  • Patent number: 9567731
    Abstract: A method, system, and non-transitory computer-readable storage medium for calibrating an implement actuation sensor of a machine are disclosed. The method may include calculating a first elevation value of an implement of the machine. The method may include calculating a second elevation value of a ground-engaging device of the machine. The method may include, in response to determining that the machine is spreading, adjusting the second elevation value based on a compaction factor to determine an adjusted second elevation value. The method may further include determining a first elevation difference value based on a difference between the first elevation value and the adjusted second elevation value. The method may further include calibrating the implement actuation sensor based on the determined difference.

  • Patent number: 8079163
    Abstract: A number of front working, trench filling face-compressing, inclinedly disposed sliders are arranged alternately with cutter bits on an endless chain of a trench-forming endless chain cutter on a transporting chassis, and driven with the chain by a drive means so that backward oriented, inclined facet portions of the sliders compress a filling in the trench toward and on a front working face of the wall being formed. An elongate, filling face-compressing shield is adapted to be extended down into the trench and supported with its underground portion on the underground portion of a guide post of the cutter or on the trench bottom for forward and backward oscillation by a drive means to compress the filling face adjacent to the shield. The compacted filling is in these ways being formed by horizontal pressure.

  • Patent number: 8061065
    Abstract: A number of slot filling-compressing members are inserted from a framework into and across a slot-shaped excavation at ahead of a frontal face of a continuous, compacted slot filling being formed along the slot, and moved with a drive means connected to the members for intermittently forcing portions of the members against the filling to compress the filling adjacent to the members longitudinally against the face. The compacted filling is in this way formed by longitudinal pressure. The members can be mounted for forward or reciprocating movement in directions along and across the face.

  • Publication number: 20100257757
    Abstract: The present disclosure provides a machine configured so that its ground speed is at least in part dependent on the measured force that is applied to an attachment attached thereto. The present disclosure also provides an attachment for a machine that is configured to provide feedback to the machine it is configured to be attached to, wherein the feedback is representative of the force applied to the attachment. The present disclosure also provides a method of automatically controlling the ground speed of a machine based on feedback measured in an attachment attached to the machine.

  • Patent number: 6189244
    Abstract: A narrow-trench earth trencher and flexible tube installer, including a relatively large diameter narrow driven sprocket connected by a chain with attached earth cutters to a relatively small drive sprocket. The trencher includes a carriage frame adapted to be connected to a pulling vehicle, with wheels at one end to facilitate horizontal travel. Mounted on the carriage frame are first and second vertically-oriented trencher frame assemblies. The trencher also includes a vertically-oriented tubular member and a crumber for helping place the flexible tubing in the trench.

  • Patent number: 6058631
    Abstract: A trench cleaning apparatus for attachment to a tractor, the trench cleaning apparatus for extricating crumbs from a trench into control of the tractor. The trench cleaning apparatus utilizes a rigid member having a top edge, a bottom edge, a first side edge and a second side edge. When the rigid member is inserted into a trench at an angle to horizontal and propelled, the first edge and the second edge engage the sidewalls of the trench and the bottom edge of the rigid member engages the bottom of the trench. As the rigid member is propelled, crumbs flow from the bottom of the trench to the top of said rigid member such that crumbs are extricated from the trench and the trench is cleaned. A bucket can be utilized in cooperation with the trench cleaning apparatus such that crumbs above ground level can also be removed.

  • Patent number: 5392540
    Abstract: A trenching bridge mounting interface for a trenching machine that is adjustable to alter the effective length of a fixed length bridge so as to accommodate trenching bars of different lengths. The interface includes a prime mover mounting structure that is releasably secured to the prime mover of the trenching machine and a bridge mounting structure attached to the fixed length bridge. The effective length of the bridge is adjusted between a short length and a long length by reversing of the prime mover mounting structure.
