Rammer 155 is one of the fastest hitting hydraulic hammers. It features in integrated tubular membrane type accumulator which maximizes it's surface area, to deliver the maximum breaking power.
PRS (Pressure release system)
The pressure release system (PRS) allows for the faster and safer removal of hose connections when dismounting.
The twin-handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
- Pin and Flange mounting
Single lower tool bushing
The single lower tool bushing, replaces the need for an upper and lower tool bushing, whilst being field replacable. This makes for faster and easier field service.
Membrane type accumulator
Membrane-type accumulator eliminates nitrogen leakages, ensuring maximum piston acceleration and removing the need for time-consuming recharging.
- Cast Housing
No tie rods
Fast and easy to service with no particular tooling needed for it
Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
