Rooftop transfer chain is used chiefly in two or more stands on transfer conveyors handling lumber, boxes, packages, barrels, bars, etc. Only the bevel tops of the links project about the guides, permitting loading and unloading to be done transversely.
Industries
Links are cast of high grade malleable iron or Duramal. Duramal is a heat treated copper bearing malleable iron having greater strength and superior resistance to wear and abrasion. Duramal chains have heat treated pins.
Rooftop transfer chains are interchangeable with other standard makes of corresponding sizes and numbers.
Rooftop transfer chain is used chiefly in two or more strands on transfer conveyors handling lumber, boxes, packages, barrels, bars, etc. Only the bevel tops of the links project above the guides, permitting loading and unloading to be done transversely.
Rooftop transfer chains are made to operate in only one direction and therefore are not recommended for installations that require reverse operation. The load carried and frequency of operation determine the speeds, but generally the recommended speed is 100 FPM. Maximum chain speed depends upon size of sprockets. For Conveyor Service see Table 2, Section A.
