How is mobile crane lift capacity calculated?

(r)(hC)/100, where r is the radius (distance along the ground to the load) and hC is lifting height times capacity. Capacity, in turn, is particular to each boom arm length and angle chosen, and must be looked up in a table such as the one in the Resources.

How do you calculate lift capacity of a crane?

Measuring the dimensions of this triangle will allow you to achieve an accurate crane load calculation.

  1. The standard calculation for maximum crane capacity is (r)(hC)/100.
  2. R = Radius between the ground and load.
  3. hC = Lifting height multiplied by the capacity.

How do you calculate load lifting capacity?

Take the total weight of the load and divide this by the number of legs supporting the load. For example, assume a 2,000 pound load is to be supported by 2 legs of a sling. The above will give a total minimum weight on each leg of the sling of 2,000 pounds divided by 2 legs or 1,000 pounds.
