UK CPCS Telehandler Theory Exam common mistakes
UK CPCS Telehandler Theory Exam · Understand the traps and how to avoid them.
Treating the rated capacity on the load chart as a fixed number for the machine rather than reading the capacity for the actual boom length, boom angle/radius and attachment fitted at the point of lift.
Candidates memorise one headline capacity figure from training or a familiar machine and default to it, without practising reading across a chart grid for the specific configuration in front of them.
What to do instead
Practise reading charts by locating the intersection of radius (or boom angle) and boom length for the fitted attachment, then applying the de-rating for the attachment and any load-handling device before stating the safe working load.
Confusing gross vehicle weight, unladen weight and rated capacity, and therefore mis-stating whether a load or a vehicle can cross a ramp, bridge or floor slab.
The terms sound similar and candidates learn them as vocabulary rather than as distinct physical quantities applied to a scenario.
What to do instead
Learn each term with a worked example: unladen weight = machine alone; gross weight = machine plus load plus attachment; rated capacity = maximum permitted load for the configuration. Apply all three when assessing ground and structures.
Setting the load chart aside when a load is close to the machine, assuming capacity rises indefinitely as radius reduces.
The pattern 'closer equals safer' is intuitive and true up to a point, but candidates miss that charts are limited by boom strength, attachment rating and structural limits, not just tipping.
What to do instead
Learn that capacity is the lower of the structural/boom limit and the stability limit, and that near-radius lifts are often governed by the attachment or boom, not by tipping. Always read the chart rather than extrapolating.
Answering overhead-line questions with a single clearance figure and no consideration of goalposts, exclusion zones, barriers or the need to consult the line owner.
Candidates latch onto one memorable distance and treat the question as a recall test rather than a safe-system-of-work question.
What to do instead
Structure the answer as a system: identify the voltage and owner, establish the specified clearance plus a margin, mark the zone with goalposts and barriers, brief and sign off, and use a banksman where visibility is restricted.
Describing pre-use checks as a walk-round glance, omitting fluid levels, tyre condition and pressure, hydraulic hose and ram condition, attachment locking pins, seat belt, alarms, lights and the function test of controls.
Candidates recall the idea of a check but not the checklist, and under exam pressure they generalise instead of listing items.
What to do instead
Learn a fixed sequence (around the machine, under the machine, in the cab, function test) and rehearse naming specific components in each stage, including defect recording and the stop-work decision.
Treating a defect as something to note at the end of the shift rather than reporting it immediately and taking the machine out of service where it affects safety.
Site culture and habit lead candidates to prioritise finishing the task, and they under-estimate how the exam tests the reporting chain and the authority to stop.
What to do instead
Learn the rule that safety-critical defects mean stop, isolate, tag and report to the supervisor immediately, with the defect entered in the record book; distinguish this from minor defects logged for scheduled maintenance.
Travelling with the boom raised or the load high, and failing to keep the load low and the machine level when moving across site.
Candidates separate 'travelling' from 'lifting' in their minds and do not apply stability principles to travel.
What to do instead
Learn the travel rule: boom retracted and lowered, load close to the ground, machine level, correct gear and speed, and a banksman where visibility or ground conditions require it.
Answering incline questions by naming a gradient figure only, without describing the technique of travelling up and down, keeping the load uphill, and avoiding traversing or turning on slopes.
Candidates reduce slope questions to a number and miss that the examiner is testing the manoeuvre and the stability reasoning.
What to do instead
Learn the full technique: assess the slope and ground, travel straight up or down with the load on the uphill side, keep the boom low, avoid cross-slopes and turns, and stop if conditions are outside the machine's limits.
Describing lifting and placing as a single action, omitting the banksman/signaller, exclusion of personnel under the load, the trial lift, and the controlled lowering and placement.
Candidates focus on the machine controls and forget the surrounding safe system of work and communication.
What to do instead
Learn a staged sequence: plan and brief, position and level, check the load and rigging, trial lift to confirm stability and brakes, move under signal, lower and place, then release and withdraw with the boom clear.
Giving vague emergency answers such as 'call the emergency services' without describing isolation, lowering the load, machine shutdown, first aid, preserving the scene and reporting under RIDDOR-type requirements.
Candidates treat emergency procedures as common sense and do not learn the site-specific sequence or the reporting duties.
What to do instead
Learn a fixed emergency sequence: make safe and isolate, lower and secure the load, shut down and evacuate if needed, raise the alarm and give first aid, then report and record the incident through the site procedure.
