Related evaluation and reporting of this complaint was done during retrospective review as part of capa 22-0074 corrective action 12.The customer complaint could be confirmed.The actual cause of the crack in the ropes in/on the control mechanism cannot be named with absolute certainty, as a material defect in the wire rope hoists or pre-damage during damage during assembly cannot be ruled out.However, it is certain that the installed wire rope hoists show considerable detachment of the coating in the shaft and distal area.These detachments lead to an increased coefficient of friction within the rope pull guides and in the flexible angular range, which results in significantly increased force during use in the form of significantly increased force required for control.This means that the increased force can lead to a crack in the rope.The problem was addressed within capa19-0003.The event is filed under internal karl storz complaint id (b)(4).
