FIELD: textile; paper.
SUBSTANCE: rope (1) from synthetic fibres consists of twisted strands (7,8,9,10) arranged in at least one layer (2,3,4). In the rope (1) of synthetic fibres the strands of one layer are mutually distant from each other. Due to the distance (d1), at which the strands are arranged from each other, strands (7) of the external layer (2) in radial direction (r) are arranged with the possibility of free movement in direction of the rope centre and radial pressure at the strands (8, 9) of the first internal layer (3). Radial pressure from a layer to a layer increases to inside. Also a bearing and a driving facility is proposed for a lift, at least with two ropes described above, closed by a joint solid shell, a lift device and the method of rope manufacturing.
EFFECT: extended service life of the rope and reliability in operation.
