FIELD: transport. ^ SUBSTANCE: method envisages preliminary determining or setting of admissible values of parameters characterising loading and/or attitude position of outrigger or crane cargo-handling device, memorising this data, measuring of these parameters during crane operation, comparing of measured values with admissible values, and further forming of control signals or blocking of control by execution units in order to prevent exceeding of admissible values. Prior to commencement of crane work or in process of lifting and movement of cargoes crane-operator additionally performs preliminary visual control of crane operation condition or presence of people along way of crane or cargo movement or automatic control of correctness of slinging (securing) of cargo, or automatic check of correctness of crane installation on outriggers or optical measurement of crane performance parameters or automatic change of coordinate parity parameters using GPS receivers, radio-frequency or inertial determination of position devices located on obstacles, clothing or equipment of people. Results of this check or control ensue implementation of additional control or information signals. ^ EFFECT: enhancement of safety of crane operation and of crane efficiency. ^ 24 cl, 1 dwg |
