An implement attachment adapter, including a centrally located top clevis; two spaced apart lower devises located below the centrally located top clevis and on opposing sides of a line extending vertically through the top clevis. The two spaced apart lower devises being are recessed into or behind a first face of a flat plate. The flat plate further includes side tabs located proximate each horizontal peripheral edge thereof extending outwardly away from the first face of the plate. A bottom tab extends outwardly downwardly away from the first face at an obtuse angle relative to the plate. A top bar extends across proximate a top portion of the plate and outwardly away from the first face of the plate and is oriented at an acute angle to the plate. The plate further presents engagement apertures and a second face opposing the first face to which the implement may be coupled.

A hydraulic excavator tool adapted to be secured to the distal working end of an excavator boom including a main tool assembly with a tool framework, a spaced apart pair of connection flanges fast with the tool framework, and, a structural tubular casing integral with the tool framework extending across and through the tool framework and through the flanges, plus a rotary hydraulic actuator within the tubular casing extending between the connection flanges and providing a rotational drive motion to a drive axle extending between the connection flanges adapted to provide a controlled rotary drive motion of the axle adjacent the connection flanges, and a working tool framework fast to the axle adjacent each of the connection flanges for relative controlled rotation of the working tool framework about the drive axle between the tool framework and a working position.

This invention related to a coupler for securing an attachment to an earth working machine. The coupler comprises a coupler body that presents a receptacle having a capture region. A pin of an attachment can move into and out of the capture region. A retainer can capture the pin in the capture region but the retainer can be moved by a hydraulically driven driver to a position to allow release the pin from the capture region. A trigger that the pin will strike when the pin moves into or out of the capture region, decouples the driver from the retainer and the retainer is then allowed to be biased back to its retaining position by a spring.

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.

Improvements to work attachment assemblies and in particular work attachment assemblies for use with work machines such as excavators.

A quick-change coupler device for coupling and uncoupling implement attachments to and from construction site equipment includes a carrier assembly, first receiving members disposed on one side of the carrier assembly for receiving a first coupling member, second receiving members disposed on the other side of the carrier assembly for receiving a second coupling member, a locking unit dedicated to the second receiving members and capable of moving between a release position and a locking position, and a catch unit disposed on the carrier assembly for catching the implement attachment. To simplify coupling and to ensure an increased safety level, the catch unit comprises at least one catch hook swivel-mounted on the carrier assembly and a control unit controls swivel of the catch hook between a folded-in and a folded-out position. The control unit is actuated by the first coupling member and is actuated independently of the locking unit.

The single cylinder hydraulic coupler includes a hydraulic cylinder system, a first pivot linkage system, a second pivot linkage system, a first spring system, a second spring system, a first locking pin system, and a second locking pin system. The single cylinder hydraulic coupler couples an attachment to a machine with increased efficiency and reliability over conventional methods.

There is provided an attachment coupling link, including: a cover having a pair of boom link coupling shafts coupled thereto in parallel with each other; a fixing hook fixedly coupled to a lower end of one side of the cover to have a first connection bar of an attachment removably coupled thereto; a pivoting hook coupled to a lower end of the other side of the cover to be pivotable about a pivoting hook pivoting shaft, a second connection bar of the attachment being removably coupled to the pivoting hook; a connection bar release prevention lever pivotably coupled to an upper end of the fixing hook; and an operating cylinder disposed between the fixing hook and the pivoting hook, the operating cylinder allowing the second connection bar to be mounted in or dismounted from the pivoting hook by adjusting a pivoting angle of the pivoting hook.

An attachment coupling device for heavy industrial equipment, includes a coupler body coupled to operation links of the heavy industrial equipment, a fixed hook fixedly mounted to the coupler body, a movable hook rotatably coupled to the coupler body, an actuator connected to the movable hook and rotatably connected to the coupler, and a pin locking unit rotatable through operation of the actuator, to lock a first pin of the attachment coupled to the fixed hook and the movable hook, to which a second pin of the attachment is coupled. The pin locking unit includes a pivot body rotatably coupled to the coupler body and connected to the actuator, a hook support for locking the movable hook, a pin support for locking the first pin, and a locking elastic member for preventing the pivot body from excessively pivoting in a release direction thereof.

A computer-implemented method for a working machine. A processor device of a computer system is configured to receive movement data from sensors that measure movements of the working machine and movements of an attachment tools. Based on the received movement data, the processor device determines movement patterns for the working machine and the attachment tool. The movement patterns are compared and, upon determination by the processor device that the movement pattern of the attachment tool matches the movement pattern of the working machine, the processor device determines that the attachment tool is attached to an arm or a boom of the working machine.
