Abstract

The coupler has a pair of spaced side frames ( 25 a) in each of which a first hook like aperture ( 13 ) is provided for engagement with a first pivot pin provided on an excavator bucket and wherein a locking pin ( 23 ) is moveable from and into a locking position in which it prevents the latching hook ( 17 a) from disengage from a second pivot pin ( 9 a), ( 9 b) or ( 9 c) on the bucket there being a plurality of locking positions for the pin to accommodate different buckets. Preferably, a plurality of spaced apertures ( 27 ), ( 29 ), ( 31 ) are formed on each of the side frames ( 25 a), 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 ( 17 a) and side frames. Preferably, the piston end cylinder device ( 19 a) for operating the latching hook has a much longer stroke than usual and the side frames ( 25 a) of the coupler are longer than those of known couplers, there being a downwardly opening recess ( 15 a) in the side frames which is much wider than usual to accommodate different pin spacings on the buckets of different manufacturers.
