How does the hospital elevator work?

The hospital elevator is an elevator designed to transport hospital beds, stretchers, and medical vehicles. The car has the characteristics of long and narrow. A vertical elevator powered by an electric motor is equipped with a box-shaped pod. Fixed lifting equipment serving the specified floors. It has a car that runs between at least two rows of vertical rigid guide rails.

The working principle of the medical elevator:

The two ends of the traction rope are respectively connected to the car and the counterweight, and are wound on the traction sheave and the guide wheel. The traction motor drives the traction sheave to rotate after speed change by the reducer. The traction force generated by the friction between the traction rope and the traction sheave ,

Realize the lifting movement of the car and the counterweight to achieve the purpose of transportation. The guide shoe fixed on the car can move up and down along the fixed guide rail installed on the wall of the building hoistway to prevent the car from skewing or swinging during operation. The normally-closed block brake is released when the motor is working, so that the elevator will run. When the power is lost, the brake will stop the elevator car from rising and falling, and maintain its static state on the designated landing for people and goods to enter and exit.

The car is a box component that carries passengers or other loads. The counterweight is used to balance the car load and reduce the power of the motor. The compensation device is used to compensate the tension and weight changes in the movement of the traction rope, so that the load of the traction motor is stable, and the car can be accurately stopped. The electrical system realizes the control of elevator movement, and at the same time completes floor selection, leveling, speed measurement, and lighting. Instruct the call system to display the direction of movement of the car and the location of the floor at any time. The safety device ensures the safe operation of the elevator.
