The invention provides a boring machine (10) for making a trench (T) in soil (S), the machine comprising a frame (12) that extends along a longitudinal direction (A), said frame (12) carrying a boring device (20) provided with four rotary boring members driven by four motors about axes of rotation that are stationary relative to one another.

A vehicle-attached, task-associated excavation implement with interchangeable rotational excavation apparatuses is conceptualized in this application. The implement is similar to McGee's Tractor-Mounted Excavation Implement, but is conceptualized in a new way of combing parts or portions of the implement with vehicles currently existing in the prior art, without the need for a tractor equipped with power-take-off. This vehicle-attached implement can be supported by a variety of motorized vehicles, utilizing a variety of apparatus-powering options. An assortment of steering options could be used, and movements of the apparatuses, either with or separate from the implement, provide diverse functionality. Tasks supported by the rotational excavating apparatuses include Foundation footings, trenches, rounded ditches, shallow V-shaped ditches, landscape or garden beds, and shallow graded depressions for sidewalks or simple slabs. Excavating apparatuses have claws or cutting elements attached to surface at angles to propel soil directionally.

The display system for remote control of a working machine includes a plurality of camera units and an image processing device, both provided on or in a working machine, and a display device and a remote control device, both provided in the remote control side. The display device detects movement of the head of an operator and transmits the detected movement of the head of the operator to the remote control device. The remote control device transmits, to the image processing device over wireless communications, the movement of the head of the operator transmitted from the display device. The image processing device adjusts, for transmission to the display device, parts of left-eye and right-eye panoramic images according to the movement of the head of the operator transmitted from the remote control device.

A system for uncovering a trench. The system comprises several subsystems, including a work machine and a frame for providing a seal with the surface to be trenched with a saw blade contained therein. The blade is supported on a hub which is slidably movable relative to the frame by operation of a linear actuator, which may be a hydraulic cylinder or the like. The vertical location of the blade within the frame is continuously adjustable to create a deeper or shallower trench. A monitoring system is provided to monitor the vertical location from an operator station.

The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement for making a trench in the ground, a consolidation and laying means being arranged behind the blade arrangement, for clearing and safe-guarding the trench from collapsing while laying at least one flexible casing or tube, cable or wire into the trench. A blade assembly comprising compartments for cooling fluid and air.

A method of cutting a microtrench in which the buried utility is exposed by opening an access hole in a roadway above the buried utility using a roadway access hole drill that is controlled by a computer system connected to an under-roadway detection unit that detects a buried utility and stops movement of the drill to avoid damaging the buried utility. Also provided is a method of drilling a substantially horizontal hole under a roadway using a horizontal drill that is controlled by a computer system connected to an under-roadway detection unit that detects a buried utility and stops movement or changes direction of the drill to avoid damaging the buried utility.

This description provides an autonomous or semi-autonomous excavation vehicle that is capable of navigating through a dig site and carrying an excavation routine using a system of sensors physically mounted to the excavation vehicle. The sensors collect one or more of spatial, imaging, measurement, and location data representing the status of the excavation vehicle and its surrounding environment. Based on the collected data, the excavation vehicle executes instructions to perform an excavation routine by excavating earth from a hole using an excavation tool positioned at a single location within the site. The excavation vehicle is also able to carry out numerous other tasks, such as checking the volume of excavated earth in an excavation tool, navigating the excavation vehicle over a distance while continuously excavating earth from a below surface depth, and preparing a digital terrain model of the site as part of a process for creating the excavation routine.

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 shovel includes a lower traveling body, an upper rotating body rotatably mounted on the lower traveling body, a cab mounted on the upper rotating body, a left monitor mounted on a left pillar inside the cab, a right monitor mounted on a right pillar inside the cab, a left camera configured to capture an image of an area on a left side of the upper rotating body, a right camera configured to capture an image of an area on a right side of the upper rotating body, and a controller configured to control both the left monitor and the right monitor. The controller is configured to cause the left monitor to continuously display a mirror image generated from the image captured by the left camera, and to cause the right monitor to continuously display a mirror image generated from the image captured by the right camera.

The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement for making a trench in the ground, a consolidation and laying means being arranged behind the blade arrangement, for clearing and safe-guarding the trench from collapsing while laying at least one flexible casing or tube, cable or wire into the trench.
