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 for which professional users have come to expect from Rammer.
The Flange mounting mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
More efficient than relief/check valves, Ramvalve detects overflow, prevents damage from system overload and protects against premature failure.
Idle Blow Protector
Idle Blow Protection 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.
The twin-handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
Ramlube II (Optional)
Mounted greasing device, with adjustable flow and cartridge feed.
Membrane type accumulator
Membrane-type accumulator eliminates nitrogen leakages, ensuring maximum piston acceleration and removing the need for time-consuming recharging.
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)
A built-in pressure control valve maintains hydraulic pressure levels to ensure that every blow delivers the maximum power possible optimum productivity.
VIDAT tie rods
Vibration Dampened Tie Rods, spherical tie rod nuts and damper bushings ensures piston moves freely for longer, more productive working life.
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.
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.
Tunneling with a hydraulic hammer is similar to primary breaking. It is useful in weathered rock conditions.
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.
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.
