Case Study: Enhanced STS Brake System at Shanghai Mingdong Container Terminal
Shanghai Mingdong Container Terminal sought to upgrade the brake systems on its Ship-to-Shore (STS) cranes. The original braking equipment had become outdated, required frequent maintenance, and posed increasing operational risks. To ensure safer, more efficient crane operations, the terminal initiated a retrofit project focused on improving brake reliability and reducing maintenance workload.
Retrofit Solution & Key Benefits
Our team delivered a comprehensive brake system transformation, resulting in more stable, efficient, and environmentally friendly crane operations.
Optimized Performance
- Improved Alignment and Centering: Ensures even wear of components and consistent braking performance.
- Enhanced Braking Efficiency: Provides stronger stopping power and improved operational stability of the cranes.
- Energy Conservation & Environmental Protection: The integration of BUEL H and BUEL G units - featuring biodegradable hydraulic oil - allows the brakes to remain automatically open when idle, reducing energy consumption.
Key Technical Enhancements
- Material Upgrade: New brake arms constructed from durable castings with self-lubricating bushings, eliminating the need for routine lubrication.
- Faster Brake Response: Achieves a rapid reaction time of 200 ms, supporting safer and more precise crane operation.
- Reduced Maintenance Requirements: Increased durability and improved component stability raise overall crane availability and lower maintenance demands.
Results
The completed retrofit effectively replaced an outdated system with a modern, stable, and eco-friendly braking solution. As a result, the cranes at Shanghai Mingdong Container Terminal now operate with significantly improved safety, reliability, and efficiency. The upgraded braking technology also enables operators to reduce maintenance workloads and achieve more consistent long-term performance.
