FIELD: design of jib-type self-propelled cranes. SUBSTANCE: between frame of running gear of crane and supporting and traversing device with circular symmetry there are three universal tension-compression power measuring transducers. For automatic determination of actual production capacity of crane and mode of operation of its mechanisms crane is provided with system of processing of signals power measuring transducers which have timer clock and production capacity and mode of operation counters. EFFECT: improved capacity measuring system. 2 cl, 2 dwg
