Experts: Missing pins possibly caused Seattle crane collapse
SEATTLE (AP) — Experts say it appears workers who were disassembling a construction crane had removed pins securing sections together, and that could explain why it toppled over the weekend, killing four people.
Crane accident investigator Tom Barth said Monday based on videos of the Seattle crane collapse that “if the pins had been in, that crane would not have fallen over.”
The crane’s mast toppled Saturday afternoon as workers were taking it apart.
Sections landed on top of the new Google building where it had been used and on traffic below, striking six vehicles.
Two ironworkers on the crane were killed, as were two people in cars — a retired city employee and a college freshman. Four others were injured.
