How do you calculate counterweight on a crane?
Mobile Crane Counterweight Calculation
Because the forces are applied at 90° angles, the sinθ component would equal sin(90°), or 1. Using the equation, Fe × de = Fl × dl, the torque for the weight, or effort force, is then 2,000 pounds times 50 feet, or 100,000 pound-feet for the weight.
How much does a 300 ton crane weight?
Standard, consisting of 2,300 lbs. (1 043 kg) on superstructure. Optional: 8,460 lbs. (3 837 kg) heavy counterweight package.
