GBN series hydraulic breakers
GB’s main run of hydraulic breakers — seventeen models from a 75 kg hammer for a 0.7 tonne mini digger up to a 6.3 tonne unit for a 100 tonne machine. Box-silenced across the range bar the open-frame GBN10T, Hardox bodies, and every wear part on our shelf in Ballyclare. Box-silenced rock breakers — hydraulic hammers in a fully enclosed housing — for everything from a mini digger to the biggest quarry machines.
The best-selling line
Sized across every common carrier.
The GBN is the breaker most GB owners run. A silenced box housing takes the noise and the recoil off the machine, the working end is built in abrasion-resistant steel, and the internals are simple to strip and service. Because we sell them across Ireland, the chisels, bushes, seal kits and wear parts sit on the shelf here rather than on a boat.
Match the hammer to the machine.
Carrier weights are GB’s own figures. If your excavator falls between two models, ring us — the right answer depends on what you are breaking and how long you are at it, not just the weight on the plate.

The detail
Built to work, built to be fixed.
Box-silenced
The enclosed housing cuts noise on site and soaks up recoil before it reaches your boom and arm — easier on the machine and the operator.
Hardox body
Abrasion-resistant steel where the wear happens. The breaker lasts, and the parts that do wear are cheap and on our shelf.
Parts in Ballyclare
