Failure of EWP Jib Ram Pin (updated)



At 13:20 on 4 August 2016, a Snorkel A46JRT EWP was being trammed near XP2 in the Northbound Tunnel. A failure of the jib ram stepped pin locking bolts occurred, causing the basket to tilt forward and strike the ground from a height of ~2.5 meters. At the time of the incident, one person (IP) was in the basket operating the EWP. The IP sustained contusions to the left hand, left lower arm and the right lower back as result from being thrown backwards against the basket.
