What is the over-turning moment?
Think about what causes an object to tip over.
Define the operating radius.
It involves the load's position relative to the crane's base.
What does the term 'tipping load' refer to?
Think of the weight limits associated with crane operation.
True or False: The stabilizing moment only accounts for the crane’s weight.
Remember to think about what contributes to stability.
For a crane with a tipping load of 25 tons, operating radius of 40 feet, and a boom weight of 8 tons, calculate the total weight including all factors that must not exceed to prevent tipping.
Think about how the total tipping load is allocated among various components.
A crane has a stabilizing moment of 60 tons. If it lifts a load of 15 tons with a boom weight of 4 tons, what additional equipment should be accounted for to maintain balance?
Remember to add up all contributions to the weight affecting the tipping moment.
