Installation and dismantling personnel and drivers should hold certificates to work.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
cork.The usual operation of landing and docking. The installation position of the upper limit switch should comply with the following: when the lifting speed is less than 0.8m/s, the upper safety distance L left after the upper limit switch is triggered by the hanging cage should not be less than
It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier
.The 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.
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, stability,corkMicro electric hoist, etc. and the production should meet the design requirements.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements,cork6-12 meter fully automatic elevator, otherwise protective measures shall be taken.
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,corkSmall electric screw elevator, the protective measures taken should comply with the specification requirements.
When adding hydraulic oil, it is also necessary to pay attention to the structure of the oil cylinder. Some oil cylinders are relatively complex internally, and how many lifting operations need to be carried out during filling to fully fill each position of the hydraulic oil. Therefore, when filling, try to add as much as possible, and then test and run the machine empty to see if it reaches the rated position.
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.
Management Department.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, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform, and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.
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, and then turn the transmission handwheel to lower the plug and achieve sealing.
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, the side protection device for the landing entrance should be equipped.
Total quality assurance.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), which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places, family dormitories, and
The movement of its related components is direct.
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.
cork.Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.
To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
