Abstract: The invention relates to a drilling apparatus arrangement with a drilling apparatus which has a crawler running gear, on which a drill mast with a drill drive is supported that is designed for driving a drill rod and supported in an axially movable manner along the drill mast, wherein the drill mast is adjustable via a multi-joint arm into a plurality of drilling positions in space, and with an operator's cab for at least one operating person for controlling the drilling apparatus. According to the invention the operator's cab is designed as a mobile operating unit that is arranged separately from the drilling apparatus on an independent running gear, the mobile operating unit is provided with a drive means that is designed for driving at least one working means, and the mobile operating unit is provided with a support arm and a gripping means as working means that is designed for handling drill rod elements.

Abstract: The invention relates to a vibration generator comprising a working piston and to a construction apparatus having a vibration generator, wherein the vibration generator is operated by a pressure fluid and comprises a control device having a control piston, which is supported in a displaceable manner inside the working piston.

Abstract: The invention relates to a device for charging a drilling device of an earth or rock drilling apparatus with a double rod. The device has a rotatable revolver magazine, which is designed with double receiving spaces for receiving two tube parts that are inserted into one another.

Abstract: A drill frame or drill platform 1 is allocated to a ship caisson 6 in order to allow bore holes 12, 13 to be driven, for example, into the bottom of a lake 11. Since said bore holes 12, 13 must subsequently be filled with explosives, the use of several drill tools 25 of different design is necessary and possible because a rod magazine 20 comprising several different drill tools 25 is allocated to said drill frame 1. It enables simple and rapid replacement because a conventional clamping device 29 and clamping and crushing device 30 can be employed. The individual drill tools 25 are each equipped with adapters 31 of identical design so that they can be seized and actuated safely using the described clamping and drilling (sic) devices 29, 30.

Abstract: The invention relates to a ground working implement and to a method for introducing a working element into the ground, using vibrations. By means of a vibration generator vibrations are generated and transmitted to the working element during its introduction into the ground. According to the invention a gentle vibration generation and transmission are brought about in that the vibration generator has at least one vibrating piston mounted in linearly displaceable manner in a casing spaced from the working element. The vibrating piston is driven in oscillating manner in the casing for generating vibrations. The vibrations are transmitted via the casing to the working element.
