New two-speed hydraulic breaker for heavy carriers
Montabert, leaders in hydraulic breaker technology, have launched the new V4500 model, the largest in the company’s range of automatic two-speed breakers. The V4500 hydraulic breaker can be mounted on excavators from 45-tonnes to 80-tonnes. It is designed for high productivity work on homogeneous rock surfaces, including civil engineering applications and secondary breaking in quarries and mines.
In common with all other Montabert breakers, the V4500 model offers superior productivity, reliability and durability, a high power to weight ratio, easy maintenance, a long life span and a high resale value.
The weight of the V4500 breaker with top bracket and tool is 4,500kg. The V4500 works with a maximum input power of 117kW, a hydraulic flow of 380 litres/min, providing a frequency of 750 blows/min at an operating pressure of 185 bar. The V4500 has the advantage of being able to work with high back pressures up to 25 bar and offers true overflow protection as standard. The robust, heavy-duty housing and large retainer pins allow the V4500 to work with large tools with diameters up to 190mm.
The standard version of the V4500 breaker is Metro Silenced, and can be equipped with a pressurization circuit for underwater work and tunnelling.
