The invention relates to a hydraulic rotator (11) for rotating a tool with respect to a crane arm, the hydraulic rotator comprising a first attachment piece (12) for connection to a crane arm and a second attachment piece (13) for connection to a tool; and a stator (14) and a rotor (15), the rotor (15) being rotatably arranged inside the stator (14) to rotate around an axial axis (A), wherein the rotor (15) comprises vanes (18) that are biased to extend radially outwards from said rotor (15), and wherein the stator (14) comprises an inner circumferential surface (25) to receive said vanes (18), which inner circumferential surface (25) comprises at least two chambers (19a) arranged to receive each vane of said vanes (18) to a first extent, and at least two shallow portions (19b) arranged to receive each vane of said vanes (18) to a second extent, which is substantially less compared to said first extent, wherein said inner circumferential surface (25) is arranged to receive at least a tip portion of the vanes (18) throughout its whole periphery.

A device for securing logs from harvested timber to a transport vehicle, or logging truck, using log wrappers. The log wrapper securement device can be located in the inspection cavity of a forestry grapple. The forestry grapple is attached to a log loader. The log wrapper securement device includes a base plate sized and shaped to replace the inspection plate covering the inspection cavity. The base plate includes a slot sized and shaped to receive a portion of a chain end link or other chain links of the log wrapper, which can be inserted manually. The loader operator can remotely control the actuator to secure the chain link and release it, once the log wrapper is positioned over the other side of the logging truck. The log wrapper securement device can potentially reduce injuries and save lives.

A pipe laying device (T) connected to the jib (F) of a transport machine and carrying the pipe to be laid (T) to tight-fit it into a laid pipe (To).

This coupling head (1) comprises a vertical axis (YY) swiveling link (11) and a horizontal axis (Z) tilting link (12). It comprises a guide rail (2) with a bearing (21) for positioning and attachment to the end of the laid pipe (To) and aligning the pipe to be laid (T) with the laid pipe (To) and a carrier (3) forming a telescopic tube (30) tight-fitted to the guide rail (2) and operating in relation to it; the carrier (3) carries the pipe to be laid (T) and tight-fitted to the laid pipe (To).

The guide rail (2) is connected to the coupling head (1) through the telescopic tube (30).

An articulable lifting attachment is provided for a mechanical articulated arm. The articulable lifting attachment comprises an attachment body, a clamping head and a drivable articulator coupling interposed between the attachment body and the clamping head. The clamping head is configured to provide two different clamping forces from different directions to ensure that irregular objects can be lifted safely.

A grapple truck with side loader having a generally J-shaped scoop in a lateral recess of the truck bed sidewall. Sometimes loader is longitudinally truncated forming an adjacent debris-bin vertical transport. The power lift system is either a direct lift-pivot with cylinder lifters or a channel-guided lifter with candy-cane shaped channels. Side loader rises from a low, manual loading position to an upper inverted dump position whereat loader displaces debris into truck bed box. Scoop's loader edge is planarly coextensive or inboard truck sidewall, and at or beneath the truck wheel axis line. A chassis mounted, articulated boom, with longitudinally extending arm segments, terminates in a grapple jaw. The articulated boom and grapple jaw has a longitudinally foreshortened stored position in and above the truck bed. In multiple operative positions, the arm extends beyond the truck bed and rear bed wall and laterally over and beyond truck sidewalls.

A system for lifting a sub-conductor bundle having a plurality of spaced-apart sub-conductors comprises a single point lifter base and an accessory mounted onto a free end of a support. The support is electrically insulated and comprises one or two tiers of elongate insulators extending away from the base. The base is for mounting the support onto a distal end of a boom. The accessory has at least one wire cage mounted on a cart, the cart mounted on an arcuate track and adapted for free translation along the inner side of the track between first and second ends of the track. The wire cage is in a first orientation when the cart is positioned at the first end of the track, and in a second orientation when the cart is positioned at the second end of the track, the first and second orientations perpendicular to one another.
