XinfuElectric 
XinfuElectric 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.
The hydraulic oil forms a certain pressure by the vane pump,XinfuElectric four-wheel elevator, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).

Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, 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,XinfuDC 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 down
.When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N 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.
When the foundation is set on the roof or floor structure the bearing capacity of its supporting structure should be checked.
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
Aluminum alloy lifting platforms can be divided into single column aluminum alloy,XinfuSmall electric winch elevator, cargo elevator, double column aluminum alloy three column and four column aluminum alloy. Can be used in factories, automated warehouses, parking lots, municipal facilities, docks, buildings, and the landing doors should function properly.
Test method.When the landing door is closed, the full width of the lifting passage opening should be covered.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
Word of mouth recommendation.High lifting height, stable operation, noise free, easy maintenance, and longer service life.
Stop the suspension cage.
The 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.
Xinfu.The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.
The net height of the landing door opening should not be less than 8m, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed 35mm, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
