A tile installation plow connected to a mechanical arm of a vehicle to install a tile below a ground surface, the tile installation plow including a main body to be inserted at least partially within the ground surface, a boot removably disposed on at least a portion of an inner surface of the main body to direct the tile along a portion of the main body under the ground surface, and a tile cart connected to the vehicle to hold the tile thereon.

A work machine includes a mainframe, a boom moveable relative to the mainframe, a work implement coupled to and moveable relative to the boom. The work machine further includes a work-implement operator control configured to transmit a signal indicative of a work-implement movement command, a boom operator control configured to transmit a signal indicative of a boom movement command, and a boom sensor configured to detect a movement of the boom and transmit a signal indicative of the detected movement of the boom. The work implement further includes a controller configured to receive signals from the work-implement operator control, the boom operator control, and the boom sensor. The controller is further configured transmit a signal to cause movement the work implement relative to the boom based on the detected movement of the boom and the work-implement movement command.

The invention relates to a civil engineering device and a civil engineering method for using a civil engineering device. The device has a support device, a ground preparation tool, which prepares the ground at a preparation location, and at least one GPS unit, which is arranged on the support device and is designed to determine the position of the preparation location, wherein the GPS unit is arranged at a distance from the ground preparation location. The civil engineering device is characterised in that a measuring device is provided in addition to the GPS unit, the measuring device being designed to determine the distance between the GPS unit and the preparation tool.

A system for uncovering a desired and pre-planned trench. A trenching machine is equipped with sensors, including visual imaging sensors. The sensors detect the inclination of the ground and movement of the trenching machine, as well as the angle of a trenching boom. Using this information, and a pre-determined preferred trench grade, a processor commands the trenching boom to adjust its angle to maintain the preferred trench grade. Surface irregularities may therefore be accounted for along the length of the trench to maintain a constant grade at the trench bottom.

A method and apparatus for installing a monitoring cable or other utility near an existing pipeline. An electromagnetic signal may be induced on the pipeline, either directly, or by transmitting a signal from a vehicle carrying a sensor array. The sensors disposed on the vehicle communicate with a processor to determine a distance and orientation of the vehicle relative to the pipeline. The signal may be electromagnetic, acoustic, capacitive, or the like. A plow or other digging tool may be on the vehicle or a secondary vehicle. Such a digging tool opens a trench and installs the cable along a path disposed next to the pipeline within an acceptable distance range from the pipeline. The vehicle may be remotely or automatically operated.

A system for planning an earth-moving operation to be performed by a construction machine having a tool for performing the earth-moving operation and a machine control unit for at least partially controlling the earth-moving operation, the system comprising a measuring system configured for capturing 3D measuring data of an uneven terrain in a surrounding of the construction machine, a context camera having a known position relative to the measuring system and/or the 3D measuring data and being configured for capturing context image data of the terrain, a user interface configured for displaying at least one context image to an operator of the construction machine and for receiving user input from the operator, and a computing unit operatively coupled at least with the measuring system and the user interface.

The present disclosure relates generally to systems and methods for sensing wear in machines designed to reduce or break-down material. More particularly, the present disclosure relates to systems and methods for sensing wear of reducing elements used by excavation machines such as surface excavation machines. The present disclosure relates to a wear sensing system including a multi-level wear sensor protection system. The multi-level wear sensor protection system includes a first level of protection, a second level of protection, and a third level of protection.

First to third inertial sensors (16, 17, 18) are respectively mounted on a boom (5A), an arm (5B) and a bucket (5C) to rotate in coordinate axes different from each other at the time of operating the boom (5A). In a case where the boom (5A) is operated in a state where a traveling operation pressure Pa and a revolving operation pressure Pb are equal to or less than respective preset operation pressure threshold values, a controller (20) makes a determination on which movable part of the boom (5A), the arm (5B) and the bucket (5C) each of the inertial sensors (16, 17, 18) is mounted, based upon sensor outputs outputted from the inertial sensors (16, 17, 18). The controller (20) sets a corresponding relation between each of the boom (5A), the arm (5B) and the bucket (5C) and each of the inertial sensors (16, 17, 18) based upon the determination result.

The disclosed systems for laying underground fiber optic cable may include a drive body, at least one rotational motor, a forward auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a first rotational direction, and a rear auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a second, opposite rotational direction. Various other systems, methods, and devices are also disclosed.

A mobile device for the underground laying of a flexible line, a cable, a cable-pulling empty pipe or fluid transport tube. A front vehicle has a rear support frame, a lateral ejection unit, a milling unit with a milling wheel and a drag formwork or cable laying unit following the wheel. The milling unit is connected to the front vehicle for lateral pivoting up to 25, in particular up to 20, is laterally offset towards the outside with respect to the front vehicle, and can be positioned to laterally protrude over the contour of the front vehicle, by a primary articulation or a swivel joint on the lateral ejection unit having a substantially vertical axis of rotation. The drag formwork, cable laying and cable introducing unit follows the milling unit and the cable introducing unit are also laterally pivotable about a second swivel joint.
