Illinois Crane Operator Certification Examination Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary purpose of a load chart on a crane?
• To determine the fuel consumption of the crane
• To calculate the crane’s lifting capacity at different configurations
• To record operator work hours
• To provide maintenance schedules
• To calculate the crane’s lifting capacity at different configurations

Rationale: A load chart specifies the maximum safe lifting capacity for

various boom lengths, angles, and configurations to prevent tipping or structural failure. 1 / 4

• Which OSHA standard regulates crane operation in construction?

A. OSHA 1910

B. OSHA 1926

C. OSHA 1904

D. OSHA 1915

B. OSHA 1926

Rationale: OSHA 1926 Subpart CC covers the safety requirements for

construction cranes, including operation, inspections, and operator qualifications.

• What is the primary purpose of a crane’s outriggers?
• To increase speed
• To stabilize the crane during lifts
• To assist with steering
• To measure load weight
• To stabilize the crane during lifts

Rationale: Outriggers extend the base of the crane to prevent tipping when

lifting loads, particularly at long reaches or heavy weights.

4. Before starting a lift, the crane operator must:

• Check weather conditions and perform pre-lift inspection
• Only check the load weight
• Start lifting immediately to save time
• Inform nearby pedestrians 2 / 4

• Check weather conditions and perform pre-lift inspection

Rationale: Pre-lift inspections and weather checks are critical for safe crane

operation to prevent accidents caused by equipment failure or adverse conditions.

• What is the most critical factor when determining crane stability?
• Operator experience
• Load weight, boom length, and ground conditions
• Time of day
• Type of hook
• Load weight, boom length, and ground conditions

Rationale: Crane stability depends on the combination of load weight,

boom extension, and the ground’s ability to support the crane without tipping.

• How often should a crane undergo a thorough inspection according to

OSHA?

• Monthly
• Annually
• Before each shift and periodically as required
• Every five years
• Before each shift and periodically as required

Rationale: OSHA requires pre-shift inspections for operational safety and

periodic inspections depending on the crane type and use. 3 / 4

• Which signal is commonly used to stop a crane immediately?
• One short blast
• Two long blasts
• One continuous blast
• Three short blasts
• One continuous blast

Rationale: Standard hand and whistle signals designate one continuous

blast as an emergency stop to alert all personnel immediately.

• What is the effect of operating a crane on soft or uneven ground

without proper support?

• No effect
• Can cause the crane to tip over
• Increases lifting capacity
• Improves maneuverability
• Can cause the crane to tip over

Rationale: Uneven or soft ground may not support the crane’s weight,

increasing the risk of tipping, which is why pads or mats are used under outriggers.

• Which type of crane is commonly used in construction for high-rise

buildings?

• Gantry crane
• Tower crane
