Rigging & Lifting
7 talks
A suspended load converts stored energy into a hazard that nobody can outrun, and the failure usually happens in the hardware nobody inspected rather than in the crane everybody watched. This bundle covers slings, hardware, lift planning and the exclusion zone underneath.
Rigging equipment for material handling is 29 CFR 1926.251, which sets the inspection duty and the requirement that rigging be inspected before each shift and as necessary during use. Cranes and derricks in construction are the whole of Subpart CC: 1926.1425 governs keeping clear of the load, 1926.1427 operator qualification, 1926.1417 operation, 1926.1424 the work area control zone, and 1926.1408 power line clearance. Material hoists and elevators are 1926.554.
Use this bundle before any lift, for sling and shackle inspection, for the conversation about who is allowed under a load, and for the planning that has to happen while the load is still on the ground. The recurring lesson is that the fall zone is wider than the shadow of the load.
Talks in this bundle
- Chain Hoist Safety
Why a manual hoist is designed for one person's effort, why a cheater bar silences an overload warning, and why a bent hook is evidence, not damage.
- Crane Lifting
OSHA 1926 Subpart CC requirements, power line clearances, why workers on foot are most at risk, and the roles that make a lift safe.
- Cranes and Suspended Loads
Why the fall zone is wider than the load's shadow, why the rule is nobody in it rather than nobody under it, and what the few exceptions require.
- Hoist and Winch Safety
Why a powered hoist has no human effort limit to warn you, why OSHA's rule points back to the manufacturer's manual, and why standing clear is law.
- Rigging Inspections
The two separate inspection regimes, the 12-month ceiling on chain sling inspections, the monthly record most sites skip, and the 125 percent proof test.
- Synthetic Sling Protection
Why a web sling's removal criteria are all pass/fail, why the damage hides inside an intact-looking cover, and why edge protection goes on first.
- Wire Rope Inspection
The three deficiency categories in OSHA 1926.1413, why one broken strand beats six broken wires, and why power-line contact can never be repaired.
Inspection checklists in this bundle
- Mobile Crane Operation Daily Inspection Checklist
The each-shift rule at 29 CFR 1926.1412(d): wire rope, hooks, hydraulics, outriggers, safety devices, rigging and the lift plan.
Frequently asked questions#
How often must rigging equipment be inspected?
1926.251(a)(1) requires rigging to be inspected before each shift and as necessary during use to ensure it is safe. Damaged or defective rigging must be removed from service immediately.
Can anyone work under a suspended load?
1926.1425 restricts who may be within the fall zone and when. The practical answer in the talks is narrower than the rule: the fall zone is bigger than people estimate, and it moves with the load.
What clearance is required from power lines during a lift?
1926.1408 sets the minimum approach distances for equipment operating near energised power lines, with the required distance depending on the line's voltage.
