Large Range: 4099E
The 3,380 kg Rammer 4099E is suitable for carriers in the 36 to 55 tonne range. Designed by using a revolutionary new operating principle that combines stroke length, blow energy and Rammer’s idle blow protector, allowing the hammer to be adjusted to match individual carriers and applications, improving hydraulic efficiency and safety. The Rammer 4099E comes with the remote monitoring hardware RD3 installed4099E
