The Rammer 9033E 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.
Heavy duty housing and in-the-field rotatable and replaceable Lower Tool Bushing ensures minimized operating costs.
The 9033E is suitable for carriers in the 65 to 120 tonne range and it comes with the remote monitoring hardware RD3 installed.
