Rigger Interview Questions
& Model Answers, 2026

As the angle between the sling leg and the horizontal decreases, the tension in each leg increases sharply for the same load — a shallow angle can put far more tension in a leg than the weight being lifted, and it also introduces large compressive forces into the load itself. The practical rule is to keep angles as steep as the headroom allows, calculate the leg tension rather than eyeballing it, and never assume that dividing the load by the number of legs gives the leg tension.

A vertical hitch uses the sling's rated capacity, a choker reduces it substantially because the sling body is bent and the load is gripped rather than supported, and a basket can approach double the vertical rating but only when the legs are truly vertical and the bend radius over the load is adequate. Every one of these figures comes from the sling's own tag, not from memory. Say that a damaged or missing tag means the sling is out of service.

Get the weight and centre of gravity from the drawing, the shipping documentation or the manufacturer where possible; where it is unknown, reason from the load's mass distribution, test-lift a few inches and observe the tilt, and reposition until it hangs level. Rig so the hook is directly above the centre of gravity and above the load's tipping point, and use adjustable legs or a spreader when the geometry demands it. A load that tilts on the test lift is telling you the rigging is wrong, not that you should lift faster.

Wire rope for broken wires, birdcaging, kinks, crushing, corrosion and heat damage; synthetic slings for cuts, abrasion, chemical damage, melting, exposed core yarns and an illegible tag; chain for stretch, gouges, nicks and bent links; shackles for pin fit, deformation, wear at the crown and any modification or substituted pin; hooks for throat opening, twist, cracks and a functioning latch. Any of those is removal from service, not a judgement call, and the item should be destroyed or tagged so it cannot return.

Tag lines of adequate length so handlers stay clear of the load and out of the pinch points, positioned to control rotation without pulling the load off vertical, no hands on the load once it is moving, and no riding a load ever. Keep everyone out from under and out of the swing path, and plan for wind on a large sail area. Say that pulling a load sideways with a tag line to reposition it is side loading the crane and is not acceptable.

Typically a lift near the crane's capacity, a multi-crane lift, a lift over occupied or live areas, a lift of a high-value or unique item, or a personnel platform lift, depending on the site's definition. When a lift is critical it needs a written and approved plan with load weights, rigging details, crane configuration and radii, ground bearing, roles including the lift director, and a pre-lift briefing. Say that you would not proceed on a critical lift without that documentation.

Real examples: a sling with a missing or illegible tag, a shackle with a bolt substituted for the pin, a homemade lifting lug, chain with visible stretch, or a load the crew wanted lifted by an unrated attachment point. Describe how you refused without escalating it into a confrontation, and what you supplied instead. Riggers are the last check before a load goes up and interviewers want people who reject without hesitation.

A test lift that tilted, a load heavier than stated, a load that started to spin, or rigging that shifted. Describe setting it back down rather than continuing, re-rigging, and re-briefing. Getting a load down safely and starting again is the correct outcome, and a story that ends with the crew wrestling a swinging load into place is the wrong story to tell.

Describe the pre-lift conversation: confirming the weight and rigging, agreeing the signals and who signals, walking the path, agreeing the stop protocol, and confirming radio channels. Say how you would raise a concern about the operator's setup respectfully. New pairings are exactly where miscommunication incidents happen.

Describe graduated responsibility: hardware inspection and staging before rigging anything, always with a qualified rigger checking, teaching the sling angle arithmetic properly rather than as a rule of thumb, and never letting them set rigging for a lift unsupervised until they can explain their reasoning. Add a correction you made and how you made it without embarrassing them.

Anchor on the published series: the BLS OEWS May 2025 national median for riggers is $62,640 a year ($30.12/hr), with the top 10% above $97,850. Position yourself by rigging certification level, whether you also hold signalperson qualification, and the sector — industrial, marine, entertainment and heavy haul price differently. Say whether you are quoting straight time, since outage and shutdown overtime shifts the annual figure substantially.

A great deal. Ask about the per-diem rate and whether it runs on weathered-out days, whether travel days at each end are paid, the guaranteed hours during an outage, and the overtime threshold and multiplier. Rigging work concentrates into shutdowns and specialist projects, so guaranteed hours and per diem are often worth more than a difference in the base rate.

Employer-funded rigger and signalperson certification and renewals, training toward the higher rigger level, employer-supplied and inspected rigging gear rather than personal purchases, PPE and boot allowance, and clarity about whether you are also expected to act as signaller or lift director, since those are separate qualified roles that should be recognised in the rate.
