Abstract
A load tensiometer transducer, a boom angle transducer and a boom length transducer are operatively connected to a telescopic variable boom length and crane product. Boom load, angle and length analog signal control logic, responsive to the signals of each transducer, receives, amplifies, and converts the signals into corresponding digital signals that are continuously processed with data read from one of a plurality of selected memory circuits in which information based on the configuration of the crane in use is stored. Digital output signals are produced by the control logic for use in operating a digital radius readout, allowable load readout, and actual load readout, respectively.
