Counter Weight Formula

W = Counterweight
L = Load Capacity Of Hoist
a = Arm Reach
b = Backspan Distance (Distance between the fulcrum point and the center of the counterweights)
4 = Safety Factor (4: 1)

Note: Counterweights must be a nonflowable material, and they must be attached to the outrigger beam

Always use taut tieback wire ropes capable of holding the full load.

W = (La)4/b
