Introduction
This comprehensive examination is designed to rigorously assess the knowledge and practical skills required for
candidates pursuing the Missouri Hoisting Engineer Licensing Exam. The test evaluates a candidate's
understanding of state-specific regulations, fundamental hoisting and rigging principles, and the application of
safety protocols in real-world operating scenarios. It emphasizes critical decision-making, from interpreting load
charts to performing pre-operation inspections and responding to emergencies. The format includes multiple-
choice questions that challenge the applicant to apply technical knowledge to practical situations, ensuring they
are prepared to operate hoisting equipment safely and responsibly in accordance with Missouri law.
SECTION ONE: QUESTIONS 1 – 100
,1. Under Missouri law, when is a qualified hoisting engineer required to be on duty in noncoal mines?
A. Only during the day shift
B. While men are underground at noncoal mines where they are transported by hoists
C. Only when the mine employs more than 25 people
D. During the transportation of explosives only
🟢B
🔴 Explanation: The correct answer is B. According to Missouri Statute 293.590.1, a qualified hoisting
engineer must be on duty continuously when men are underground at noncoal mines where they are
transported by hoists .
2. The first step before operating any hoisting equipment is to:
A. Start the engine and warm it up
B. Conduct a pre-operation inspection
C. Review the load chart
D. Review the day's schedule
🟢B
🔴 Explanation: The correct answer is B. A pre-operation inspection is the first and most critical step to
ensure the equipment is safe to use. This is a standard and fundamental safety practice for all hoisting
operations .
3. What does OSHA stand for?
A. Occupational Safety and Hazard Administration
B. Occupational Safety and Health Administration
C. Official Safety and Hoisting Agency
D. Operational Safety Handling Authority
,🟢B
🔴 Explanation: The correct answer is B. OSHA sets and enforces workplace safety standards in the U.S.,
including regulations for cranes and hoisting equipment .
4. According to Missouri law, how often must hoisting equipment be inspected?
A. Weekly
B. Before each use
C. Monthly
D. Daily
🟢D
🔴 Explanation: The correct answer is D. Missouri Statute 293.590.3 requires that hoisting equipment be
inspected daily by a trained inspector and a record of the inspection must be kept .
5. What is the primary purpose of a load chart?
A. To estimate fuel consumption
B. To indicate safe lifting capacity under various conditions
C. To track maintenance schedules
D. To determine the weight of the load
🟢B
🔴 Explanation: The correct answer is B. A load chart provides critical information about the maximum safe
lifting capacity for a crane based on factors like boom length, angle, and radius. It must be reviewed before
any lifting operation .
6. The factor that most affects crane stability is:
A. The color of the crane
, B. Wind speed and load weight
C. The operator's height
D. The type of fuel used
🟢B
🔴 Explanation: The correct answer is B. Crane stability is a function of the load's weight and the
environmental conditions, such as wind speed. Exceeding load limits can cause tipping or structural failure .
7. What is the main hazard of overloading a crane?
A. Faster operation
B. Structural failure or tipping
C. Better efficiency
D. Reduced fuel use
🟢B
🔴 Explanation: The correct answer is B. Overloading a crane can cause it to collapse or tip over, leading to
catastrophic equipment failure, injuries, and fatalities .
8. What is the danger of side loading a crane?
A. Improved control
B. Structural stress and failure
C. Reduced noise
D. Faster lifting
🟢B
🔴 Explanation: The correct answer is B. Side loading puts stress on the crane's boom and other structural
components, which can cause them to fail. Side loading should always be avoided .
