FIELD: transport.
SUBSTANCE: changes in coordinates of cargo in space vs time are set for travelling crane as well as compensation for uncontrolled cargo spatial path. At every time moment of displacement start, transducers measure actual current orthogonal coordinates of the cargo. Crane onboard computer compares accrual coordinates of the cargo with required coordinates at every time moment and processes both with the help of claimed relationships. Said computer computes and generates control instructions for crane gantry and trolley drives. Crane drives displace cargo suspension point in horizontal directions opposite departures of cargo actual coordinates relative to those of the point of required path.
EFFECT: higher accuracy and efficiency.
