When the door is closed, except for the gap between the lower part of the door that should not exceed mm, 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 of GB -.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 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.Hungary,The upward movement of the hydraulic cylinder involves lifting heavy objects, and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment, and the pressure gauge reads the value when observing the pressure gaugeThe safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.Santiago-Sacatepequez,When the landing door is closed, the full width of the lifting passage opening should be covered.Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descentUse floor doors and cage door devices on construction sites where conditions permit.

The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.Setting requirements: Construction electric elevators should be equipped with up travel (limit) switches.When the wall bracket adopts non matching standard products, design calculations should be carried out.Quotation sheet,Small safe operation distance: Circuit voltage (kV) of external power lines<~~~ Small safe operation distance (m) Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.Safety performance: Electric elevators not only have the safety device of traditional traction elevators,HungaryViti sur Seine, but also have an overflow valve to prevent excessive system pressure during upward movement

Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.High value, in addition to lighting and sound,HungaryRouen, stage machinery is particularly important on the stage. On the stage, there are suspension rods, suspension points, 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.After the limit switch is activated, only professional personnel can restore the movement of the suspension cage; Limit switches and travel switches should not share the same triggering element; Limit switches should be either suspended orThe full height landing door should meet the following requirements: the net height of the landing door opening should not be less than m. In special circumstances when the net height of the building entrance is less than m, but in any case it is allowed to lower the height of the lower door opening, the net height of the lower door opening is not less than m. (Article of GB-)Hungary,The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.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, or there are lifting platforms in the turntables. Various types of lifting platforms are equipped in professional opera houses, drama theaters,HungaryCincinnati, 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.
