Structural steel erection: energy sources and direct controls

Erecting structural steel combines crane lifts, work at height, heavy sections being landed and bolted, and grinding and welding.

High-energy check

Every steel section on the hook exceeds the 1500 J trigger. Partially bolted connections and unsecured sections are the main release points.

Trigger checks

Mechanical
Moving parts, tools, tension, rotation or stored mechanical force.
Sound
Harmful noise or impulse sound.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

Sections are released from the crane only after the minimum bolting is achieved.
Erectors are attached to planned anchor points at all times.
The area below the erection face is excluded.
Loose items are removed from steel before it is lifted.
Tag lines control every section during landing.
Stop if wind exceeds the limit in the lift plan.

For your SPA or pre-start

State the section masses and lift plan, the minimum bolting before release from the crane, the fall protection for erectors and the exclusion below.
