Abstract: A coupling for providing a connection and establishing fluid communication between fluid lines is provided. The coupling includes a housing defining an internal cavity with an open end, and a male component engageable within the internal cavity through the open end. The male component has a shank portion adapted to engage a fluid line. The coupling also has a nut securable to the housing and adapted to surround a portion of the shank portion and radially and axially restrain the shank portion within the internal cavity. The nut is further adapted to allow the male component to rotate with respect to the housing and the nut about a longitudinal axis of the shank portion. The coupling further includes a sealing ring provided about the shank portion which is adapted to at least partially block axial and radial movement of the male component relative to the nut and the housing.

Abstract: A support assembly for hydraulic lines is disclosed. The support assembly includes a frame designed to retain at least one ring within its opening. Each ring is configured to be secured about a single hydraulic hose, thus simultaneously securing it within the frame. Each ring can rotate with respect to the frame about their longitudinal axis, reducing the stress exerted directly on the hydraulic line. The support assembly further includes a second frame in which the frame is attached. The frame can rotate about an axis that is perpendicular to the rotation of the rings to further lessen the stress on the hydraulic lines. The support assembly is attached to a hydraulically operated machine by a base plate or bracket onto which the second frame is fixedly attached.

Abstract: A self-lubricating swivelling coupling for interconnecting lines, includes a housing with internal surfaces defining a cavity. It also includes a male component, including a shank and a flange provided on the shank, insertable within the cavity to enable the flange to be abuttable on the internal surfaces. The coupling also includes a nut securable within the cavity, to abut axially via an internal axial projection on the flange, and to surround the shank, allowing the male component to rotate. The fluid leaks between the components to lubricate the coupling. Lines are connectable to ports to be swivellably interconnected without needle- or ball-bearings. There is high surface contact and support between the flange, shank and nut, to withstand and distribute forces. Hydraulic fluid is preferred. A seal-unit between the male component and the nut, and a slide-ring between the flange and the nut, are also preferred.

Abstract: A swivelling coupling assembly for providing a swivellable interconnection between fluid-containing lines. The assembly includes a housing and a retention member for retaining the housing while cooperating with it to allow the housing to spherically swivel therein. The housing has a bore for allowing hydraulic fluid to flow between the interconnected lines. The assembly also includes at least one male component removably mountable within the bore of the housing to be swivellable therein and to prevent external leakage of the fluid. The male component is connected to one line and has a canalization allowing the fluid to flow between the pair of lines through the assembly. Multifunctional swivel functionality is achieved to reduce the torsion on interconnected lines, such as during operation with dynamic machinery.

Abstract: An adjustable spiral sleeve for wrapping around lines for protecting and regrouping the lines includes a support strip for extending longitudinally alongside the lines, the support strip including a plurality of connectors longitudinally distributed and spaced-apart therealong. The sleeve also includes a wrapping strip spirally wrappable around the lines and connectable to the connectors of the support strip at adjustable positions along the wrapping strip to form a plurality of adjustably-sized loop portions of the wrapping strip around the lines. The sleeve enables adjustable fitting around lines. The adjustable spiral sleeve is especially useful in protecting hydraulic lines in dynamic machinery such as that used in the forestry industry and/or mining industry.
