SECTION 1: Site and Equipment Setup
Ground Conditions, Setup Procedures, Load Charts, and Lift Planning (Q1-Q25)
Q1: A crane operator is preparing to set up a hydraulic truck crane on a construction site. The soil at the
designated setup area appears to be soft, saturated clay after recent rainfall. What is the FIRST action
the operator should take before positioning the crane?
A. Place additional timber mats under the outrigger pads to distribute the load
B. Consult the crane manufacturer's load chart and refuse to set up until a site assessment confirms
ground bearing capacity is adequate for the expected crane loading [CORRECT]
C. Extend the outriggers fully and begin lifting operations to test ground stability
D. Reduce the crane's rated capacity by 50% to compensate for poor soil conditions
Correct Answer: B
Rationale: Per OSHA 1926.1402 and ASME B30.5, the operator must assess ground conditions before setup. Soft saturated clay
has significantly reduced bearing capacity, and placing mats without knowing whether the ground can support the crane's load is
insufficient. The manufacturer's load chart specifies required ground bearing pressure; the operator must verify the site meets
these requirements before setup. Simply extending outriggers or reducing capacity arbitrarily are not acceptable substitutes for a
proper site assessment.
Q2: During a site assessment for a lattice boom crawler crane, the operator identifies an overhead power
line approximately 25 feet above the planned swing path. The power line is energized at 350 kV.
According to OSHA 1926.1408, what is the minimum approach distance the crane must maintain from
this power line?
A. 10 feet
B. 20 feet
C. 25 feet
D. 35 feet [CORRECT]
Correct Answer: D
Rationale: OSHA 1926.1408 Table A specifies minimum approach distances based on line voltage. For lines rated at 350 kV, the
minimum approach distance is 35 feet. Ten feet applies to lines up to 50 kV, 20 feet to lines from 50-200 kV, and 25 feet to lines
from 200-350 kV. Since this line is at the upper end of the 200-350 kV range, the full 35-foot distance applies. These distances are
mandatory and non-negotiable under OSHA Subpart CC.
Q3: An operator is setting up a rough terrain crane with outriggers on a sloped surface. The slope
measures approximately 1.5% grade across the setup area. Which of the following is the CORRECT
procedure for outrigger deployment on this surface?
A. Extend all four outriggers fully and level the crane using the built-in level indicator until the bubble is
centered [CORRECT]
B. Place cribbing under the downhill outriggers only to compensate for the slope
C. It is acceptable to set up on a 1.5% slope without any leveling adjustments since this is within most crane
manufacturers' tolerances
D. Position the crane perpendicular to the slope direction and extend only the two uphill outriggers
Correct Answer: A
Rationale: ASME B30.5 requires that cranes be leveled before operation. The standard practice is to extend all outriggers fully
and use appropriate cribbing or mats to achieve a level condition as indicated by the crane's level indicator. Placing cribbing under
only downhill outriggers is an unsafe practice that can create unstable loading conditions. While 1.5% is a modest slope, the crane
must still be leveled. Operating with only two outriggers extended is prohibited for lifting operations.
Q4: A crane operator is reviewing a load chart for a 100-ton hydraulic truck crane configured with a
100-foot main boom at a 40-degree boom angle. The chart shows a rated capacity of 45,000 pounds at a
