Product Overview

Summary: This procedure sets out a clear, step-by-step method for correctly interpreting and applying crane load charts on Australian worksites. It helps operators, doggers and supervisors make safe lifting decisions, prevent overloading, and demonstrate compliance with WHS and plant safety requirements.

Incorrect use of crane load charts is a leading contributor to crane incidents, near misses and costly project delays across Australian worksites. This Crane Load Chart Utilisation Safe Operating Procedure provides a practical, field-ready framework for selecting the correct chart, reading it accurately, and applying it consistently to every lift. It guides workers through critical considerations such as crane configuration, radius, boom length, outrigger/stabiliser setup, ground conditions, wind, and dynamic loading so that the safe working load is never exceeded.

Developed for Australian conditions and WHS expectations, this SOP helps businesses demonstrate due diligence in the planning and execution of lifting operations. It standardises how operators, doggers and supervisors communicate about capacities, confirms that the right load chart is being used for the actual crane setup, and documents the decision-making process for complex or non‑standard lifts. By embedding this procedure into your lifting operations, you reduce the likelihood of crane overturns, structural failures and load drops, while improving productivity through clearer planning and fewer disputes about what the crane can safely lift.

The document is designed to integrate with existing lift plans, pre-start checks and permit-to-work systems. It supports competency-based training, toolbox talks and verification of competency (VOC) processes, giving your teams a consistent reference that aligns with Australian Standards and regulator expectations.

Key Benefits

• Ensure cranes are operated strictly within rated capacities by correctly interpreting and applying load charts.
• Reduce the risk of crane overturns, structural failures and dropped loads through standardised decision-making.
• Demonstrate compliance with Australian WHS legislation, plant safety requirements and relevant crane standards.
• Improve coordination between crane operators, doggers, riggers and supervisors with a common process and language for discussing capacities.
• Support training, competency assessment and incident investigation with a documented, repeatable utilisation procedure.

Who is this for?

• Crane Operators
• Doggers and Riggers
• Site Supervisors
• Construction Project Managers

Hazards Addressed

• Crane overturning due to overloading or excessive operating radius
• Structural failure of booms, jibs or components from exceeding rated capacity
• Dropped loads causing struck-by injuries or property damage
• Instability from incorrect outrigger or stabiliser configuration
• Crane collision with structures, services or other plant due to misjudged radius or configuration
• Ground failure or subsidence under outriggers from underestimating load distribution
• Operator error arising from misreading or using the wrong load chart
• Increased risk during high wind or adverse weather conditions when environmental factors are not accounted for
