Haulage and supporting rope roller set - has support rocker with eye at end to receive end rope which is tensioned by spring

摘要

The set of supporting rollers is for a single haulage and supporting rope for overhead transport, having one or more rocker levers on a central spindle and on each of which two rollers pivot. The rocker spindles are in turn supported by auxiliary rockers or directly from a pylon, portal etc. Each rocker (3, 4, 5) has a guide (23) at each end in the form of an eye. One of the ends of a rope (24), which is passed through all the eyes, is anchored to a fixed point on one of the rockers, the other rope end is anchored to a component movable on another rocker between two end positions. Springs tend to hold this component in an end position corresponding to the increase in rope tension.
