Abstract: A semi-submersible machine moves on rotatable endless belt tracks over diverse surfaces and has two tools on articulated booms for remediation of roadside drainage ditches, retention ponds and other shallow water bodies. One tool is a cutter bar for cutting vegetation at a plurality of angles and positions above or under water, and the other tool is a rotatable pair of opposing clawlike jaws for raking or scouring soil above or under water to restore percolation performance, and to remove loosened vegetative matter without removing soil and water. The vehicle is submersible to a depth of forty inches, and can traverse a slope of thirty degrees while its tilting control platform remains above water and level, thereby maintaining stability of the vehicle.

Abstract: Concrete crushing tongs comprise a frame-shaped first jaw of tongs (1) and a second jaw of tongs (2) which is connected to the first jaw of tongs (1) at a pivot joint (3). The two jaws of tongs (1, 2) each comprise concrete crushing portions (13, 18) with projections (14, 19). The concrete crushing portions (13, 18) of both jaws of tongs (1, 2) each project beyond cutting edges (11, 17) of the two jaws of tongs (1, 2) in a direction towards the corresponding other jaw of tongs (2, 1). Thus, the concrete crushing function of the concrete crushing tongs is separated from the function of cutting the reinforcement.

Thus an implement may be removably positioned in relation to the bucket of a back hoe for gripping an object therebetween for movement by the boom and for changing one implement for another upon the implement receiving and positioning members. An offset member (E) extends upwardly from the base for aiding in retracting the arm and the implement carried thereby.

Abstract: A multipurpose bucket structure can carry long materials, pull down a building into pieces and take away the pieces, disassembly an automobile and take away the parts, work with a large-sized tool, dig the ground, for put an area destroyed by a disaster in order, carry ready-mixed concrete and carry concrete blocks or secondary products of concrete. In the bucket structure, an openable bucket is attached in an openable manner to a body bucket by an actuating cylinder, and the buckets are formed with tooth portions for grasping materials. The bucket structure thus constructed of the body bucket and openable bucket can be swiveled in a plane normal to the opening and closing direction of the openable bucket. The openable bucket is automatically locked in its closed position and in any open angle position. On the other hand, the swivel mechanism is equipped with a locking mechanism for locking it in a swivel position.

Abstract: The invention relates to a bucket crusher to be mounted in place of the bucket of an excavator or a bucket loader. Horizontal crushing shafts (12) provided with crushing tools are superimposed at a small distance from each other and adapted to be rotated in the same rotating direction. A pivoting axle (4) for a pivotably journalled compression and feeding plate (1) is located in the top section of the bucket. The plate (1) can be turned for pressing the material to be crushed against the crushing shafts, whose rotating direction is selected in such a manner that the crushing tools within said bucket travel towards said pivoting axle (4).

Abstract: A mount for attaching a grapple to an excavator arm equipped with a hydraulic drive, a thumb, and a bucket. A rear portion of the mount is adapted to overlie the thumb to which it is attachable by bolts. A forward portion of the mount is provided with apertured ears that attach by pins to interior fingers of the thumb. The mount includes a second pair of apertured ears that extends forwardly from the thumb and to which a grapple is attachable by a drop link. The hydraulic system of the excavator is modified to permit diversion of the hydraulic drive for the thumb to the grapple when the grapple is mounted on the excavator. The grapple mount significantly reduces the time necessary for mounting and dismounting a grapple to an excavator arm because it eliminates the necessity for mounting and dismounting the thumb and the bucket.
