NCCCO TELESCOPIC BOOM CRANE – SWING CAB
(TLL) EXAM (ACTUAL EXAM) WITH CORRECT
QUESTIONS
1. Outrigger Setup on Uneven Ground
Question: A crane is operating with a long
boom, on outriggers, on uneven ground.
Under these conditions, what is the most
important action?
• A) Extend outriggers to maximum reach
• B) Block under the float or pad to achieve
a 90degree angle between the cylinder
rod and the float
• C) Lower the boom to reduce leverage
• D) Use only three outriggers for stability
Answer: B – Blocking must create a 90-
degree angle between the cylinder rod and
the float/pad to ensure proper load
distribution and prevent sideloading on the
hydraulic cylinder .
2. Outrigger Float Requirements
,Question: According to OSHA 1926 Subpart
CC, when must floats/pads be fastened to the
outrigger/stabilizers?
• A) Only during travel
• B) When they are in use
• C) Only when operating on soft ground
• D) At all times, even when stowed
Answer: B – OSHA requires that floats/pads
be fastened to outriggers when they are in
use to prevent accidental displacement during
lifting operations .
3. Outrigger Beam Extension
Question: When is it permissible for
outrigger beams to be less than fully
extended?
• A) When a structure blocks full extension
• B) When lifting over the retracted
outrigger beam
• C) Only when the manufacturer's
procedures permit
• D) When operating on firm, level ground
, –
Answer: C Outrigger beams may only be
less than fully extended when the
manufacturer's procedures specifically permit
this configuration .
4. Leveling Procedure
Question: To properly level a crane, you set
a carpenter's level on the turntable or upper
works, level the crane to within 1%, then
swing the crane:
• A) 90 degrees and recheck level
• B) Over the front
• C) 180 degrees
• D) Over the rear and recheck
Answer: A – After initial leveling, swing the
crane 90 degrees and recheck level to ensure
the crane is level in all quadrants of rotation .
5. Outrigger Visual Contact
, Question: During crane setup when an
operator extends the crane's outriggers, the
operator should:
• A) Check tire pressure first
• B) Make visual contact with the outriggers
or post a signal person
• C) Sound the horn continuously
• D) Place all blocking on the ground before
extending
Answer: B – The operator must maintain
visual contact with outriggers or post a signal
person to ensure safe extension and prevent
crushing hazards .
DOMAIN 2: OPERATIONS (Approximately
23% of test)
6. Jib Offset Effect
Question: A crane's jib is offset 15 degrees
versus its original 0 degree offset, and the
boom angle remains unchanged. The load
radius will:
• A) Remain the same
