Abstract
The elevator has a car movable vertically within a shaft between lower and upper end positions and a drive system coupled to a traction system for controlling movement of the car. A limit switch which is open when the car is in a selected distance range from one of the end positions. The limit switch forms part of a power line supplying power to the drive system for controlling movement of the car in a direction towards that end position in an inspection operation. Thus movement of the car is prevented only in that direction when the car is in the selected distance range in an inspection operation.
