Try these first

  1. 1.

    What is the main purpose of outriggers in crane operations?

    Hint

    Think about what happens when a crane lifts without stability.

  2. 2.

    What does the term 'operating radius' refer to?

    Hint

    It involves the load's location relative to the crane center.

  3. 3.

    What is the primary function of outriggers?

    • They increase mobility
    • They stabilize the crane
    • They extend the boom
    Hint

    Think about balancing forces.

  4. 4.

    True or False: Operating radius affects the lifting capacity.

    • True
    • False
    Hint

    Consider what happens to the load when distances change.

  5. 5.

    If a truck-mounted crane with an operating radius of 15m does not use its outriggers, what would be the expected reduction in load capacity?

    Hint

    Refer to the guidelines and consequences of outrigger usage.

  6. 6.

    Given a scenario where a crane tips over despite having outriggers extended, analyze what factors could have led to this failure.

    Hint
