ZTO Express Hub: Loop Cross Belt Sorter Processing 500,000+ Parcels Daily

Project Overview

With the rapid growth of e-commerce and express delivery services, logistics hubs are facing increasing pressure to improve parcel processing efficiency, sorting accuracy, and operational flexibility. Traditional manual sorting operations can no longer fully satisfy the requirements of modern express distribution centers, especially during peak seasons when parcel volumes increase significantly.

To support the intelligent upgrade of ZTO Express logistics hub, YJ-INTL provided a customized double layer loop cross belt sorter solution designed for high-volume parcel sorting operations.

The project adopts a true double layer loop cross belt sorting system, featuring 816 sorting chutes, 660 cross belt carriers, 24 induction stations, and 4 induction zones. Through advanced mechanical design, intelligent control technology, and automated sorting processes, the system helps improve sorting efficiency while ensuring stable operation for daily logistics activities.

This project demonstrates YJ-INTL’s expertise in delivering complete logistics automation solutions for express companies and large-scale distribution centers.

Customer Background and Project Requirements

Supporting the Growth of Express Logistics Operations

As one of China's major express delivery companies, ZTO Express operates extensive logistics networks requiring efficient parcel handling capabilities. With increasing parcel volumes driven by e-commerce growth, logistics hubs need automation systems that can process large quantities of parcels accurately and continuously.

The High-Tech logistics center required an advanced sorting solution to overcome several operational challenges:

1. Increasing Parcel Processing Demand

The rapid development of online shopping and regional distribution networks created higher requirements for parcel sorting capacity. The sorting system needed to support multiple destinations while maintaining stable performance.

2. Reducing Manual Sorting Dependency

Traditional manual sorting methods involve high labor requirements and may experience efficiency fluctuations during peak periods. Automation was required to improve operational consistency and reduce dependence on manual processes.

3. Improving Sorting Accuracy

For express logistics operations, accurate destination identification and parcel routing are essential. The system needed to ensure reliable sorting performance while minimizing sorting errors.

4. Optimizing Warehouse Space Utilization

Large logistics hubs require efficient use of available space. A double layer sorting structure provides better vertical space utilization compared with traditional single-level systems.

YJ-INTL Solution: Double Layer Loop Cross Belt Sorter System

Advanced Automated Sorting Technology for Express Hubs

Based on the operational requirements of ZTO Express hub, YJ-INTL designed and delivered a true double layer loop cross belt sorter system.

The system configuration includes:

• Sorter type: True double layer loop cross belt sorter
• Cross belt carriers: 330 × 2 units (660 carriers total)
• Sorting chutes: 408 × 2 units (816 sorting destinations)
• Chute width: 750mm standard configuration
• Curve chute width: 800mm
• Induction stations: 24 units
• Induction zones: 4 zones
• Equipment height: 2.2m / 3.4m
• Operating speed: 2.0–2.5m/s

The above configuration enables the system to efficiently handle complex parcel sorting requirements in modern express distribution environments.

How the Double Layer Loop Cross Belt Sorter Works

The cross belt sorter uses independently controlled carrier units running along a closed-loop track. Each carrier is equipped with a small conveyor belt that can move parcels accurately toward designated destinations.

The automated sorting process includes:

Parcel Induction

Operators or upstream conveyor systems introduce parcels into the sorter through multiple induction stations. The four-zone induction layout improves parcel feeding efficiency and balances system workload.

Automatic Identification

Parcels are identified through integrated scanning and control systems. The system determines the correct sorting destination based on logistics information.

Intelligent Routing

The control system tracks each parcel position and calculates the optimal discharge point.

Accurate Discharge

When the carrier reaches the assigned destination chute, the cross belt automatically moves the parcel sideways into the correct sorting location.

This continuous automated process improves sorting consistency and supports stable logistics operations.
