Abstract

A bottom block assembly for an overhead crane includes a main bottom block, an outer frame carried by the main bottom block and rotatable relative to the main bottom block about a vertical axis of rotation, and a pair of paddles carried by the outer frame and downwardly extending from the outer frame on opposed sides of the main bottom block. Upper ends of the paddles are pivotably secured to the outer frame about horizontal axes so that lower ends of the paddles pivot toward and away from each other. The paddles are pivotable between a closed position wherein each of the paddles is substantially vertical and an open position wherein the lower end of each of the paddles is outwardly pivoted away from a vertical central axis. Each of the paddles has a keyhole-shaped closed-section opening near its lower end.
