Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.The use of fully autonomous electric elevators can create more benefits and ensure safety in all aspects.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 downVariable costDuring loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed mm.Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design.
