A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a link unit attached to the upper turning body, and a processing circuitry configured to align an end of the link unit with an end attachment to be attached.

The subject matter of this specification can be embodied in, among other things, a multi-axis rotary actuator that includes a first rotary piston actuator configured to controllably actuate a first pivotal joint between a first linkage to a second linkage about a first axis, and a second rotary piston actuator configured to controllably actuate a second pivotal joint connecting the second linkage to a third linkage about a second axis.

A system is suitable for connecting multiple implements to a three-point hitch of mobile machinery for controllable side-shifting movement of the connected implements. The system comprises first, second and third apparatuses, each apparatus comprising a first framework, a slidable second framework laterally slideable relative to the first framework, at least one connector supported by the slidable second framework for connecting the slidable second framework to one of the implements, and at least one driver connected to the first framework and the slidable second framework for driving the slidable second framework laterally back and forth relative to the first framework. The second apparatus is attached to one side of the first apparatus and the third apparatus is attached to the other side of the first apparatus.

A modular dangle support for an articulating boom includes at least two modules a spar module and a dangle head module. The spar module has a first end and a second end. The first end has a coupling. The second end has an articulated boom mounting, whereby the spar module is attached to an articulated boom. The dangle head module is detachably secured by the coupling to the first end of the spar module. It is anticipated that there will be more than one dangle head module, with only one dangle head module being used at any one time. Dangle head modules are changed to accommodate different dangle head configurations and different load capacities.

A skid-steer implement allows for the rotation of a tool attachment relative to the body of the skid-steer by coupling an attaching element and a rotation attachment device with a shaft and force generating devices. The slim construction of the device allows for bucket rotation while limiting the tipping load change caused by the extension of the implement.

A pivoting connection between a bucket and a padlock of a rope shovel, a pin assembly, and a rope shovel are disclosed. A pivoting connection includes a pin having a pin axis and extending through a bucket lug of the bucket and a pair of padlock lugs of the padlock; a flag having a pin end and a mounting end; a locking coupling coaxial with the pin axis and located in the pin end of the flag, wherein the locking coupling selectively couples the flag to the pin; and a slotted flag mount attached to the bucket including a vertical slot and a horizontal slot parallel to the pin axis; wherein the mounting end of the flag is received by the slotted flag mount such that the pin is constrained from rotating with respect to the bucket and from translating along the pin axis.

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 joint element provided with a swing dampener element and comprising a first joint part, a second joint part, and a swing dampener brake. The second joint part comprises a second end part which is detachably fixed to a first end part of the second joint part by a joint part coupling which is adapted to allow the second end part to be moved in an axial direction to a detached position in relation to the first end part, the detached position allowing replacement of active components of the swing dampener brake while the first end part remains bearing-mounted to the first joint part, the active components of the swing dampener brake comprising at least one first brake disc member and at least one second brake disc member.

The invention relates to a device (10) for conducting hydraulic fluid from a first connection (42, 44) to a second connection (38, 40) via at least one conduit (56, 58), having a housing comprising a first housing part (10a) having the first connection (42, 44) and a second housing part (10b) having the second connection (38, 40), which parts can be rotated relative to each other about an axis of rotation (10c) and have a hydraulic rotating union for transferring the hydraulic oil, and securing means (50, 52) are provided for securing the device (10) laterally to a torque motor (20), which comprises a first part (20a) and a second part (20b) that can be pivoted relative to the first part (20a), said first housing part (10a) having a central housing (66), said second housing part (10b) having a central body (68), and said central housing (66) and said central body (68) mutually engaging and being rotatably mounted relative to each other. The invention is characterised in that at least one of the conduit arms (64, 70, 72) extends substantially radially away from the central housing (66) and from the central body (68), in relation to the axis of rotation (10c), and in that the second housing part (10b) comprises securing means (52) which are associated with the second part (20b) of the torque motor (20).
