Overview
A Port in Qingdao China needed to install cameras on container crane spreaders to ensure front-end visualized operations. However, due to the limitations of the crane slip ring design, it was not possible to deploy additional Ethernet cabling.
To achieve network communication at minimal cost, the customer sought a solution that could reuse the existing wiring. Through an industry introduction, they learned about Ourten’s Ethernet Extender solution and decided to conduct tests, finding it to be a perfect fit.
The customer faced several concerns when evaluating options:
Unstable wiring under heavy motion – The crane operates with constant movement and rotation, causing excessive strain and reduced cable durability.
Severe on-site electromagnetic interference – Wireless transmission solutions were tested but resulted in poor and unreliable image quality.
Costly new cabling – Re-laying Ethernet cables disrupted equipment usage, required periodic replacement, and significantly increased maintenance costs.
By testing and evaluating Ourten's 4-Ch Din-rail Ethernet Extender OT-PLC604-TL, the customer identified clear advantages for port crane applications:
Reuse of existing 2-wire cabling – No need for additional Ethernet deployment.
Strong anti-interference performance – Certified to EFT Surge Immunity Class A, fully ensuring reliable operation in harsh port environments.
Plug-and-play design – Zero configuration, no debugging, and minimal maintenance required.
With Ourten's 4-Ch Din-rail Ethernet Extender OT-PLC604-TL, the port achieved:
60% cost reduction compared to traditional rewiring methods.
Stable high-definition video transmission for real-time crane monitoring.
