3. 3.

   What is the main disadvantage of telescopic boom cranes?

   • High lifting capacity
   • Reduced lifting capacity
   • Low costs

   Hint

   Consider the construction materials used.

4. 4.

   True or False: Proper use of outriggers can increase the lifting capacity of a telescopic crane.

   • True
   • False

   Hint

   Think of how stability relates to lifting.
