摘要

The invention relates to the gripping devices, which are suspended on the hook of the jib crane, in particular, for pulling of hook at installation of crane jib with hydraulic drive into transport position, when excess tension force can lead to the deformation of jib. A transport hoist cable contains a housing with a clamp for mounting on the hook of crane, a rope with loops at the ends mounted in the housing and blocks wrapped by rope with axles fixed relative to the housing and runners with spring-loaded axles. In accordance with the invention, the axles of runners are connected by common springs of tension with possibility of changing the length of springs. The length of rope is nominal and constant. The invention provides elimination of the danger of excess effort of pulling of hook into transport position with appropriate tension of transport tie-rope, made in compact overall sizes.
