Specification: The 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 in the 0-10 mm range and 5 mm increments in the 10-25 mm range. It comprises a manual dye marker which is used to mark irregular surface sections when found.

Ltekonline are the manufacturers of Travelling Beam Device used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Bitumen Asphalt Testing Lab Equipment for Engineering Teaching Lab in Universities
