Abstract
A choker hook has a main body and a latch member rotatable relative to the main body. The latch member is biased by a spring thereby to form a pocket to hold the ferrule of a choker cable used in logging operations. The latch member has a toe piece which contacts the surface of a log when the choker hook is rotated by the choker cable relative to the log. The force between the toe piece and its attached latch member will tend to rotate the latch member relative to the main body when the effect of the force on the choker hook is such that the toe piece is brought into contact with the outside of the log. The ferrule pocket will open and the ferrule and attached cable will be released thereby releasing the log being transported without manual intervention at the point of log release.
