GB crushers and pulverizers.
Ten rotating attachments across two ranges, for carriers from 4.5 tonne to 48 tonne. The GBMP crusher takes the structure down. The GBPC pulverizer reduces what is left and frees the rebar. Both rotate 360° as standard. Concrete crushers and pulverisers — or pulverizers, as the GB catalogue spells it — for primary breaking and secondary reduction.
CRUSHER
GBMP — primary crusher.
Five models. Big jaw, high cylinder pressure, built for taking concrete structure apart rather than tidying it up afterwards.
GBMP crusher — full range
| Model | Carrier weight | Weight | Max jaw opening | Oil flow cyl. / motor | Cylinder pressure |
|---|---|---|---|---|---|
| GBMP050C | 4.5 – 8 t | 0.62 t | 310 mm | 90 / 15 l/min | 300 bar |
| GBMP160C | 12 – 18 t | 1.1 t | 780 mm | 150 / 30 l/min | 320 bar |
| GBMP200C | 19 – 26 t | 2.1 t | 980 mm | 200 / 30 l/min | 350 bar |
| GBMP300C | 27 – 36 t | 2.8 t | 1,100 mm | 250 / 30 l/min | 350 bar |
| GBMP450C | 37 – 48 t | 4.2 t | 1,250 mm | 300 / 30 l/min | 350 bar |
Rotating motor pressure is 80 bar on the GBMP050C, 120 bar on the GBMP200C and 150 bar on the rest. Figures are General Breaker’s own and are subject to change as they improve the product.
PULVERIZER
GBPC — secondary pulverizer.
Five models, every one carrying the R suffix — hydraulic rotation as standard rather than an option, which matters more on a pulverizer than on almost any other attachment.
GBPC pulverizer — full range
| Model | Carrier weight | Weight | Max jaw opening | Oil flow cyl. / motor | Cylinder pressure |
|---|---|---|---|---|---|
| GBPC05R | 4.5 – 8 t | 0.55 t | 508 mm | 90 / 15 l/min | 300 bar |
| GBPC160R | 12 – 18 t | 1.4 t | 730 mm | 150 / 30 l/min | 320 bar |
| GBPC200R | 19 – 26 t | 2.1 t | 820 mm | 200 / 30 l/min | 350 bar |
| GBPC300R | 27 – 36 t | 3.3 t | 1,000 mm | 250 / 30 l/min | 350 bar |
| GBPC450R | 37 – 48 t | 4.2 t | 1,100 mm | 300 / 30 l/min | 350 bar |
Rotating motor runs at 80 bar on the GBPC05R and 150 bar on the rest.
WHICH ONE
Read the jaw opening, not just the weight.
The number that decides whether one of these suits your job is the maximum jaw opening, not the carrier range. A 730 mm jaw will not take a 900 mm beam however good the machine under it is — and a jaw that cannot close on the section does nothing at all.
Rough rule: if you are demolishing, start at the crusher. If you are processing arisings, sorting rebar out of broken slab or squaring off what the crusher left, start at the pulverizer. Plenty of jobs want both, and the same carrier will usually run either.
Tell us what you are reducing and we will work back from the section size to the model, then check it against your carrier.
THE REST OF THE RANGE
Everything else General Breaker builds.
We are Ireland’s only source for General Breaker — thirty-six hydraulic breakers from 0.8 to 150 tonne, plus grapples, vibro equipment and compactors.

Tell us the carrier and the job.
We’ll tell you the right tool.
Tell us the carrier, the material and roughly how much of it there is. We’ll tell you which model suits the machine and the job, and what it costs.
