Recently, Gree Electric Appliances, a leading home appliance giant, has partnered with  LOGIANT to deploy a customized outdoor autonomous tractor solution at its Hefei production base, enabling cross-zone logistics connectivity across three workshops. Leveraging robust technology, the project has overcome an industry-wide challenge: a 15° ramp on the connecting corridor, opening up material circulation channels between multiple workshops and fundamentally transforming the labor-intensive traditional manual handling model.

Gree Electric Appliances is a world-renowned manufacturer of air conditioners and home appliances. Listed on the Shenzhen Stock Exchange in 1996 (Stock Code: 000651), its main product portfolio covers air conditioners, refrigerators, washing machines, water heaters and other home appliances, as well as new energy equipment and intelligent equipment. It operates 77 production bases worldwide, with products sold to more than 190 countries and regions.

Project Background

This project is implemented at Gree Electric’s Hefei production base. Prior to the upgrade, the base adopted conventional manual logistics operations. The production workflow features numerous process nodes and complex cross-workshop transfer routes. Materials need to be delivered and transported from the central warehouse across three production workshops. The 15° ramp on the connecting corridor, a mandatory passage, represented the biggest on-site operational challenge. Serving as a critical link between the warehouse and multiple workshops, this ramp posed great difficulties for traditional manual trolleys: heavy manual pushing was required for uphill travel, while precise speed control was hard to achieve downhill. Cargo slippage, sideslip, tipping and material damage frequently occurred, forming a major bottleneck for cross-workshop logistics.

Solution

 LOGIANT’ outdoor autonomous tractor travels uphill and downhill smoothly at a constant speed, eliminating the hardship of long-distance, ramp-intensive manual handling. The autonomous tractor can automatically align precisely with the 1-to-3 trailer combination, connect the towing hitch, and lock securely. No manual intervention is needed for hitching or unhitching throughout the process.

Powered by a mixed-traffic scheduling system, multiple outdoor autonomous tractors are coordinated under global scheduling. Connected to the customer’s upper-level system, the system receives production transfer orders and automatically carries out intelligent task decomposition, dynamic global route allocation, ramp passage sequence scheduling, and equipment start-stop control. It delivers fully automated workflows covering warehouse outbound, automatic trailer hitching, long-distance transportation across three workshops via the ramp, and automatic pinpoint stopping.
