ABSTRACT:
A safety attachment for a lifting hook comprises a handle attached to the hook at one leg of the hook and a trigger pivotally mounted on the handle and operable such that the latch of the hook is pulled open by operating the trigger. The handle comprises a bar generally parallel to the one leg of the hook with the trigger being pivotally mounted adjacent a bottom end of the bar and extending in front of the bar for grasping by the hand simultaneously with the bar. A wire loop extends between a top of the trigger and a part of the latch and passes around both sides of the one leg of the hook. The handle and trigger allow the hook to be manipulated and operated by the user without touching the hook in the area of the heavy object to be engaged onto the hook.
