Equipment

Rammer Hammer 3288E Large Range – New Design

The 2,350 kg Rammer Hammer 3288E – New Design

A hydraulic hammer is suitable for carriers in the 26 to 42-tonne range.

Designed by using a revolutionary new operating principle that combines stroke length, blow energy and Rammer’s idle blow protector, allowing the hammer to be adjusted to match individual carriers and applications, improving hydraulic efficiency and safety.

The Rammer 3288E 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 the field.

Service access to high-pressure membraned accumulator

This design allows faster and safer on-site troubleshooting and service.
Optimal setup for air cargo.

Indexable power cell (left or right-handed)

The ability to rotate the power cell 180 degrees is part of the twin-handed design, allowing for optimal mounting on both left and right-handed carriers, prolonging the service life of the hose connections.

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.

Heavy Duty housing (round corners)

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- and noise dampening.

Resulting in a longer housing lifetime even in the harshest of applications, reducing the cost of ownership through less maintenance.

Available for: 1655E, 2166E, 2577E, 3288E, 4099E and 5011E.

Super Duty housing (sharp corners)

Super Duty housings are designed for the toughest of applications, featuring a robust structure. They are made of wear-resistant steel, with a minimum number of holes and heavy-duty wear plates for optimum vibration- and noise dampening.

Resulting in a longer housing lifetime even in the harshest of applications, reducing the cost of ownership through less maintenance.

Stone claws on housing

Stone claws are ideal wear parts for material handling, especially useful in boulder breaking and in concrete demolition.

Optimised hydraulic connection points towards the carrier

The relatively short hydraulic hoses go upwards from the hammer to the carrier boom. This allows full utilization of the working length of the hammer in narrow applications.

In demolition, trenching or underwater applications there is little contact to the material.

In applications with quick hitch mounting, brackets ask your hammer distributor for smart solutions.

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.

RamValve

More efficient than relief/check valves, Ramvalve detects overflow, prevents damage from system overload and protects against premature failure.

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.

Field replaceable lower tool bushing.

Field replaceable lower tool bushing eliminates transport to service workshop.

RAMLUBE I (optional)

Carrier mounted greasing device.

RAMLUBE II (optional)

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 using 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. MyFleet (as standard)

RD3 for MyFleet as standard. Online hour meter and location tracking in Google MapsTM.

For further information, please contact your Rammer distributor.

Air Connection

Air connection as standard for connection to either Ramair or applications underwater. 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 the 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 tunnelling or robbery work.

Applications

Primary breaking

Hammer fitted to an excavator working directly in a bench to break away rock which can then be removed by truck. This is most commonly used where blasting is not allowed.

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.

Primary demolition

Demolition of standing buildings and structures.

Secondary demolition

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

Underwater breaking

Underwater breaking, be it primary breaking and/or demolition is a specialized application, in which material is broken and removed by equipment that is partly or fully submerged.

Trenching

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