3. Determining Boom Length and Maximum Load

Try these first

1. 1.

   What is the minimum distance a crane must maintain from high voltage lines according to OSHA?

   Hint

   Consider the hazard of electrocution.

2. 2.

   What role do outriggers play in crane stability?

   Hint

   Think about how cranes stand on different ground types.

3. 3.

   What should be the minimum distance of a crane from high voltage lines?

   • 1 meter
   • 3 meters
   • 5 meters

   Hint

   This is crucial for safety.

4. 4.

   True or False: Outriggers must always be used to stabilize a crane.

   • True
   • False

   Hint

   Think about different terrains.

5. 5.

   A crane is set to lift a load that is 15 meters away and must reach a height of 38 meters. If the rigging adds 5 meters, determine the boom length needed using a range diagram.

   Hint

   Use the diagram to visualize and compute the values.

6. 6.

   If a crane is rated for a maximum load of 20,000 kg, and the hook, block, and sling weight totals 1,500 kg, what is the maximum net load it can lift?

   Hint

   Always account for rigging in maximum load calculations.
