Designed and manufactured to the highest of standards, the new 9033 is the most powerful, durable and reliable hammer to ever join Rammer's line up. Starting with its heavy duty housing, which features a re-enforced and wear resistant lower boot, the 9033 also features all the key traits, which professional users have come to expect from Rammer.
9033
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.
-
Flange mounting
The Flange mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
-
Heavy duty housing
Heavy 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.
-
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.
-
Stroke selector
The stroke selector makes it easy to change between short-long stoke depending on the material. Selecting stoke lengths allows you to adjest the working method to suit application and improve productivity.
-
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.
-
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 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.
Applications
-
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
-
Hammer tunneling
Tunneling with a hydraulic breaker is similar to primary breaking. It is useful in weathered rock conditions, especially in operations with ristricted clearance.
-
Primary breaking
Hammer fitted to an excavator working directly in a bench to breaks 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.
-
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.
