The car of the lift moves in a vertical shaft. Stopping is only possible at defined stops, which are permanently programmed. There are models where the drive is attached to the car itself or to the counterweights. These are more space-saving and can be better installed in existing buildings or in private housekeeping. In order for the car to stop at ground level at the lowest landing, a pit must be excavated for the shaft. If the lift is to touch down on the ground, a ramp should be installed for barrier-free access.
Each lift is equipped with a control panel and an emergency call system. In addition to a minimum size, elevators for the disabled must also meet special technical equipment requirements. Encryption is used to prevent use by unauthorized persons. A special key switch permits travel only with the appropriate key. In addition, the car should be equipped with a dead man's control system. In this case, the system only moves as long as the control or button is pressed.
