The Standard Heavy Duty Pallet Conveyor Platform
The LEWCO CDLR25 is the foundation of LEWCO’s heavy duty chain driven roller conveyor family. Every other model in the 2.5 in. series — the CDDB25 dual chain box, the CDLRW25 wide chain box, the CDLR26 heavy wall, and the CDRC25 curve — builds on the CDLR25’s core specifications. If the application involves moving loaded pallets, drums, or heavy containers on a straight powered roller conveyor, the CDLR25 is the standard starting point.
Positive chain drive through #60 sprockets on every powered roller eliminates the slippage that occurs with friction-based belt driven systems. Each roller turns at the correct speed regardless of load weight, ensuring consistent transport of heavy products across the full length of the conveyor.

Load Capacity
At 60 FPM with 4.5 in. or 6 in. roller centers on a 20 ft. length, the CDLR25 supports loads from 1,050 lbs. (1/2 HP, 60 in. width) to 10,300 lbs. (2 HP, 12 in. width). At 30 FPM, capacity increases to 20,000 lbs. across all widths at 2 HP. Maximum unit load is 1,000 lbs. per linear foot.
Frame Options
The CDLR25 offers four frame configurations to match different installation requirements. The standard frame sets rollers 1/4 in. high in a structural channel with asymmetric side heights. Optional frames include a symmetric 6 in. x 8.2# structural channel with rollers set 1-3/4 in. low, an 8 ga. formed channel bolted frame with rollers high, and an 8 ga. formed channel bolted frame with rollers low. The bolted frame options simplify field assembly where welded structural frames are not required.
The CDLR25 Product Family
The CDLR25 is the base model in a family of related conveyors that share the same 2.5 in. roller platform. When the standard CDLR25 roller centers are too wide for the load footprint, the CDDB25 (dual chain box, 3 in. centers) or CDLRW25 (wide chain box, 3.375 in. centers) provide closer spacing. When the application involves fork truck impact or abusive loading, the CDLR26 upgrades to 7 ga. heavy wall rollers. And when the layout requires curves, the CDRC25 provides chain driven direction changes that match the CDLR25’s roller and drive specifications.
System Integration
The CDLR25 integrates with LEWCO chain transfers, turntables, CDRC25 curves, and the CDTRC tapered roller curve. Extension sections without motors are available for building longer runs powered by a single drive. Quick-ship configurations are available in 43 in. and 51 in. effective widths with 4.5 in. or 6 in. roller centers, shipping in 3–4 weeks.
Applications
The CDLR25 is the standard specification for pallet transport in manufacturing, distribution, and warehousing. Common applications include palletizing and depalletizing lines, loaded pallet transport between production processes, drum and container handling, fork truck load and unload stations, accumulation and staging areas, and integration with chain transfers and turntables for directional routing.
Industries include automotive, appliance, cabinetry and furniture, food and beverage, manufacturing, order fulfillment, and warehousing and distribution.
Selection Assistance from Barron Equipment
Choosing the right CDLR25 configuration — roller centers, frame type, drive location, motor HP, and optional accessories — depends on load weight, pallet type, speed, conveyor length, and system layout.
