Hitachi compaction rammers - Compaction is an important part of the construction process – and our ZV-R series of vibratory rammers are vital tools for the job. With a powerful force and high levels of propulsion, they make light work of soil and sand compaction. Thanks to user-friendly controls, an accessible engine-off switch and the low-vibration handle, you can feel the benefits of the ZV-R range. The lightweight design is easy to manoeuvre, perfect for confined spaces. The four ZV-R models share several common components, including crank, handle and cylinder units, and the ramming shoe. So you’ll find them easy to maintain and replace, which minimises potential downtime on the job site.
