Elevator: A fixed lifting equipment with a car body that serves a specified floor and runs between at least two rows of vertical or rigid guide rails with an inclination angle of less than 15 degrees.

Lifting height of the elevator: the vertical distance from the floor of the end station on the ground floor to the floor of the end station on the top floor.China Best elevator manufacturers

Base station: The landing where the car stops when there is no instruction to put into operation.

Distance between floors: the distance between the sills of two adjacent stops.

Hoistway width: the horizontal distance between the inner surface of the hoistway wall parallel to the width of the car.

Hoistway depth: the distance between the inside of the hoistway wall perpendicular to the width of the hoistway.

Pit depth: there is the vertical distance between the bottom station floor and the hoistway pit floor.

Car width: The horizontal distance between the two inner surfaces of the car wall measured at a height of 1m from the bottom of the car in the direction parallel to the width of the car entrance.

Car depth: The horizontal distance between the two inner surfaces of the car wall measured at a height of 1m from the bottom of the car in the direction perpendicular to the width of the car.

Car height: The vertical distance between the floor and the top of the car measured from the inside of the car (the car top lampshade and the detachable ceiling are within this distance).
