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.
Electric elevators used in various places.
Ludasirenska.The pressure joint between the pipe joint and the rubber hose fails prematurely, causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least 150mm above the ground.
.Setting requirements: The landing door should be standardized and tooled.
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, stability, etc., and the production should meet the design requirements.
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
When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
It is strictly prohibited to use travel limit switches as switches to stop operation.
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
Interpretation and observation.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 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)
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
Speed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor), family dormitories, and
resources.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, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
Construction electric elevators should be equipped with travel limit switches, as follows: automatic reset type upper and lower limit switches should be installed on construction electric elevators,LudasirenskaFlagpole electric elevator, but the upper and lower limit switches should not be triggered as high
From the above comparison, low noise, long service life,LudasirenskaSmall 100kg electric elevator,LudasirenskaMicro electric elevator, large load bearing capacity and are relatively simple, making them suitable for use in stage equipment.
Ludasirenska.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.
The landing door should meet the requirements of the specifications and achieve standardization.
Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.
