FIELD: transport.
SUBSTANCE: invention relates to safety device incorporated with crane installation. Proposed system comprises braking device to act on transporting device, braking device control component, overload transducer to register overload conditions and generate overload signal, and speed transducer recording speed of transported cargo and generating signal on speed. Control device, in response to overload signal, acts on braking device so that it interlocks transporting device and protects transported cargo. In response to the next signal, transporting device is unlocked so that it displaces under action of transported cargo load into free state. Action of braking device on transporting device is adjusted so that transported cargo is transferred into free state at sufficiently constant speed. Transporting device with control and adjusting system represents a cable lifting installation, crane installation, or component of container installation. Crane installation comprises two transporting devices. Note here that, with container spreader moving up and down, both transporting devices work in synchronism and shares common control system.
EFFECT: overload protection, simplified cargo transportation.
