B) Radius
C) Lift Zone
D) Quadrant
,E) Circumference. Answer: B) Radius
◉ What is two-blocking, and why is two-blocking dangerous?
A) Two-blocking occurs when the hook contacts another block or
hook on the crane. It is dangerous because the hook could damage
the crane, causing loss of load control.
B) Two-blocking occurs when the block or hook contacts the ground.
It is dangerous because the wire rope may come off of the drum and
drop the block.
C) Two-blocking occurs when the hook block comes in contact with
the upper sheave block during hoisting of the hook. It is dangerous
because it could result in damage to the crane, parting of the hoist
lines, and dropping the load.. Answer: C) Two-blocking occurs when
the hook block comes in contact with the upper sheave block during
hoisting of the hook. It is dangerous because it could result in
damage to the crane, parting of the hoist lines, and dropping the
