Product Details

Driving principles:


The screw elevator uses an electric motor as a power source. The motor is connected to the nut by a belt which is meshed with the helical tooth. When the motor is working, the drive nut moves on the screw, thereby driving the platform to move up and down.

Figure 2: The motor is connected to the nut by a belt that engages the helical teeth.



Figure 3: When the motor is running, the drive nut moves over the screw, causing the drive platform to move up and down.

[safety protection]


The safety is higher. In fact, there is always something to hold underneath. Even if the power is lost, the free fall will fall. The screw will also drive the motor to do a large negative work. The drop will be very slow, so the elevator will not fall, and As long as the screw is locked, the free fall can be prevented from falling.

Fire adopts UPS power failure emergency leveling--no power failure
