Belt Driven Live Roller conveyors, identified by Roach Conveyors as CALR (Cam Adjusted Live Roller), are used for controlled transport of cartons, totes, and unit loads where accumulation, zoning, and product handling accuracy are required. Power is transmitted from a continuous belt to individual rollers, allowing conveyed product to move while maintaining consistent roller engagement across the conveyor length. CALR systems are commonly applied in distribution, manufacturing, and packaging operations where product orientation and spacing matter.
CALR conveyors are manufactured using either V-belt or flat belt drive configurations. V-belt driven live roller conveyors are typically limited to shorter runs and lighter loads and are frequently used in tapered roller curves due to their ability to maintain positive roller contact. Flat belt driven live roller conveyors support longer conveyor lengths and higher loads, with overall capacity governed by belt working strength and available belt width. When belt width or layout constraints exist, systems may be segmented into multiple driven sections.
These conveyors support modular system design and integrate easily with curves, spurs, merges, and elevation changes. Cam adjustment allows fine tuning of belt tension and roller engagement, supporting consistent performance across a wide range of applications. CALR systems are well suited for accumulation, sortation, and product routing in both manual and automated material handling environments.
638CALR | Light Duty Belt Driven Live Roller
The 638CALR is a light duty cam adjusted live roller conveyor providing horizontal conveying with the ability to adjust pressure roller engagement quickly via a cam mechanism. It is designed for horizontal transport where side loading, unloading, transfer, or temporary holding of items is required.
138LRC | Light Duty Belt Driven Live Roller Curve
The 138LRC is a light duty belt driven live roller curve conveyor engineered to maintain product orientation through turns using tapered rollers. Its design supports reversible operation and is commonly configured as a driven curve in light duty conveying systems where changes in direction are required.
138LRCS | Light Duty Belt Driven Live Roller Spur
The 138LRCS is a variation of the 138 series configured as a spur conveyor curve for diverting or merging product flow in light duty systems. It uses tapered rollers and belt drive pressure to maintain consistent orientation and motion through the spur section.
196LRC | Medium Duty Belt Driven Live Roller Curve
The 196LRC medium duty belt driven live roller curve integrates tapered rollers with adjustable belt tensioning to preserve product alignment through curved sections. It is reversible and frequently employed as a driven curve within medium duty live roller systems.
196LRCS | Medium Duty Belt Driven Live Roller Curve Spur
The 196LRCS offers a medium duty spur curve solution for diverting or merging product in live roller systems. With tapered roller sections and adjustable belt tension sheaves, it maintains orientation in branching applications and integrates with other medium duty conveyors.
796CALR | Medium Duty Cam Adjusted Live Roller
The 796CALR is a medium duty cam adjusted live roller conveyor that balances load capacity with adjustable engagement. The integrated cam mechanism enables rapid adjustment of roller pressure to accommodate variations in conveyed product weight or spacing requirements.
251CALR | Heavy Duty Cam Adjusted Live Roller
The 251CALR is a heavy duty cam adjusted live roller conveyor built for substantial unit loads and rigorous horizontal conveying demands. Featuring a robust formed steel frame, heavy gauge rollers, and belt driven cam adjusted pressure rollers, this model delivers controlled movement for higher mass applications.
