Abstract: The invention relates to a drilling rig with a drilling tower, a base structure, on which the drilling tower is arranged, and at least three support units being part of the base structure, each support unit having at least one wheel rotatable around a horizontal wheel axis, wherein at least one of the support units comprises a vertical steering axis, around which the at least one wheel can be turned by a steering drive. The invention further relates to a method for moving such a mobile drilling rig.

Abstract: Connecting arrangement for a hydraulic cylinder having a cylinder housing and an extendable piston rod, at the free end of which a linkage lug for connection to a construction component is arranged, characterized in that the linkage lug is connected to the piston rod via a plug connection.

Abstract: The invention relates to a device and a method for cleaning or lubricating at least a connecting section of a drill rod element, with a housing, a channel-like recess and at least one washing means or lubricating means which is arranged along the channel-like recess. The channel-like recess is designed for horizontal insertion of at least a lower connecting section of the drill rod element when the drill rod element is substantially in vertical alignment. The invention further relates to a drilling rig with the said device for cleaning or lubricating.

Abstract: The invention relates to a drill rod magazine for vertical storage of drill rod elements, having a base frame, on which at least one support means is arranged that has two substantially horizontally directed retaining arms which, by formation of a receiving area, are parallel to and spaced apart from each other, wherein the drill rod elements are retained in a vertical position between the retaining arms. Along at least one retaining arm a clamping rod is supported in a movable manner which is in operative connection with a tensioning means that exerts a tensioning force onto the drill rod elements for retaining the drill rod elements in a clamping manner in the receiving area.

Abstract: The invention relates to a drill rod store having a first storage area and a second storage area, in which a plurality of drill rod elements are in each case stored in horizontal alignment. Between the two storage areas a trough-shaped receiving part for a single drill rod element is provided. The trough-shaped receiving part is designed to deliver a single drill rod element. For this purpose, a joint supply means is provided, through which drill rod elements are supplied both from the first storage area and from the second storage area to the trough-shaped receiving part.

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.
