AbundantElectrWhen the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
Abundant.Precautions for safe use of electric elevators: Before use, remove any obstacles or debris near the electric elevator that may hinder operation, and check whether the operating handle can be used normally.
In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound,AbundantLadder type electric elevator, stage machinery is particularly important on the stage. On the stage, there are suspension rods, suspension points, lighting bridges, lighting suspension cages, and fire curtains. Under the stage, there are lifting platforms, car platforms, turntables, and lifting orchestras. Some lifting platforms are equipped with turntables, or there are lifting platforms in the turntables. Various types of lifting platforms are equipped in professional opera houses, dance theaters, drama theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery, meeting the needs of stage craft layout, meeting the needs of stage design and choreographers, creating special atmosphere and effects and changing the stage form according to the needs of the performance.
.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 outside the lightning protection range
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.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
When a suspension cage with a rated load capacity acts on the buffer at a speed greater than the rated speed of 0.2m/s, the average deceleration of the suspension cage should not exceed 1g, and the time when the peak deceleration exceeds 5g should not exceed
The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
Setting requirements: The landing door should be standardized and tooled.
Quality assurance.The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, soft scenery, etc.
The working principle of the aluminum alloy lifting platform is that hydraulic oil is composed of a vane pump to form a certain pressure, explosion-proof electromagnetic directional valve,AbundantElectric single arm elevator, throttle valve, hydraulic control one-way valve, and balance valve
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Abundant.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 landing door shall not be opened.
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 the safety distance can be 0.40m.
