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.

The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement (2) for making a trench (5) in the ground, a consolidation and laying means (3) being arranged behind the blade arrangement (2), for clearing and safeguarding the trench (5) 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.

A detection system used to alert an operator of a work machine of humans or objects dangerously close to the machine or a work tool attached to the machine. The detection system uses one or more cameras to capture images of an area surrounding the machine. The captured images are displayed on an interface electronically connected to a processor. Prior to operation, one or more zones surrounding the work tool or work machine are defined and projected on the images displayed on the interface. The processor analyzes the images captured by the cameras and determines if a characteristic of a predetermined object is within one or more of the identified zones. If the processor determines the characteristic of the predetermined object is within one of the zones, the processor will identify the object on the display and trigger a warning system to alert to the operator to take necessary precautions.

A display device has a display screen that displays a real image captured by an image capture device mounted in a construction machine which includes working equipment, and a combined image obtained by overlapping an object image indicating a virtual viewpoint image of an object around the construction machine viewed from a virtual viewpoint of an outside of the construction machine and a construction machine image indicating a virtual viewpoint image of the construction machine viewed from the virtual viewpoint, wherein the display device displays the combined image simultaneously with the real image in a partial region of the real image displayed in the display screen.

A subsea plough includes a plough share coupled to a chassis, boulder clearance and spoil clearance members, and front and rear support surfaces. In a first configuration, a maximum span of the boulder clearance member in an extended position is greater than a span of the spoil clearance member. The plough may be reconfigurable to include a backfill member. A method of use of the plough is provided in a boulder clearing only mode, and optional modes of simultaneous boulder clearing and trenching, second pass trenching, and backfilling a trench to bury a flexible elongate member in a seabed.

A controller (40) of a hydraulic excavator (1) includes: a first distance calculation section (43f) calculating a first distance D1 that is a distance between a bucket toe and a target surface on a virtual straight line Lv extended vertically from the bucket toe, based on position information on the bucket toe and position information on the target surface (700); and a second distance calculation section (43g) calculating a second distance D2 that is a distance between the target surface and a current landform on the virtual straight line Lv, based on the position information on the bucket toe and the position information on the target surface and position information on the current landform 800. A display device (53a) displays the first distance D1 and the second distance D2.

A subsea trencher for arranging at least partly into the seabed a subsea pipeline, includes at least one cart that separately carries at least one trench tool and is configured to run along the subsea pipeline. trench tool is configured to work the seabed underneath the subsea pipeline. A subsea support frame carries heavy subsea equipment connected to the trench tool for operating the trench too. When the subsea support frame is fixed to the cart, the subsea trencher is configured to load the assembled weight of the cart and subsea support frame onto the subsea pipeline as the subsea trencher runs on the subsea pipeline. When the subsea support frame is separate from the cart, the subsea support frame is configured to be suspended above the seabed or arranged beside the subsea pipeline at a distance from the subsea pipeline as the cart runs along the subsea pipeline.

A the 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 computer-implemented method for dynamic landscape channeling using an autonomous robotic soil dredger. The method derives one or more landscape metrics, wherein the one or more landscape metrics comprise soil metrics, environmental conditions, and vegetation water consumption metrics. The method further generates a digital twin of proposed trench and ridge metrics based on the derived one or more landscape metrics, wherein the proposed trench and ridge metrics comprise a depth of the trench, a distance between one or more trenches, a stream size, a slope of the trench, and a shape of the trench. The method further determines a trench pattern based on the generated digital twin of the proposed trench and ridge metrics and collaborates with the autonomous robotic soil dredger to generate the trench pattern.

A hydraulic excavator acquires operation content frequency data in a designated period based on output values output from a plurality of sensors sensing parameters that serve as indicators of operation contents performed via an operation device. A storage section stores a plurality of guide screens each corresponding to one of a plurality of work patterns of the hydraulic excavator. A work identifying section searches actual result data in the storage section for actual result data that matches or is similar to the operation content frequency data acquired by the data acquiring section in terms of operation contents and frequency thereof, and that identifies a current work pattern based on a work pattern allocated to actual result data related to a result of the search. A display device displays a guide screen corresponding to the work pattern identified by the work identifying section among the plurality of guide screens.
