Abstract

See full text

A quick coupler and methods of coupling and decoupling a quick coupler and work tool are disclosed. The quick coupler includes a frame, cylinder, primary blocking member, secondary blocking member, biasing member, and controller. The method of coupling includes activating an AUTOMATIC LOCKING state, automatically locking a second tool pin within a hook, a first tool pin entering a notch, and activating a LOCKED state. The method of decoupling includes activating the AUTOMATIC LOCKING state, resting the work tool on a surface, activating an UNLOCKED state, and separating the quick coupler and work tool. Advantageously, the quick coupler can automatically lock the second tool pin without actuation of the cylinder.
