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.
Reversible operation and adjustable belt tension ensure flexibility in system layouts where transfers, side feeds, or accumulation of heavier products are required. The design supports integration with floor supports and industrial control systems for consistent performance in manufacturing and distribution environments.
Applications
- Accumulation and release of cartons and totes
- Zero to low pressure product conveying
- Product routing through curves, spurs, and merges
- Zoned conveying with sensor and control logic
- Unit handling in packaging and assembly lines
- Transfer between processing, sorting, and palletizing areas
Industries
- Distribution and fulfillment centers
- Manufacturing and assembly operations
- Packaging and labeling facilities
- E-commerce order processing
- Consumer goods handling
- Controlled indoor industrial environments
