1250T Ship Unloader Electrical Control Retrofit
Electrical control renewal, drive upgrade, signal acquisition, communication and HMI upgrade for a power plant fuel wharf ship unloader.

Background and pain points
A power plant ship unloader undertook coal receiving work at the fuel wharf. After years of service, the original equipment had aging electrical control hardware, aging trailing cables, insufficient system fault tolerance and frequent faults, affecting receiving efficiency and safe production.
- Aging control hardware and trailing cable system
- Insufficient fault tolerance and frequent operating faults
- Declining operating efficiency under heavy-load unloading conditions
Solution, execution and results
Meshox solution
Meshox delivered an integrated electrical control retrofit covering control architecture, hardware integration, control software, site installation, linked commissioning, acceptance and technical training.
Implementation process
- 01Site survey and equipment status assessment
- 02Control design, hardware integration and software development
- 03Installation, linked commissioning and load trial
- 04Acceptance, training and maintenance handover
Results
- Improved equipment operating stability
- Improved control response and operating visibility
- Improved maintainability and documentation
This project shows Meshox can deliver full-loop retrofit work for large, high-load port machinery where acceptance depends on stable operation under real production conditions.
FAQ
Can a similar project be adapted to our site?
Yes. Meshox starts with site survey, equipment status review and operating goals, then prepares a retrofit or integration plan matched to the existing system.
Have a control system, retrofit or integration project?
Start with a project evaluation. An engineer will review your requirements and propose a fitting control solution.
