4. Summary of Crane Types

Try these first

1. 1.

   What is the role of outriggers in crane operations?

   Hint

   Think about how a tripod functions.

2. 2.

   What minimum distance should cranes maintain from high-voltage lines, according to OSHA?

   Hint

   OSHA sets safety standards!

3. 3.

   What is the primary purpose of outriggers?

   • A) Add weight to the crane
   • B) Increase stability
   • C) Speed up the operation

   Hint

   Think about the primary function of supports and bases.

4. 4.

   True or False: Load moment indicators are not necessary in modern cranes.

   • True
   • False

   Hint

   Rethink the safety features of machinery.

5. 5.

   You need to lift a load weighing 15,000 kg up to a height of 45 meters at an operational radius of 25 meters. Given the crane’s limits of 20,000 kg at that radius, how can you ensure the operation remains safe?

   Hint

   Always consider the entire weight, including rigging, when calculating lifting capacity.

6. 6.

   A crane is operating on soft soil and shows signs of instability. What steps should you take to enhance its safety?

   Hint

   Evaluate both the ground and equipment configurations to enhance safety.
