  • the roller battery 2 is an assembly having a plurality of successively arranged rollers 21 for guiding and securing the cable 3.
  • Roller batteries 2 carry the weight of a rope 3 and its hangers (high holder), push a rope 3 down (hold down) or combine these functions (change holder).

  • the roller battery 2 usually has a battery structure and pulleys or rollers 21, wherein the rollers 21 in the
  • Battery structure are rotatably mounted, so that the cable 3 is guided on the rollers 21 of the roller battery 2.

  • Roll battery is impossible by a person on site.
  • the maintenance of such a roller battery 2 includes the removal of all axes of rotation, their cleaning and testing and reinstalling the axes of rotation.

  • This requires in addition to the high cost of transporting the roller battery several hours of preparation for each pillar.
  • the current solution of the prior art for the maintenance of the roller batteries is therefore complicated and unsatisfactory.

This has the advantage that the work platform can be large enough for the necessary maintenance work and still hangs stable on the rope. This embodiment is particularly advantageous in combination with the two lifting mechanisms, as this allows the height difference of the rope at the two attachment points with the two lifting mechanisms can be compensated.
