A modular elevation platform system comprises at least two rail segments releasably connectable end to end to form a rail unit adapted to be secured against an upstanding portion of a structure. The modular elevation platform system also comprises a carriage operatively mounted to the rail unit for translational movement of the carriage along the rail unit. A transmission between the carriage and the rail unit converts actuation to the translational motion of the carriage along the rail unit and a frame secured to the carriage and adapted to support a platform. A method for moving the carriage along a vertical portion of a structure is also provided.
