Problems solved by technology

[0009] Disadvantages in flat cable trains, however, are the special manufacturing and storage requirements and the high cost of carrying devices for all load-carrying sizes
Furthermore, incipient damage to the support means presents a real risk to the operation of the elevator and even to safety, and the detection of incipient damage with little or no technical effort

Embodiment Construction

[0025] A known cable-operated drive with double winding is shown in detail in FIG. 1 . A set of load-carrying cables 1 in this embodiment consists of 8 parallel-extending flat load-bearing cables with a nominal diameter of 6 mm. guide, while extending to the secondary pulley also with a nominal diameter of 240 mm, winding the secondary pulley 3, extending back to the drive pulley 2, winding the drive pulley 2, returning to the secondary pulley 3, in the secondary Pulley 3 again guides its downward extension. It is also possible to use a drive pulley with a smaller nominal diameter instead of the drive pulley with a nominal diameter of 240mm. For example, the nominal diameter is only equal to 180 mm, which corresponds to a ratio of 30 between the diameter of the drive pulley and the nominal diameter of the carrying cable.

[0026] Referring to Fig. 1a, only one cable of the eight load-bearing cables of the load-bearing cable set 1 is shown in the figure. The transmission pul...

Abstract

The invention relates to a gearless cable lift with a drive disk mechanism which is dually wound by several bearer cables, comprising a counter disk (3), an elevator car (6), guide tracks for the elevator car (6) and a counter weight, especially for installation without a machine room. According to the invention, the bearer cables are guided in semicircular grooves and the ratio of the drive disk diameter to the nominal diameter of the bearing cables is <= 40.

Description

technical field [0001] The invention relates to a gearless cable-operated elevator having a transmission pulley drive device double-wound by several parallel load-carrying cables, and having a secondary pulley, a car, guide rails for said car, and a counterweight, said elevator apparatus Facilitates installation without a power room. Background technique [0002] In a cable-operated elevator, the car and counterweight are connected to each other by carrying means "cables". The counterweight is balanced against the dead weight of the car, at least half of the partial payload and half of the dead weight of the elevator ropes connecting the car. For safety reasons, there must be at least two load-carrying cables running in parallel. Currently, cable-operated elevators are equipped with drive pulley drives, which replace the cable reel drives used in the past, wherein the drive pulleys also serve as drive rims. An electric motor is used as a drive. The main components of gea...
