Tunkers dampeners minimize wear and tear on cranes, which helps projects to run more safely and more smoothly. Another major benefit of the dampener is that hydraulic-boom cranes can safely be used for vibratory hammer operation. Many major crane rental companies now require the dampener due to the high level of protection it provides the crane.
