- The elevator is a kind of vertical
elevator powered by a motor, equipped with a box-shaped pod, used for
multi-storey buildings to take people or carry goods. There is also a stepped
type, the stepper is installed on the track to run continuously, commonly known
as the escalator or moving walk. Fixed lifting equipment serving the specified
floors. The vertical elevator has a car that runs between at least two rows of
vertical or rigid guide track with an inclination angle of less than 15°. The
size and structure of the car are convenient for passengers to enter and exit or
load and unload goods. It is customary to regard elevators as the general term
for vertical transportation vehicles in buildings regardless of their driving
methods. According to the speed, it can be divided into low-speed elevators
(below 1 m/s), fast elevators (1 to 2 m/s) and high-speed elevators (above 2
m/s).
working principle
- 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 the speed of the
reducer. The traction force generated by the friction between the traction rope
and the traction sheave , To achieve the lifting movement of the car and the
counterweight, and achieve the purpose of transportation.
