A measuring and/or tracing device is of the kind having a vertical column, a transverse sliding unit secured to the column and movable in a vertical direction, a cross arm held by said unit and movable horizontally, a holder on the end of the said cross arm for a measuring and/or tracing tool, and a counterweight being disposed inside the column so that it can move freely and being attached to the transverse sliding unit by a cable passing over a guide roller at the upper end of the column. The improvement comprises a safety braking device attached to the transverse sliding unit and acting in conjunction with external surfaces of the column, to which braking device the cable is secured, and which in consequence of the cable tension exerted, is held in a disengaged position out of contact with the outer surfaces of the column, but which, when the cable tension falls, drops automatically into the braking position and engages by gripping rollers or balls with the outer surfaces of the column, thereby preventing movement.

A slide bar for guiding the carriage of a measuring or tracing device along a side of a levelling plate. The slide bar includes a guide rail which is divided into a first strip and a second strip having respective guide faces, the first and second strips being connected by a connector capable of acting as a biaxial joint, and the second strip being positionable adjustably with respect to the levelling plate by means of securing devices and distance pieces such that it may be brought exactly into parallelism with a reference line on the levelling plate.
