Rigging operations sit at the heart of some of the most high-risk activities in construction, mining, oil & gas, and heavy industry. As riggers progress from basic to intermediate and advanced levels, the complexity of tasks increases — and so does the potential for costly and dangerous mistakes.
While experience reduces risk, it doesn’t eliminate it. Many incidents on Australian worksites occur not because workers lack licences, but because of complacency, poor planning, or gaps in advanced rigging knowledge. Understanding common mistakes — and knowing how to correct them — is essential for maintaining safety, compliance, and professional credibility.
This guide breaks down the most frequent rigging errors made at intermediate and advanced levels, explains why they happen, and shows how proper training and structured procedures can prevent them.
1. Incorrect Load Assessment and Weight CalculationsThe Mistake
One of the most common and dangerous rigging errors is misjudging the load weight or centre of gravity. At intermediate and advanced levels, loads are often irregular, dynamic, or partially suspended — making visual estimation unreliable.
Why It Happens
Assumptions based on previous lifts
Failure to consult load charts or engineering drawings
Inaccurate interpretation of lifting plans
Overconfidence from prior experience
How to Fix It
Every lift must begin with verified load data. This includes:
Confirming load weight using manufacturer specs or engineering documentation
Identifying the true centre of gravity
Accounting for dynamic forces, wind load, and load shift
Structured training reinforces these fundamentals. Programs such as those outlined in Everything about Licence to Perform Rigging Intermediate Level explain how load calculations evolve as rigging complexity increases.

2. Improper Selection or Use of Rigging EquipmentThe Mistake
Using the wrong sling type, shackle size, or lifting gear configuration is a frequent cause of near misses and equipment failure at higher rigging levels.
Why It Happens
Misunderstanding working load limits (WLL)
Ignoring sling angles and tension multipliers
Using worn or incompatible equipment
Time pressure on site
How to Fix It
Rigging equipment selection must always be:
Rated for the load and lift configuration
Inspected before each use
Matched correctly to lifting points
Intermediate and advanced rigging training places strong emphasis on equipment compatibility, inspection standards, and load distribution — skills essential for complex lifts involving multiple slings or cranes.
3. Poor Lift Planning and Sequence ErrorsThe Mistake
Advanced rigging often fails not during the lift itself, but during poorly planned lift sequences. This includes incorrect lift order, insufficient clearance planning, or failing to account for environmental changes mid-lift.
Why It Happens
Rushed lift plans
Inadequate consultation with crane operators and supervisors
Failure to review site-specific hazards
Lack of contingency planning
How to Fix It
Effective lift planning includes:
Detailed lift plans reviewed by all involved parties
Clear step-by-step sequencing
Defined roles and communication protocols
Contingency procedures for unexpected changes
Advanced rigging licences specifically train candidates to manage multi-stage lifts and complex sequencing under real-world site conditions.
4. Communication Breakdowns During LiftsThe Mistake
Miscommunication between riggers, crane operators, and doggers remains a leading cause of incidents — particularly during complex lifts requiring multiple personnel.
Why It Happens
Inconsistent hand signals
Poor visibility
Lack of a single lift controller
Noise or environmental interference
How to Fix It
To prevent communication failures:
Assign one designated lift controller
Use standardised hand signals and radios
Conduct pre-lift briefings
Stop the lift immediately if communication is compromised
Intermediate rigging training reinforces communication hierarchy, while advanced rigging expands this to include multi-crane coordination and complex site environments.
5. Inadequate Inspection of Rigging Gear and Anchor PointsThe Mistake
Skipping or rushing equipment inspections — especially anchor points and temporary structures — can lead to catastrophic failure.
Why It Happens
Over-reliance on previous inspections
Time constraints
Failure to recognise subtle wear or deformation
Poor understanding of inspection criteria
How to Fix It
Rigging inspections must include:
Visual and tactile checks of slings, shackles, and hardware
Verification of anchor point ratings
Inspection of structural integrity where loads are transferred
Formal training ensures riggers understand inspection tolerances, rejection criteria, and documentation requirements, which are critical at intermediate and advanced levels.
6. Underestimating Environmental and Weather ConditionsThe Mistake
Wind, rain, uneven ground, and temperature changes significantly impact rigging safety — yet they are often underestimated.
Why It Happens
Pressure to complete lifts on schedule
Inexperience with dynamic load behaviour
Failure to reassess conditions during long lifts
How to Fix It
Environmental controls should include:
Wind speed monitoring
Ground stability assessments
Adjusted lift plans based on weather forecasts
Authority to postpone lifts when conditions become unsafe
Advanced rigging training prepares workers to adapt lifting strategies in real time while maintaining compliance.
7. Overconfidence After Gaining ExperienceThe Mistake
Ironically, one of the biggest risks at advanced levels is complacency. Experience can lead to shortcuts, skipped checks, and assumptions.
Why It Happens
Repetition of similar lifts
Familiarity with site conditions
Reduced perceived risk
How to Fix It
The solution is a disciplined, procedural mindset:
Treat every lift as unique
Follow documented procedures without exception
Encourage peer checks and safety culture
Continuous professional development — including upgrading from intermediate to advanced rigging — helps reinforce best practices and reset safety awareness.
8. Failing to Upgrade Skills When Job Scope IncreasesThe Mistake
Many riggers perform advanced-level tasks while holding only intermediate certification, exposing themselves and employers to legal and safety risks.
Why It Happens
Misunderstanding licence scope
Employer pressure
Lack of awareness of regulatory requirements
How to Fix It
Rigging work must always align with the correct licence level. As tasks increase in complexity — such as dual-crane lifts, suspended scaffolds, or complex structural rigging — upgrading certification becomes essential.
Intermediate rigging serves as the foundation, but advanced work requires advanced training and assessment.
Why Proper Training Is the Ultimate Solution
Most rigging mistakes are not due to negligence — they stem from knowledge gaps, insufficient training, or working beyond licence scope. Structured training provides:
Clear understanding of legal responsibilities
Hands-on practice under controlled conditions
Assessment aligned with WHS requirements
Confidence to manage high-risk lifts safely
If you are already certified at intermediate level, upgrading your skills reduces risk and increases employability. If you are new to complex rigging, starting with structured intermediate training is essential.
