During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise, measures should be taken to make it meet the requirements,DalasDodhurt, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed mm.Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).Dalas,.Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width, and should not open towards the lifting passage.Senlar,Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.There is no need to set up a computer room above the shaft like an elevator, suitable for both indoor and outdoor installation.Is there a relevant rule requirement for the cleanliness of hydraulic stations?Installation verticality deviation guide rail frame erection height, h/mH≤ H& gt; verticality deviation/mm≤ (/h≤ ≤ ≤ ≤ pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (/) h.For more, please check,To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve,DalasDelft, 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 SB&flash; The rotation of the SB 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.The function of the lifting platform in a theater is roughly as follows: the main lifting platform arranged in the main performance area of the stage is mainly used to quickly change the scenery. Typically, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform,DalasKassel, and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.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.

The hydraulic oil forms a certain pressure by the vane pump, explosion-proof electromagnetic directional 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).Executive standard,Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around -mm, and the top layer is not affected. It can be customized according to the location and environment.The down travel (limit) switch should be of the automatic reset type.When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.DalasSetting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor positionTank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
