The Problem:

Our client, Henry Williams, who specialise in the manufacture of control and signalling equipment for railway networks and the highways industry, had won a contract to develop and install LED road studs for use within lane lights for a major suspension bridge based in Cornwall.

Developed from a need to improve traffic management to The Tamar Bridge in Saltash, the purpose of the LED lane lights was to re-direct traffic to less busy booths to minimise delays. At this time, our client had no manufacturing data available and they were working to within strict time constraints due to the installation of a new toll booth plaza suite.

The Solution

GSPK Design worked closely with the Henry Williams team to reverse engineer and develop the existing printed circuit boards (PCB) supplied by the client and re-design a unit comprising of a back plane PCB, a control PCB, a driver board PCB and LED boards, which were then placed within the designated road studs. The re-designed PCBs were then fitted into a 19 inch rack system set within the client’s own road side control box.

The Result

The client was able to complete the final assembly and installation of the units to the bridge, which are now fully operational thanks to GSPK Design having successfully completed the re-engineering and manufacturing of the units within record time.
