    Which is part of the Basic Guidelines?

    • Never exceed the W.L.L.

    • Always use a tag line

    • Never get under the load

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The Basic Guidelines include never exceeding the W.L.L. (Working Load Limit), always using a tag line, and never getting under the load. These guidelines are important for ensuring safety and preventing accidents when working with heavy loads. By following these guidelines, workers can minimize the risk of overloading equipment, maintain control of the load, and avoid being in a dangerous position underneath the load. Therefore, the correct answer is "all of the above" as all three statements are part of the Basic Guidelines.

    Never side load a round pin shackle.

    • TRUE

    • FALSE

    Correct Answer
    A. TRUE
    Explanation
    Side loading a round pin shackle can cause it to fail under load. Round pin shackles are designed to be loaded in-line with the pin, not at an angle. When a round pin shackle is side loaded, it puts stress on the pin and can cause it to bend or break. This can lead to the shackle coming apart and potentially causing injury or damage. Therefore, it is important to never side load a round pin shackle to ensure safety and prevent accidents.

    When would you take a wire rope out of service? 

    • 3 broken wires in one strand of a lay

    • 6 broken wires in one entire lay

    • Kinking birdcaging or distortion of wire rope

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The given answer, "All of the above," is correct because any of the mentioned conditions can indicate a wire rope that needs to be taken out of service. If there are 3 broken wires in one strand of a lay, it indicates potential weakness and compromise of the rope's strength. Similarly, if there are 6 broken wires in one entire lay, it further highlights the deterioration of the rope. Kinking, birdcaging, or distortion of the wire rope can also lead to reduced strength and reliability. Therefore, any of these conditions warrant removing the wire rope from service to ensure safety.

    Sometimes we need to use__________to avoid damaging rigging and/or equipment.

    • The working load limit

    • Softeners

    • W.L.L

    • Common sense

    Correct Answer
    A. Softeners
    Explanation
    Softeners are sometimes needed to avoid damaging rigging and/or equipment. Softeners are materials or devices that are used to cushion or protect the rigging or equipment from excessive force or pressure. They can be used to distribute the load more evenly, reduce friction, absorb shock, or provide a buffer between the rigging and equipment. By using softeners, potential damage to the rigging or equipment can be minimized, ensuring their longevity and safe operation.

                      If you are picking a unit of 16ea. (12"x12"x10') long timbers which are made out of oak, How heavy is the load? - ProProfs

                      If you are picking a unit of 16ea. (12"x12"x10') long timbers which are made out of oak, How heavy is the load?

    • "Approx..5,000lb."

    • "Approx..10,000lb."

    • "Approx..15,000lb."

    • "Approx..20,000lb."

    Correct Answer
    A. "Approx..10,000lb."
    Explanation
    The correct answer is "Approx..10,000lb." because each timber weighs approximately 625lb (10,000lb divided by 16).

    When using a 2 part bridle it is better to have a higher sling angle for more lifting capacity.

    • TRUE

    • FALSE

    Correct Answer
    A. TRUE
    Explanation
    A higher sling angle refers to the angle at which the sling is attached to the load being lifted. When using a 2 part bridle, a higher sling angle means that the load is being lifted more vertically, which allows for greater lifting capacity. This is because a higher sling angle reduces the load on each individual sling leg, distributing the weight more evenly and increasing the overall lifting capacity. Therefore, having a higher sling angle is indeed better when using a 2 part bridle.

    Before using a spreader bar you must have the following items. (check all that apply)

    • A capacity stamped on the spreader bar

    • A design drawing showing correct configuration

    • A photo of the spreader bar in the district office

    • A pipe welded to the spreader bar with the design inside of it?

    Correct Answer(s)
    A. A capacity stamped on the spreader bar
    A. A design drawing showing correct configuration
    Explanation
    The correct answer is a capacity stamped on the spreader bar and a design drawing showing correct configuration. These items are necessary before using a spreader bar to ensure that it is safe and suitable for the intended lifting operation. The capacity stamped on the spreader bar indicates the maximum weight it can safely handle, while the design drawing shows the correct configuration to ensure proper usage. Both of these items are crucial for ensuring the safety and effectiveness of the spreader bar during lifting operations.

    When all legs of the sling will be equally spaced around the center of gravity, the sling sizes should be based on only four legs as the load can teeter from corner to corner thus loading only two slings.

    • TRUE

    • FALSE

    Correct Answer
    A. FALSE
    Explanation
    When all legs of the sling are equally spaced around the center of gravity, the load will be evenly distributed among all the legs. This means that each sling will bear an equal portion of the load, and there will be no teetering or uneven loading. Therefore, the statement that the sling sizes should be based on only four legs is incorrect. The correct answer is FALSE.

    If the rigging on your hook is 1/2 in. off-center. approx what percentage of the load can it carry?

    • 75%

    • 80%

    • 85%

    • 90%

    Correct Answer
    A. 80%
    Explanation
    If the rigging on the hook is 1/2 inch off-center, it means that the load is not evenly distributed. This imbalance can reduce the load-carrying capacity of the hook. The correct answer of 80% suggests that the hook can still carry 80% of its maximum load despite the off-center rigging. This means that the rigging imbalance has a moderate impact on the load-carrying capacity, reducing it by 20%.

    When using a 2 part bridle with a sling angle of 45degrees, what size rigging would be needed to lift a load of 31,000 pounds? - ProProfs

    When using a 2 part bridle with a sling angle of 45degrees, what size rigging would be needed to lift a load of 31,000 pounds?

    • 1 1/8

    • 1 1/4

    • 1 3/4

    • 2-Jan

    Correct Answer
    A. 1 1/4
    Explanation
    When using a 2 part bridle with a sling angle of 45 degrees, the size of the rigging needed to lift a load of 31,000 pounds is 1 1/4. The sling angle affects the capacity of the rigging, and a 45-degree angle reduces the capacity by approximately 30%. Therefore, the rigging size needs to be larger to compensate for the reduced capacity and ensure the safe lifting of the load. In this case, 1 1/4 is the appropriate size to handle the 31,000-pound load with a 45-degree sling angle.
