The disclosure relates to a system for monitoring wind influences on a working machine, such as a mobile crane or crawler crane, comprising at least one detection unit that is arranged on the working machine and by means of which a current wind speed can be detected, a recording unit that is configured to receive, to store, and to transmit data of the detection unit during and outside the operation of the working machine, a controller of the working machine that is configured to determine a current working machine state, an external processing unit that is configured to directly or indirectly receive and process data from the detection unit relating to an current wind speed and data from the controller, and an output device that is configured to receive data from the external processing unit.

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

A method of recognizing obstacles on operation of a vibratory pile driver of a work machine includes monitoring an acceleration signal of the vibratory pile driver during operation of the vibratory pile operator and analyzing the acceleration signal to determine the presence of an obstacle. The acceleration signal may be monitored over a time period which is determined based on an excitation frequency of the vibratory pile driver. The analysis may include comparing negative and positive half-waves of the acceleration signal. Responsive to the analysis indicating an obstacle, a system operator may be alerted, and/or operation of the vibratory pile driver may be adjusted via controller intervention.

The present invention relates to a method of power management during pile foundation having a base machine for excavating a borehole and an attachment installed at the base machine for a simultaneous introduction of a casing into the ground, wherein the energy supply for the attachment is at least partially provided by the base machine and a control of the base machine dynamically regulates the energy flow from the base machine to the attachment.

A method of compacting soil via a base machine, the base machine having ram material provided at at least one cable and having a regulation/control apparatus, includes raising the ram material from the land area to be compacted, with a zero point being stored at which no slackline is present. The method further includes raising the ram material to a lift height, carrying out a compaction procedure by dropping the ram material from a drop height onto the land area to be compacted, again raising the ram material from the land area to be compacted, with a further zero point being stored at which no slackline is present, determining and storing a compaction progress, and repeating the previous steps until the compaction progresses of each of a predefined number of consecutive compaction procedures are smaller than or equal to a predefined minimum progress.
