FIELD: lifting facilities. SUBSTANCE: invention relates to design of cable used in lifts and elevators which is connected with cabin and counterweight. Cable consists of load-carrying strands made of artificial fiber. Outer layer of strands is covered by closed sheath made of synthetic material, and load-carrying strands are wound in several layers on core. Closed round synthetic sheath fills up spaces between carrying strands of outer layer from side of cable outer perimeter. Friction decreasing sheath can be placed between outer layer and inner layer of strands. Cable can be provided with filler strands between layers of artificial fiber strands. Carrying strands can be twisted of aromatic polyamide fibers and impregnated with solution of polyurethane containing 10-60% of polyurethane, and outer surface of sheath of cable can be made smooth or structurized. EFFECT: possibility of application of heavy shearing force, increased service life of cable. 7 cl, 5 dwg
