3.1. Example Problem Statement

Try these first

1. 1.

   What are outriggers used for in crane operation?

   Hint

   Consider their role in weight distribution.

2. 2.

   What distance should be maintained from high voltage lines?

   Hint

   Think about safety regulations.

3. 3.

   What is the first step in ensuring the safety of crane operations?

   Hint

   Think about the primary support system of the crane.

4. 4.

   Is it safe to operate a crane when wind speeds exceed 72 kilometers per hour?

   • True
   • False

   Hint

   What does safety protocol say about wind conditions?

5. 5.

   A crane must lift a 10-ton load to a height of 30 meters. Calculate the required boom length if the horizontal reach is 25 meters. Use a crane range diagram to show your work.

   Hint

   Use the x and y axes of the diagram correctly.

6. 6.

   Given the crane is lifting with a boom length of 60 meters, how should you adjust the lifting capacity if the wind speed rises to 80 kilometers per hour?

   Hint

   What operational adjustments are necessary according to safety protocols?
