Abstract: The invention relates to a drill rod magazine for vertical storage of drill rod elements, having a box-like basic frame which has a support area, vertical side walls and at least one horizontal receiving shelf, which is designed to receive and hold the drill rod elements. The basic frame has a laterally open access area, via which the drill rod elements can be inserted into the basic frame. It is provided according to the invention that the side walls are arranged parallel to each other and each have at least one pivot bearing with a horizontally orientated pivot axis, the at least one receiving shelf is mounted pivotably with respect to the side walls, and the basic frame is designed to be collapsible, wherein the basic frame can be unfolded from a folded-up position into an operating position.

Abstract: The mounting wrench (2) is used to engage or disengage a tool head (24) of a modular tool. The mounting wrench (2) incorporates a base body (4), which extends from an upper surface (20) along a centered longitudinal axis (18) to an underside (22). In addition, it has a slotted part (6), extending in the direction of the centered longitudinal axis (18), with a slot (10), into which the tool head (24) can be inserted. The slotted part (6) has two opposing keys (14), extending radially inward, which are each designed to mesh into a keyway (30) of the tool head (24). The keys (14) have a rounded end face (32), oriented radially inward, and are sloped relative to the centered longitudinal axis (18) so that the distance (a) between the keys (14) increases in the direction of the centered longitudinal axis (18).
