The winch plays the leading role in cable pulling. However, it is primarily thanks to the cable-laying rollers that the cable reaches its destination safely, without damaging the material and efficiently. As indispensable supporting players, they ensure that the pulling force reaches exactly where it is needed.

During cable pulling, enormous forces act on the entire rig and, above all, on the cable itself. Industry experts know the stresses to which even power cables with conductor cross-sections of up to 2,500 mm² and more are subjected. To the layman, these cables appear almost indestructible. In fact, tensile forces of several tonnes can push cables and machinery to their limits. This makes it all the more important to plan the cable pull carefully and to use the appropriate equipment.

One of the biggest challenges when pulling cables is friction. As we all remember from physics lessons, friction means that considerably more force is required to move an object from A to B. If cables were pulled through a pipe without the appropriate tools, the project would be over in no time, but the actual objective would not be achieved.

For this reason, at least one suitable lubricant should be used when pulling cables with winches. However, as the cable drum can only very rarely be positioned directly at the pipe inlet, it is important to fit the route between the cable drum and the pipe inlet with the appropriate cable guidance systems.

There are a wide variety of solutions for this. They all have one thing in common: a well-planned installation makes cable pulling easier, allows for longer pulling distances and protects the material. They also prevent the steel wire rope and cable from sagging to the ground as soon as the pulling force subsides.

Not every cable pull requires the same cable-guiding systems. That is why there are different models of cable-laying rollers. These are usually made of aluminium or steel, but are also available in plastic versions.
