Attachment assembly for clamping buckets and systems and methods thereof

A loader comprising:

• a frame coupled to a traction system configured to move the loader forward and backward;
• at least one lift arm having a first end coupled to the frame;
• a multipurpose bucket coupled to a second end of the at least one lift arm, the multipurpose bucket having a front jaw and a rear jaw, the front jaw being rotatable relative to the rear jaw about an axis;
• an actuator operatively coupled to the front jaw to rotate the front jaw relative to the rear jaw about the axis;
• an attachment assembly removably coupled between the front jaw and the rear jaw such that the attachment assembly is removable from between the front jaw and the rear jaw only responsive to control of the actuator to separate the front and rear jaws, the attachment assembly including:
• a pair of sidewalls spaced from each other in a first direction, and
• at least two structural beams spaced from each other in a second direction perpendicular to the first direction, each of the at least two structural beams having a length greater than a width, a first end fixed to a first sidewall of the pair of sidewalls, and a second end fixed to a second sidewall of the pair of sidewalls;
• and
• a working tool coupled to the attachment assembly such that a portion of the working tool extends below the attachment assembly,
• wherein each of the first sidewall and the second sidewall has:
• a first connection interface configured to be removably coupled between the front jaw and the rear jaw,
• an L-shaped retention arm configured to interconnect to a back surface of the rear jaw when the first connection interface is removably coupled between the front jaw and the rear jaw;
• an angled reaction arm arranged adjacent to a bottom surface of the front jaw when the first connection interface is removably coupled between the front jaw and the rear jaw;
• and
• a second connection interface configured to be coupled to the working tool,
• wherein, in a side view of the attachment assembly, the first connection interface and the L-shaped retention arm of each of the first sidewall and the second sidewall are separated by a first engagement slot, a bottom edge of the rear jaw being provided in the first engagement slot when the first connection interface is removably coupled between the front jaw and the rear jaw, and
• wherein, in the side view of the attachment assembly, the first connection interface and the angled reaction arm of each of the first sidewall and the second sidewall are separated by a second engagement slot, an inner edge of the front jaw being provided in the second engagement slot when the first connection interface is removably coupled between the front jaw and the rear jaw.
