Teufelberger: The never-ending rope – splicing makes it happen
State-of-the-art ropeways, especially reversible aerial ropeways and tricable ropeways, use two types of rope. On the one hand, tensioned fixed carrying ropes such as TEUFELBERGER's STRESSLESS, which, thanks to several layers of Z-profile wires, have a round, smooth surface. On the other hand, every ropeway also needs a hauling rope to move the gondolas. These ropes such as TEUFELBERGER's SOLITEC® are connected into an endless loop by means of splicing. Now, how is splicing carried out?
TEUFELBERGER's rope installation team has years of experience in installing and splicing ropeway ropes. Also, it conducts regular splice training and tests in order to develop and fine-tune its splicing skills and techniques. The following video explains the splicing procedure in great detail. Making a rope splice, that is, a connection between two rope ends with a continuous transition from one tail end of the rope to the other, is a highly complex matter. For this task, each of the two tail ends of the rope are opened for half the splice length and mutually inserted into one another. In the region of the splice, these inserted tail ends replace the normal rope core, e.g., the fiber core of TEUFELBERGER's SOLITEC® ropes. To prevent the surrounding strands from contacting each other and forming a load-bearing bulge, the inserted tail ends are wrapped. In this case, the quality and thickness of such wrapping are crucial for the quality of the splice. While many other manufacturers use rubber bands for wrapping, TEUFELBERGER relies on a different approach and uses in-house-produced high-strength PP ropes, as they offer far greater wear resistance than rubber. From tensioning of the ropes to the completed splice, making a splice takes about 1.5 days and is a physically challenging task. In addition to the primarily responsible splicer, 5-10 helpers are also needed for the splicing procedure.
TEUFELBERGER's rope installation team is very familiar with the high demands of making splices in Alpine locations. This guarantees that our customers get first-class service ensuring improved rope lifetimes, longer maintenance intervals, and thus lower operating costs. In addition to splicing, rope hoisting, socketing, and the installation of hauling, carrying, or tensioning ropes, TEUFELBERGER also provides support for rope transports.
