A coupler includes first and second attachment pin jaws. A first latching mechanism is associated with the first jaw. The first latching mechanism has an arm connected to and extending away from a latching member. A second latching mechanism is associated with the jaw. The first and second latching mechanisms are adapted to latch the first and second attachment pins of an accessory in or on the first jaw and the second jaw, respectively. The second latching mechanism is powered for movement between a latching position and a non-latching position. The first latching mechanism is operatively connected to, or connectable with, the second latching mechanism to allow it to selectively operate the first latching mechanism between latching and non-latching positions by means of a groove or flange or finger on the second latching mechanism. A magnet is provided to ensure a correct disengagement of the first latch latching mechanism.
A coupler having a top half for attaching to an end of an excavator arm of an excavator and a bottom half for attaching to an accessory, the bottom half comprising first, front jaw and a second, rear jaw, at least one of the jaws featuring an associated latching mechanism for retaining an attachment pin of the accessory within the jaw, wherein one of the coupler, one or both of the jaws, and the associated latching mechanism further comprises, or is associated with, a magnet, the magnet configured for releasably engaging or holding a component of the locking mechanism in a predefined positional condition relative to one of the jaws or relative to another component of the latching mechanism.
A coupler having a top half for attaching to an end of an excavator arm of an excavator and a bottom half for attaching to an accessory, the bottom half comprising first, front jaw and second, rear jaw, each of the jaws comprising an associated latching mechanism for retaining an attachment pin of the accessory within the associated jaw, wherein the coupler further comprises a safety pin for securing at least one of the latching mechanisms in a latching state with respect to the associated attachment pin.
