    • A fall arrest line anchor for releasably securing to a rail of a railway. The anchor comprises a pair of plates, each comprising an upper, flat portion and a lower portion curved so that, when the plates are in anchoring position with their flat portions secured together in abutting relationship, the curved portions circumscribe a sufficient portion of the crown of the rail so as to prevent unpurposeful disengagement, a plurality of apertures in the flat portions alignable, when the plates are in anchoring position, to releasably receive means to attach and secure the plates together and a hook of a workmen's fall arrest line.

    • A load-handling device comprising a pair of pulley assemblies each having a body, at least one pulley supported by the body, and having a peripheral outer surface, a rope secured at one end to a support structure and entrained about each of the outer surfaces to interconnect the pulleys in a load-handling arrangement. Each of the pulley assemblies include a one way clutch acting between the body and the pulley to inhibit rotation relative to the body in one direction. The surfaces of the pulleys thereby providing frictional engagement for the rope in the one direction to facilitate handling of the load.

    • A rail bridge rescue frame comprises three elongated legs having upper and lower ends. The upper ends are secured to a head assembly so as to universally pivot with respect thereto. Two of the legs are forward legs of shorter and similar length and the third is a rear leg of longer length. Means are secured to the lower end of each of the forward legs to bear against a side portion of a rail. Means are attached to the lower end of the rear leg to secure to a portion of a rail. The frame is constructed so that when the rear leg is secured to one rail of a railway and the lower ends of the forward legs are bearing against outer portions of an adjacent rail thereof, the head assembly will be positioned clear of the railway to one side to provide support for a line to lift a person or the like below the railway up to the level of the railway.

    • An energy absorber for a horizontal lifeline protection system is provided. The energy absorber comprises a pair of independent shock absorbing units of similar construction. Each unit comprises a strip of woven webbing material and a strip of tear-ply webbing material. Each pair of corresponding ends of these strips are secured to each other and to a ring for securing to a portion of the horizontal lifeline fall protection system. The corresponding pairs of rings at each end are secured to each other. The woven webbing and tear-ply webbing of the units are folded and encased within a tearable envelope. The absorber is constructed so as to be secured to a horizontal lifeline within a fall protection system so that when a predetermined force is applied to the rings, the envelope tears and the tear-ply webbing separates, resulting in an overall elongation of the absorber. In the event the tear-ply webbing separates completely, the remaining force is applied to the woven webbing.
    • 提供了一种用于水平救生索保护系统的能量吸收器。 能量吸收器包括一对具有类似结构的独立的冲击吸收单元。 每个单元包括编织织带材料条和一层撕裂织带材料。 这些条带的每对相应的端部彼此固定并固定到环上,以固定到水平救生索坠落保护系统的一部分。 每个端部的相应的环对彼此固定。 单元的编织织带和撕裂织带被折叠并包裹在可撕裂的信封内。 吸收器被构造成在坠落保护系统内被固定到水平救生索上,使得当预定的力施加到环上时,信封撕裂和撕开的织带分离,导致吸收体的总伸长。 在撕开的织带完全分离的情况下,剩余的力被施加到编织织带上。

    • The invention comprises a multi-functional worker's harness of the type comprising interacting shoulder and sub-pelvic harnesses. The shoulder strap comprises a pair of interacting strap sections, which are not attached to each other. Each strap section has a pair of ends secured to a releasable buckle and each section, when in position on a wearer, extends from one end at an opposite side near the wearer's waist at the front, over the opposite shoulder of the wearer, down the wearer's back and around the wearer's side to the other end of that section at a point on the same side as it is positioned on the front. The sections, where they cross over each other at each of the front and back, pass through and are held in overlapping fashion by a friction buckle. The sub-pelvic strap comprises a pair of strap sections, each having a pair of ends secured to releasable buckle to cooperate with a corresponding buckle of the shoulder strap sections. Each of the strap sections of the sub-pelvic strap are of a length to permit wrapping about a different one of a worker's legs and its ends to be buckled to corresponding end buckles of a corresponding one of the shoulder strap sections. A further strap section is secured to and extends between intermediate portions of the sub-pelvic sections and is intended to rest behind the wearer's seat when in position. A corresponding pair of the buckles are provided with adjustment means to permit symmetrical adjustment of the strap section lengths when in position on the wearer.
