Abstract: The lift system comprises drive unit propelled by driving wheel, and a lift carrier unit, which carries lift cage. The carrier unit has a rib arrangement on the driving wheel, which is turned towards traction side, and a carrier band on the traction side turned away from belt back side. The rib arrangement has two ribs (13) extending in longitudinal direction of the carrier unit. The rib arrangement has a traction carrier arrangement with traction carriers (14) arranged in the rib. The ribs are fastened to the carrier band. The lift system comprises drive unit propelled by driving wheel, and a lift carrier unit, which carries lift cage. The carrier unit has a rib arrangement on the driving wheel, which is turned towards traction side, and a carrier band on the traction side turned away from belt back side. The rib arrangement has two ribs (13) extending in longitudinal direction of the carrier unit. The rib arrangement has a traction carrier arrangement with traction carriers (14) arranged in the ribs, which are fastened to the carrier band. A groove (16) is formed between the two adjacent ribs of the rib arrangement and reaches up to the carrier band. The ribs have a contact section (13.1) with a trapezoidal cross-section arranged to corresponding grooves of the driving wheel in interference, and a base section (13.2) with a rectangular-shaped cross section arranged between the contact section and the carrier band. The traction carriers are arranged in the ribs and contact the carrier band. The traction carriers are formed as low-end wire and/or are built from stranded wire made of steel and/or plastic wires. The ribs are made of a first material with a hardness of 80-85 shore (A), and a wedge-shaped and/or trapezoidal-shaped cross section with a flank angle of 80-100[deg] . The carrier band is made of a second material. Independent claims are included for: (1) a lift carrier unit for lift system; and (2) a production method for lift-carrier unit.

Abstract: Claimed is an extruded belt to lift and lower a lift (elevator) cabin. The belt consists of an elongated backing strip (13) with embedded steel wires (14.1) in pairs under a series of truncated elastic (15) (15.1) profiles (15.1). Each wire of a pair is separated from the adjacent wire by a polymer profile of circular or dumbbell cross section. Each pair of wires is separated from the adjacent pair by a polymer block of essentially rectangular cross section.

Abstract: 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.

Abstract: The method involves manufacturing a belt part (13), where the belt part has grooves extending in a longitudinal direction of a belt (12). A tension member (14) is arranged in the grooves. Another belt part (15) is connected with the former belt part so that the tension member is received in the interior of the belt, where the latter belt part has a hardness of 80 to 85 shore. The tension member is designed as a wire or a rope from individual steel wires and/or synthetic fibers. The belt parts are connected with each other by extrusion and/or bonding. An independent claim is also included for a belt for a lift system comprising belt parts.

Abstract: The belt (12) comprises three parts. The first part is a belt made from a first material (13), a thermoplastic. The second is a tensile load-bearing reinforcement (14) of single- or stranded steel wires, embedded in the first part. The third part is a second belt (15) made of a second material. The first material is polyamide (PA), polyethylene (PE), polycarbonate (PC), polyvinyl chloride (PVC) or a polyblend containing one of these, or a fabric of one of these materials. The first material has a minimum yield stress in accordance with DIN 53455 or ISO 527 of 45 N/mm 2>, a minimal elongation at rupture in accordance with the same standards, of 45%, and a minimum ball indentation hardness in accordance with DIN 53456 or ISO 2039 (H358/30) of 70N/mm 2>. All foregoing measurements are made at room temperature. Thickness of the first part is preferably 30% at most, of the overall belt thickness. The second part has a traction area working with a drive wheel of the elevator plant, which is ribbed. It has a defined coefficient of friction, preferably higher or lower than that of the second material. The second material is an elastomer, especially polyurethane (PU), polychloroprene (CR) and/or ethylene propylene diene rubber (EPDM). The Shore A hardness of the second material at room temperature is preferably less than 85. The ridges have trapezoidal or V-profiles with an essentially rectangular base section between the contact sections and the first part. They comprise at least 25% of the height of the second part. The base sections are separated by intermediate spaces. An independent claim IS INCLUDED FOR the method of manufacture.
