5.2. Stability and Crane Ratings

Try these first

1. 1.

   What is the purpose of outriggers for cranes?

   Hint

   Think about the stability of the crane.

2. 2.

   Name one safety guideline related to high voltage lines.

   Hint

   Remember OSHA regulations!

3. 3.

   What role do outriggers play in crane stability?

   • They are optional
   • They stabilize the crane
   • They increase load capacity

   Hint

   Consider why they are critical during lifts.

4. 4.

   True or False: Crane operations should continue even in high winds if the operator feels confident.

   • True
   • False

   Hint

   What does safety dictate in adverse conditions?

5. 5.

   Given a load of 10,000 kg to be lifted to a height of 50 meters from 25 meters away, calculate the required boom length and evaluate its safety against known load capacity charts.

   Hint

   Refer to load capacity charts to verify the lifting capacity.

6. 6.

   You are operating a crane in windy conditions. The wind speed averages around 80 km/h. Devise a safe operational plan considering OSHA guidelines.

   Hint

   OSHA guidelines specify a maximum wind speed for safe crane operations.
