LimestoneMobilThe full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
Limestone.When a single steel wire rope is excessively stretched the Electrical safety device shall stop the operation of the electric lift.
From the above comparison, low noise, long service life, large load bearing capacity, and are relatively simple,Limestone6-12 meter fully automatic elevator, making them suitable for use in stage equipment.
.The foundation base or embedded parts should be fully embedded in the concrete foundation plate.
From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform, which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats,LimestoneTricycle electric elevator, etc.
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,LimestoneIndoor small electric elevator, 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.
After the limit switch is activated, only professional personnel can restore the movement of the suspension cage.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
Manufacturing cost.Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
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, the safety distance can be 0.40m.
Total quality assurance.Especially suitable for steel structured factories and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, suitable for both indoor and outdoor installation.
Items and other miscellaneous items.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Limestone.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
Low power consumption: When the hydraulic guide rail lifting platform descends, it is driven by the pressure generated by its own weight, greatly saving energy and reducing consumption.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
