Preferably, a plurality of spaced apertures (27), (29), (31) are formed on each of the side frames (25a), those in one frame being transversely aligned with those in the other frames, and preferably also a plurality of spaced apertures (33, 35) and/or latching surfaces are formed on the latching hook or on an extension thereof, through or against which the locking pin (23) can be passed or can bear to prevent relative movement between the hook (17a) and side frames.

Abstract: An arm assembly for an excavator or the like includes a quick coupler integrated into an arm member and an implement link member, thus eliminating the need to connect a separate quick coupler to the arm. The arm member includes: (i) a proximal end adapted for connection to an associated boom for pivoting movement about a transverse pivot axis; (ii) a distal end, spaced from the proximal end along a first longitudinal axis; and, (iii) a first recess defined in the distal end. The first recess is defined about a first transverse axis that lies parallel to the transverse pivot axis and includes an open mouth and a closed inner end. The implement link member includes: (i) a first end; and, (ii) a second end spaced from the first end along a second longitudinal axis and defining a second recess about a second transverse axis parallel to the first transverse axis.
