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.
- Heat Resistant Seals
The twin-handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
Single lower tool bushing
The single lower tool bushing, replaces the need for an upper and lower tool bushing, whilst being field replacable. This makes for faster and easier field service.
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.
- CBE+ (Constant blow energy plus)
No tie rods
Fast and easy to service with no particular tooling needed for it
