High flange extension beyond the roller lining and maximum groove depth guarantee the highest level of deropement protection. The biaxial setting of the roller batteries ensures their optimal integration into the axis of the rope. Thanks to the high roller pressure of the LEITNER roller batteries, the number of rollers can be reduced, which consequently saves maintenance and spare parts costs. The rubber mixture of the LEITNER rollers results in minimal flexing and therefore in a considerable reduction of the required drive power of the installation.
