FLENDER Gear Units for Ropeways

Description

Ropeways are used not only to carry people but also to transport materials. Various ropeway systems are used in practice. Continuous monocable ropeways are often found in ski resorts as chair lifts or gondolas, for instance.

The gear units in this kind of application obviously have to comply with a number of special requirements: all passenger conveyance systems are subject to very strict safety criteria. The units are exposed to significant variations in temperature and operate almost continuously from the minute they are put into service. For this reason, FLENDER gear units for ropeways are not only compact but also noise- and weight-optimized. They are made with geared parts of the highest quality and extra-strong sealing elements. The fluctuating radial and axial loads on the extremely heavy ropeways, which are frequently several miles long, are absorbed by specially reinforced input shaft bearings. FLENDER gear units and services are available worldwide.
