Rigging and Lifting for Boilermakers
Heavy industrial rigging for boilermakers, followed through Ironbridge Industrial's heavy-lift crew on a refinery turnaround near Baton Rouge: the lift team and lift categories, vessel weights and centers of gravity, lugs, trunnions, slings and lifting beams, mobile crane load charts, crawler cranes and hydraulic gantries, ground bearing and crane mats, tandem lifts and upending, jacking and skidding, chain falls inside boilers, signals, wind and power lines, and critical lift planning, ending with a capstone coker drum set under OSHA's crane rules and ASME P30.1.

What you'll learn
- Describe how heavy rigging is organized on an industrial project, the roles of the lift team and the work boilermakers do below the hook
- Classify lifts as routine, planned or critical using percentage of chart and the other triggers in an owner's procedure, ASME P30.1 and OSHA's multiple-crane rule
- Build up the weight and center of gravity of a vessel or component from its parts, choose a contingency that matches the source, and use a trial lift to confirm them
- Explain how lifting lugs, trunnions and tailing lugs are designed and installed, and why out-of-plane loading reduces their capacity
- Calculate sling and lug loads for a load with an off-center center of gravity, and select slings, shackles, spreader bars and lifting beams for heavy loads
- Read a mobile crane load chart for a given configuration, without interpolating, deduct everything below the boom tip and find the percentage of chart
- Describe crawler cranes, heavy-lift attachments, tower cranes and hydraulic gantries, and calculate gantry leg loads against stage capacities
- Estimate outrigger loads, size crane mats against allowable ground bearing, and identify buried services and other ground hazards before a crane sets up
- Explain how load shares between two cranes, calculate the tail crane's load during upending, and apply the rules for tandem lifts
- Plan jacking, cribbing, skidding and rolling of heavy loads, including friction, slope and the margin for uneven jack loads
- Rig chain falls, lever hoists and wire rope pullers inside boilers from approved rigging points, calculate angled chain tensions and transfer loads safely
- Give and follow crane signals by hand and radio, account for wind on large loads and keep cranes outside OSHA's power line clearances, and prepare, review and carry out a critical lift plan
