FLICK RAMMER:
The demand for increasingly more effective, higher performing, and consequently, more complex weapon systems have accelerated the development of semi- and fully-automatic loading systems for both mobile and stationary gun systems. Requirements such as:
- burst fire
- higher rates of fire
- consistent reliability of loading cycles
- smooth ammunition handling
- remote control of weapon systems
- loading in isolated or poorly accessible compartments
- crew reduction
have created a need for new solutions.
Flick Rammers were developed specifically to answer these needs and can be installed in a variety of artillery systems:
- field howitzers
- self-propelled howitzers
- fortress guns
Flick Rammers facilitate high rates of fire and guarantee a consistent ramming depth at all elevations. Because of their compact design concept and simple controls, Flick Rammers are eminently suitable for retrofitting. Depending on the space available on the gun and the ammunition loading mode desired, Flick Rammers can be installed in both horizontal and vertical loading arm options. Through the use of a flow control system for speed setting rather than the more conventional pressure type, Flick Rammers provide outstanding advantages:
- low system pressure (120 bar)
- high operational safety
- simple operation
- high reliability
- low power consumption
- low maintenance
- simple retrofitting
- minimal dimensions
- high capacity reserves
Under field conditions, a wide variety of different guns using CWDT Flick Ramming Systems have demonstrated outstanding results, firing thousands of rounds of live ammunition reliably. For example, using a fully automatic fortress gun, only 10 seconds were required to fire a complete 3-round burst.
Flick Ramming System
for M 109 self-propelled gun. CWDT has specifically developed and tested a system which is particularly well suited to retrofitting existing or equipping new M 109 self-propelled guns.
- Flick Ramming system installed in an M 109 self-propelled gun in the loading position.
- Flick Ramming system in the ramming position.
