  • Publication number: 20230080378
    Abstract: A system and method is provided for enhancing the working end of a hydrovac boom hose having a longitudinal axis and a perimeter disposed transversely to the axis, the working end configured to vacuum earthy material from a digsite along the axis. A plurality of high pressure nozzles are disposable in spaced relation along the perimeter of the working end, and configured to emit high pressure fluid towards the digsite to dislodge the earthy material. The nozzles are angularly actuatable to selectively emit the high pressure fluid along a range of angles relative to the longitudinal axis, and are rotationally actuatable to selectively emit the high pressure fluid from a range of locations along the perimeter of the working end. The angular and rotatable actuation is independent of movement of the working end and/or of movement of the hydrovac boom hose.
