A dredging bucket having a head subassembly including an inner rotatable head and an outer head angularly supported by the inner head between level and tilted orientations. First and second opposing bucket halves supported by the outer head and pivotally actuating between closed and opened positions. A pair of T-links incorporated into spaced apart and coaxial pivot locations defined between the bucket halves, each of the T-links having a central stopping bar which, upon the bucket halves rotating to a maximum degree associated with the opened position, contacting end locations defined in upper edge profiles of the bucket halves in order to prevent further opening rotation.

A multi-use garbage truck has an ability to not only to front load containers of garbage into a hopper in a refuse collection body, but also an ability to swap out the forks, if not arm connection assemblies, or even entire frame arms, to be replaced with one of a plurality of attachments which connect to at least one, if not both frame arms with attachments for various uses such as snow plow, leaf blower, street sweeper, bucket, grapple, etc. Furthermore, an ability to independently operate the left frame arm relative to the right frame arm can now be provided so that the left frame arm can utilize and perform one function and the right frame arm provide another or at least be independently operable from one another.

Embodiments of the disclosure provide a dredging apparatus, including a buoyant platform having an upper surface, a lower surface configured to float on a body of water, and an opening having a horizontal cross-sectional area and extending from the upper surface through the lower surface. A set of supports, mechanically coupled to the platform, is configured to maintain a position of the buoyant platform above a dredge site at a bottom of the body of water. A turbidity curtain, coupled to the platform using a plurality of telescoping members, surrounds at least the horizontal cross-sectional area of the opening. A bubble tube frame, coupled to the turbidity curtain and extending outwardly therefrom to surround the turbidity curtain, includes a plurality of outlets configured to emit bubbles into the body of water around a perimeter of the dredge site.

A grapple for mounting to a boom of a boom crane includes a body member for mounting to the end of a boom of a boom crane including a first wing member and a second wing member and opposing first and second jaw members. Each jaw is hingably coupled to the body member, and hinges with respect to the body member by the action of a hydraulic cylinder. A first end of the hydraulic cylinder is coupled to the jaw member and a second end of the hydraulic cylinder is coupled to a portion of one of the wing members. The first and second wing members extend to position the second end of each hydraulic cylinder rearward of an end of the boom of the boom crane or a coupling between the body member and the boom of the boom crane.

A slope-level-cut bucket for an excavator includes a first bucket half and a second bucket half. The bucket halves are pivotably connected to each other and movable between a closed position and an opened position. Each bucket half has an excavating edge configured to minimize bucket overlap during cutting of a sloped surface. In particular, the excavating edge includes a plurality of steps. The dimensions of the steps are selected to optimize the cutting of a desired slope of the excavating surface.

Fully rotating rotary actuator of a multi-purpose machine in which an axle supports the frame of a felling head by a bearing mount, there being a rotary mechanism driven by a rotary motor between the axle and the frame, and in which the connection of the axle includes rotatable joints, the axle includes conduits for electrical cables and a processing fluid line, and in which an additive fluid line tube is arranged in the conduit in the axle and connected to its lower end is a rotatable connector, which is connected to a second tube fastened in the frame for the application of the additive fluid.

A hydraulic excavator tool adapted to be secured to the distal working end of an excavator boom including a main tool assembly with a tool framework, a spaced apart pair of connection flanges fast with the tool framework, and, a structural tubular casing integral with the tool framework extending across and through the tool framework and through the flanges, plus a rotary hydraulic actuator within the tubular casing extending between the connection flanges and providing a rotational drive motion to a drive axle extending between the connection flanges adapted to provide a controlled rotary drive motion of the axle adjacent the connection flanges, and a working tool framework fast to the axle adjacent each of the connection flanges for relative controlled rotation of the working tool framework about the drive axle between the tool framework and a working position.

A grappling apparatus usable with a vehicle is provided. The grappling apparatus includes a connection assembly, a grappling assembly and a stabilizing assembly. The connection assembly connects the grappling apparatus to the vehicle. The grappling assembly has an upper claw assembly and a lower claw assembly. The upper claw assembly has a first plurality of manipulator arms and a walking gear. The lower claw assembly has a second plurality of manipulator arms and a stabilizer gear. The walking gear is meshable with the stabilizer gear and the first and second plurality of manipulator arms are operably connected to the walking gear and the stabilizer gear so as to be moveable between a closed position and an open position. The stabilizing assembly has a stabilizer bar operably connected to the second plurality of manipulator arms and the vehicle so as to stabilize the at least one stabilizer gear.
