Abstract: An apron weigh feeder for use in the heavy bulk materials industry includes a feeder frame, a head drive shaft, a pair of tail traction wheels, and a plurality of carry and return rollers. A pair of drive sprockets is mounted on the head drive shaft. The tail traction wheels are aligned with the drive sprockets, respectively. A pair of endless crawler chains is reeved about the drive sprockets and tail traction wheels, respectively. A plurality of flights is fixed to the crawler chains to define a carrying surface of the apron weigh feeder. The carry rollers support the crawler chains and carrying surface. The carry rollers are supported rotatably by a plurality of carry roller support frames, which are mounted on the feeder frame. The weigh scale assembly is substituted in place of at least one of the carry roller support frames.
