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.
Baoding.Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
Construction electric elevators outside the lightning protection range
.To meet the needs of stage craftsmanship and layout; Product; In the music and dance theater stage arranged in a zigzag pattern, auxiliary lifting platforms are often arranged in front, left, and right of the main stage lifting platform. The side and rear auxiliary lifting platforms are used for the smooth opening of the side platform and rear vehicle turntable, while the front auxiliary lifting platform is used to place the rear vehicle turntable near the platform entrance. The leveling lifting platform below the side platform and rear vehicle turntable can be used to level the platform after the side platform or rear vehicle turntable is driven out, so that the entire platform does not have a height difference, ensuring the safety of the cast members.
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
Fully autonomous lifting is widely used in various high-altitude work fields, such as factory maintenance,Baoding8 meter electric elevator, airport maintenance, street light maintenance, and so on; How to use electric elevators correctly to extend the service life of the equipment and be flexible
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Test conclusion.Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, which should cover the opening with its full width and should not open towards the lifting passage.
The cheapest.It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, which should have compliant loosening rope switches and be able to interrupt any movement of the lifting cage until it is approved by a professional
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 making high-altitude operations easier
Steel wire rope construction electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices, 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.
Baoding.When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures,Baoding500kg electric elevator, the side protection device for the landing entrance should be equipped.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.
