1.2. Lifting Capacity Charts

Try these first

1. 1.

   What are outriggers used for?

   Hint

   Think about how cranes need support during lifting.

2. 2.

   At what wind speed should crane operations cease?

   Hint

   Consider safety in windy conditions.

3. 3.

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

   • 1 meter
   • 3 meters
   • 5 meters

   Hint

   Remember safety distances around electricity.

4. 4.

   True or False: The lifting capacity of a crane increases as the operating radius extends.

   • True
   • False

   Hint

   Consider how distance impacts weight capabilities.

5. 5.

   A crane must lift a 10,000 kg load to a height of 50 meters from a point that is 25 meters away from the center of rotation. Determine the minimum boom length required using the range diagram, and describe the safety measures to consider during this operation.

   Hint

   Don't forget to consider all parameters when making your calculations.

6. 6.

   If the load moment indicator warns you of an overload during a lift, explain the immediate steps you would take as the operator to ensure safety.

   Hint

   Think about what safety protocols to follow when alerted.
