SECTION 1: Crane Types & Components (Category 3 Classification) (6 questions)
Q1: A Category 3 crane as defined by ASME B30 standards is characterized by which
operational feature?
A. Operator positioned in an enclosed cab with full visibility controls
B. Operator on the floor using pendant pushbutton stations or remote radio/infrared controls
C. Operator using voice commands only without physical control devices
D. Fully automated operation without human operator intervention
Correct Answer: B
Rationale: ASME B30.2 (Overhead and Gantry Cranes) and B30.17 (Overhead and Gantry
Cranes, Top Running Bridge, Single Girder, Underhung Hoist) define Category 3 cranes as non-
cab operated—controlled by operators on the floor using pendant pushbutton stations or remote
radio/infrared control systems. Cab-operated cranes (A) are Category 1 or 2. Voice-only control
(C) is not a standard Category 3 classification. Fully automated systems (D) fall under different
ASME categories for automatic cranes. [CORRECT]
Q2: Which component on a Category 3 overhead crane is responsible for traversing the bridge
along the runway beams?
A. The trolley
B. The hoist
C. The end trucks
D. The pendant control station
Correct Answer: C
Rationale: End trucks (also called end carriages) house the wheels and drive motors that propel
the entire bridge along the runway beams. The trolley (A) travels across the bridge perpendicular
to the runway motion. The hoist (B) raises and lowers the load vertically. The pendant control
station (D) is the operator interface, not a motion component. ASME B30.2 defines end trucks as
critical bridge propulsion components requiring regular inspection. [CORRECT]

Q3: [Diagram Identification] In the diagram of a Category 3 bridge crane shown, the component
labeled "X" that connects the hoist to the trolley and allows vertical lifting motion is the:
A. Bridge girder
B. Runway beam
C. Load chain or wire rope hoist assembly
D. End truck drive wheel
Correct Answer: C
Rationale: The hoist assembly—whether chain or wire rope type—is the lifting mechanism
suspended from the trolley that provides vertical motion. ASME B30.16 (Overhead Hoists) and
B30.2 specify that hoist assemblies include the drum or sprocket, rope/chain, sheaves, hook
block, and upper/lower limit switches. The bridge girder (A) provides horizontal span structure.
Runway beams (B) support the bridge. End truck wheels (D) provide bridge travel along
runways. [CORRECT]
Q4: Which ASME B30 standard specifically addresses the safety requirements for underhung
hoists and cranes typically operated by pendant or remote controls in Category 3 applications?
A. ASME B30.5 (Mobile and Locomotive Cranes)
B. ASME B30.11 (Monorails and Underhung Cranes)
C. ASME B30.20 (Below-the-Hook Lifting Devices)
D. ASME B30.26 (Rigging Hardware)
Correct Answer: B
Rationale: ASME B30.11 specifically covers monorails and underhung cranes—systems where
the hoist/trolley assembly travels on the bottom flange of a runway beam, commonly operated
via pendant or remote controls in Category 3 configurations. B30.5 (A) addresses mobile cranes.
B30.20 (C) covers lifting attachments below the hook. B30.26 (D) addresses rigging hardware
(shackles, eyebolts, etc.) rather than crane systems. [CORRECT]
Q5: Which safety device on a Category 3 crane is designed to prevent the hook block from being
raised into the hoist drum or sheave assembly, potentially causing two-blocking or rope damage?
A. Load moment indicator
B. Upper limit switch
C. Anti-two-block warning device
D. Load weighing device
Correct Answer: B
Rationale: The upper limit switch (also called the hoist upper limit) is a required safety device
, 3
per ASME B30.2 and OSHA 1926.1416 that stops hoist motion when the hook block reaches a
predetermined maximum height, preventing contact with the drum/sheave assembly. Load
moment indicators (A) are for mobile cranes calculating capacity vs. radius. Anti-two-block
devices (C) are typically on mobile/telescopic cranes, though similar concepts apply. Load
weighing devices (D) monitor capacity but don't limit travel. [CORRECT]
Q6: A Category 3 wall-mounted jib crane differs from a bridge crane in that:
A. It has no hoist mechanism and relies on manual lifting only
B. It is supported by a vertical column or wall bracket and rotates about a fixed point rather than
traveling on runways
C. It requires a certified crane cab and seated operator at all times
D. It cannot use electric hoists and must be chain-operated manually
Correct Answer: B
Rationale: Wall-mounted or column-mounted jib cranes (ASME B30.11, B30.30) feature a
boom arm that rotates horizontally about a fixed pivot point, providing coverage within a circular
arc rather than rectangular bridge crane coverage. They commonly use electric chain hoists with
pendant or remote controls (Category 3 operation). They absolutely have hoist mechanisms (A
incorrect), do not require cabs (C incorrect), and commonly use electric hoists (D incorrect).
[CORRECT]
SECTION 2: Pre-Operational Inspections (8 questions)
Q7: According to OSHA 1926.1412 and ASME B30.2, which inspection item is classified as a
"frequent inspection" (required daily or before each shift) for Category 3 overhead cranes?
A. Magnetic particle testing of hook forgings
B. Operational testing of all limit switches and emergency stops
C. Load testing at 125% of rated capacity
D. Disassembly and inspection of gearboxes
Correct Answer: B
Rationale: Frequent inspections (OSHA 1926.1412(f), ASME B30.2-2.1.1) include operational
testing of safety devices—upper/lower limit switches, emergency stop buttons, and warning
devices—before each shift or daily. Magnetic particle testing (A) is periodic inspection. Load
testing (C) is required only after installation, repair, or modification. Gearbox disassembly (D) is
major maintenance, not frequent inspection. [CORRECT]
