Zhang Boli2 meThe 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.
Installation and dismantling personnel and drivers should hold certificates to work.
Zhang Boli.Afterwards, it should be scrapped.
Especially suitable for steel structured factories,Zhang BoliElectric three wheel elevator, suitable for both indoor and outdoor installation.
.When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
Horizontal lead screw mechanical electricity
According to the needs of different performance genres,Zhang BoliElectric cargo 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, or a hall.
Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, strength, etc. and the production should meet the design requirements.
Construction electric elevators must be equipped with lifting cages and reusable buffers, and comply with regulatory requirements.
The L distance depends on the selected wall mount model.
recommend.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,Zhang BoliElectric cargo elevator, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
Setting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.
Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Inspection items.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, an intermediate stage, a T-shaped stage, or a hall.
Before installing the construction electric elevator, the foundation should be inspected and approved before installation.
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, routine inspections should be carried out according to regulations and inspection records should be filled out.
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.
