NWSA TT-1 EXAM Questions and
Answers
1. What is the minimum force that a positioning system anchorage
must be able to withstand?: 2 times the MAF(Maximum anticipated force) or 3,000
lbs
2. 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?: 660 lbs. Synthetic rope has a safety factor of 10:1. That
includes the weakening factor of the knot
3. Exposure to ionizing radiation dopes what to the human body?: IR
can change cells and molecules in biological organisms
4. When is a trained signal person necessary: When a crane can physically enter

Hydraulic
6. When using tape and butyl to weatherproof a ground kit what is
a critical step in the process?: Always cut the tape with sciccors
7. According to regulations, what is the maximum arresting force
allowed to the human body?: Maximum arresting force allowed on the body is 1800 lbs.
But our y-landyards reduce the force to half that
8. What is the minimum number of ground kits installed in a single
run: 3. (1 at the top above the hoisting grip. 1 at the base of the tower on the vertical run, 1 at
the cabinet)
9. how often must a fire extinguisher be inspected by a qualified
person?: Annu-ally
10. What is a crown block?: Upper sheave assembly attached to the tower. Sheave
assembly = pulley or block
