Rigging and Lifting Operations Course

Lesson 1 • Industry Terminology and Scope

Defines rigging and lifting terms used across industries and job roles. Shared vocabulary enables accurate communication with engineers, supervisors, and inspectors.

Lesson 2 • Hazard Identification and Risk Assessment

Teaches systematic identification of lifting hazards and structured risk-ranking methods. Risk assessment outputs drive control selection throughout all subsequent chapters.

Lesson 3 • Physics of Load and Force

Covers center of gravity, load distribution, and mechanical advantage as applied to lifting. Understanding these forces prevents overloading and equipment failure.

Lesson 1 • Slings: Types and Ratings

Covers chain, wire rope, synthetic web, and round slings with their rated capacities. Sling selection directly affects load security and equipment longevity.

Lesson 2 • Equipment Inspection and Rejection Criteria

Establishes pre-use and periodic inspection procedures with clear rejection criteria for all hardware. Systematic inspection prevents catastrophic failure from worn or damaged components.

Lesson 3 • Shackles, Hooks, and Connectors

Details screw-pin, bolt-type, and safety shackles alongside hook types and swivel connectors. Correct connector selection prevents unintended release under load.

Lesson 4 • Wire Rope and Fiber Rope

Examines construction, grades, and working load limits of wire and fiber ropes. Proper selection prevents rope failure under dynamic and static loads.

Lesson 1 • Crane Safety Devices and Limits

Reviews anti-two-block devices, load moment indicators, and boom angle indicators. Understanding device functions allows operators and riggers to respond correctly to alarms.

Lesson 2 • Reading and Applying Load Charts

Teaches interpretation of manufacturer load charts including radius, boom length, and configuration variables. Accurate chart reading is the primary safeguard against crane overload.

Lesson 3 • Tower and Overhead Cranes

Covers fixed and traveling tower cranes and overhead bridge cranes used in construction and manufacturing. Each type has unique setup, slewing, and load path considerations.

Lesson 4 • Crane Setup and Ground Bearing

Addresses site preparation, outrigger deployment, and ground bearing pressure calculations. Improper ground support is a leading cause of crane tip-over incidents.

Lesson 1 • Practical Load Calculation Exercises

Applies all formulas to realistic scenarios including structural steel, pipe bundles, and machinery. Scenario practice builds calculation speed and confidence before field application.

Lesson 2 • Applying Safety Factors

Defines design factor, working load limit, and proof load and shows how each applies to rigging selection. Safety factors provide the margin between rated capacity and failure load.

Lesson 3 • Two-Leg and Multi-Leg Sling Loads

Calculates load per leg for two-, three-, and four-leg sling arrangements under various angles. Multi-leg calculations account for unequal load sharing in asymmetric lifts.

Lesson 4 • Sling Angle Fundamentals

Explains how horizontal sling angle increases tension in each leg beyond the load weight. This relationship is the most critical calculation in rigging practice.

Lesson 1 • Crane and Equipment Selection

Guides selection of crane type, capacity, and configuration based on load weight, radius, and site constraints. Correct selection ensures adequate capacity with acceptable ground loading.

Lesson 2 • Tandem and Multi-Crane Lifts

Addresses load sharing, communication protocols, and synchronization requirements for tandem crane operations. Tandem lifts require engineered plans and dedicated lift directors.

Lesson 3 • Lift Classification Systems

Distinguishes routine, critical, and engineered lift categories based on risk and complexity criteria. Classification determines the level of planning, approval, and supervision required.

Lesson 4 • Site Survey and Obstruction Analysis

Covers pre-lift site surveys including overhead utilities, underground services, and structural constraints. Survey findings directly shape crane positioning and travel path decisions.

Lesson 1 • Radio and Electronic Communication

Covers radio protocol, channel discipline, and backup communication plans for lifting operations. Clear radio procedure prevents misunderstood commands during critical lift phases.

Lesson 2 • Signal Person Qualifications

Defines qualification requirements, responsibilities, and authority of the designated signal person. Only qualified signal persons may direct crane movement during lifting operations.

Lesson 3 • Communication Failure Protocols

Establishes procedures when communication is lost or signals are misunderstood during a lift. Immediate stop and verification protocols prevent accidents from miscommunication.

Lesson 1 • Pre-Lift Briefing and Toolbox Talk

Structures the pre-lift meeting covering roles, hazards, signals, and abort criteria for all crew members. Briefings align the team before any hook-up begins.

Lesson 2 • Tag Line Control and Load Stability

Teaches tag line attachment, positioning, and tension management to control load rotation and swing. Effective tag line use protects personnel and structures from uncontrolled loads.

Lesson 3 • Hook-Up and Rigging Attachment

Details correct attachment of slings, shackles, and hooks to the load and crane hook. Proper hook-up sequence prevents load shift and hardware disengagement.

Lesson 4 • Adverse Conditions and Lift Suspension

Addresses wind, visibility, and ground condition thresholds that require suspending or aborting a lift. Recognizing abort triggers is a critical competency for all rigging personnel.

Lesson 1 • Root Cause Analysis Methods

Introduces fault tree analysis, the five-whys method, and fishbone diagrams for lifting incidents. Root cause methods reveal systemic failures beyond immediate human error.

Lesson 2 • Corrective Action Development

Guides development of corrective actions tied to root causes with assigned owners and completion dates. Effective corrective actions address systems, not just individual behavior.

Lesson 3 • Lessons Learned and Knowledge Sharing

Establishes processes for distributing incident lessons across crews, sites, and organizations. Shared lessons prevent recurrence of the same failure modes across the workforce.

Lesson 4 • Incident Classification and Reporting

Defines near-miss, first-aid, recordable, and catastrophic incident categories with reporting timelines. Accurate classification ensures appropriate response and regulatory notification.
