A method of coupling a tool to a work machine including inserting a front lug of a coupling assembly into a front recess on the tool, inserting a rear lug of the coupling assembly into a rear recess on the tool, moving a retaining member of the coupler assembly to a retaining position relative to the tool to releasably mount the tool to the work machine, while simultaneously preventing movement of a hydraulic coupling manifold on the coupling assembly from moving; and moving the hydraulic coupling manifold to a coupling position with a hydraulic power transmission coupling on the tool to hydraulically couple the tool to the work machine in response to the retaining member reaching the retaining position.

A dipper handle assembly includes a tube coupled to a yoke. The yoke has a collar extending along a collar axis, a transition portion, a first arm and a second arm. The transition portion includes a distal end having first and second lateral sections and first and second transverse sections. The first and second lateral sections and the first and second transverse sections all lie in a virtual transition portion distal end plane, and the virtual transition portion distal end plane intersects the collar axis at an oblique angle.

A yoke of a dipper handle comprises a collar and a crowd pin aperture extending along a crowd pin aperture axis. First and second arms of the yoke include dipper pin lug apertures aligned along a dipper pin aperture axis parallel to the crowd pin aperture axis. The first and second arms of the yoke further include first and second pitch brace lug apertures aligned along a pitch brace aperture axis parallel to the crowd pin aperture axis. A first virtual reference line extends between the crowd pin aperture axis and the dipper pin aperture axis, while a second virtual reference line extends between the crowd pin aperture axis and the pitch brace aperture axis. An included angle α between the first virtual reference line and the second virtual reference line is between approximately 25 to approximately 51 degrees.

A coupling system for coupling a tool to be carried over the earth to a mobile tool carrier. The system includes an attachment base for attaching the coupling system to the mobile tool carrier and a center pivot assembly with a pivot that allows a tool support arm to swing to either side of the tool carrier where it extends to the side to allow the tool to be used to the side while the machine moves forward. The support arm includes a vertical hinge that divides the arm into two parts, allowing the arm to fold so the tool can be either in front of the machine or beside the machine. The tool may be connected to the support arm with a quick-coupler having hooks or with a permanent attachment.

The invention relates to an implement coupling device (1) on a working machine (2), which device comprises a coupling means (11) provided with a first shaft (21); an engagement means (12) provided with a second shaft (22) arranged parallel to the first shaft (21); at least one linkage (13, 14) comprising a first portion (23, 24) connected to the first shaft (21) and second portion (25, 26) connected to the second shaft (22), which first and second portions are connected by a pivot joint (27); and a wedge (28) means arranged to be removably mounted between the first and second portions (23, 24; 25, 26), wherein the coupling means (11) and the engagement means (12) are displaceable relative to each other in a direction at right angles to the first and second shafts (21, 22) to attach or release the implement. At least one portion (23, 24; 25, 26) making up a linkage (13, 14) is detachably fixed to its respective shaft (21, 22) by a locking means (31, 32, 33, 34) in a longitudinal recess (41, 42, 43, 44) at right angles to the shaft (21, 22) and engaging with a tangential recess (51, 51′, 51″) in the outer surface of the shaft (21, 22).

A modular hoist drum is disclosed for use with a power shovel. The modular hoist drum may have a first outer body, a second outer body, and an anchor body that are hollow and generally cylindrical. The anchor body is connected between the first outer body and the second outer body. The anchor body may include an internal anchor configured to receive a ferrule.

Storage assemblies and bucket accessories for material-handling vehicles are provided. One assembly includes a storage compartment consisting of a planar shelf extending along the top edge of the bucket, a back wall extending upwardly from a rear edge of the shelf, and a pair of side walls that extend perpendicularly to opposite ends of the shelf and back wall. A pair of free-standing, elongated orientation rods project upwardly from the top of the back wall of the storage compartment. Tie-down straps at the end of the orientation rods are provided for securing material in both the bucket and the storage compartment. A pair of rack elements for supporting opposite ends of elongated items such as pipes may also be provided. One of the hooks may be secured to one of the orientation rods and the other hook may be secured to the roll bar of the vehicle.

A quick-coupler for coupling a tool, including a coupling mount for receiving a first locking part and a locking mount for receiving a second locking part, wherein a securing element, which can be actuated by a pressure medium, is associated with the coupling mount for capturing and/or securing the first locking part in the coupling mount and a locking element, which can be actuated by a pressure medium, is associated with the locking mount for locking the second locking part in the locking mount. The securing element of the coupling mount can likewise be actuated by the pressure circuit for actuating the locking element of the locking mount, with the securing element being connected to the pressure circuit via a switching valve which is controllable by a sensor arranged at the coupling mount for detecting the locking part.
