Case Study 22: Multiple Cranes Operating Without Proper Coordination
Incident Overview
Four cranes were operating simultaneously on a congested construction site.
What Went Wrong
No coordinated lifting plan was in place, leading to overlapping slewing radius and confusion between
teams.
Key Lessons Learned
- Multiple crane sites require coordination
- Overlapping radius increase collision risk
- Clear leadership is essential
Safety Recommendations
Introduce a coordinated lifting plan and appoint a single point of control when multiple cranes operate
on one site.
●LOLER: Reg 8
●PUWER: Reg 8/9 , training for coordination
●BS 7121: Part 1 (planning/control), plus crane-type parts (2 mobile / 3 tower) re: zoning/anti-collision/coordination methods
