QUESTION 1
How many pounds are in a ton?
A) 1,000 pounds
B) 1,500 pounds
C) 2,000 pounds
D) 2,500 pounds
Correct Answer: C
Explanation: A standard ton, also known as a short ton, is equivalent to
2,000 pounds. This is a fundamental conversion that operators must
know for load weight calculations and capacity assessments. The long
ton (2,240 pounds) is used in some contexts, but the standard ton for
hoisting and construction in the United States is 2,000 pounds.
QUESTION 2
What type of equipment requires a hoisting license in Massachusetts?
,2|Page
A) Equipment that lifts higher than 5 feet or lifts more than 250 pounds
B) Equipment that lifts higher than 10 feet or lifts more than 500
pounds, or has a bucket capacity greater than 1/4 cubic yard
C) Equipment that lifts higher than 15 feet or lifts more than 750
pounds
D) Only cranes and derricks regardless of height or weight
Correct Answer: B
Explanation: Under Massachusetts regulations, a hoisting license is
required for any equipment that lifts higher than 10 feet, can lift more
than 500 pounds, or has a bucket capacity greater than 1/4 cubic yard.
These thresholds are specified in M.G.L. Chapter 146 and 520 CMR 6.00.
QUESTION 3
What is the minimum safe approach distance from power lines up to
125,000 volts when operating hoisting machinery?
A) 5 feet
B) 10 feet
C) 15 feet
D) 25 feet
Correct Answer: B
Explanation: For power lines up to 125,000 volts, operators must
maintain a minimum clearance of 10 feet. This distance increases to 15

feet for voltages between 125,000 and 250,000 volts, and 25 feet for
voltages over 250,000 volts. These clearance requirements are critical
for preventing electrocution and arc flash incidents.
QUESTION 4
How do you test the load brakes on hoisting equipment?
A) Lift the load 6 inches and hold for 30 seconds
B) Lift the load 1 foot and hold for 1 minute
C) Lift the load 2 feet and hold for 2 minutes
D) Apply the brakes while the load is on the ground
Correct Answer: B
Explanation: The proper procedure for testing load brakes is to lift the
load approximately 1 foot off the ground and hold it in that position for
1 minute. If the load does not hold or drifts downward, the brakes are
faulty and the equipment must be taken out of service for repairs. This
test ensures that the braking system can safely hold a suspended load.
QUESTION 5
If gauges do not register normal readings during operation, what should
the operator do?
A) Continue operating and monitor the gauges closely
B) Increase engine speed to compensate
C) Turn off the engine and notify the supervisor
, 4|Page
D) Add more hydraulic fluid immediately
Correct Answer: C
Explanation: Abnormal gauge readings indicate a potential mechanical
or hydraulic problem that could lead to equipment failure or safety
hazards. The operator should immediately shut down the engine to
prevent further damage and notify the supervisor so that the issue can
be properly diagnosed and repaired before resuming operations.
QUESTION 6
How should any load be carried with a loader?
A) As high as possible for visibility
B) As low as possible
C) At mid-height for stability
D) With the bucket fully extended forward
Correct Answer: B
Explanation: Loads should be carried as low as possible to maintain the
lowest center of gravity and maximize stability. A low carry position
reduces the risk of tip-over, improves visibility, and minimizes the
pendulum effect that can occur when the load is elevated. This practice
is fundamental to safe loader operation.
