ABSTRACT:
A drive element for rail-guided load carriers of an overhead conveyor system in which the driver, which is mounted on the drive element via a hole, has a horizontal groove which extends outward from the hole. Too high a horizontal force acting on the driver causes the drive to be pulled off of the pin. Thus, the drive element which is continuously driven via a drive chain can travel past a conveyor carriage which is blocked in the direction of conveyance without the drive element or the conveyor carriage being destroyed. In order to prevent a driver that has been pulled off of the pin from doing any damage, it is secured via a wire bow which is inserted into a continuous hole provided on the driver. If the overhead conveyor system is developed with branches and a pusher is arranged on the conveyor chain behind each conveyor carriage for pushing the conveyor carriage onto a branch, the pusher claw can be developed in the same way as the driver.
