tragseile

Tragseile, known in English as support ropes or simply carrying ropes, are a fundamental component in rope-based transportation and securing systems. They form the primary weight-bearing element in various applications, from simple manual hauling to complex engineered structures.

In material transport systems, tragseile are the main ropes along which loads are moved, often via pulleys or carts. This is common in cable cranes used in logging, construction, or mountainous terrain for moving equipment and supplies. A key distinction is that these ropes carry the payload, differentiating them from traction ropes, which provide the motive power to move the load along the carrier rope.

Within the realm of cableways, such as gondola lifts or aerial tramways, the tragseil is the massive, stationary cable that the cabins or chairs travel upon. These ropes are engineered for immense strength and durability, designed to withstand heavy static loads, wind forces, and constant friction from the moving grips of the vehicles.

The term also applies to the main supporting ropes in tents, large awnings, and suspension bridges, where they bear the structural tension. The construction of a tragseil is critical, typically involving high-strength steel wires wound into a strand, with multiple strands then helically laid around a core to create a robust and flexible cable. Their specification depends on the required tensile strength, resistance to abrasion, and environmental conditions, making them a vital element in engineering and logistics.
