This assessment is designed to evaluate the operational knowledge, safety awareness, load-
handling capability, inspection procedures, signaling competency, and regulatory compliance
expected of professional mobile crane operators working within construction, industrial, and
infrastructure environments across Texas and the United States. The examination reflects
industry-recognized operational standards commonly applied to telescopic boom cranes,
lattice boom cranes, hydraulic systems, rigging procedures, and OSHA-regulated lifting
operations. Candidates are expected to demonstrate sound judgment, hazard recognition,
load chart interpretation, and practical decision-making skills required for safe crane
operation under varying site conditions and environmental challenges.
Core Competency Areas:
Crane Safety and OSHA Regulations
Load Charts and Capacity Calculations
Rigging Hardware and Sling Selection
Crane Setup and Ground Conditions
Operational Controls and Maneuvering
Hand Signals and Communication
Power Line Safety
Inspection and Preventive Maintenance
, Lift Planning and Site Hazard Assessment
Emergency Procedures and Operational Shutdown
Candidate Instructions: This examination contains approximately 120 multiple-choice
questions. Candidates are allotted 3.5 hours to complete the full assessment. Read each
question carefully before selecting the best answer. Only one answer is correct for each
question unless otherwise specified. Calculators approved by the testing administrator may
be used for load calculations. Candidates must comply with all examination security rules
and may not communicate with other candidates during testing. Marks should be made
clearly and legibly on the answer sheet provided by the examination administrator.

Q1. A mobile crane operator is preparing to lift a 14,000-pound HVAC unit onto the roof
of a commercial structure. The load chart indicates a maximum allowable capacity of
16,500 pounds at the planned radius and boom length. Wind gusts are increasing and the
operator notices minor side loading during test lifting. What is the MOST appropriate
action?
A. Proceed because the crane remains below charted capacity
B. Continue lifting slowly while relying on the outriggers for stability
, C. Stop operations and reassess lift conditions before proceeding
D. Increase boom angle to compensate for the side loading
Correct Answer: 🔴 C. Stop operations and reassess lift conditions before proceeding
Explanation: 🔹 The correct answer is C because side loading and increasing wind conditions
create significant instability hazards that are not fully accounted for in basic load chart
capacity values. Safe crane operations require reassessment whenever environmental or
operational conditions change unexpectedly. Option A is incorrect because operating below
chart capacity alone does not guarantee safe lifting. Option B is unsafe because outriggers
cannot compensate for hazardous side loading conditions. Option D is incorrect because
altering boom angle without recalculating the lift could worsen instability and structural
stress.
Q2. During crane setup, one outrigger begins sinking slightly into the ground after the
crane has been leveled. What should the operator do FIRST?
A. Continue operations if the load is under 50% capacity
B. Retract the boom immediately and stabilize the ground conditions
C. Add counterweight to offset the instability
D. Swing the crane away from the sinking outrigger
Correct Answer: 🔴 B. Retract the boom immediately and stabilize the ground conditions
Explanation: 🔹 The correct answer is B because unstable ground conditions are a major
