Abstract

See full text

A crane hook rotation-limiting device includes a mounting base and a plunger extending through a hole formed in the mounting base so as to be movable with respect to the mounting base. A spring first bearing portion is connected to the plunger so as to be movable with the plunger. A spring second bearing portion is positioned opposite the spring first bearing portion so as to be fixed with respect to the plunger during movement of the plunger. A spring member extends between the spring first bearing portion and the spring second bearing portion. A pair of crane hook rotation-limiting devices as described herein may be mounted to a crane hook assembly to control rotation of the crane hook during movement of the hook when the hook supports a sling spreader or a sling spreader and a die (or other item of tooling).
