NWSA TTT-1 EXAM VERIFIED QUESTIONS AND
CORRECT ANSWERS LATEST UPDATE
What is the minimum force that a positioning system anchorage must be able to withstand? - ANS-2
times the MAF(Maximum anticipated force) or 3,000 lbs
If a synthetic rope has a breaking strength of 6,600 lbs and a bowline knot is tied to make a lifting eye
what is the maximum gross load that can be lifted? - ANS-660 lbs. Synthetic rope has a safety factor of
10:1. That includes the weakening factor of the knot
Exposure to ionizing radiation dopes what to the human body? - ANS-IR can change cells and molecules
in biological organisms
When is a trained signal person necessary - ANS-When a crane can physically enter a powerline
restricted area.
What three ways can a capstan hoist be powered - ANS-Electric Gas and Hydraulic
When using tape and butyl to weatherproof a ground kit what is a critical step in the process? - ANS-
Always cut the tape with sciccors
According to regulations, what is the maximum arresting force allowed to the human body? - ANS-
Maximum arresting force allowed on the body is 1800 lbs. But our y-landyards reduce the force to half
that
What is the minimum number of ground kits installed in a single run - ANS-3. (1 at the top above the
hoisting grip. 1 at the base of the tower on the vertical run, 1 at the cabinet)
how often must a fire extinguisher be inspected by a qualified person? - ANS-Annually
What is a crown block? - ANS-Upper sheave assembly attached to the tower. Sheave assembly = pulley
or block
