How the hammer is built
The lower and upper housings are cut from 40–60 mm wear plate, welded by robot, stress relieved and machined on a single CNC set-up so the bushing bores stay concentric.
Hardox-style wear plate, 40–60 mm depending on model, cut on a laser line.
42CrMo forged, quenched and tempered, ground and lapped to the bore.
Integrated bushings with grease grooves; replacement does not need a press shop.
Two-chamber nitrogen accumulator, protected against over-pressure.
40Cr / 42CrMo, forged and heat treated, five profiles from moil to flat.
Grade 12.9 tie rods, torque checked and recorded per unit.
Before it is packed
Each hammer runs on the test bench: oil pressure, impact frequency, leakage check, nitrogen charge and a breaking run under load. The record sheet travels with the machine.
- Pressure hold
- Impact frequency
- External leakage
- Nitrogen charge
- Load breaking run
- Paint and plate check

Packing and loading
Breakers ship in fumigation-treated plywood crates, upright or on their side, with the chisel and the piping kit in a separate box. One 20 ft container takes 4–14 units depending on model; 40 ft HQ takes up to 26.
