MTB hydraulic breakers can be used effectively for underwater operations. The pressured air coming from the compressor by a special air pipe inside the breaker is sent between the piston and the tool to push away the water. Therefore it prevents the pressured water from forming to avoid any damage to the breaker and the excavator. We produce 15 different models between 330 - 7150 kg for excavators in the range of 4-100 tonnes.
MTB breakers are manufactured for the toughest excavation work demands rock, concrete, asphalt, marble.
MTB 285 UW breakers which are designed to be used in the underwater breaker series are produced to be 3080 kg for the excavators in the range of 35-45 tonnes. They’re breakers that can be used underwater thanks to their special design.

| (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. |
