Abstract

A setup for storing and transporting long workpieces includes at least two yokes in which the workpieces are received on a bottom part and between two vertical side parts joined thereto. The yokes are stackable on one another and the side parts have an engagement device for engagement of load receivers of a lifting system. The setup is provided such that the engagement device of the load receivers (69, 70, 75-78, 83, 84, 91, 92, 105, 106, 120, 121, 128, 129) are formed by at least one protrusion (58-61, 87, 88, 95, 96, 101) on the outside of each side part (32, 33). The lifting system (6), associated with each side part (32, 33), has two load receivers (69, 70, 75-78, 83, 84, 91, 92, 105, 106, 120, 121, 128, 129) and at least one load arm (26, 27, 73, 74, 82, 89, 90, 102, 118, 119, 126, 127) extending substantially vertically downward and supporting the load receivers (69, 70, 75-78, 83, 84, 91, 92, 105, 106, 120, 121, 128, 129). The load receivers (69, 70, 75-78, 83, 84, 91, 92, 105, 106, 120, 121, 128, 129) are adjustable between a position horizontally beside the protrusions (58-61, 87, 88, 95, 96, 101) and a position below the protrusions (58-61, 87, 88, 95, 96, 101).
