The Rammer 1322 has been built to last. Featuring a sealed membrane-type accumulator to ensure that every blow is as hard as the last, whilst providing protection against hydraulic spikes. The 1322 has a field replaceable lower tool bushing and it's low-maintenance design ensures lower owning and operating costs.
The Flange mounting mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
Membrane type accumulator
Membrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
Heavy Duty Housing
Heavy duty housings feature a robust structure, are made of wear-resistant steel, with minimum number of holes and heavy duty wear plates for optimum vibration dampening.
Resulting in a longer housing lifetime even in the harshest of applications, reducing the cost of ownership through less maintenance.
FBE (Fixed blow energy)
The built-in pressure control valve maintains hydraulic pressure levels to ensure that every blow delivers the maximum power, yielding optimum productivity in all applications.
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.

Blockage and build-ups
Stationary pedestal booms equipped with breakers are used extensively on crushers for breaking oversized boulders and clearing material for smooth and continuos feed flow.
When blasted rock is too big for the feeder or crusher, secondary breaking is needed to get the boulders down to size. The type of rock dictates the effectiveness of the process, with brittle rock giving the best performance.
