EmerodFully el
Emerod6-12 metThe 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, 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.
The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
Emerod.Unloading platform and attached electric construction platform, etc.
The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing,EmerodElectric four-wheel elevator, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design,EmerodMicro electric elevator, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
.When the wall bracket adopts non matching standard products, design calculations should be carried out.
The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
When adding hydraulic oil, we can extend the oil cylinder to the high position for filling. When filling, the lifting platform should not exceed the high position, and then retract the oil cylinder back to the low position to check if the hydraulic oil level is lower than the low position, and maintain it between the two.
The verticality of the guide rail frame should meet the requirements of the specifications.
The cheapest.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
Implementing multiple shifts of homework should fill in and submit records according to regulations.
Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
property right.The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
Precautions for safe use of electric elevators: Before use, remove any obstacles or debris near the electric elevator that may hinder operation,EmerodSmall electric screw elevator, and check whether the operating handle can be used normally.
Horizontal lead screw mechanical electricity
Emerod.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.
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 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 island stage, an intermediate stage, a T-shaped stage
