Case Study 88: Luffing Jib Collapse – Urban Construction Site (No Injuries)
Incident Overview
A luffing jib tower crane jib collapsed at a London development site. The site was unoccupied at the moment, avoiding injury, but it triggered emergency response and public safety controls.
What Went Wrong
Even when no one is hurt, this is a serious indicator: a collapse event means the system failed somewhere — inspection, configuration, weather planning, or structural integrity.
Key Lessons
“No injury” is not “no incident”
Near-miss collapses demand full investigation
Public interface changes everything
Safety Recommendations
Treat as a major incident. Secure area, preserve evidence, formal investigation, and review wind/erection/tie/inspection arrangements.
