1.3. Load Moment Indicators

Try these first

1. 1.

   What safety features should be checked before operating a crane?

   Hint

   Think about the stability requirements for cranes.

2. 2.

   What is the purpose of load moment indicators?

   Hint

   Consider what information the operator needs during lifting.

3. 3.

   What is the primary function of load moment indicators?

   • To increase the lifting capacity
   • To alarm when overloaded
   • To stabilize the crane

   Hint

   Think about the monitoring roles a crane operator must manage.

4. 4.

   True or False: OSHA allows cranes to operate within 2 meters of high voltage lines.

   • True
   • False

   Hint

   Recall the safety distances mentioned in guidelines.

5. 5.

   A construction site requires lifting a load with a height of 30 meters and an operational radius of 25 meters. How would you determine the necessary boom length using a crane range diagram?

   Hint

   Ensure to understand how both dimensions interact on the diagram.

6. 6.

   Given a crane with a maximum lifting capacity of 15000 kg at a 10-meter radius, calculate the maximum net weight that can be lifted if the rigging accessories weigh 1500 kg.

   Hint

   Focus on understanding the total lifting capacity versus actual load being lifted.
