摘要： The invention relates to the field of excavation systems, and more particularly to excavation systems including tools for excavation by electric pulses. An excavation system of the invention comprises a support frame (34), a hydraulic circuit with a pump, and first and second excavation tools. One of said first and second excavation tools is a mechanical excavation tool (1′) having a hydraulic actuator and a mounting interface with at least one mechanical fastener member and at least one hydraulic coupling in fluid flow communication with said hydraulic actuator, while the other one of said first and second excavation tools is a tool (1) for excavation by electric pulses, comprising an electricity generator (3) with a rotary shaft for generating electricity from rotation of the rotary shaft, a hydraulic motor coupled to said rotary shaft to drive rotation of the rotary shaft, and an electronic power module (4) electrically connected to the electricity generator (3) in order to be powered by the electricity generator (3) so as to generate electric pulses of instantaneous power that is higher than an instantaneous power of the electricity generator (3), a plurality of electrodes (5a, 5p) including at least one electrode (5a) connected to said electronic power module (4), the electrodes being arranged on said front face, and a mounting interface (14) with at least one mechanical fastener member (22), and at least one hydraulic coupling (20) in fluid flow communication with said hydraulic motor (2). Each of the mounting interfaces of the first and second excavation tools is suitable for releasably mounting the corresponding excavation tool in alternation under the support frame (34) of the excavation system, with the corresponding hydraulic coupling in fluid flow communication with said hydraulic circuit of the excavation assembly.

摘要： The invention relates to an automotive construction machine with a transport device extending in the working direction beyond the machine frame, in particular a road milling machine or surface miner. Moreover, the invention relates to a method for displaying an image of the surroundings of an automotive construction machine. The construction machine according to the invention has an image display device for displaying a bird's eye view image of the surroundings of the construction machine, which image display device has a camera system with a plurality of cameras for recording individual overlapping image regions of the construction machine surroundings from different image recording positions, and an image processing system. The image processing system is configured in such a way that image details of the individual image regions are joined together to form a total image from a bird's eye view. The camera system has at least one camera which is arranged on the transport device in such a way that the viewing direction of the camera is directed in the direction of the machine frame, and at least one further camera which is arranged on the machine frame in such a way that the viewing direction of the camera is directed away from the machine frame. Using the cameras directed into and away from the machine frame, the machine operator obtains a complete surround view, which includes the region covered by the transport device in the working direction in front of the construction machine.
