3.4. Excluding Additional Weights

Try these first

1. 1.

   What is the minimum distance a crane should maintain from high voltage lines?

   Hint

   Think about the standard safety regulations regarding power lines.

2. 2.

   What are outriggers used for?

   Hint

   Consider what happens to a crane when it isn't stable.

3. 3.

   What is the safe distance from power lines when operating a crane?

   • 1 meter
   • 3 meters
   • 5 meters

   Hint

   Consider safety regulations for operating near electrical hazards.

4. 4.

   True or False: Outriggers should be deployed on unstable ground to ensure crane safety.

   • True
   • False

   Hint

   Think about the consequences of deploying outriggers incorrectly.

5. 5.

   A crane must lift a load weighing 10,000 kg to a height of 60 meters while having a horizontal reach of 30 meters. Determine if the crane can safely perform this lift. Use the range diagram data provided.

   Hint

   Refer to provided load charts and boom length calculations.

6. 6.

   During a windy day, the crane’s load moment indicator shows overload conditions while trying to lift a load. The wind speed exceeds safety limits. Calculate the necessary steps to ensure safe operation.

   Hint

   Monitor wind conditions and prioritize safety protocols.
