FIELD: mechanical engineering; crane-manipulator plants.
SUBSTANCE: invention relates to load-lifting machines with boom equipment and it can be used for evaluation of strength of structural members of grab-type mounted devices used with cranes and selection of material, geometric, mass-inertia and power parameters of said devices. According to proposed method, analytic dependences are used relaying geometric, mass-inertia and kinematic parameters of structural members of crane-manipulator plant and load with value of determined forces and moments.
EFFECT: increased accuracy of determination of dynamic loads acting onto structural members of crane-manipulator plant handling long-cut loads.
