting process; Careless; Scattered downThe distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.

Protective measures should comply with regulatory requirements.Limit switches should be triggered directly by the movement of the suspension cage or its related components.Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion, Terrace, Tower, Pavilion; Ideal props.Production department,According to the needs of different performance genres,qinghuangdaoHejin, 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.When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.Setting 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.Superior quality,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.Precautions during operation: Mechanical operations should be gentle and smooth, and mechanical operations should be avoided,qinghuangdaoMesa, otherwise impact loads will inevitably occur, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.qinghuangdaoPrinciple of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a degree position until it is closed and then turn the transmission handwheel to lower the plug and achieve sealing.When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.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.
