Abstract
A system for raising and lowering objects includes a carriage subsystem with a tubular body having an interior central channel an inner diameter greater than the outer diameter of an elongated tubular support structure. A plurality of guides facilitate linear translation of the carriage on the vertical structure without marring. At least one hook on the carriage pivots to engage a slot on the support structure for locking the carriage in a raised position. Objects are attached to a flange on the carriage. A winch and cable control motion of the carriage.
