  1. Before beginning operations, which document must a crane operator review to confirm the crane's rated capacity for the planned lift?

    Answer: Operator's manual and load chart

    ASME B30.5 and OSHA 1926.1412 require operators to review the load chart and operator's manual before each shift to confirm rated capacities for all configurations.

  2. During a pre-operation inspection, you discover a hydraulic hose with a visible bulge and minor weeping. What is the correct action?

    Answer: Tag the crane out of service and notify the supervisor

    A bulging or weeping hydraulic hose is a deficiency that removes the crane from service under ASME B30.5 inspection criteria. Operations must not resume until the hose is replaced.

  3. Which of the following is checked during a frequent inspection of a mobile crane under ASME B30.5?

    Answer: All functional operating mechanisms for maladjustment

    ASME B30.5-5.2.2 defines frequent inspections (daily to monthly) as covering all functional operating mechanisms, air/hydraulic systems, hooks, and rope reeving.

  4. The anti-two-block device on a crane is designed to prevent:

    Answer: The load block from contacting the boom tip and damaging the wire rope

    An anti-two-block (A2B) device stops hoist motion before the upper load block contacts the boom tip sheave assembly, which would cause rope failure or structural damage.

  5. Under OSHA 1926 Subpart CC, how often must a qualified person conduct a shift inspection of a crane?

    Answer: Each shift the equipment is used

    OSHA 1926.1412(d) requires a qualified person to conduct a shift inspection before each shift the crane is used, checking for visible damage, deficiencies, and proper lubrication.

  6. A crane's load chart shows 'ON OUTRIGGERS — FULLY EXTENDED' for the rated capacities. If the operator sets up on rubber tires instead, what must happen?

    Answer: Use the on-rubber-tire column of the load chart, which shows reduced capacities

    Load charts have separate columns for different configurations (full outriggers, partial outriggers, on rubber). Using the outrigger chart values while on rubber tires would exceed the crane's true capacity in that configuration.
