Travelling Beam Device with Autographic Recorder Supplied Without Recorder Charts.
The 3 metres long Travelling Beam Device is used to check for any irregularities in both concrete and bituminous road surfaces. A sensing unit comprising a wheel connected to an indicator provides a magnification of 4:1.
Deviation of the surface from a straight-line is shown on a scale calibrated in increments of 2 mm up to 10 mm and 5 mm up to 25 mm. A dye-marker is fitted which may be used to identify suspect areas. Outrigger wheels provide mobility on site. The device is supplied as three sub-assemblies which are quickly assembled on site. The Travelling Beam is supplied fitted with an autographic recorder providing a permanent record of the surface profile. Records up to 1 kilometer can be recorded on the special chart paper rolls used.
Product Features

• Beam length: 3 m.
• Scale: 2 mm increments up to 10 mm; 5 mm increments from 10 to 25 mm.
• Max vertical deviation: ± 25 mm.
• Weight approx.: 55 kg.
