Product Overview

Summary: This Belt and Pulley Alignment Safe Operating Procedure sets out a clear, step-by-step method for safely aligning belt-driven systems on Australian worksites. It helps prevent mechanical failures, contact with moving parts, and unexpected downtime, while supporting compliance with WHS duties for plant and equipment.

Belt and pulley systems are critical to the safe and reliable operation of conveyors, pumps, fans, compressors and other rotating plant across manufacturing, mining, agriculture and facilities environments. Poor alignment dramatically increases the risk of belt failure, pulley damage, excessive vibration and heat build-up, which can lead to fires, unplanned shutdowns and serious injuries from entanglement or ejected components. This Belt and Pulley Alignment Safe Operating Procedure provides a consistent, WHS-focused method for inspecting, isolating and aligning belt-driven equipment so that tasks are carried out safely and to a repeatable standard.

The SOP walks workers through lock-out/tag-out, guarding requirements, verification of zero energy, and the correct use of alignment tools such as straightedges, laser alignment kits and tension gauges. It defines responsibilities, required competencies, and documentation requirements, helping organisations demonstrate due diligence under Australian WHS legislation. By embedding this procedure into your maintenance program, you reduce the likelihood of mechanical incidents, extend asset life, and give supervisors confidence that alignment work is being done safely, efficiently and in line with recognised good practice.

Key Benefits

• Reduce the risk of entanglement, crush injuries and contact with moving parts during belt and pulley maintenance.
• Extend equipment life by ensuring correct alignment, reducing vibration, heat build-up and premature belt or bearing failure.
• Ensure consistent, auditable alignment practices across shifts, contractors and multiple sites.
• Support compliance with WHS plant and equipment requirements by documenting isolation, guarding and inspection steps.
• Minimise unplanned downtime and production losses caused by belt tracking issues, slippage or catastrophic failure.
