Jinghai22ov elPipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
Horizontal lead screw mechanical electricity
Jinghai.Before each shift of work, the safety devices of the construction electric elevator should be inspected to ensure sensitivity and reliability.
Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.
.Setting requirements: The landing door should be standardized and tooled.
Spiral electric lifting mechanism: With all the functions of a regular lifting platform, the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only 200-500mm and a travel distance of up to 14m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.
The counterweight guide rail should meet the specification requirements.
When the landing door is closed,JinghaiMobile electric elevator, the full width of the lifting passage opening should be covered.
The impact load can cause early wear, fracture, and fragmentation of mechanical structural components, as well as generate impact pressure in the hydraulic system, which in turn can damage hydraulic components, oil seals, and high-pressure oil
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
resources.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.
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
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.
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,JinghaiLEGO Electric Elevator, using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage,JinghaiElectric curved arm elevator, a T-shaped stage, or a hall.

We have all purchased the aluminum alloy electric elevator equipment, hospitals, airports, and large parking lots also wear this equipment
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
Jinghai.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
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.
Setting requirements: The installation and dismantling workers, electricians
