1. What is the primary purpose of a load test on an overhead crane?
A. To check paint adhesion
B. To measure wheel alignment
C. To verify safe lifting capacity
D. To assess crane operator skills
Load tests ensure that the crane can safely lift its rated load without
failure, as required by OSHA and ANSI standards.
2. How often should a periodic inspection be performed on an overhead
crane used in normal service?
A. Weekly
B. Annually
C. Monthly
D. Every 5 years
Periodic inspections for normal service cranes are typically conducted
annually to assess structural integrity and operational safety.
,3. Which component of an overhead crane translates vertical lifting
motion into horizontal movement?
A. Wire rope
B. Trolley
C. Hoist drum
D. Load block
The trolley carries the hoist and moves horizontally along the bridge beam.
4. What is the acceptable minimum wire rope safety factor for a hoist with
a running sheave?
A. 3:1
B. 4:1
C. 5:1
D. 6:1
Per ASME B30.2, a minimum safety factor of 5:1 is required for running
wire ropes.
5. What type of inspection is required after a crane is modified or
repaired?
A. Frequent inspection
B. Initial inspection
C. Periodic inspection
D. Pre-shift inspection
An initial inspection must be conducted before returning the crane to
service after a modification or repair to verify safe operation.
, 6. What causes load swing in an overhead crane?
A. Loose trolley bolts
B. Sudden starts or stops
C. Hoist brake wear
D. Low oil levels
Sudden movements can create inertia, leading to load swing and potential
hazards.
7. What does the bridge in an overhead crane refer to?
A. The control system
B. The main horizontal beam
C. The lifting hook
D. The counterweight
The bridge is the main horizontal structure that spans the width of the
work area and supports the trolley.
8. What is the function of the hoist limit switch?
A. Controls crane speed
B. Stops the crane bridge
C. Prevents over-travel of the hook
D. Regulates oil pressure
The hoist limit switch stops lifting motion at the upper and lower limits to
prevent damage or overtravel.
9. What is the correct action if a crane has a cracked weld on the bridge
girder?
A. Operate under 50% capacity
B. Paint over the crack
