Zusammenfassung: | Roofing edge fall arrest apparatus 11 is disclosed for use when laying roofing materials on purlins (4, figure 1) of a building, e.g. a steel construction. It includes fall arrest panels 12 arrangeable between the purlins. A beam 21 is arranged to cross over a number of purlins, the panels being fasted to the beam. Supports, preferably in the form of sliders or rollers (20, figure 4), movably hold the structure on the purlins. Furthermore, the apparatus comprises means to locate the structure on the purlins longitudinally to the beam, preferably by additional sliders or rollers. The support is set in from the ends of the fall arrest panels, supporting them in a cantilevered manner. The panels may include an edge frame with a netting or a steel work spanning the frame. The beam is a steel work truss, which can be stiff within its plane yet flexible over its length to follow any curvature of the roof, or stiff over its length for use with a flat roof. The apparatus may comprise brakes (31, figure 5) like ropes or wires to secure against movement of the apparatus. |
