1322E
The Rammer 1322E has been built to last. The 850 kg hammer is suitable for carriers in the 9 to 15 tonne range. Low-maintenance design ensures lower owning and operating costs.
The 1322E features field replaceable lower tool bushing and sealed membrane-type accumulator to ensure that every blow is as hard as the previous, whilst providing protection against hydraulic spikes.
The Rammer 1322E comes with the remote monitoring hardware RD3 installed.

Features
- High pressure membrane accumulatorMembrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
- Low pressure accumulatorThis accumulator accelerates the piston at constant energy (CBE).
- Flange mountingThe Flange mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
- Heavy duty housingHeavy duty housings feature a robust structure, are made of wear-resistant steel, with minimum number of holes. Resulting in a longer housing lifetime even in the harshest of applications, reducing the cost of ownership through less maintenance.
- CBE (Constant Blow Energy)Optimum impact energy for every stroke, ensuring 100% constant power and productivity
- RAMLUBE I (optional)Carrier mounted greasing device
- RD3 incl. SAM (as standard)RD3 for SAM as standard. Online hour meter and location tracking in Google MapsTM. For further information, please contact your Rammer distributor.
- Air connectionAir connection as standard for connection to either Ramair or applications under water. Read the operator's manual and consult with your dealer.
- Ramair (optional)The RAMMER - RAMAIR air supply prevents dirt from entering the hammer housing and the impact chamber in order to achieve longest service life of the RAMMER hammer even in the most demanding applications. It also ensures that the tool grease is conveyed to the tool bushings at any time and in any position of the hammer and that no overfilling occurs. The RAMMER - RAMAIR is particularly recommended for highly abrasive and dusty materials or overhead applications, such as tunneling or robbery work.

Applications
- Boom mounted applicationsHammers for use on crushers to ensure unrestricted flow of process. Removal of boulders which are too large to fit into crusher or which block the grizzly. Absolutely necessary to ensure safe working procedures.
- Primary demolitionDemolition of standing buildings and structures.
- TrenchingTrenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
- Cutting of asphalt or frozen groundThe RAMMER "Spade tool" was specially developed for cutting of asphalt or frozen ground in road construction or infrastructure.
- Secondary breakingWhen 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.
- Underwater breakingUnderwater breaking, be it primary breaking and/or demolition is a specialized application, in which material is broken and removed by equipment which is partly or fully submerged.
