## Narrative

Four employees were stowing the jib on a Link-Belt RTC 8090 crane and were on the platform of the crane.  The jib was not adequately stowed correctly; the crane operator telescoped the boom out, and the fly-tip head sheave was pushed towards and bent the front fly storage bracket.  This caused the jib to swing out violently, striking two of the four employees.
