Patent ID: 7650717

Claim:
A tree tensile load indicating belt device, having a belt ( 10 ) with a loop at each end ( 12 , 12 ′) which loop is formed by turning over the end parts of the belt ( 10 ) and fastening the ends to the belt via fastenings ( 14 , 14 ′), wherein the fastenings ( 14 , 14 ′) and the belt ( 10 ) are adapted to withstand a predetermined minimum tensile force, said belt being a first color, and an indicating element ( 16 ) having a signalling colour different from said first color in the vicinity of at least one of the loops ( 12 ), which indicating element is fastened with fastenings ( 18 , 18 ′) at first and second end portions of the signalling element onto the belt ( 10 ) such that said indicating element ( 16 ) shortens the belt ( 10 ), wherein the load carrying capacity of the fastenings ( 18 , 18 ′) is different, wherein the first indicating element end fastening ( 18 ) is a rated breaking point which yields to a pre-determined load, while the second indicating element end fastening ( 18 ′) withstands higher loads such that the first indicating element end fastening ( 18 ) gives way when a pre-determined tensile force acts on the belt ( 10 ), the tensile force being smaller than said minimum tensile force which the loop fastenings ( 14 , 14 ′) and the belt are adapted to withstand, whereby the indicating element ( 16 ), released at one end and attached at the other end, forms a signal pendant different in color from said first color, wherein one end of said belt device is secured to a tree part to be monitored, and the other end of said belt device is secured to a tree part stronger than the tree part to be monitored.
