Chain Driven Live Roller Conveyor (CDLR)

Chain Driven Live Roller Conveyor

Chain-driven roller conveyor systems (CDLR) are sometimes referred to as pallet roller conveyor systems because they are used for pallets as well as wheels, tires, and other products that have a smooth surface underneath.

Single-Stand or Roll-to-Roll (progressive) configurations?

The single-core type is recommended for medium to heavy duty. This type is driven by a continuous chain traveling on sprockets welded to each carrier roller. To ensure that the chain always engages the sprocket, a continuous pressure rod is integrated with the chain guard.
If your conveyor requires frequent starts and stops or reverse operation, a progressive (roll-roller) chain-driven roller conveyor is the best choice. The rollers are progressively driven by loops of chain from one roller to the next. Two sprockets are welded to each roller: one sprocket receives power from the previous roller, and the other sprocket transfers that power to the next roller. Roll-to-roll CDLR conveyors can handle the heaviest loads.

Which type is appropriate for you?

There are two big types of chain-driven live roller conveyors: straight and curved.

Roach 192 CDLRC is a medium-duty chain-driven live roller curve, designed to transport medium-duty loads such as castings or drums. If you need the straight model 192 look at CDLR 192CDLR , a medium-duty chain-driven live roller conveyor. Optional equipment is available. The speed is constant at 1.5-100 FPM; DC variable speed; AC inverter variable speed. Note that the capacity changes with speed 100 FPM max with roll-to-roll chain drive.

When conveying medium-duty pallet loads, use model 254TCDLRC to maintain product orientation.

351TCDLRC is a true taper heavy duty chain driven live roller curve. Ideal for conveying pallets or other heavy unit loads, this conveyor features a “true taper” to maintain product orientation throughout the curve. Here is a heavy-duty 11 ga. tapered rollers, model 351T with sprockets, for true taper effect.

Model 251 is also presented in straight and curved variations. Model 251CDLRC, a heavy-duty chain-driven live roller curve. Heavy castings, drums and other loads not requiring product orientation may be effectively conveyed on this conveyor. Speed is 35 FPM, constant. It is especially suited for carrying loads in the presence of oil and other such contaminants. The chain drive is enclosed, top and bottom, along the entire length of the conveyor. The drive is located on the outside of the curve.

Model 251CDLR is a heavy-duty chain-driven live roller conveyor, specifically designed to transport heavy loads. The model has a roll-to-roll chain drive, minimum overall conveyor length with drive 5′-3″, and maximum overall conveyor length: 58′-6″. Roller bearings of the model 251CDLR provide a roller capacity of 540 lbs. per roller (maximum).

Roach model 3530CDLR is ideal for transporting very heavy unit loads. This heavy-duty chain-driven live roller is designed with heavy .300 wall steel rollers, larger-sized roller chains, and heavy-duty structural frames and supports for applications demanding ultra-durable construction for longevity and durability. Roller capacity is 2500 lbs. per roller. The bed lengths (7-1/2″ RC, #80 CHAIN): Minimum overall conveyor length with drive 5′-0″. Maximum overall conveyor length 80′-0″.
