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