device for the continuous monitoring of the grounding of an electric public planning transportfahrzeuges tyre

摘要

The device has two sets of shoe pairs ensuring friction or slip on a metal guide rail associated to a whole of auto guidance by rollers rolling on the rail. The shoes and the rail form an electric circuit containing a detector constituting a safety loop sustained/fed by a generator of low tension. The loop is traversed by a current when the contacts of setting to the ground by the shoes and guide rail are correct.
