SZA251CDA
Chain Driven Zero Pressure Accumulator Smart Zone® Heavy Duty Conveyor
The SZA251CDA heavy duty chain driven Smart Zone® accumulator extends the benefits of zero pressure accumulation to heavier unit loads and more demanding conditions. Photoelectric sensors manage zone detection without minimum weight activation, while chain drive mechanics deliver robust traction across broader loads and extended run lengths. This model handles the rigors of heavy duty accumulation where pallets, larger containers, and dense packages must be buffered without back pressure.
Roll-to-roll chain systems combined with precision bearings and enclosed chain guards ensure sustained performance in high usage environments. The zone design allows for precise singulation control, and the conveyor’s construction supports multi-zone layouts that integrate with larger conveying systems common in industrial processing, distribution, and heavy goods handling.
Applications
- Product buffering between processes
- Merging and singulation of cartons or totes
- Accumulation before sortation, labeling, or inspection
- Controlled release into packaging or palletizing equipment
- Staging product for shipping and order fulfillment
Industries
- Distribution and fulfillment operations
- Manufacturing and assembly lines
- Packaging and material handling systems
- Food and beverage processing
- Automotive and industrial manufacturing
