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 705 UW breakers which are designed to be used in the underwater breaker series are produced to be 7150 kg. for the excavators in the range of 65-100 tonnes. They’re breakers with special design which can be used on docks and under the sea.
