A lift is coupled to the outer cab or rotunda of a telescoping bridge. The lift has a carriage that can be moved by a cable and a motor upward or downward and which includes a platform that has sensing means for controlling the motor for stopping downward movement of the carriage when it engages the ground. An electrically operated safety catch is provided to prevent the carriage form falling in the event the cable breaks. A safety system is provided which prevents the bridge from moving if the carriage is not in the up position and its door is not closed.
