A tool coupler for coupling a tool to an end of a machine link. The tool coupler having a coupler frame, a hook configured to receive a first pin of the tool and configured to attach to the end of the machine link such that the tool coupler, a wedge slidingly received within the coupler frame, and an actuator connected to the wedge to move the wedge away from the hook to bias a second pin of the tool against the coupler frame. The tool coupler mounts the tool to the machine link such that the tool and the tool coupler pivots about the same axis.

An adapter for a quick-change system for changing attachments on a construction machine contains coupling elements arranged at a stipulated spacing from each other between two side walls for connection of the adapter to a quick changer. In order to provide improved protection from damage, the rear ends of the two side walls project rearwardly with respect to a back cover arranged between the side walls.

A structure of a detachable front loader includes: a main frame; a boom; and a subframe unit that supports the boom. The subframe unit includes: a subframe; a guide that is disposed on the subframe and engages with the main frame; a lock bar that includes a pivot shaft disposed on the subframe, and a pivot shaft part; an operation tool that moves the lock bar from the restriction position to the release position against a first biasing force; and a locking tool that is supported by the subframe, moves between a locking position and an unlocking position, is biased in a locking direction, and once the operation tool moves the lock bar to the release position, moves to the locking position by a second biasing force, and engages with a cutout formed in the pivot shaft part.

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.

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 quick-change system for changing attachments on a construction machine with a quick coupler arranged to be pivotable about a pivot axis orthogonal to the axis of rotation by means of a hydraulic slewing drive and rotatable about an axis of rotation on a connection part by means of a hydraulic rotary drive contains mounts and at least one locking element which can be actuated by means of a hydraulic drive to hold an attachment coupled to the quick coupler. The quick-change system includes a hydraulic control device, which contains a first control circuit to drive rotary drive and slewing drive, at least one additional control circuit to supply the attachment coupled to the quick coupler and a shuttle valve arrangement to expose the hydraulic drive to the higher pressures acting in the first or the at least one additional control circuit to activate the at least one locking element.

A quick coupler includes a housing in which a first and a second coupler cartridge are received. The spaced-apart center axes of the first and second coupler cartridges each run parallel to a vertical axis such that the center axes are contained in a common reference plane. The quick coupler further includes a first actuating lever and a second actuating lever for actuating the coupler cartridges. First and a second axes of rotation of the respective first and second actuating levers are oriented perpendicularly to the reference plane, and a first actuating arm and a second actuating arm are arranged to perpendicularly to the reference plane on opposite sides of the housing.

A work machine controller that is coupled to the boom assembly may comprise of a controller with a memory that stores computer-executable instructions and a processor that executes instructions. The instructions include monitoring a first position signal from the first boom position sensor, a second position signal from the second boom position sensor, the load signal, and the orientation signal. The instructions then include calculating a load vector based on the load signal and the orientation signal, generating a disorientation signal based on the load vector and a direction of travel, determining if the disorientation signal is outside a predetermined threshold, and actuating one or more of the actuators and the ground-engaging mechanism to reorient the load when the disorientation signal exceeds the predetermined threshold.

A grappling apparatus usable with a vehicle is provided. The grappling apparatus includes a connection assembly, a grappling assembly and a stabilizing assembly. The connection assembly connects the grappling apparatus to the vehicle. The grappling assembly has an upper claw assembly and a lower claw assembly. The upper claw assembly has a first plurality of manipulator arms and a walking gear. The lower claw assembly has a second plurality of manipulator arms and a stabilizer gear. The walking gear is meshable with the stabilizer gear and the first and second plurality of manipulator arms are operably connected to the walking gear and the stabilizer gear so as to be moveable between a closed position and an open position. The stabilizing assembly has a stabilizer bar operably connected to the second plurality of manipulator arms and the vehicle so as to stabilize the at least one stabilizer gear.

A quick coupler for construction machines. An embodiment of the quick coupler comprises a housing with two opposing longitudinal walls, two opposing transverse walls, a top side, a bottom side, and a block cylinder inside the housing. The quick coupler may also comprise a locking device with a locking bolt and a drive device. The locking bolt protrudes from one of the two transverse walls in a locked position. The quick coupler may also comprise a first coupling element having a coupling end section and a second coupling element having a coupling end section hydraulically connected to one another, wherein the second coupling element is arranged on one of the two longitudinal walls of the housing.
