High Risk Work Licence - Reach Stacker (RS) common mistakes
High Risk Work Licence - Reach Stacker (RS) · Understand the traps and how to avoid them.
When asked about the legal framework, the candidate lists only the WHS Act and omits the WHS Regulations, the relevant COP (e.g. Managing Risks of Plant in the Workplace), and the specific reach stacker standard (AS 2550.1 / AS 2550.4 / AS 2359 series) that apply to the plant.
Candidates memorise a single Act name and treat 'legislation' as one item, because the hierarchy of Act → Regulations → COP → Standards is not reinforced during training.
What to do instead
Build a one-page hierarchy card: Act (duties), Regulations (specific obligations, e.g. plant registration, high risk work licensing), COP (how to meet the duty), Australian Standards (technical detail). Practise naming at least one obligation from each level for a reach stacker scenario.
On a hazard/risk question the candidate identifies the hazard (e.g. 'uneven ground') but stops there and does not apply the risk management process - no likelihood/consequence rating, no hierarchy-of-control selection, and no residual risk review.
Training often focuses on spotting hazards, so candidates answer with a list rather than a structured risk assessment.
What to do instead
Use a fixed four-step template for every answer: identify → assess (likelihood × consequence) → control using the hierarchy (eliminate, substitute, engineer, administrate, PPE) → monitor and review. Practise writing a 3-line risk assessment for five common reach stacker tasks.
The candidate explains stability only in terms of the load moment and ignores the reach stacker's variable geometry - boom luffing, spreader extension, and the fact that capacity changes with boom angle, radius and attachment (e.g. intermodal vs. piggyback spreader).
Candidates transfer forklift stability knowledge (simple load centre) to a machine whose load chart is multi-variable, and they have not practised reading the actual chart for the machine.
What to do instead
Work through the manufacturer's load chart for the specific machine: plot capacity against radius at several boom angles, note the effect of spreader type and of wind on tall stacks, and state the rule that the chart capacity is a maximum never to be exceeded - not a target.
During the pre-start inspection the candidate walks around the machine but does not actually function-test the safety devices - the overload indicator, the boom-luff lock, the spreader twistlock indicators, the level indicator, the horn and the reversing alarm - and does not record defects in the maintenance log.
Pre-start checks are treated as a visual tick-box, and candidates are unsure which items are 'test' versus 'look'.
What to do instead
Memorise a pre-start sequence grouped by system (tyres/wheels, brakes, steering, hydraulics, boom and spreader, safety devices, fluids/leaks, cab and mirrors) and state for each item whether it is a visual check or a functional test. Always finish with 'any defect is recorded and reported, and the machine is tagged out if it affects safe operation'.
When planning the operating area the candidate talks about traffic management generally but omits the reach stacker specifics: ground bearing pressure and slope limits, the swept path of the rear counterweight when turning, overhead powerline clearance, and segregation of the container stack rows from the travel lane.
Site planning is taught as a generic induction topic, and candidates do not connect the machine's rear-end swing and high point to layout design.
What to do instead
For any site-plan question, answer in four layers: ground (bearing capacity, slope, drainage, surface condition), space (swept path, stack rows, turning circles, exclusion zones), services (powerlines, pipelines, lighting), and people (pedestrian routes, crossing points, signage). Draw the rear-swing arc on a sketch to prove the point.
The candidate describes picking up a container as 'approach, lift and go' without confirming the four twistlocks are fully engaged and the twistlock indicator lights show locked before lifting, and without a test lift to confirm the load is secure.
Experienced operators do this automatically, so candidates skip the verbalised steps under exam pressure and forget that the assessor is marking the sequence.
What to do instead
Rehearse a fixed pick-up script: position square and centred → lower spreader → engage twistlocks → confirm all four indicators locked → test lift 100–200 mm and check for movement → raise to travel height → confirm travel path clear. Say each step aloud in practice.
On communication questions the candidate says 'use hand signals' without specifying who is authorised to signal, the emergency stop signal, the meaning of a signal that is not understood, and the rule that only one designated spotter directs the operator at a time.
Signals are learned as a picture chart rather than as a protocol with authority, and candidates do not know the 'stop on unclear signal' rule.
What to do instead
Learn the standard signals plus the protocol: one signaler at a time, signaler in clear view of the operator, any person may give the emergency stop signal, and an unclear or conflicting signal means stop immediately and clarify. Practise explaining the protocol in two sentences.
In an emergency scenario the candidate's first action is to try to fix the problem (e.g. lower a jammed load, fight a fire) rather than to make the situation safe - stop the machine, lower the load if possible, isolate, raise the alarm, and evacuate to the assembly point.
Candidates answer as operators rather than as duty holders, and they have not rehearsed the priority order of life safety over equipment.
What to do instead
Memorise the emergency priority order: people first (evacuate, account for personnel), then alarm and emergency services, then isolate energy, then contain (spill/fire) only if trained and safe, then preserve the scene for investigation. Apply it to fire, hydraulic burst, tip-over, dropped load and fuel spill scenarios.
At shutdown the candidate lowers the spreader and stops the engine but leaves the machine in gear or without the park brake, leaves the boom raised, or parks on a slope without chocking - and does not complete the post-operational log or refuel safely.
Shutdown is treated as 'switch off', and the securing sequence is not practised as a checklist.
What to do instead
Use a shutdown checklist in order: park on firm level ground → apply park brake → lower boom and spreader to rest → neutral → engine off → isolate and remove key → chock if on any slope → complete log and report defects → refuel only with engine off, no ignition sources, and spill kit available.
Environmental and fuel-handling answers are generic ('be environmentally friendly') and miss the reach stacker specifics: hydraulic hose and cylinder leak inspection, spill containment and reporting, correct disposal of contaminated absorbent, and the fire risk of refuelling near hot surfaces or with the engine running.
Environmental content is often delivered as an induction add-on rather than as part of the machine's daily routine.
What to do instead
Link each environmental control to a machine component: hoses and fittings (leak checks), fuel system (refuel procedure), spill kit location and use, waste segregation, and dust/noise controls near container yards. Practise a 60-second answer covering prevention, response and reporting for a hydraulic burst.
