High-riggers work 40–80 feet above the floor. A 2 lb shackle falling 60 feet hits with the same force as a 120 lb weight dropped 1 foot. The airspace above you is a deadly work zone.
Module briefing
01
The Up-Look Protocol
Required before entering ANY area with active overhead rigging.
1STOP the machine at the edge of the zone
2Look UP — scan the entire overhead area slowly
3Look for dangling hardware, loose motors, active riggers
4Confirm the drop zone is clear
5Radio or verbally confirm with the rigging lead that it's safe
6Only after confirmation — enter the zone
Core Drill· Core Drill — 15 seconds, every time
Stop at the edge, look up, confirm, proceed. It is mandatory and it is not negotiable when work is overhead.
Illustration · real fall timeHigh-riggers work 40–80 feet above the floor. A 2 lb shackle dropped from 60 ft arrives at 42 mph carrying 120 ft·lb — the Safety Engine's falling-object model, which reports energy and speed rather than force. The drop plays in real fall time.
02
Ground + Overhead Simultaneously
Sometimes a push crew is in your path WHILE riggers work above.
1Call "STOP" — halt all ground movement first
2Wait for the "STOP" echo from ground crew
3Confirm the 3-foot halo zone is clear around your machine
4Now do your Up-Look — scan above you
5Only after BOTH ground and overhead are confirmed clear do you proceed
Hard Rule· Never manage one hazard at a time
Clearing the ground while ignoring the sky (or vice versa) is how people get hit. Lock out, clear both, then move.
03
Sling Lifts on Bare Forks
Slings or chains choked around bare forks lift audio arrays and structures. The load swings freely — it is not rigid. Any movement causes a pendulum effect that constantly shifts the machine's center of gravity.
Slow ALL movements by at least 50%. No sudden starts, stops, or direction changes. Have a qualified rigger control the load with a tag line.
