Auto-Body Vehicle Lifting SWMS

Vehicle hoist operations in auto-body and mechanical workshops involve lifting passenger vehicles, light commercials and SUVs to working height using 2-post, 4-post or scissor hoists. Each lift cycle exposes technicians to fall-from-height risks for the load, crush injuries from uncontrolled descent, and plant failure consequences if locking mechanisms, hydraulic systems or load-bearing arms are not verified before and during use. Under WHS Regulation 2025, the operation of powered vehicle hoists constitutes high-risk plant work requiring a documented Safe Work Method Statement before the task commences. The SWMS must address load assessment against the manufacturer's rated capacity, correct jacking-point selection per the vehicle manufacturer's specification, mechanical safety lock engagement, and daily pre-operational inspection. This document provides the structured hazard identification, control selection and sign-on framework required for PCBUs operating workshops where hoist work is performed routinely.

Control measures

Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.

1. 1Elimination — Where service task permits (e.g. wheel removal only), use trolley jacks with axle stands at ground level rather than full hoist elevation to remove fall and crush exposure.
2. 2Elimination — Prohibit any work beneath a vehicle that is supported only by hydraulic pressure; the lift cycle is incomplete until mechanical safety locks audibly engage.
3. 3Substitution — Replace ageing single-point hydraulic hoists with twin-cylinder synchronised models incorporating automatic mechanical locking at multiple height intervals per AS/NZS 2550.9.
4. 4Engineering — Verify mechanical safety locks engage at the working height by lowering the hoist onto the locks before any technician moves under the vehicle.
5. 5Engineering — Use manufacturer-specified arm pad adaptors matched to vehicle jacking points identified in the OEM service manual or hoist manufacturer vehicle data chart.
6. 6Engineering — Install and maintain hydraulic over-pressure relief valves, anti-creep check valves and synchronised cable systems inspected per AS/NZS 2550.9 maintenance schedule.
7. 7Administrative — Complete the daily pre-operational hoist inspection checklist covering arms, pads, chains, locks, hydraulic lines and control box before first lift each shift.
8. 8Administrative — Verify vehicle gross mass against hoist rated capacity plate; refuse the lift for EVs or LCVs exceeding stated working load limit.
9. 9Administrative — Brief all workshop personnel on exclusion zones around hoist bays during raise and lower cycles; horn or verbal warning before activating controls.
10. 10PPE — Wear AS/NZS 2210.3 safety footwear with steel toecap, AS/NZS 1337.1 safety eyewear and cut-resistant gloves when handling lifting adaptors and inspecting underbody.

Applicable Codes of Practice

Worked example

At a suburban smash repair workshop, the leading hand runs the Monday pre-start brief at 7:30am before the team begins panel work on a recently delivered dual-cab ute. The technician assigned to the 2-post hoist bay opens this SWMS on the workshop tablet and walks through the hazard register with the apprentice. They confirm the ute's kerb mass against the hoist's 4-tonne rated capacity plate, then cross-reference the vehicle manufacturer's underbody diagram to identify the four reinforced jacking points. The apprentice signs onto the SWMS acknowledging the mechanical lock engagement step. During the lift, the technician raises the vehicle to working height, then deliberately lowers onto the safety locks until the audible click confirms engagement at both columns before either worker moves underneath. Mid-task, the apprentice notices a small hydraulic weep at the slave cylinder seal. Referring back to the SWMS control measure on hydraulic leaks, the technician immediately tags the hoist out of service, transfers the vehicle to an adjacent bay using stands, and logs the defect for the service technician. The SWMS sign-on sheet is updated with the control change and the team continues work without exposure to creeping descent. The document is filed in the workshop SWMS register at end of shift.
