Abstract

According to the invention an arrangement (10) is proposed for measuring and checking motorcycle frames, comprising a measuring beam (14) which is attached to one side of the motorcycle frame which is to be checked, parallel thereto and preferably at the so-called pivot-point of the frame. One or more uprights (16, 18) at right-angles to the beam (14) can be moved along the beam and themselves bear movable mountings (24, 28) with adjustable measuring points (26, 30). The latter can be made to seek out desired points on the frame, and with the aid of appropriate scales or calibrations the co-ordinates of the points relative to the pivot point can be determined. Two such measuring arrangements (10) placed one on each side of the motorcycle frame can be connected together by means of transverse bridges or the like to form a stable measuring stand. The arrangement is such that frame measurements can be carried out whether the frame has been dismantled or forms part of a complete motorcycle, and furthermore measurements can be carried out even if the frame or the motorcycle is set up in a straightening device, so-called traction jig.
