Rammer's 999 heat resistant hydraulic hammer, has been designed to withstand the toughest of applications that this size of hammers may be utilized in. Heat resistant seals and heavy duty housing protect vital components and ensure that no job is too tough.
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, smart
A connecting block allows easy adaptation to different excavator setups.
This twin handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
Easy installation with hydraulic quick hitch mounting brackets.
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.
CBE+ (Constant Blow Energy plus)
The RAMMER CBE-System (CBE = Constant Blow Energy) with the active pressure control valve and the permanently filled tubular accumulator maintains the hydraulic pressure level to ensure that each impact delivers the maximum possible power.
The RAMMER CBE system accepts a wide range of oil flows and high back pressures, allowing a wide range of carriers to be used.
The "+" stands for safe and fast connection to the carrier.
No tie rods
A smart design without tie rods allows for ideal guidance of the piston and optimal alignment of the tool.
Fast, safe and easy to maintain without the need for special tools.
Single part tool bushing retained with shared tool pin
The one-piece quick-change tool bushing inludes a thrust ring, the upper and the lower tool bushing into one component.
This quick-change tool bushing can easily be replaced on site, making maintenance easier, faster and safer.
The metallurgical industries can be broadly divided into primary, secondary, and miscellaneous metal production operations.
