Abstract: A quick hitch coupler having an arrangement for releasably coupling a tool such as an excavator tool to the quick hitch coupler. The arrangement for releasably coupling the tool to the quick hitch coupler has tool pin engaging members on spaced apart portions of the main body of the quick hitch coupler. One of the tool pin engaging members has an associated latching member movably mounted on the main body of the quick hitch coupler between a tool pin locking position and a tool pin releasing position. The latching member has a lock movably mounted on the latching member for locking a tool pin onto the latching member quick hitch coupler in normal use.

Abstract: Excavator tool quick attachment device (1) is used to attach a tool to a dipper arm (2) of an excavator. Body member (52) has two receivers (12,14) for tool pins (11,15). Receiver (12) has a movable latch (3) powered by an hydraulic ram (20) for securing and releasing pin (11) and receiver (14) has a movable spring loaded lock (22) for securing and releasing pin (15). A control assembly (21) is connected between latch (3) and lock (22) but only operates to release lock (22) when the device (1) is inverted relative to a normal working position and the hydraulic ram (20) is activated.
