摘要： A mast for a carrying system has carriers which can be vertically moved by way of a runner guided on the mast and which are used for holding stage-related implements. The mast includes several tube sections of the same diameter which are aligned with respect to one another, and an interior tube piece by which the tube sections are connected with one another at a boundary. The interior tube piece is a sleeve which is slotted along a surface line, thereby defining a slot, and is penetrated by at least one pressure screw which acts by way of a pressure piece with a convex outer contour upon counterpressure pieces. The counterpressure pieces also have convex outer contours and are provided at edges of the slot.
