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.

A system and method for automated control of reclaimers includes a boom, a bucket wheel, and a translation system. This system comprises memorizing operating parameters used during a turning movement of the boom, allowing identification of positions where there was an overflow or an unsatisfactory reclaiming flow. With this memorized information, the flow controller makes changes to the boom turning speed (Vg), increasing it in positions where the reclaiming flow was low and decreasing it in positions where there was overflow.

An earth working apparatus, for laying a pipe or cable underground. The earth working apparatus comprises a plurality of trenching modules. Each trenching module is arranged sequentially in a first plane and comprises a cutter in communication with a conveyor. In a second aspect, each trenching module cuts a layer of earth and conveys said layer of earth to a collection device or to a collection area.

A control method and system for avoiding collisions between components of a machine includes a controller that receives position signals from sensors associated with movable components of the machine. The controller determines the positional coordinate representations of the components within a coordinate system based upon the position signals and the outer dimensions of the respective components. If any of the components are within preset collision slowdown or shutdown zones within the coordinate system, then the speed of those components is restricted or the components are shutdown, respectively, in the direction of collision.

A bucket wheel machine 100 having a base 102 and an operating block 104. The operating block has a bucket wheel 106, a bearing 112,114, and at least one of a ring chute 120, a bucket wheel chute 108, and a bucket wheel drive 116. The operating block 104 is detachably attached to the base of the bucket wheel machine 102. The operating block 104 also has a support frame 130 which is connected to the bearing 112,114.

A high-frequency vibrating transverse drum cutter head, and a drum cutter machine and a tunnel boring machine with such drum cutter head are disclosed. The transverse drum cutter wheel of the high-frequency vibrating transverse drum cutter head is driven by the cutting motor to rotate, the transverse drum cutter wheel is provided with cutting teeth, the transverse drum cutter wheel is mounted on one end of the drum cutter head base, the other end of the drum cutter head base is connected to a U-shaped drum cutter mechanism body, a connecting base is mounted on the U-shaped drum cutter mechanism body and used for mounting the high-frequency vibrating transverse drum cutter head on a drum cutter machine or a tunnel boring machine, a vibration box is mounted on the drum cutter head base, and the vibration box is adapted to output high-frequency vibration force to the transverse drum cutter wheel through the drum cutter head base, so that the transverse drum cutter wheel 16 is able to perform high-speed repetitive vibrating movement while achieving its own rotation. Both rotation motion and high frequency repetitive vibration can be implemented at the same time by the present invention, trough the combination of the transverse drum cutter wheel and the vibration box, making the cutting teeth on the drum cutter wheel apply combined action of impacting and cutting on the contacted materials, so as to break hard rock easily.

An excavator machine that includes components such as: a suspended casing having a top end and a bottom end; at least one cable that extends above the casing, where the cable is under tension and has a bottom end that is fastened to the top end of the casing; and a cutter device that is arranged at the bottom end of the casing. The excavator machine further includes: a carriage that is mounted to slide along the cable; a device for moving the carriage along the cable; and a locator device for determining the three-dimensional position of the carriage.
