This project involves a new-type petrochemical base with an annual output of 40 million tons for a large oil refining enterprise in Zhoushan, Zhejiang Province, which is building a smart port. Due to the low efficiency and increased labor costs of traditional manual operation modes, they requested Weihua to provide a quotation for automated rail-mounted container cranes for an unmanned container yard.

Customer Requirements

  • Achieve 7×24 hour unmanned operation of the container yard.
  • Lifting capacity of 41 tons, requiring precise positioning and safe lifting.
  • Establish an intelligent management system to achieve visualized monitoring of the entire operation process.

Weihua Solution

In response to the above requirements, the Weihua technical team conducted a field survey, carried out solution deployment and simulator demonstrations, and ultimately customized the design of 6 remote automated rail-mounted container cranes (RACC) for the project. The remote automated rail-mounted gantry crane (RMG) has the following main features:

  • Dual Positioning System: Laser + encoder redundant detection with positioning accuracy of ±5mm.
  • Panoramic Monitoring System: Each unit is equipped with 24-channel high-definition cameras, covering areas such as the crane runway, containers, and vehicle lanes.
  • Intelligent Control System: Integrates automatic anti-sway, container scanning and identification, and one-button automated operation functions.
  • Remote Monitoring Platform: Real-time display of equipment status with 3D simulation. Supports multi-machine collaborative scheduling operations.

Project Results

Currently, the smart port has achieved fully unattended operations while significantly improving container turnover efficiency. The automated rail-mounted container cranes are seamlessly connected to the port TOS system, enabling traceability of the entire process operation data. The successful implementation of this project provides a benchmark case for automated smart port projects, and it is expected that more smart ports will adopt automated rail-mounted crane solutions in the future.
