Fire Department crews hurried to the top of a 60- to 70-foot crane in the Port of Long Beach to try to rescue a man in cardiac arrest Monday evening, according to a department spokesman.

A call about the medical emergency came in around 6 p.m., and rescue personnel rushed to the crane in the 300 block of Mediterranean Way, LBFD spokesman Capt. Jack Crabtree said.

Once rescuers got to the control area of the crane, they tried to revive the man in his 50s, but after “prolonged” efforts, they determined he was dead, Crabtree said.

As of 7:30 p.m., about 20 firefighters were using rope rigging to lower the man down, according to Crabtree. The Los Angeles County Coroner’s office was also at the scene and would be responsible for determining how the man died.
