2. Crane Range Diagram

Try these first

1. 1.

   What are outriggers used for in crane operations?

   Hint

   Think about how cranes stay upright.

2. 2.

   Why is it important to check the load moment indicators?

   Hint

   Remember, exceeding limits can cause accidents!

3. 3.

   What is the primary purpose of outriggers?

   • To lift heavier loads
   • To stabilize the crane
   • To extend the boom

   Hint

   Consider the crane's balance while lifting.

4. 4.

   True or False: Load moment indicators are used to monitor the crane's fuel level.

   • True
   • False

   Hint

   Think about their function in preventing overloading.

5. 5.

   A crane is set to lift a load to a height of 100 meters at a radius of 50 meters. Using the range diagram, what boom length will you need?

   Hint

   Draw a quick sketch to visualize the height and radius.

6. 6.

   A construction site requires lifting equipment to meet a specific requirement of 10,000 kg. Calculate the crane's possible net capacity if the rigging weighs 1,200 kg and determine if a boom length of 45 meters is sufficient.

   Hint

   Remember to check the load capacity charts for specific boom lengths!
