Abstract
A round load lifting sling composed of an endless skein of threads as a load bearing core and a textile protective tube surrounding the endless skein, the endless skein carrying along a testing conductor which is connected with two connecting contacts which penetrate the wall of the protective tube for connection to a source of testing medium to flow through the testing conductor. Damage or severance of the threads of the skein is detectable by an interruption in flow of the medium due to accompanying damage or severance of the conductor.
