Large Range: 3288E
The 2,350 kg Rammer 3288E hydraulic hammer is suitable for carriers in the 26 to 42 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 3288E comes with the remote monitoring hardware RD3 installed.3288E
