Disclosed is a shock absorption device including a dual fall prevention band connected to a safety rope connected to a safety harness that a worker wears. The shock absorption device including the dual fall prevention band includes a dual fall prevention band and a shock absorption band. The dual fall prevention band is shaped like a closed loop by coupling opposite ends thereof through a first seam, and the first ring, the second ring, a third ring, and a fourth ring are formed by coupling parts of the dual fall prevention band that face each other at a first position to each other through a second seam, and coupling parts of the dual fall prevention band that face each other at a second position to each other through a third seam.

The present disclosure relates to the technical field of weaving, and provides an energy absorber, a method for weaving the energy absorber, and a weaving device. The energy absorber includes a first split section, a first single strand section, a second split section, a second single strand section, and a third split section which are connected in sequence, the first split section and the third split section each include at least two sub-woven belts, the at least two sub-woven belts are separated from each other, at least one of the at least two sub-woven belts is capable of being stretched and contracted under an action of an external force, the first split section, the first single strand section, the second split section, the second single strand section, and the third split section are integrally woven.

There is provided a height rescue apparatus comprising a safety line (1) which is attached at (3) to a flexible elongate element (2) which has a lower tensile strength than the safety line 1 which is wound on a drum (9) which is part of a speed control means. A friction device (5) acts on a portion of the safety line (1) to reduce tension in said portion of the safety line by at least 50% in a full arrest situation. The drum (9) or the speed control means is held in a first position which prevents rotation of the drum and release means can be actuated after the fall arrest to allow the drum to provide a controlled lowering action.
