Heavy-Duty Powered Roller Conveyor Systems (CDLR)
Excel Conveyors manufactures robust chain driven live roller conveyors (CDLR) engineered for positive traction, heavy industrial load handling, and controlled continuous material transportation across manufacturing, assembly, and foundry floors.
Engineered for High-Tonnage and Positive Drive Routing
Chain Driven Live Roller (CDLR) conveyors are the industry choice for demanding operational spaces where load sizes, weights, or greasy environment factors rule out traditional belt or gravity systems.
Excel Conveyors designs custom powered roller setups specialized for:
- Continuous transport of heavy pallet sets, drums, and casting dies
- High-slip environments involving oily, dirty, or harsh plant conditions
- Reversible operational tracks requiring precise multi-directional control
- Seamless merge loops with automated wrapping and strapping machinery
- Variable index speeds built around precision assembly sequence lines
The CDLR Power Transfer Mechanism
Unlike basic friction or belt-under-roller systems, CDLR conveyors utilize a robust loop-to-loop chain arrangement. Every individual roller is fitted with dual welded sprockets, linking it directly to the adjacent roller.
This mechanism delivers reliable performance advantages:
- Positive traction mechanical engagement with zero operational slippage
- Even torque distribution across long modular layout runs
- Integrated drive motor synchronization for smooth stop-and-go indexing
- Robust component build capable of handling bottom-heavy industrial frames
Built for Tough Industrial Material Handling Applications
Positive Drive Traction
Direct sprocket linkages eliminate slippage, ensuring continuous material movement even when loads are wet or contaminated with oils.
Heavy Weight Capability
Constructed with heavy-walled steel rollers and structural channels to support loads weighing thousands of kilograms without deflection.
Low-Maintenance Bearings
Precision-machined sealed bearings shield internal moving elements from abrasive dust, slag, and industrial debris.
Bi-Directional Flexibility
Mechanical drive designs adapt seamlessly to forward and reverse operation, making them perfect for staging areas and workstations.
Modular Layout Matching
Integrates easily with cross transfers, turntables, and lifters to form highly automated material routing loops.
Safe Smart-Zone Controls
Can be integrated with tracking sensors and variable frequency drives (VFD) for automated zero-pressure accumulation profiles.
Powered Roller Configurations
Technical configurations designed to fit individual speed, weight, and layout footprint criteria.

CDLR Design Considerations
Selection Dependencies:
- Load Characteristics: Footprint size, material type, and base texture set roller centers and diameters.
- Total Weight Mass: Defines roller wall thickness, shaft selection, and chain pitch parameters.
- Speed & Indexing Profiles: Determines gear motor reduction ratios and VFD electronic choices.
- Floor Environment: High heat, chemical oils, or abrasive dust demand specific finishes and sealed bearings.
Targeted Performance Yields:
- Zero Slip Tracking: Eliminates processing delays caused by friction loss or belt wear.
- Controlled Mass Decay: Smooth deceleration curves protect structural frames from heavy impacts.
- Operational Safety: Guarded chain casings enclose moving drives to minimize operator risk.
- Long Installation Life: Rugged design maintains alignment and lowers downtime costs over years of service.
