2155E

Rammer 2155E embraces the very latest in hydraulic hammer design. The 1240 kg hammer is suitable for carriers in the 14 to 26 tonne range.

The 2155E has a slim body, robust housing made of wear resistant steel and a replaceable bottom plate and other smart features. A key feature is its design that provides exceptional flexibility to match the hammer precisely to application and material requirements by choosing additional parts from a range of options as “retrofit”.

The Rammer 2155E comes with the remote monitoring hardware RD3 installed.

Features

High pressure membrane accumulator

Membrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
Twin handed

The twin handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.

Easy installation for hydraulic quick hitch mounting brackets.
Vibration and sound suppressed

Less vibrations and at the same time significantly lower noise levels are achieved with this ultra-modern, low-wear design.

This protects the operator, the carrier and relieves the environment.

This extends your range of applications on narrow job sites and wherever noise protection is required.
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.
Idle blow protector

The Idle Blow Protection (IBP) ensures the hammer cannot be operated until pressure is placed on tool. This eliminates tie rod stress, reduces oil overheating and protects against premature failures.
VIDAT tie rods

Vibration dampened, external tie rods (VIDAT) with spherical tie rod nuts and elastomeric vibration dampers.

No special tools are required for service.

This design guarantees a safe, fast and error-free installation (without torsion) and extends the service life of your RAMMER hammer.
Fast-change tool system

Quick and safe tool change system transverse to the hammer. No need to reach under the hammer during tool change.
RAMLUBE I (optional)

Carrier mounted greasing device
RAMLUBE II

The RAMLUBE II is a state-of-the-art, convenient and automatic lubrication system for RAMMER hydraulic hammers, which significantly extends the service life of wearing parts.

The RAMLUBE II is mounted on your hammer housing and is a self-venting impulse lubrication system.

The grease volume of the RAMLUBE II can be externally adjusted.

We recommend to use our original Rammer tool greases, which are developed for hammer applications.

There are available three different greases: original Rammer Tool Grease for standard applications, Rammer Meissel Paste for special applications and Artic Tool Grease for cold climate conditions.
RD3 incl. SAM (as standard)

RD3 for SAM as standard. Online hour meter and location tracking in Google Maps^TM.

For further information, please contact your Rammer distributor.
Air connection

Air 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.
Wheeled excavator hammer

Applications

Boom mounted applications

Hammers 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 demolition

Demolition of standing buildings and structures.
Trenching

Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
Secondary demolition

Demolition of larger pieces on the ground (size reduction, separation and preliminary sorting tasks)
Secondary breaking

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.
Underwater breaking

Underwater 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.
