4.4. Rigging Safety

Try these first

1. 1.

   What is the function of an articulated jib crane?

   Hint

   Think about its flexibility.

2. 2.

   Within what range is the maximum free-standing height for tower cranes?

   Hint

   Consider the structural limitations discussed.

3. 3.

   What is the main advantage of using an articulated jib in tower cranes?

   • It decreases horizontal reach
   • It increases flexibility in lifting
   • It maintains the same reach

   Hint

   Focus on what flexibility means in the lifting context.

4. 4.

   True or False: The maximum allowed height for tower cranes is 300 meters without structural support.

   • True
   • False

   Hint

   Identify the limits discussed.

5. 5.

   A site plan requires the use of a climbing crane in a building exceeding 300 meters in height. Discuss the implications and possible solutions for rigging safety at such heights.

   Hint

   Focus on cranes suited for tall structures.

6. 6.

   You are tasked with rigging a load that is unstable due to its center of gravity being off-center. What methods can you employ to ensure stable lifting?

   Hint

   Think about how to balance the load effectively.
