HITACHI CRANE RELOCATION IN LOS ANGELES

Project Summary

To make room for new 4-th generation container cranes, a 25 year old Hitachi container crane needed to be relocated from one pier to another pier, both within Los Angeles port limits. The 800 t heavy crane was lifted off its rails using dollies. Propulsion was provided by two winch trucks. The 300 x 90 x 22 ft cargo barge NEHALEM was chartered for the move. Steel bridge pieces spanned the gap between the barge stern and the quay. On March 19, 1997, with incoming tide, the crane was rolled onto the barge and temporary secured to the deck. Next day, at the end of the outgoing tide, the crane was safely rolled off the barge and lowered onto its rails at the new pier.
