Abstract: A tensioning apparatus tensions straps, and in particular is configured to tension belts. In order to achieve good tensioning characteristics, the tensioning apparatus has a dynamically acting element, and by use of the dynamically acting element a transmission of force takes place indirectly in the case of the tensioning apparatus.

Abstract: A protective device to prevent persons from falling has a base and an anchor mast system in connection with the base. On a free upper end of the anchor mast system, personal protective equipment (PPE) is fastened at an anchor point. To increase stability, the anchor mast system is provided with a lower standing section and a cantilever section. The standing section and the cantilever section are pivoted by a pivot drive relative to each other and relative to the base such that the anchor point in connection with the PPE is displaced downwards and away from the tilting edge of the base. This reduces the total height of the protective device, and increases the stability in the event of load in the region of the anchor point, while the weight of the protective device, particular also of the base, is reduced.

Abstract: An anti-fall safeguard for persons includes a supporting base with which the anti-fall safeguard can be set up on an underlying surface formed of individual concrete slabs. The concrete slabs are provided with upwardly projecting iron reinforcing elements and with an anchor mast system which is connected to the supporting base. Personal protective equipment is fastened to the free, upper end of the anchor mast system. In order to securely fasten the anti-fall safeguard on an underlying surface, two or more cable safeguards are provided, which can be brought into connection with the iron reinforcing elements of the concrete slabs. The cable safeguards can be tensioned and the supporting base is immovably secured on the underlying surface by the tensioning of the cable safeguards.
