Abstract
A cargo hook for releasably carrying a load includes a support frame, a load beam and latching mechanism for releasably engaging the beam in a load secured position. The latching mechanism includes a contact roller carried by the beam and an interference shaft rotatably mounted to the frame. In the load secured position, the roller abuts the interference shaft. Load release occurs when the interference shaft is rotated to a position which permits the load beam to pivot downwardly past the shaft.
