Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
Antwerp.The device should be used within the valid calibration period and operate effectively and reliably. The anti fall safety device should have a valid inspection certificate (or inspection report), and the validity period should not exceed 1 year. Anti fall safety devices have been manufactured for five years
The use of a lifting platform as a tool for storing performance blankets, 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, etc.
.Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, 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).
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.
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.
Construction electric elevators should be equipped with safety devices to prevent the cage from falling. The anti fall safety device should be functional at all times, including installation, disassembly, and before resetting after action. Fall arrest safety gear
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.
resources.The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions its calculation sheet, design, and verified by experts.
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.
When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
High lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance, and longer service life.
Pursuit of excellence.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.
Lower limit switch: In normal working state, before the suspension cage touches the buffer, the lower limit switch first acts.
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
Antwerp.Secondly,AntwerpElectric background axis elevator, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation,AntwerpSecond floor electric elevator, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level,AntwerpElectric water gate elevator, timely inspection of various functions is essential.
When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
The net height of the landing door opening should not be less than 8m, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
