A hydraulic tool for use with a clamp connector where a first clamping element and a second clamping element of the clamp connector are pivotable towards each other into a closed position by exerting a pulling force on an operating shaft and a pushing force on a spacer sleeve, and where said first and second clamping elements are lockable in said closed position by tightening a locking nut against a shoulder on the spacer sleeve. The tool includes a pulling element; a hydraulic power unit for moving the pulling element in relation to the spacer sleeve and thereby allow the hydraulic tool to exert a pulling force on the operating shaft and a pushing force on the spacer sleeve; a rotatable actuating member with a socket engageable with the locking nut; and a drive motor for rotating the actuating member to allow the actuating member to rotate the locking nut.

An agricultural implement including a frame with a main frame section and at least one wing frame section such that the agricultural implement is configured for transitioning in between a work position and a transport position, at least one conveyance line, and at least one coupling device. The at least one coupling device includes a first coupling member attached to the first line portion and a second coupling member movably connected to the first coupling member and attached to the second line portion such that the at least one coupling device couples the first line portion and the second line portion of the at least one conveyance line in the work position and uncouples the first line portion and the second line portion of the at least one conveyance line in the transport position.

A coupler for coupling an attachment to an excavator or other machine comprises a powered actuator for actuating a locking member into and out of said locking state, a first power coupling unit, and a second actuator for moving the power coupling unit into and out of an engaging position in which it is engagable with a corresponding second power coupling unit of the attachment. The coupler is configured to cause the first power coupling unit to move into the engaging position after said latching member adopts the locking state and, when decoupling the attachment from the coupler, to cause said latching member to remain in its locking state until after the first power coupling unit is moved out of its engaging position.

A fitting for coupling to a pipe includes a sleeve for receiving the pipe and a sealing member to provide a seal between the sleeve and the pipe. A pressure ring acts on a pressure member through adjoining slanting contacting surfaces of the pressure ring and pressure member, respectively. The sealing member is configured to be displaced from the slanting contact surfaces to preserve the life of the seal.

A machine for the working of sheet materials is described, which includes a support frame, a supporting head, a working means with rotary tools and a waterjet cutting tool. The machine is provided with fast-couplers that include first and second male fast-couplers respectively disposed on the working means with rotary tools and on the waterjet cutting tool, and first and second female fast-couplers disposed in the supporting head. The female fast-couplers are configured in such a way to permit the alternative coupling with the first male fast-coupler or with the second male fast-coupler.

A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. Disclosed embodiments gain advantage from the internal work pressure to provide improved seal performance. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. When the adapter enters the housing assembly: (A) locking elements on the housing assembly constrict about the adapter; and (B) at least a first seal section on the adapter sealingly contacts a first seal bore on the housing assembly. Progressive engagement of a locking ring upon the locking elements urges the locking elements to tighten against the adapter. Internal pressure encourages adapter displacement, which then further tightens the adapter against the locking elements as now restrained by the locking ring. Internal pressure further encourages the first seal section on the adapter to expand radially to tighten the contact with the first seal bore in the housing assembly.
