Course outline
16 modules
Advanced scope and professional judgment
Advanced rigging preparation begins where a familiar basic arrangement no longer explains the forces, stability or execution.
Weight uncertainty and configuration control
An advanced calculation must represent the actual configuration and the uncertainty in its data.
Composite centers of gravity and reference frames
A composite center of gravity is found from weighted coordinates in a common reference frame: x-bar = sum of Wi xi divided by sum of Wi, with an equivalent expression for y and z.
Lifting points and structural interfaces
The attachment interface can govern the entire rigging system.
Unequal reactions and multileg systems
For an ideal rigid beam with two vertical supports at x=0 and x=L and a total load W acting at x, static reactions are Rright=W x/L and Rleft=W minus Rright.
Force components and angle conventions
A sling force has vertical and horizontal components.
Specialty devices and application limits
Clamps, grabs, magnets, vacuum devices, lifting eyes and other specialty devices are rated for defined applications.
Beams, spreaders, equalizers and support systems
A lifting beam typically carries substantial bending; a spreader arrangement commonly uses compression in the member with tensioned upper rigging.
Rope, reeving, terminations and mechanical advantage
Ideal mechanical advantage compares load motion and effort in a defined reeving arrangement.
Dynamics, wind and unintended forces
Static equilibrium describes a load without acceleration; starting, stopping, impact, snagging and sudden release can change forces.
Level lifts, balance and load-transfer stages
Keeping a load level is a geometric and load-distribution problem, not just equalizing sling lengths by eye.
Rotation and upending preparation
Rotation changes geometry continuously.
Complex lifts and escalation
Multiple-crane lifts, personnel hoisting, offshore or subsea operations, blind transfers and critical-lift categories involve additional requirements and specialized competence.
Lift-plan participation and independent checking
A reviewable plan connects load data, calculations, drawings, equipment configuration, route, support conditions, personnel controls, communications and sequence.
Advanced inspection and failure investigation boundaries
Repeated defects can reveal misuse, incompatible geometry, harsh service or a system problem.
Capstone, practical evidence and defined scope
The advanced capstone is a training-only review of controlled data.
Assessment and completion
Requirements stay explicit.
Assessment plan: 48-question protected draft review form; 80% and all presented critical items correct. Two initial attempts with controlled remediation/reset. 192 draft bank items; no official external exam or credential.
Questions
Frequently asked
Is this an official OSHA or third-party certification?
No. IM Academi will identify the course provider and the exact completion outcome. It will not imply OSHA authorization, regulatory qualification, or another organization's certification unless the applicable authorization has been obtained and documented.
Does my employer still need to provide site-specific training?
Often, yes. Site hazards, procedures, equipment, emergency plans, supervision, and role authorization remain employer responsibilities. This page states course-specific boundaries but cannot replace an employer's hazard assessment.
What happens if a practical component is required?
The knowledge portion and practical evaluation are tracked separately. Final completion depends on the published course rules and a documented evaluation by an approved evaluator.
