Any good mechanical engineer can determine the calculated lifting capacity of the rig as long as he knows the operating pressure of the hydraulics, the diameter of the lift piston, the rotation radius of the lift piston, the rotation radius of the lift arm, the rotation radius of the input side of the rear rock shaft, and the rotation radius of the crane. He can also determine if the capacity of the crane is exceeded by the hydraulic lift system. He has to understand that rotation radius is not equal to the length of the rotation arm but the perpendicular distance from the center of the rock shaft to the action rod (IE center of the hydraulic piston). That radius will change for all rotation arms as the lift acts through a rotation cycle. Advanced math (Analytical Geometry) can be used to calculate the maximum and minimum lift capacity or it can be found by graphical means by making the calculation for several points in the lift cycle. This is so much junk for most but some of us like this stuff.
