Abstract

The invention relates to an elevator system (10) comprising an elevator car (12), a drive mechanism (14), a belt-like transmission means (13) and one or two counterweights. The drive mechanism (14) is stationary and the transmission means is advantageously configured in the form of a V-ribbed belt (13) cooperating with the drive mechanism (14) in order to move the elevator car (12) by transmitting a force in a frictionally engaging manner. The transmission means (belt) may be reinforced with chemical fibers, preferably made of zylon (PBO).

Claims (18)

1. Lift system (10) with a drive (14) which co-operates with a lift cage (12) and a counterweight (15) by way of a transmission means (13, 33) in order to move the lift cage (12) and the counterweight (15) by transmission of a force, characterised in that the transmission means (13, 33) is constructed as a wedge-ribbed belt (13), in which the groove angle (b) lies between 80 degrees and a 100 degrees.
2. Lift system (10) according to claim 1, characterised in that the drive (14) is stationary.
3. Lift system (10) according to claim 1 or 2, characterised in that the stationary drive (14) is mounted in or at a lift shaft (11) or in an engine room.
4. Lift system (10) according to one or more of the preceding claims, characterised in that the wedge-ribbed belt (13) is provided on at least one side with a plurality of parallelly extending grooves (5).
5. Lift system (10) according to one or more of the preceding claims, characterised in that the groove angle (b) is 90 degrees.
6. Lift system (10) according to one or more of the preceding claims, characterised in that the wedge-ribbed belt (13) has transverse grooves (3).
7. Lift system (10) according to one or more of the preceding claims, characterised in that the wedge-ribbed belt (13) has a guide rib (2) on the rear side.
8. Lift system (10) according to one or more of the preceding claims, characterised in that one or more separate wedge-ribbed belts (13) are provided as transmission means.
9. Lift system (10) according to one or more of the preceding claims, characterised in that the wedge-ribbed belts (13) serve as support means and drive means.
10. Lift system (10) according to one of claims 1 to 9, characterised in that separate support means (13) are present in order to connect the lift cage (12) with a counterweight (15).
11. Lift system (10) according to one or more of the preceding claims, characterised in that the drive (14) for driving the transmission means (13) comprises a drive pulley (16.1) with a diameter of 70 millimetres to 100 millimetres,
12. Belt-like transmission means (13) for a lift (10), which serves as support means (13) and/or drive means (13) for a lift cage (12) with or without a counterweight (15), characterised in that the belt-like transmission means (13) contains strand-shaped tensile carriers (1) of'Zylon' (poly(p-phenylene-2,6-benzobisoxazole)).
13. Belt-like transmission means (13,50) for a lift (10), which serves as support means (13) and/or drive means (13) for a lift cage (12) with or without a counterweight (15), characterised in that the belt-like transmission means (50) has at least one areal tensile layer (51) which extends over substantially the entire belt length and the entire belt width and which is connected over the whole area or part of the area and directly or by way of an intermediate layer (56) with an outer friction layer (52).
14. Belt-like transmission means (13,50) according to claim 13, characterised in that the areal tensile layer (51) consists of a polyamide film.
15. Belt-like transmission means (13,50) according to claim 13, characterised in that the areal layer (51) is a synthetic material film reinforced by chemical fibres.
16. Belt-like transmission means (13,50) according to claim 15, characterised in that the areal tensile layer (51) is reinforced by 'Zylon' (poly(p-phenylene-2,6-benzobisoxazole)) fibres which are embedded in the synthetic material matrix of the film.
17. Belt-like transmission means (13) according to one of claims 12 to 16, characterised in that the transmission means (13) has one or more wedge ribs.
18. Belt-like transmission means (13,50) according to one of claims 12 to 16, characterised in that it has the form of a flat belt (50).
