The present invention relates to a method for controlling a vibrating pile driver when driving a pile element () into a ground (), wherein the vibrating pile driver includes a vibration unit () connected with the same and is attached to a carrier machine (), the method comprising the following steps: detecting at least one first status parameter of the carrier machine () and detecting at least one second status parameter of the vibration unit (). The method is characterized in that with reference to the at least one first status parameter and the at least one second status parameter a statistical ground model is generated, and individual operating parameters of the carrier machine () and the vibration unit () are adapted to the statistical ground model, in order to optimize the energy consumption and/or an advance rate when driving in the pile element ().

Method for controlling a vibrating pile driver

The present invention relates to an attachment for drilling and/or foundation work, in particular a casing oscillator or casing rotator, comprising a receiving apparatus for clamping at least one pipe and a drive for generating a rotational movement of the clamped pipe, wherein the attachment comprises at least one integral control unit for an independent carrying out of control functions of the attachment.

Attachment for drilling and/or foundation work

A method for controlling the fill volume of a grapple, such as a bulk-material crane grapple which includes at least one hoist-and-closure unit, may include adjusting the fill volume of the grapple is during the grapple closure process by adjusting/controlling the grapple hoist height. The grapple hoist speed and/or grapple hoist height may be the controlling parameter for the adjustment of the fill volume of the grapple.
