How to Make a Bolted Connection
Connectors set steel quickly and safely by following a routine.
Quick answer
Connectors set steel quickly and safely by following a routine. In short: tie; guide; align, then complete the remaining steps below.
Step by step
Tie off to an approved anchor before the beam arrives.
Guide the beam into position as the crane operator follows your signals.
Align holes with a spud wrench or drift pin.
Install at least two bolts per connection, wrench tight, before the crane releases.
Release the load only when the connection is secure.
Complete remaining bolts and tighten to specification.
