The Rammer 4099E large range rockbreaker has been designed by using a revolutionary new operating principle that combines stroke length, blow energy and Rammer’s idle blow protector, allowing the rockbreaker to be adjusted to match individual carriers and applications, improving hydraulic efficiency and safety.
The 4099E is suitable for carriers in the 36 to 55 tonne range and it comes with the remote monitoring hardware RD3 installed.
