The Chassis Aligner Safe Operating Procedure (SOP) provides detailed instructions and safety measures to help operators use a chassis aligner safely.
It covers the hazards (pushing and pulling, falling loads, a puller or clamp detaching, manual handling and poor housekeeping), the pre-operational inspection, operator training, the steps to plan and make a pull, and maintenance under lockout/tagout.
A hazard checklist for powered non-mobile plant, with Y, N and NA for each item, helps confirm every safety measure is in place before use.
