Standard
GRB Grading & levelling beams
The whole range: Excavator tools
Compatible interfaces: S · MS · CW · OQ · M · SW
- 2.5–30 tons
- Carriers: Mini, Midi, Large
The GRB is a grading beam for excavators. It spreads and levels soil, gravel and sand over a wide strip, and it holds a flatter surface than a grading bucket because the long blade and the roller behind it both ride on the ground.
Features
- Three versions: Basic without roller, Standard with roller, hydraulic tilting up to 45 degrees each side
- Two sizes: GRB midi 6 to 18 t in 2000 and 2500 mm, GRB maxi 10 to 30 t in 2500 and 3000 mm
Base features:
- HB500 Wear Bars on bottom
- HB500 Cutting Edge
- Top plate ready for Bolt-On Bracket
- Adjustable Roller
- Roller runs on bearings
- Bearing to roller connection protected against knocks
Optional features:
- Bolt-On Bracket / Adapter
- 250 mm Extendable Side Beams
- Mounting spot for level measuring device
- Hydraulic cylinder guard
- Hardox® wear bars on bottom of beam - option

About this family
Three versions are built. The Basic beam is rigid and runs without a roller. The Standard beam is rigid and carries a roller on bearings; the roller height is adjustable, so you set how much material stays behind the edge. The hydraulic version tilts up to 45 degrees to each side, which lets you pull a slope or a crossfall without moving the machine.
Two sizes. GRB midi fits machines of 6 to 18 t and comes 2000 or 2500 mm wide; GRB maxi fits 10 to 30 t and comes 2500 or 3000 mm wide. Weights run from 216 kg for the Basic midi 2000 to 680 kg for the hydraulic maxi 3000.
The bottom carries HB500 wear bars and the cutting edge is HB500 as well. The top plate is prepared for a bolt-on bracket.
Options: a bolt-on bracket or adapter, side beams that extend by 250 mm, a mounting spot for a level measuring device, and a guard for the hydraulic cylinder. Hardox® wear bars can replace the standard ones.
