Low friction carts are grouped or joined by special frames suited to the items being suspended. The cart assemblies run inside a C channel, which is suspended using special hangers on a rigid supporting frame. The channel and support can follow complex closed paths, covering a wide area.
Carts are joined by special chains which provide the traction element for the overhead system.
A special reducer coupled to a sprocket pulls the carts.
The suspended frames can be supplied with electric power through special electric brush carts running inside special power distribution bus bars. |
