Product Overview

Summary: This Mobile Equipment Maintenance SOP sets out a clear, repeatable system for inspecting, servicing and repairing mobile plant and vehicles in line with Australian WHS requirements. It helps you control critical safety risks, extend asset life and demonstrate due diligence for everything from forklifts and loaders to site utes and light vehicles.

Mobile equipment such as forklifts, loaders, excavators, EWP’s, skid steers and site vehicles are often at the heart of Australian workplaces – and among the highest risk. Poorly maintained equipment can lead to loss of control, rollovers, fires, dropped loads and serious crush injuries. This Mobile Equipment Maintenance Safe Operating Procedure provides a structured, WHS-aligned approach to keeping mobile plant in safe working order, from daily pre-start checks through to scheduled servicing, defect reporting and out-of-service tagging.

The procedure helps businesses move away from ad‑hoc, operator‑dependent maintenance practices to a consistent, documented system that stands up to regulator and client scrutiny. It clarifies who is responsible for inspections, how defects are assessed and prioritised, and what controls must be in place before equipment is returned to service. By implementing this SOP, organisations can reduce unplanned downtime, prevent avoidable incidents, and show clear evidence that plant maintenance obligations under Australian WHS legislation are being actively managed.

This SOP is suitable for a wide range of industries including construction, manufacturing, warehousing, logistics, civil works, local government and mining support services. It is written in practical, plain language to support front-line supervisors and maintenance teams, while still providing the structure and traceability that WHS professionals and auditors expect.
