A damper is described for cableway traction cables comprising a carrying cable (2) stretched between a downstream station and an upstream station with a traction cable (3) returned by pulleys in the stations and at least one support (9) of the cables (2, 3) provided along the path of the cableway and bearing a support and a roller battery and a plurality of cabins (4) running along the carrying cables (2) and can be coupled with the traction cable (3) by means of clamps (6). In accordance with this invention to the structure of the roller battery and preferably at the entrance of the roller battery in the direction of movement (16) of the cabins there is joined a lever (12) bearing at its free end a roller (13) engaged on the traction cable (3) and the lever is loaded by elastic means or weights towards the traction cable in such a manner as to soften the passage of this roller over the back of the clamp and to accompany the traction cable in the lowering onto the roller battery.

The invention claimed is: 1. A cableway system comprising: a carrying cable extending between a downstream station and an upstream station; a traction cable extending between the downstream station and the upstream station, the traction cable returned by at least two pulleys in the stations; at least one support of the carrying cable and the traction cable provided along a path of a cableway, the at least one support including at least one roller battery; a plurality of cabins running along the carrying cable, said plurality of cabins each coupleable with the traction cable using at least one clamp; and a damper including: (i) a first lever having a first end and a second end, the first end of the first lever joined to the roller battery at an entrance of the roller battery in a direction of movement of the cabins, the second end of the first lever being a free end connected to a roller engageable with the traction cable, the first lever loaded by at least one selected from the group consisting of: an elastic member, a spring, and a weight to bias the roller toward the traction cable to soften a passage of the roller over the at least one clamp and to accompany the traction cable in a lowering onto the roller battery, the first lever dampened by a shock absorber selected from the group consisting of: a pneumatic shock absorber and a hydraulic shook absorber, and (ii) a second lever configured to co-act with the first lever, the second lever including: (a) a first arm having a free end, the first arm joined at said free end to the at least one support, the first arm supported by a compression spring, (b) a second arm having a free end, the second arm including at said free end a guide runnable on the carrying cable, and (c) an elbow fitted with a contrast member configured to shift the first lever depending on the position of the carrying cable, said shift dampening a vibration of the traction cable. 2. The cableway system of claim 1, wherein the guide of the second arm of the second lever includes a grooved roller. 3. The cableway system of claim 1, wherein the contrast member of the second lever includes at least one selected from the group consisting of: a pin and a roller. 4. A cableway traction cable damper comprising: a first lever having a body, said body including: (i) a first end attachable to a roller battery of a support structure, the roller battery configured to support a traction cable extending between a downstream station and an upstream station, the support structure configured to support a carrying cable extending between the downstream station and the upstream station, and (ii) a second, free end; a roller attached to the second, free end of the body of the first lever, said roller engageable with the traction cable; a first biasing member selected from the group consisting of: an elastic member and a weight, said first biasing member configured to co-act with the body of the first lever to bias the roller attached to the second, free end of the body of the first lever toward the traction cable to enable the roller to engage the traction cable to soften passage of the roller over at least one clamp which is attachable to the traction cable; a shock absorber connected to the body of the first lever and connectable to the roller battery, the shock absorber selected from the group consisting of: a pneumatic shock absorber and a hydraulic shock absorber, said shock absorber configured to dampen a movement of the first lever; a second lever having a body, the body including: (i) a first end configured to engage the carrying cable, and (ii) a second end configured to co-act with said first lever; a second biasing member selected from the group consisting of: an elastic member and a weight, said second biasing member configured to bias the first end of the body of the second lever toward the carrying cable to enable the first end of the body of the second lever to engage the carrying cable; and a contrast member configured to co-act with the second lever to enable the second lever to shift a position of the first lever based on a position of the carrying cable. 5. The cableway traction cable damper of claim 4, wherein the first end of the body of the first lever is attachable to the roller battery at an entrance of the roller battery in a direction of movement of the traction cable. 6. The cableway traction cable damper of claim 4, wherein the elastic member includes a spring. 7. The cableway traction cable damper of claim 4, wherein the first biasing member is configured to co-act with the body of the first lever to bias the roller attached to the second, free end of the body of the first lever toward the traction cable to control a movement of the traction cable toward the roller battery. 8. The cableway traction cable damper of claim 4, wherein the contrast member includes at least one selected from the group consisting of: a pin and a roller fitted in an elbow formed by the first end of the second lever and the second end of the second lever. 9. A cableway traction cable damper comprising: a first lever having a body, said body including: (i) a first end attachable to a roller battery of a support structure, the roller battery configured to support a traction cable extending between a downstream station and an upstream station, the support structure configured to support a carrying cable extending between the downstream station and the upstream station, and (ii) a second, free end; a roller attached to the second, free end of the body of the first lever, said roller engageable with the traction cable; a first biasing member selected from the group consisting of: an elastic member and a weight, said first biasing member configured to co-act with the body of the first lever to bias the roller attached to the second, free end of the body of the first lever toward the traction cable to enable the roller to engage the traction cable to soften passage of the roller over at least one clamp which is attachable to the traction cable; a shock absorber connected to the body of the first lever and connectable to the roller battery, the shock absorber selected from the group consisting of: a pneumatic shock absorber and a hydraulic shock absorber, said shock absorber configured to dampen a movement of the first lever; a second lever having a body, the body including: (i)a first end configured to engage the carrying cable, and (ii)a second end configured to co-act with said first lever; a second biasing member configured to bias the first end of the body of the second lever toward the carrying cable to enable the first end of the body of the second lever to engage the carrying cable; and a contrast member configured to co-act with the second lever to enable the second lever to shift a position of the first lever based on a carrying cable position. 10.
