Heavy Duty Chain Driven Live Roller Curve Conveyor, Roach Model 251CDLRC

Roach Model 251CDLRC Heavy Duty Chain Driven Live Roller Curve can transport heavy unit loads that do not require product orientation.

TYPE: Chain Driven Live Roller CDLR Conveyors


The Model 251CDLRC is a curved chain driven live roller curve conveyor (CDLRC) designed to transport heavy duty loads such as heavy castings, drums and items not requiring product orientation.


  • Chain driven live roller (CDLR) conveyors, or pallet conveyors, are typically used to transport heavier loads at controlled speeds. Chains drive the sprockets on the load rollers, which in turn drive the chain and the sprocket on the next roller
  • CDLR conveyors transmit the same amount of power to each roller ensuring smooth, even transportation
  • They are well suited for dirty or oily environments, where other types of live roller conveyors do not perform well
  • Curved CDLR’s are used in warehouse operations that handle steel sheet products or structural shapes as well as pallets or skids
  • Designed for torque not speed, these conveyor types transport loads at relatively slow speeds ranging between 35 and 60 feet per minute
  • Model 251CDLRC is reversible. 


  • Transport of heavy unit loads that do not require product orientation
  • Heavy castings, drums, containers, tires, tote pans, & pallet loads may be effectively conveyed on this conveyor
  • Well suited for dirty or oily environments, where other types of live roller conveyors do not perform well
