摘要： A bi-directional sled includes a support structure and a shroud assembly. The shroud assembly is supported to the support structure for pivotal movement about an axis extending through the support structure between a first orientation and a second orientation. The shroud assembly has a shroud with a first edge and a second edge opposite the first edge. With the support structure moving the shroud assembly in the first direction relative to material to be dredged friction between the shroud assembly and material to be dredged pivots the shroud and the first edge into a first orientation to contact material to be dredged. With the support structure moving the shroud assembly in the second direction relative to material to be dredged the shroud and second edge are pivoted into a second orientation to contact material to be dredged.

摘要： An earth moving implement for forming a ditch when towed across ground includes a frame, a tow arm connecting the frame to a towing vehicle, wheels supporting the frame for rolling movement along the ground, and a blade assembly comprising a plurality of earth moving blades. The blades include two main blades arranged to be configured to extend rearwardly in opposing lateral directions from a blade apex of the blade assembly such that the earth moving blades diverge rearwardly from the blade apex, and two outer blades supported on the main blades respectively. The orientation of the outer blades relative to the main blades and of the main blades relative to the frame can all be adjusted while the bottom cutting edges remain level with one another to readily vary cutting width and the lateral direction of earth movement by the blade assembly as desired.

摘要： Trench digging and carrying with the same bucket attachment present on one track vehicle, the created dual functionality saves both time and expense by doing on-site what would normally be required to be done with two separate vehicles and additional manpower. The bucket attachment is especially advantageous when used in areas with limited space. Another advantage is that the modification can be adapted to bucket vehicles of various sizes.

摘要： A process and tool for installing and removing various kinds of wear parts used with earth working equipment. The process and tool allows the operator to remove and install the wear parts at a safe distance so that the operator is physically remote from the potential risks of the removal and installation process. The tool may be manually operated via an operator or the tool may be a semi-automated or fully automated.

摘要： A system and method for installing a membrane-lined wall for levee reinforcement or leak prevention. The installation system may comprise a sled positioned above the trench having a length, and may comprise a frame and support members, and a weight suspension system mounted on the frame to lower an elongated weight into the trench. The liner installation sled may also include a liner roller rotatably mounted on the frame, the liner roller adapted to hold a roll of a liner above the surface on a first side of the trench when the liner installation sled is in an installation position relative to the trench, wherein a longitudinal axis of the roll of liner can be aligned with the length of the trench. The elongated weight is usable to force the liner into the trench.

摘要： An apparatus for forming a trench in a sea floor and/or displacing material on the sea floor is disclosed. The apparatus comprises a body and front skids mounted to the body for engaging the sea floor and supporting the body. The front skids are adjustable between a first mode, in which the front skids engage the sea floor, and a second mode, in which the front skids engage the sea floor adjacent the trench and at the trench walls.

摘要： A handheld trenching apparatus and method of forming a trench in ground using the apparatus. The apparatus has a frame, a cutting head, and a drive. The cutting head has a ground penetrating portion with a plurality of cutting members that are caused to be moved in a controlled path by the drive. The frame has an elongate frame part with the cutting head at one frame part end. The frame further has at least one graspable region spaced lengthwise of the elongate frame part from the first elongate frame part end. The ground penetrating portion is directed into the ground and while engaging the at least one graspable region the ground penetrating portion is moved in a trench forming direction as the drive is operated to thereby form a trench.
