Abstract
A breakaway bail for a pedestal mount crane pivotally attached to the gantry by a pin extending through bushings secured to a pair of parallel plates with a spacer between the plates aligned with the bushings. A beam having an upright flange is secured between the plates and a multiple sheave pulley is attached to beam by brackets. Each of the plates has a necked down section between the flange and the spacer to create a high stress area, which area will separate under overload conditions without affecting the connection of the crane to its pedestal.
