Large Range: 9033E
The 7,400 kg Rammer 9033E is suitable for carriers between 65 and 120 tons. 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. Heavy duty housing and in-the-field rotatable and replaceable Lower Tool Bushing allows to minimize operating costs. The Rammer 9033E comes with the remote monitoring hardware RD3 installed.9033E
