"power and free" overhead conveyor
Typ 374 - 300 kg / Trolley Hero-Fördertechnik

The special Hero-rail elements enable variable arrangement of the line, to turn the conveying direction in horizontal and also in vertical way, up to running straight vertical. The vehicles generally carry a special designed hanger matching the load requirements. The track segments are usually supported by special designed steel structure hanging at roof construction or standing on floor.

We basically divert into Power Rail that is to take up the chain trolleys and the Free Rail that is to take up the load trolley. Both, the Power and the Free-rail, is connected via special sheets.

The Power-chain is attached with chain dogs (in pitch). These chain dogs catch the trolley dogs of the free-trolleys and so the free trolley will start to move. In Stop stations the free-trolley dogs can be pushed down so unlink the free trolley from the chain-dog. In this way the free-trolley can be stopped while the chain is still moving. The same method is also used to queue trolleys behind each other along a - generally - straight track segment.
