TiheiElectric 
TiheiElectric Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
The L distance depends on the selected wall mount model.
Tihei.Limit switches should be triggered directly by the movement of the suspension cage or its related components.
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures the side protection device for the landing entrance should be equipped.
.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
Setting requirements: The landing door should be standardized and tooled.
Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
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 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,TiheiSmall electric winch elevator, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve, hydraulic control one-way valve, energy-saving valve, 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.
Sales Department.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,TiheiElectric screw elevator, 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,TiheiElectric brick elevator, 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.
During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, 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 150mm.
When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
Online consultation.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.
The coaxiality between the motor shaft and the worm shaft in the aluminum alloy electric elevator drive device should be less than 0.1mm, and the landing doors should function properly.
Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door
When the landing door is closed, the full width of the lifting passage opening should be covered.
