Often times the calculated load is based on crane extension, boom angle and hydraulic pressure. The control system is constituted by programmable controller, weight sensor, angle sensors, length sensor and electromagnetic unloading valves and the like. For example, if the crane boom lenght is 40 and radius is 11 meter,the how to know about the angle. Near the other end of the boom is a motor driven cable that lifts a container straight up at a constant speed.
