    When transporting a pick and carry “on rubber” the outriggers must be fully ____________?

    • A. 

      Removed

    • B. 

      Extended and stabilizers retracted

    • C. 

      Extended and stabilizers Extended

    • D. 

      Retracted and stabilizers Extended

    Correct Answer
    B. Extended and stabilizers retracted
    Explanation
    When transporting a pick and carry "on rubber," it is necessary to have the outriggers fully extended and the stabilizers retracted. This is because the outriggers provide stability and support to the vehicle while it is in operation, especially when lifting heavy loads. By extending the outriggers, the vehicle's weight is distributed evenly, reducing the risk of tipping over. On the other hand, retracting the stabilizers is important to avoid any damage or interference with the ground or other objects while the vehicle is being transported.
