摘要： A method of making an elevator load bearing member includes unidirectional weaving a plurality of load bearing fibers including at least a first material and a second material. A melting point of the first material is higher than a melting point of the second material. The method includes bonding the load bearing fibers together by at least partially melting at least some of the second material and coating the plurality of load bearing fibers.

摘要： A belt-shaped rope of a hoisting device, the rope being substantially larger in its width-direction than thickness-direction, and comprising two or more load bearing members; a coating forming an outer surface of the rope, in which coating the two or more load bearing members are embedded, wherein the two or more load bearing members are oriented to extend parallel with longitudinal direction of the rope adjacent each other in width direction of the rope such that a gap is formed in width direction between load bearing members next to each other, the coating extending into the gap. The coating comprises a first coating portion between load bearing members next to each other, and a second coating portion forming an outer side of the rope facing in thickness direction of the rope, and in that the material of the first coating portion is substantially harder than the material of the second coating portion.

摘要： A strap includes at least a first and second area, the first and second areas being consecutive along a longitudinal axis of the strap. The strap is woven from at least the first, second and third groups of warp threads and at least one weft thread, the strap being devoid of the second group in the second area, and of the third group in the first area, the first group passing through the first and second areas. The first group and second group of warp threads are distributed over the width of the strap in the first area.

摘要： A fall arrest system includes a line retraction device having a safety line, an energy absorber configured for connecting to a terminal end of the safety line, and a harness configured for connecting to the energy absorber such that the energy absorber is disposed between the terminal end of the safety line and the harness. The safety line is selected to have a predetermined mean breaking force with a first standard deviation, and the energy absorber is selected to have a predetermined mean deployment force with a second standard deviation. The mean breaking force of the safety line and the mean deployment force of the energy absorber overlap over an overlapping region of the first and second standard deviation. A ratio of an overlap mean force of the overlapping region to an overlap standard deviation of the overlapping region is less than or equal to 6.
