Rammer 2577 PRO
The Rammer 2577 PRO has a sturdy housing design and wear resistant wear plates making it perfect for horizontal working duties in applications such as tunneling.
Hydraulic hose connections for grease, air and water on a top cover plate have been sealed through apertures to withstand extreme working conditions and sealed housing structure prevents the ingress of dust and dirt ensuring extended working life of both the breaker and the tool.
This 1,660kg Rammer 2577 PRO is suitable for carriers in the 23 to 34 tonne range.
