FIELD: transport.
SUBSTANCE: invention relates to lifting devices. Proposed device comprises drum provided with spring mounted in bearings on machine first element, flexible element to interact with said drum and embrace it that has its first end fastened to machine second structural element, braking device articulated with said drum to increase braking force in increase of the drum angular speed. Said drum is articulated with motion pickup and equipped with rotary connector connected with power source and second end of aforesaid flexible element. Braking device can absorb spring energy when flexible element is broken or rolls off the drum.
EFFECT: higher safety, expanded operating performances.
