An modular lift system for hoisting objects along a track to a predetermined height. The lift system may include a limit switch, a carriage with an automatic emergency braking system, and a peak to engage the track, whereby the carriage rolls along the side rails of the track between the peak mounted to the top of the track and the bottom of the track. The carriage can be adjustable thereby permitting it to be adapted to various types and sizes of tracks. The automatic emergency braking system is adapted to prevent the uncontrolled descent of the carriage in the event of a cable or primary brake failure.
