Attachment Comparisons
Both are HKM-manufactured hydraulic breakers built to the same quality discipline. The difference lies in the working pattern each is configured around.
Both lines cover a wide band of carriers, and model selection is made first by tonnage, then by flow and pressure.
The choice of line usually relates to working intensity and site conditions; both lines have models in the same tonnage bands.
For the right decision, compare MODELS rather than lines: enter your machine tonnage, flow and pressure in the selector and the models that suit you will be listed from both lines, with their spec differences side by side.
HKM breaker line; includes M models reinforced for mining conditions.
HKM breaker line; structured as mini, medium and heavy classes.
There is no general ranking between the lines; the decision is made at model level. The order below is the right approach.
| Criterion | Red Line | Grey Line |
|---|---|---|
| 1. Carrier tonnage | Mandatory criterion | Mandatory criterion |
| 2. Machine oil flow | Must be in model range | Must be in model range |
| 3. Operating pressure | Must be in model range | Must be in model range |
| 4. Material and working hours | M models for heavy/continuous | Adjusted by class choice |
| 5. Tool type | Chosen by the job | Chosen by the job |
That generalisation is not correct. Both lines have models in different tonnage and power classes; the comparison should be made at model level rather than line level. List the models that suit your machine with the selector and view their spec values side by side.
The M suffix marks models reinforced for mining and quarrying conditions: continuous working, abrasive material and dusty environments.
Both are HKM-manufactured and spare part supply runs through the same channel. The spare part categories contain parts for both lines, and we also make parts compatible with more than 130 breaker brands.
