Read the first 6 Pre-Lift Planning & Load Chart Interpretation flashcards as text

  1. Which document defines the crane's maximum allowable wind speed for safe operation?

    Answer: The crane manufacturer's load chart and operator's manual

    The manufacturer's load chart and operator manual specify wind speed limitations that must not be exceeded during operation.

  2. When using a mobile crane on a slope, what is the general OSHA-aligned rule regarding level setup?

    Answer: The crane must be set up level per the manufacturer's specifications, typically within 1% grade

    Manufacturers typically require cranes to be set up level within 1% (about 0.6°) to maintain rated capacity and stability.

  3. What information must be confirmed about the load before referencing the load chart?

    Answer: Load weight, center of gravity, and attachment points

    Knowing the load's weight, center of gravity, and attachment points is essential to select proper rigging and correctly apply the load chart.

  4. A lift plan requires a crane to work near overhead power lines. What is the minimum clearance required under OSHA 1926.1408 for lines up to 50 kV?

    Answer: 10 feet

    OSHA 1926.1408 requires a minimum 10-foot clearance from power lines up to 50 kV unless the utility has de-energized and visibly grounded the line.

  5. During pre-lift planning for a tandem (two-crane) lift, what must be calculated for each crane?

    Answer: Each crane's share of the load, its percent of rated capacity, and its individual lift plan

    Each crane in a tandem lift must have its individual load share calculated, verified against its rated capacity, and documented in the plan.

  6. What is the role of a lift director on a critical or multi-crane lift under OSHA 1926.1431?

    Answer: To direct the operations, ensuring the lift plan is followed and all personnel are briefed

    OSHA 1926.1431 requires a qualified lift director to oversee critical and multi-crane lifts, coordinate personnel, and ensure the written plan is executed correctly.
