4.2. Effects of Poor Soil Conditions

Try these first

1. 1.

   What are outriggers?

   Hint

   Think about how cranes prevent tipping.

2. 2.

   Why is the center of gravity important?

   Hint

   Consider where the crane's weight is balanced.

3. 3.

   What is the main purpose of outriggers?

   • To increase lifting capacity
   • To stabilize the crane
   • To reduce weight

   Hint

   Consider what keeps cranes steady.

4. 4.

   True or False: Poor soil conditions can lead to an increase in tipping risk.

   • True
   • False

   Hint

   Think about the effect of weight on unstable ground.

5. 5.

   A crane is rated for 200 tons but is set up on soft clay. How should the lifting operations be adjusted?

   Hint

   Consider the crane's balance and safety margins.

6. 6.

   If a crane without outriggers is lifting a load that would normally require three outriggers, what safety measures should be taken?

   Hint

   Think about the implications on load distribution and balance.
