The use of advanced hydraulics, materials technology, strength calculations, impact wave theory and production technology has enabled Rammer to create hydraulic hammers which are powerful, durable, cost-effective and the undisputed leaders in their class.

The Rammer 9033E has been designed 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.

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.
