Small Range - Rammer 555
Rammer 555 rockbreakers have been designed to satisfy the specific demands of rental fleet operators. Weighing 275 kg, Rammer 555, is designed for optimum carrier compatibility and installation flexibility. A flange top-mount for adapter installation, pivoting hose connecting block, reversible manifold, right or left-hand hose connections, and the ability to accept a wide range of oil flows and pressures allow Rammer 555 to work with a broad range of carrier optimum fleet utilisation.
Rammer 555 rockbreakers benefit from 40 percent more power and 20 percent higher blow frequencies than the model it replaces for enhanced power-to-weight ratios and highest possible productivity levels.
