Three types of live rollers are categorized by their size (wide and length). The live roller 1000x1200 with scale (drawing number PDS.LRC.0401.006.000) has additional load cell. This live roller type can also scale the weight of the product. The liver roller 1000x1350 and liver roller 480x1630 (drawing number PDS.LRC.0401.007.000) has 2 wide-size rollers (1000 wide and 480 wide) connect together. The roll conveyor tunnel (drawing number PDS.RCT.0410.000.000) is one of the conveyor. It has an added on equipment over it. The additional equipment is used to close the lid of the material box.
