Wire Wizard at work

10 Aug 2010

GERMANY: The OVHWizard from Dr D Wehrhahn Messsysteme für die Qualitätssicherung uses ultrasound to measure the height and position of overhead contact wires to help identify wear.

Measuring runs can be evaluated on site or at the office, with data displayed graphically or tablulated. Deutsche Bahn has certified OVHWizard for use on road-rail vehicles, but the battery-powered unit weighs just 4 kg, making it easy to handle and install on almost any rolling stock including trolleys and light rail vehicles.
