Cross Belt Sorters: How to Spec Throughput, Footprint and Parcel Size
Specifying the right cross belt sorter is one of the most critical decisions in logistics automation. A well-specified system delivers years of reliable operation with industry-leading accuracy. A poorly specified one creates bottlenecks, damages parcels, and fails to deliver ROI. This comprehensive guide walks you through the three key parameters you need to evaluate: throughput, footprint, and parcel specifications.
Understanding Throughput Requirements
Throughput — measured in pieces per hour (pcs/h) — is the most fundamental specification for any sorting system. But calculating your actual throughput requirement involves more than just looking at current volumes. You need to consider peak hour volumes rather than daily averages. Most facilities experience 60-70% of daily volume during a 4-6 hour peak window. A facility processing 100,000 parcels daily might need a system capable of 15,000-18,000 pcs/h during peak hours.
Future growth is equally important. MGM recommends sizing your sorter for at least 3-5 years of projected volume growth. Cross belt sorters from MGM's MGMS series range from 8,000 to 22,000 pieces per hour, providing headroom for most operations. The system's modular design also allows phased capacity expansion — you can start with fewer induction stations and add more as volumes grow.
Don't forget to factor in operational hours and maintenance windows. A system designed for 20 hours of daily operation with 4 hours for maintenance will have different requirements than one running 24/7. MGM's cross belt sorters are engineered for continuous operation with remote monitoring that enables predictive maintenance scheduling.
Footprint Considerations
The physical footprint of your sorter is determined by two main factors: configuration type and number of destinations. Cross belt sorters come in two primary configurations — linear and loop. Linear systems are ideal for space-constrained facilities or operations with simpler sorting requirements. They typically occupy less floor space but offer fewer destinations. Loop configurations provide higher density and more destinations in a compact circular footprint.
When evaluating footprint, consider not just the sorter itself but also induction zones, chute areas, and maintenance access. A typical MGM cross belt sorter with 200 destinations requires approximately 800-1,200 square meters of floor space including all peripheral areas. The modular design allows creative layout configurations — L-shapes, U-shapes, and multi-level installations are all possible to maximize your available space.
Minimum turning radius is another critical factor. MGM's cross belt sorters achieve tight turns with a minimum radius of 600mm, allowing dense layouts that maximize sorting capacity per square meter. Our engineering team uses 3D facility scanning and simulation software to optimize the layout for your specific building constraints.
Parcel Size and Weight Specifications
Your parcel profile directly determines which sorter model is appropriate. MGM's cross belt sorters handle parcels ranging from as small as 150×100×10mm to as large as 1200×800×600mm, with weight capacities from 0.1kg to 50kg. However, the full range is rarely needed — most operations benefit from specifying the actual range they handle rather than maximum theoretical limits.
Mixed parcel handling is a key strength of cross belt technology. Unlike tilt tray or narrow belt sorters that may struggle with irregular shapes, cross belt sorters maintain positive control of each item throughout the sorting process. This makes them ideal for courier hubs and e-commerce fulfillment centers that process diverse parcel types.
Special considerations apply for fragile or high-value items. MGM offers soft-start and soft-stop belt control that minimizes acceleration forces, as well as padded chute options for delicate goods. For operations handling a mix of polybags, cartons, and irregular items, the cross belt sorter's versatility is unmatched.
