MTB breakers are produced for the toughest excavation demands rock, concrete, asphalt and marble. MR (Marble) serie breakers outer chassis has a completely special design anda re produced with wear-resistant materials. Also our Marble serie breaker’s side surfaces are made as one single piece and without welding. This way the effects of the forces on the side surfaces of the breaker is lowered. We produce 9 different models between 1300-7200 kg for marble quarries and heavy working conditions for the excavators in the range of 25-100 tonnes.
MTB 505 MR breakers which are designed to be used in the Marble series is produced as 4750 kg for the excavators in the range of 50-65 tonnes. They are also used as rock breakers for rock quarries.

| (a) It includes the approximate weight of the breaker, bracket, standard tool and hose weights. Total operational weight could vary depending on the model of the carrier machine. |
| (b) Actual impact frequency depends on the oil flow, oil viscosity, temperature and the material to be broken. |
| (c) Actual pressure depends on the oil flow, oil viscosity, temperature, material to be broken and the return pressure. |
| (d) Input power directly effects fuel consumption. Low input power (kW) requirement means low fuel consumption. |
| (e) Guaranteed sound power testing results according to directive 2000/14/EC (Guaranteed dB(A)=Measured Value +3 dB). |
| (f) If the carrier machine is out of the optimum range, ask the carrier machine manufacturer for allowed attachment weight. |
