Abstract
An improved safety latch suitable for use on grab as well as other types of lifting hooks. A hollow, generally rectangular, annular latch member surrounds the heel of the hook with the side walls of the latch member providing an L-shape configuration. The latch member is mounted on the heel of the hook for rotation about an axis extending transversely of the hook at the end of the foot of the L-shape configuration. The foot of the L-shape configuration has a length greater than the width of the throat of the hook and resilient means are provided for urging the latch member to rotate about the mounting axis to cause the leg of the L-shape configuration to extend across the throat of the hook whereby the end of the latch member at the foot of the L-shape configuration is adjacent the tip of the hook when the other end of the latch member is in contact with the exterior surface of the basket portion of the hook.
