  • SYSTEM AS ATTACHMENT POSSIBILITY FOR SAFETY EQUIPMENT TO ARREST FALLS
    Publication number: 20090205904
    Abstract: A System as attachment possibility for safety equipments to arrest falls produced by attachment points or, respectively, guide lines or rails secured by a weighting load, is designed so that a disk with a large area of adaptable size and form is composed of individual elements with a small area which are designed to be connected together. Said disk is arranged to be covered with a weighting load (as for example a bulk material, plates or the like) and is accordingly able to take up forces as occur in the case of arresting a fall by way of attachment points applied to it or integrated in individual elements.
