Advanced Rigging (RA) study plan

Compute tension in two-leg and four-leg bridle slings at 30, 45, and 60 degree horizontal angles, and state the multiplier rule for each angle from memory.

Calculate load center of gravity for asymmetric, multi-point pickups and predict which sling leg carries the greater share of the load.

Derive required sling capacity from a known load weight using the load-angle factor, and convert between SWL, WLL, and breaking strength using the applicable design factor.

Solve at least 20 worked problems covering share-of-load distribution across three- and four-point lifts with uneven leg lengths.

Explain how vertical, choker, and basket hitch configurations change rated capacity, and compute the effective capacity for each hitch type given a sling's vertical rating.

Identify the components and inspection points of shackles, hooks, swivels, turnbuckles, and eyebolts, and match each to its rated load marking convention.

Calculate the reduced capacity of a lifting eye or eyebolt loaded at an angle off its rated axis.

Select the correct below-the-hook device type for a load with a specified geometry, weight, and pick point arrangement.

Compute sling tension and hardware loading for multi-leg slings with unequal leg lengths and off-center pick points.

Distinguish wire rope construction variables (lay direction, strand pattern, core type) and state how each affects flexibility, abrasion resistance, and rotation resistance.

Identify the mechanisms of wire rope degradation and classify severity against removal-from-service thresholds for broken wires, diameter reduction, and corrosion.

Demonstrate and describe four knots and two splices appropriate to synthetic rope rigging, and state the strength loss associated with each.

Recite standard hand signals for hoisting, lowering, stopping, emergency stop, and boom motions, and identify which signal overrides all others.

Describe the roles and legal responsibilities of the signalperson, rigger, operator, and lift director, and explain the chain of command during a lift.

Explain the requirements for a qualified rigger and qualified signalperson and how qualification differs from certification.

Summarize the key provisions of the applicable sling and rigging standards, including design factors, periodic inspection intervals, and recordkeeping duties.

Analyze three accident case patterns and identify the specific procedural or communication failure that caused each.

Calculate the required jacking force and select jack capacity for a load of given weight, including the safety margin and the effect of off-center loading.

Compute the force needed to move a load on rollers or skids, accounting for rolling resistance, friction coefficient, and the slope of the travel path.

Design a jack-and-block sequence for a load that must be raised in stages, specifying cribbing size, bearing area, and load transfer points.

Explain how to verify ground bearing pressure under cribbing and predict the failure mode when bearing capacity is exceeded.

Plan a controlled skidding move including pull-point location, anchor capacity, and load restraint during travel.

Classify a lift as critical or non-critical against defined criteria and justify the classification in writing.

Draft a critical lift plan containing load weight and center of gravity, rigging arrangement, capacity utilization, ground conditions, and contingency provisions.

Calculate percent capacity utilization for a crane configuration and determine whether the lift falls within acceptable limits.

Identify the failure modes of a lift plan: unaccounted dynamic loading, wind area, two-blocking, and swing path interference.

Sequence load movement for a rotation or tailing operation and predict how the load path changes as the center of gravity shifts.

Apply removal-from-service criteria to slings, shackles, hooks, and wire rope, and decide pass or fail for 15 given condition descriptions.

Build an inspection schedule distinguishing frequent from periodic inspection and state who may perform each.

Describe the documentation requirements for inspections, including what must be recorded, retained, and made available.

Explain the effect of environmental and service factors (heat, chemicals, UV, abrasion, shock loading) on service life and inspection frequency.

Re-solve a mixed set of load calculation and sling capacity problems under time pressure to confirm retention of the heaviest domain material.

Integrate math, hardware, planning, and regulatory content in two full-length practice exams and score each against a target pass threshold.

Identify the three weakest sub-topics from practice exam results and remediate each with focused review and re-testing.

Assemble a consolidated final reference sheet covering formulas, capacity factors, signal conventions, and removal criteria.
