  • Patent number: 7650717
    Abstract: A belt device for arrangements which are put under tensile load, particularly for systems for the securing of tree crowns, having a belt (10) with a loop at each end (12, 12?) which is formed by turning over the end parts of the belt (10) and fastening the ends to the belt, wherein the fastenings (14, 14?) and the belt (10) are adapted to withstand a pre-determined minimum tensile force. In order to guarantee a good visibility of the indicating element even from greater distances, it is proposed by the invention that the belt (10) is overlapped by an indicating element (16) in the vicinity of at least one of the loops (12), which indicating element shortens the belt (10) and is fastened with two end portions on the belt (10) such that one of the fastenings (18) gives way when a pre-determined tensile force acts on the belt (10), the tensile force being smaller than the minimum tensile force which the loop fastenings (14, 14?) and the belt withstand.
