Wheel load calculation of crane

Calculation of crane related

The crane wheel load, usually referred to as maximum wheel load is the total load in pounds that any single crane wheel will see. The formula for determining MWL is Bridge weight / 2 + {Live load ( crane capacity + hoist weight) x 15%impact*)/ Number of wheels on a single end truck. For a top running 5-ton capacity crane, with a bridge weight of 8000 lbs. and a hoist that weights 900 lbs. with four wheels total:

8000/2+(10000+9000x1.15)/2=12925
