Product Overview

Summary: This SOP sets out clear, practical requirements for demarcation and zoning at crane sites to keep people, plant and property safely separated from lifting operations. It provides a structured approach to planning, marking and controlling crane operating areas in line with Australian WHS expectations, helping businesses prevent struck‑by incidents, collisions and unauthorised access.

Demarcation and zoning are critical controls at any crane site, where loads are suspended, plant is moving and multiple trades are working in close proximity. Without clearly defined and enforced exclusion zones, public protection zones, loading areas and crane operating envelopes, the risk of serious injury from falling objects, slewing cranes or mobile plant interaction increases dramatically. This SOP provides a detailed, repeatable method for planning and implementing effective site zoning around tower cranes, mobile cranes, vehicle loading cranes and other lifting equipment used on Australian worksites.

The procedure guides businesses through assessing crane reach and load paths, identifying high‑risk interfaces with pedestrians, traffic and adjacent properties, and then translating those assessments into practical on‑the‑ground controls such as barriers, signage, spotters and traffic management. It supports compliance with WHS legislation and relevant Australian Standards by clarifying who is responsible for establishing, inspecting and maintaining zones, and how changes to crane configuration or site layout are to be managed. By adopting this SOP, organisations can demonstrate due diligence, improve coordination between crane crews and other contractors, and significantly reduce the likelihood of incidents that lead to injuries, property damage, project delays and regulatory scrutiny.

Key Benefits

• Reduce the risk of struck‑by and crushing incidents through clearly defined crane exclusion and no‑go zones.
• Ensure consistent, compliant demarcation practices across all crane sites and projects.
• Improve coordination between crane crews, other trades and traffic management through standardised zoning plans.
• Demonstrate due diligence with documented processes that align with Australian WHS legislation and standards.
• Minimise project delays and costly rework caused by unsafe access, site congestion and uncontrolled lifting areas.
