Abstract
The overhead conveyor comprises a main track and a branch track connected to the main track in a switch point, the tracks having a shape of a box-like beam with a longitudinal slit in its bottom flange for suspending a trolley carriage, the carriage supporting a rocking lever having at its ends guiding rollers, the operation of the switch point being safeguarded via tiltable tongues arranged on the lower flange of the track and cooperating with slide shoes provided on the ends of the rocking lever, and by means of locking rails attached to the side walls of the track to lock the rocking lever in the desired angular position; the ends of the rocking lever further support safety noses each having an inclined surface of a length sufficient for bridging the gap between the ends of the inclined tongues and the beginning of the locking rail when the slide shoe still engages the end portion of the safety tong.
