Safety device for cable car gondolas

Abstract

Safety device for cable car gondolas (2) which are connected via a gondola support device (4) and a cable guide (6) to a haul rope (8) and a track rope (10) of a gondola cableway, with a safety rope (12) which is firmly connected to the haul rope (8) by means of a safety rope guide (14) and to a winch (16) on the cable car gondola (2), and a decoupling device (18) between the cable guide (6) and the gondola support device (4) for separating the gondola support device (2) from the carrying and haul rope (8, 10).

Description

[0001] Many people are afraid to ride in gondolas because they could get stuck for a long time, for example due to a technical defect. To put an end to this fear, we have devised a safety device for cable car gondolas.

[0002] It is therefore an object of the invention to provide a safety device for cable car gondolas that enables the cable car gondolas to be lowered to the ground in an emergency. Furthermore, it is an object of the invention to provide a gondola cable car with cable car gondolas equipped with such a safety device.

[0003] These problems are solved by the features of claim 1 and 8, respectively.

[0004] By providing a safety rope, which is firmly connected to the haul rope and the cable car gondola via a safety rope guide, and a decoupling device to separate the gondola support structure and thus the cable car gondola from the haul rope, the cable car gondola can be lowered to the ground in an emergency using a winch on the cable car gondola.

[0005] According to the advantageous embodiment of the invention according to claim 2, the safety rope guide is also movably connected to the carrying rope, which provides additional safety.

[0006] According to the advantageous embodiment of the invention as described in claims 3 and 4, the decoupling device can be actuated electrically or mechanically. This allows the cable car gondola to be lowered even when no electricity is available.

[0007] According to the advantageous embodiment of the invention as per claim 5, a braking device is provided in the winch to selectively control the descent speed of the cable car gondola in an emergency. This allows the cable car gondola to be lowered to the ground without damage.

[0008] According to the advantageous embodiment of the invention as described in claims 6 and 7, the braking device in the winch can be actuated electrically or mechanically. This allows the cable car gondola to be braked in a controlled manner, even when no electricity is available.

[0009] Further details, features and advantages of the invention will become apparent from the following description of an exemplary embodiment of the invention with reference to the drawing.

[0010] It shows: Fig. 1 a schematic representation of a gondola cable car with a cable car gondola with the safety device according to the invention in operating position between two cable car masts; and Fig. 2. A schematic representation of the cable car gondola being lowered to the ground in an emergency.

[0011] Fig. Figure 1 schematically shows a section of a gondola lift with a gondola 2 positioned between two cable car pylons 3. The gondola is mounted on a haul rope 8 and a track rope 10 by means of a gondola support structure 4 and a rope guide 6. A safety rope 12 is fixed to the haul rope 8 via a safety rope guide 14 and, in normal operation, is wound onto the gondola 2 in a winch 16. For increased safety, the safety rope 12 can also be movably connected to the track rope 10 via the safety rope guide 14.

[0012] A decoupling device 18 is arranged between the cable guide 6 and the gondola support structure 4 in order to decouple the cable car gondola 2 from the cable guide 6 and thus from the haul rope 8 and the track rope 10 in an emergency. As shown in Fig.As shown schematically in Figure 2, in an emergency, the cable car gondola 2 is decoupled from the haul and track ropes 8 and 10 by the decoupling device 18 and lowered to the ground by the winch 16, suspended from the safety rope 12. A braking device (not shown) in the winch 16 ensures that this descent occurs at a low speed, preventing injury to people in the cable car gondola 2. If the power supply is still functioning in the emergency, the braking device is electrically actuated. If the power supply fails, the braking device is actuated mechanically, for example, by a strong spring. The decoupling device 18 can also be actuated either electrically or mechanically.
