An implement includes a mechanical coupling component configured to removably couple the implement to a support machine, a hydraulic fluid supply line configured to receive a supply flow of hydraulic fluid under pressure from a hydraulic system associated with the support machine, and a hydraulically-powered component configured to be actuated using the hydraulic fluid. The implement also includes a hydraulic fluid recovery system comprising a hydraulic fluid return line configured to fluidically couple to the hydraulic system associated with the support machine and provide a return flow of hydraulic fluid to the hydraulic system. A hydraulic fluid reservoir is configured to, when the hydraulic fluid return line is decoupled from the hydraulic system associated with the support machine, receive a portion of the hydraulic fluid from the hydraulic fluid return line when a fluid pressure in the hydraulic fluid return line increases to a pressure threshold.

An outrigger mount assembly includes an arm tube configured to receive and hold an outrigger pole. The arm tube is rotationally displaceable in a lifting direction and in a lateral direction. A hydraulic lifting cylinder with a lifting piston is operationally connected to the arm tube for rotating the arm tube in the lifting direction. A rotation tube is operationally connected to the arm tube. A pinion is affixed to the rotation tube opposite the arm tube. A pair of opposing hydraulically driven rack gears drive the pinion and rotate the arm tube via the rotation tube. An electronic controller with a user interface controls the rack gears and the hydraulic lifting piston.

A simplified and improved pistonless cylinder based on an Aramid fiber reinforced elastomer tubular which is highly stiff in radial direction against radial expansion and elastic in axial extension, so as to form a completely sealed and extendable pressure chamber and to be able to perform as well as, or better than, most of the conventional hydraulic cylinders in terms of load bearing capacities, maximum stroke distances and service durability. This simplified cylinder employs no piston, piston rod, sealing seals or oil based hydraulic fluid, and utilizes non-metal materials to construct the majority of the parts for its extendable pressure chamber; therefore, this new cylinder can achieve significant weight and fabrication cost reduction. In addition, this new pistonless cylinder uses ordinary liquids, e.g., fresh water or seawater, as its hydraulic fluid, and can work directly as a hydraulic or pneumatic cylinder interchangeably without a need for much, if any, modification.

A linear actuator comprising a housing, a top plate securable to the housing at a first end, and a bonnet securable to the housing at a second end. The housing, top plate and bonnet form a sealed cavity, a piston is biased away from the bonnet and a stem is secured to the piston, wherein the stem is axially actuated by motion of the piston and the stem passes through the bonnet to be securable to an actuated component. Further, the actuator can be disassembled and serviced while still attached to actuated equipment.

An actuator includes an actuator piston movable along an axis, a first stop member rotatable about the axis and configured to limit the movement of the actuator piston in a first direction along the axis, a second stop member movable along the axis and configured to limit the movement of the actuator piston in a second direction along the axis, wherein the first direction is opposite to the second direction. A first screw connection is present between the first stop member and the second stop member such that rotation of the first stop member about the axis causes movement of the second stop member along the axis to vary the amount by which the actuator piston can move along the axis in use.

A hydraulic system for a working machine includes a first hydraulic apparatus to be activated by the operation fluid, a second hydraulic apparatus being configured to be activated by the operation fluid, a first operation valve to control the operation fluid to be supplied to the first hydraulic apparatus, a second operation valve to control the operation fluid to be supplied to the second hydraulic apparatus, a first fluid tube connecting the first operation valve to the first hydraulic apparatus, a second fluid tube connecting the first operation valve to the second hydraulic apparatus, a third fluid tube connecting the first fluid tube to the second fluid tube, and an outputting fluid tube connected to any one of the first operation valve and the second operation valve and configured to output the operation fluid supplied from any one of the first fluid tube and the second fluid tube.

A drive system includes: a remote drive configured for being driven by an electrical motor; and an actuator spaced apart from and fluidically coupled with the remote drive and configured for being fluidically powered by the remote drive.

An actuator main body (11) is formed by a plurality of artificial muscles (12). Each artificial muscle (12) includes an elastic tube (13) and a braided tube (15) covering an outside of the elastic tube (13). A first outside cylindrical body (21) is attached to one end portion of the actuator main body (11), and a second outside cylindrical body (22) is attached to the other end portion of the actuator main body (11). Bonding portions (23, 24) are respectively provided in the first and second outside cylindrical bodies (21, 22). The bonding portions (23, 24) are used to bond the elastic tube (13) to the braided tube (15), to bond the outside cylindrical body (21) to the artificial muscles (12), and to bond the outside cylindrical body (22) to the artificial muscles (12).

A cylinder includes a cylinder tube, a first closure part, a second closure part, and a piston unit. The cylinder tube has a first tube end and a second tube end. The tube and end closure parts define a cylinder interior. The piston unit defines at least one working space in the cylinder interior. The first closure part is connected to the tube by a first peripheral laser ring weld and the second closure part is connected to the tube by a second peripheral laser ring weld. The laser ring welds each define a fluid-tight sealing plane. A peripheral sealing ring is located between each closure part and a tube inner wall at an axial distance from the associated laser ring weld seam. The peripheral sealing ring defines a pressure-separated ring section between the peripheral sealing ring and the associated laser ring weld seam.

A working cylinder has a cylinder tube has closure parts arranged at tube ends. The cylinder tube and the closure parts define a cylinder interior. The cylinder has a coupling section that has one of the closure parts, a cylinder tube end and a hollow adapter body. The closure part has an external thread and the adapter body has an internal thread that define a common threaded section constructed to releasably couple the closure part and the adapter body. The cylinder tube end is connected to the adapter body on a cylinder tube side thereof by a ring weld seam. The weld seam defines a sealing plane sealed with respect to a pressure media. The piston unit defines at least one working chamber inside the cylinder.
