Abstract:
A lift system comprises a rail (1) and a carriage assembly (2) comprising a seat (21) or platform (21) for supporting a person to be conveyed along the rail (1), drive means arranged to engage the rail (1) and controllable to drive the carriage assembly (2) along the rail (1), energy storage means arranged to power the drive means, input means operable by a user to provide an input signal indicative of a desired movement of the carriage assembly (2) along the rail (1), and control means arranged to receive the input signal and control the drive means in response to the input signal. The system includes charging means arranged to charge the energy storage means when the carriage assembly (2) is at a first charging position on the rail (1). The control means is arranged to monitor at least one voltage (VI, V2) characteristic of the energy storage means and/or at least one operational characteristic of the stair lift, and generate an alert signal in response to one or more of those characteristics, or a difference between one or more of those characteristics, fulfilling a defined criterion, criteria, condition, or conditions.
