The load-bearing mechanism (1) for a lift system, comprises a base body (2), a drive side with two or three drive ribs (3), a deflecting side with a guide rib (4) opposite to the drive side, and a traction carrier arrangement (5) arranged in the base body. Each guide rib has a larger flank height (h4) and/or width (t4) than each drive rib and/or the ratio (h4/w) of the flank height of each guide rib to width (w) of the load-bearing mechanism is 0.4 and/or the flank angle (~a 3) of each drive rib is larger than the flank angle (~a4) of each guide rib. The load-bearing mechanism (1) for a lift system, comprises a base body (2), a drive side with two or three drive ribs (3), a deflecting side with a guide rib (4) opposite to the drive side, and a traction carrier arrangement (5) arranged in the base body. Each guide rib has a larger flank height (h4) and/or width (t4) than each drive rib and/or the ratio (h4/w) of the flank height of each guide rib to width (w) of the load-bearing mechanism is 0.4 and/or the flank angle (~a3) of each drive rib is larger than the flank angle (~a4) of each guide rib and/or three drive ribs are assigned as a guide rib. The ratio of the flank height (h4) of each guide rib to the flank height (h3) of each drive rib is 1.5. The ratio of the flank width (t4) of each guide rib to the flank width (t3) of each drive rib is 1.5. The ratio of the width (w) and height (h1) of the load-bearing mechanism is 0.95. Each drive rib is formed as wedge rib with a flank angle (~a3) of 60-120 deg and each guide rib is formed as wedge rib with a flank angle (~a4) of 60-100 deg . The minimum width (d3) of each drive rib is larger than the minimum width (d20) of an assigned groove of a drive wheel of the lifting system. A groove with a radius (R3) is formed between all joining drive ribs. The drive side and/or the deflecting side have a lining or coating, whose friction coefficient, hardness and/or abrasion resistance differ from the base body. A group with all drive ribs and a group with all guide ribs are formed to each other. The group of the drive ribs has a smaller shore-hardness and/or a larger friction coefficient than the group of the guide ribs. Each drive rib is assigned as two traction carrier, whose diameter is 1.5-4 mm. The distance of the traction carrier arrangement to the drive side is smaller than to the deflection side. Each traction carrier has a double coat core strand with a core wire and two wire coat surrounding core wire, and a single coat core strand formed around the two coat core strand with the core wire and the wire coat. The two wire coats of the core strand have same blow angles and the outside coating contrary to the blow direction of its single wire coat is surrounded around the core strand. Independent claims are included for: (1) a lifting system with a cabin; and (2) procedure for mounting a load-bearing mechanism in lifting system. |
