Three vacuum boom tube and hose design options are available on AllExcavate hydroexcavation models from Vacall. One design uses a flexible, heavy-duty, full-length rubber hose with a gum-rubber lining that runs from the turret mounted on the debris tank out to the pickup point. The second option has a steel tube-in-tube boom and intake that connects to an identical rubber hose elbow leading to the pickup point. The third option has a steel tube-in-tube with steel elbow boom and intake tube. The unit can generate up to 27 inches Hg and up to 5,800 cfm. Used in combination with the machine’s high-power waterjetting forces, it can loosen and remove dirt and other material from around utility lines and foundations where mass excavation is not possible. 800/382-8302; www.vacall.com.
