In one position, the channel is open for permitting entry and removal of the pin and in other positions is closed to lock the pin from exiting. Coupling includes another pin receiving slot so that a second pin of the work implement may be received.
The slot and the channel of the rotator in the open position are inclined relative to one another. The crank in one embodiment has a number of projections for cooperating with elements of a hand operated lever to drive the rotator.
When the hand operated lever is not in use, it may be stored conveniently within the coupling to serve as a locking device. In another embodiment the crank is connected to the output rod of the hydraulic cylinder. |
