7. Conclusion and Next Steps

Try these first

1. 1.

   What is the working load of a crane?

   Hint

   Think about the factors that influence stability.

2. 2.

   Name one factor that affects crane stability.

   Hint

   Consider how the crane’s position affects its ability to lift.

3. 3.

   What does the variable 'R' represent in crane equations?

   • The crane's weight
   • Operating radius
   • The load line

   Hint

   Remember the relationship between distance and lifting capacity.

4. 4.

   Using outriggers can double the lifting capacity of a crane.

   • True
   • False

   Hint

   Consider what outriggers do rather than their effect on the weight.

5. 5.

   A crane's tipping load is 120 tons. If it's operating with a safety margin of 75%, what is the man safe working load?

   Hint

   Use the tipping load as a starting point to find the working load.

6. 6.

   If two different cranes, a crawler and a truck-mounted crane, are rated at 80 tons and 60 tons respectively, how much load can they lift combined when using outriggers?

   Hint

   Think about how outriggers directly enhance the capacity allowed for lifting.
