Rammer 3288 PRO

The Rammer 3288 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 2,240kg Rammer 3288 PRO is suitable for carriers in the 28 to 45 tonne range.
