The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve,LudasirenskaElectric bed elevator, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
Later, when there is a major malfunction of the lifting platform, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, personnel and property losses.
Ludasirenska.Before each shift of work, the safety devices of the construction electric elevator should be inspected to ensure sensitivity and reliability.
The quality of the standard section should comply with the product manual and specification requirements.
.Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
From the above comparison it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, and a toe board at least 150mm above the ground.
Setting requirements: The installation and dismantling workers, electricians, and do not lift until the four legs are firmly supported.
Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.
Inspection basis.Use floor doors and cage door devices on construction sites where conditions permit.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
According to the needs of different performance genres, 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,Ludasirenska2 ton electric elevator, an island stage, an intermediate stage, a T-shaped stage, or a hall.
Create brilliance.The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
When using lifting equipment, the workbench should be kept in a horizontal state.
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve,LudasirenskaElectric scissor type lifting platform, throttle valve, hydraulic control one-way valve, and balance 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).
Ludasirenska.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.
Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.
Implementing multiple shifts of homework should fill in and submit records according to regulations.
