Loading-dock safety interlock system

A PLC-based safety interlock coordinates loading-dock gates with vehicle movements to reduce the risk of unsafe operation.

WYE supplied and installed a new loading-dock safety interlock. Vehicle feedback signals were integrated with the existing control circuit so that the protection gate can open only when the correct safe conditions are met, reducing the risk of operator error.

The work included following.

• Safety system design: introduce the safety program to PLC control, the gate only able to open at correct and safe condition. Maximize reduce potential risk causing by human error.
• Add-on ability: not require replace or redesign entire control system, WYE designer can develop add-on system base on original system.
• Complete service: WYE can finish entire work from design, supply to install, testing and commissioning. Avoid client need to encounter project management work at multiple company.

Result

38 interlocking safety device is fully operational and already at the service.
