The 255 is your no fuss, plug and play solution for carriers between 0.9 and 2.5 tons. Protected by their box type housing, these hammers produce less noise and vibration, whilst are strong enough to take a beating.
The Flange mounting mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
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.
CBE (Constant blow energy)
same impact energy for every stroke, ensuring 100% constant power and productivity
- Cast Housing
The light weight design allows the use of smaller carriers without compromising the stability of the carrier.
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.
