Used to detect irregularities in road surfaces, both in bituminous compounds and concretes. The equipment is made up of a beam with wheels on the ends and centre. The middle wheels detect any vertical deviation over the hypothetical straight line between the wheels on the ends. The vertical deviations are transmitted from the mobile centre wheel to one end with a scale visible to the operator. Supplied complete with a spray to mark the defective parts of the road.
