Abstract:
An implement for use with an excavator includes a lightweight housing, a first coupling feature, a ground penetrating radar antenna, a controller, a wireless communication circuit and a rotation unit. The lightweight housing has an upper surface, a lower surface and a cavity. The first coupling feature is located on the upper surface and cooperates with a second coupling feature on an excavator arm. The ground penetrating radar antenna is mounted near the lower surface. The controller is mounted within the cavity and provides outgoing signals to the radar antenna, receives incoming signals from the radar antenna and interprets the incoming signals so as to provide implement output information. The wireless communication circuit is mounted within the cavity and transmits the implement output information. The rotation unit is mounted within the cavity and rotates the housing vis-a-vis the excavator arm.
Abstract:
The invention relates to a solution for presenting information describing a running operating condition of a demolition robot (3:1), provided with a microprocessor (24), a memory (26), wherein current data are obtained by sensors (21 ) as well as recorded and compiled into a data file (db1:1-db1:n) for each recording instance. According to the invention, a data file with specific reference data (27) is recorded in the demolition robot's memory, current sensor data (21) that deviate from recorded specific reference data and thereby can affect the running operating condition of the demolition robot are identified in a first controller (30), identification of deviating sensor data (A) in the first controller (30) takes place during a determined time period (T), information about identified deviating sensor data (A) is stored in the memory (26), a key indicator (41, 42) that describes a current operational parameter for the demolition robot during the determined time period, during which deviating sensor data (A) are identified, is ascertained in a second controller (32), and the key indicator (41, 42) as well as information about identified deviating sensor data (A, 43) to the determined time period (T) are presented in a user interface (28).

Abstract:
A seabed plow capable of over-the-stern release and retrieval is usable in any of boulder clearing, trench cutting and backfill modes. In its boulder clearing mode, the plow uses its skid in torquing configuration followed by moldboards to push boulders out of the path to be trenched. In the trench cutting mode, the plow uses the skid in the same configuration with its share and moldboards for initial trench depth and the same share and moldboards with moldboard extensions for increasing trench depth in subsequent passes. In the backfill mode, the plow uses its skid in trench-straddling configuration following a blade with a passage designed to discharge fragmented spoil directly onto the pipe being covered. Thus, a single plow can be reconfigured for all modes for release and retrieval to and from a relatively small vessel without use of heavy lifting equipment.
Abstract:
A system and process for controlling propulsion and steering of a track trencher excavation machine powered by an engine includes a multiple mode propulsion and steering control system that performs a plurality of functions depending on a selection of one of a plurality of operational modes. A controller generates a vehicle propulsion hydrostatic drive signal optionally using a track drive hydraulic pressure or a track drive speed as a variable for modifying the propulsion drive signal. The controller optionally uses a hydraulic attachment drive pressure as a variable for further modifying the propulsion drive signal.
Abstract:
A method of assisting an operator of an excavating machine is disclosed. The method includes recommending a hop distance (d) to move the machine based upon the maximum distance the machine can move and still be able to reach the bottom (79) of the excavation that has already been dug by the machine during an excavating operation.
Abstract:
A method and device to navigate excavation towards a target buried in an excavatable material, for example excavation near an underground pipeline by excavation equipment. The device generally comprises indicating material arranged to be buried in the ground in proximity to the target. The indicating material is arranged to be frangible for permitting a portion of the indicating material to be removed from a remainder either by tearing, separation at separated sections or separation at perforated lines of severance. Different visual proximity indicators on the indicating material cause different sections of the indicating material to be visually distinct from one another corresponding to different degrees of proximity to the target. In use, the indicating material is placed in the ground and excavation towards the target results in portions of the material being removed. Proximity is indicated by associating which section a removed portion of the indicating material corresponds with. The proximity indicators may comprise use of varying colour, scaled indicia or other suitable notation.
