TTT-1 Hoisting & rigging Practice Test
10 questions · 20% of the real TTT-1 exam · instant scoring · explanations cite the standard
Hoisting and rigging is 20% of TTT-1. At this level the exam wants the ground-crew fundamentals: hitches and their capacities, shackle loading, drop zones, signals, capstan safety, tag lines and when rigging is retired under ASME B30. Ten questions, each explained with its source.

A sling's rated capacity is lowest in which hitch?
Show answer and explanation
Correct answer: C. Choker hitches reduce capacity (typically to about 75–80% of vertical) because of the bend at the choke. Basket is highest when legs are vertical, at about twice vertical.
The breaking strength of rigging hardware is typically how many times its WLL?
Show answer and explanation
Correct answer: C. A 5:1 design factor is standard for shackles, hooks and most hardware. The margin is for shock, wear and uncertainty — not available for use.
A shackle should be loaded:
Show answer and explanation
Correct answer: A. In-line loading on the bow, pin seated. Side loading reduces capacity sharply; a rotating rope on a screw pin can back it out.
Before hoisting, the ground crew must establish:
Show answer and explanation
Correct answer: A. The drop zone is the area under the load path where a dropped object lands. It is marked, communicated at the JHA, and nobody enters it while a load is in the air.
Hand signals and radio commands between the climber and hoist operator should be:
Show answer and explanation
Correct answer: B. One signal person, standard signals, agreed before the lift. Anyone can call STOP, but only the designated signaler directs the load.
A capstan hoist works by:
Show answer and explanation
Correct answer: B. The operator's grip on the tail controls the lift. Letting go releases the load — which is why the tail is never wrapped around a hand or body.
Wire rope with a kink should be:
Show answer and explanation
Correct answer: C. A kink permanently displaces the strands. B30 lists kinking as an immediate removal criterion.
Before hoisting an antenna, its weight is determined from:
Show answer and explanation
Correct answer: B. Known weight plus the weight of all rigging gives the gross load, which is compared against the hoist, rope and rigging ratings — and the structure's temporary load limits.
Synthetic slings must be protected from:
Show answer and explanation
Correct answer: B. Edges cut synthetic webbing under load. Edge protection is required wherever the sling contacts a corner, and UV exposure is a separate retirement consideration.
During a lift, a tag line should be:
Show answer and explanation
Correct answer: B. A load that swings or snags will take a wrapped hand with it. The tag line is held, not attached.

Frequently asked questions
How much of the NWSA TTT-1 exam is hoisting & rigging?
20%, per the Candidate Handbook REV 10/25 content outline. The full TTT-1 exam is 85 questions · 90 minutes.
Is the NWSA exam computer-based?
Yes. Since January 2024 every NWSA certification exam is delivered by Online Remote Proctoring (ORP) — you take it on your own computer with a live proctor. The practical exam component was discontinued at the same time.
What score do I need to pass the NWSA exam?
NWSA does not publish a passing score. Exams are criterion-referenced and the cut score is set by a panel of subject-matter experts; results are reported as pass/fail with a domain-by-domain breakdown. Any site quoting a specific percentage is guessing.
How much does the NWSA exam cost?
$274 for every NWSA certification — TTT-1, TTT-2, A&L, Foreman and ARC. Retakes are the same $274, with a 30-day wait between attempts. Fees are set by NWSA and can change; nws-a.org is the authority.
