5.1. Conditions Affecting Lifting Capacity

Try these first

1. 1.

   What should be checked before extending outriggers?

   Hint

   Think about what stabilizes a crane.

2. 2.

   How far should a crane stay from power lines?

   Hint

   Remember the safety rule in crane operations.

3. 3.

   What is the minimum distance a crane should maintain from high voltage power lines?

   • 1 meter
   • 3 meters
   • 5 meters

   Hint

   Think safety first!

4. 4.

   True or False: Lifting capacity of a crane increases with the distance from the base.

   • True
   • False

   Hint

   Consider how weight distribution works.

5. 5.

   A crane is set to lift a 10,000 kg load at an operational radius of 25 meters. If the recommended load capacity at this radius is 12,000 kg, what actions should the operator take if the wind begins to exceed 30 km/h?

   Hint

   Consider the wind limits set in operations.

6. 6.

   Using a crane that has a rated lifting capacity of 15,000 kg, how would the operator adjust for a load that includes rigging weighing 2,500 kg?

   Hint

   Remember to include all necessary equipment's weight.
