A cross belt sorter sorts items on a loop of carriers, each carrying a short powered belt set perpendicular to travel. When a carrier reaches its destination, its belt runs to discharge the item left or right onto a chute. It sorts mixed and fragile goods accurately at rates up to 20,000 items per hour.

Cross belt sorter at a glance

A cross belt sorter, also called a crossbelt sorter, runs a train of carriers around a continuous loop. Each carrier holds its own short belt mounted crosswise to the direction of travel, and when the carrier passes its assigned chute, that belt powers left or right to gently push the item off the loop. Because every item rides its own belt, the sorter handles a wide mix of parcels, polybags, apparel, multimedia, and fragile or bottled product at high accuracy. Interroll cross belt sorters reach throughput up to 20,000 items per hour, handle goods up to 50 kg, and run in horizontal or vertical loops in oval, U, or straight shapes. A single motor and rubber drive belt power the carrier train, so there is no chain to lubricate.

How does a cross belt sorter work?

A cross belt sorter connects many carriers into a train that circulates around a closed loop. Each carrier supports a small belt conveyor oriented across the track. Items are inducted onto the carriers manually or by an automated induction belt, and the controls track each item to its destination. When a carrier reaches the correct chute, a drive engages that carrier's cross belt, which runs sideways to discharge the item to the left or right. On a horizontal loop, an item with no available destination can stay on the loop and recirculate rather than mis-sort, then discharge on the next pass. The carriers run on low-resistance wheels and are driven mechanically by a single high-efficiency motor.

Where are cross belt sorters used?

E-commerce fulfillment. Sorting high volumes of mixed parcels and polybags to many destinations.

Parcel and post. Routing packages and mail to carrier or route chutes at high accuracy.

Apparel and multimedia. Handling flat, soft, and irregular items that diverters struggle with.

Fragile product. Discharging gently with a powered belt rather than a hard push.

Dense chute layouts. Serving many closely spaced destinations around one loop.

What is the difference between a cross belt sorter and a sliding shoe sorter?

Both are high-rate sorters, but they discharge differently. A cross belt sorter carries each item on its own powered belt and runs that belt to discharge, which handles soft, flat, and fragile goods and allows items to recirculate on the loop if a destination is busy. A sliding shoe sorter pushes items across slats with guided shoes, which suits cartons and cases at high speed. Choose cross belt for mixed parcels, apparel, and many destinations on a loop. Choose sliding shoe for case sortation on a straight line. The comparison below frames the choice.
