Brussels.8m； When the lifting speed is greater than 0.8m/s,BrusselsFixed electric elevator,BrusselsAutomatic electric elevator, after the upper limit switch is triggered by the hanging cage, the upper small safety distance L should meet the following requirements: L=8+0.1V2, where L is the upper safety distance; V: Increase speed
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
.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
When 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.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
The installation position of the lower limit switch. The installation position of the lower limit switch should ensure that the contact plate triggers the switch when the rated load of the suspension cage decreases, causing the suspension cage to stop. At this time, the contact plate should also be close to the triggering of the lower limit switch
The landing door should meet the requirements of the specifications and achieve standardization.
Quality recommendation.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
The landing door should meet the requirements of the specifications and achieve standardization.
When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
Quality inspection report.There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least 2.5 meters.
The downward movement of the hydraulic cylinder (i.e. heavy object lowering). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, hydraulic control one-way valve, energy-saving valve, and explosion-proof electric valve
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, throttle valve,BrusselsElectric small elevator, hydraulic control one-way valve, and balance valve causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
Brussels.In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, 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.
Later, when there is a major malfunction of the lifting platform, it should not be used again to avoid accidents, personnel and property losses.
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.
