Zip-line

The zip line, also cable car, "Flying Fox " in Switzerland " tyrolean traverse " or " zip line " (as in France ), in Austria " guerrilla slide " (English zip line, ziplining ), a cable connection between the two is located at different heights points for crossing ravines and rivers. For hanging or passengers are transported on a roller or a snap hook.

Ziplines with static rope

For ziplines only tested static ropes may be used with low elongation. See Safety and tensioning the cables in the cable car products.

Safety-related systems are duplicated ( redundant ). Also a static safety rope is used in addition to supporting cable always being curious about one meter above the supporting cable. On two cables running one each rope pulley which are mutually connected via a belt loop and Schraubkarabinern. This special closed double rollers are used. Alternatively, screw-lock can be used. Screwgate be hung with the screwed down ( upside down ) so they can not screw due to vibration. The load or person is suspended by a sling in the lower roller. For passenger transport, the connection of harness and belt loop with two counter- hinged Schraubkarabinern is run. The person may not be able to grab the rope or the role and also serious people must at all times be free from contact with the ground.

Braking is done with a third cable, the brake cable. This is guided over a deflector mounted on the fastening point of a helper. Thus, the pulley, or if difficulties the person who will bring it back.

For anchoring to a tree is said to have a minimum diameter of 20 cm. To fasten the ropes there are two systems:

• A 30 to 50 mm wide strip loop is placed around the tree twice and suspended in the screw-lock loops a
• The rope is repeatedly wrapped around the anchor tree and secured the end to a second tree, on a strong branch or the supporting cable itself. The bark of the trees must be protected.

In a rock bolting each have their own anchorage is needed for each cable fastening. With bolts an axial tensile strength of 1500 daN is achieved. Each end of the rope is a precaution in addition connected to the anchoring of the other rope. The rope is attached to the carabiner and the mountain rescue knots.

The rope is attached to the carabiner with a HMS - node and secured with a slip knot and an overhand knot ( mountain rescue knots). This allows the attachment to be relaxed and released under load at all times and on both sides. The rope is tensioned with a pulley. The deflections are fastened with a belt loop with a cross clamp node ( never with an accessory cord ) and passed over a pulley. After clamping the support cable is attached to the anchor point, for example, wound twice around the tree and secured to a tree branch or the rope itself. The pulley must then be relaxed ( otherwise there is a melt combustion of the sling when it slips even just a few centimeters on the rope ).

Rope slides with steel cable

For a permanent place cableways steel cables are used, for example, cable cars on the high ropes, climbing forest, or in children's playgrounds. When using steel cables ISO standards are taken into account.

Accidents

In 2000, three people died on a zip line through a gorge along the Caminito del Rey.
