About this family

There are two versions: GRB-MIKRO, the standard grading beam, and GRBH-MIKRO, the hydraulic grading beam. Both come in 1500, 1800 and 2000 mm widths and are 346 mm long and 267 mm high. GRB-MIKRO weighs 86, 100 or 113 kg and GRBH-MIKRO 113, 128 or 141 kg, depending on width.

A grading beam is wide and flat, so you get a large working width and you see the edge.
