TRENCHING SYSTEM |
摘要 |
A system for uncovering and sealing a narrow trench. The system comprises several subsystems, including a work machine, a frame for providing a seal with the surface to be trenched, a saw blade, a vacuum system, a system for placing product, and a resealer. The blade includes rotatable tooth bits, which may be rotated and secured to create a blade for narrower or a wider trench. A removable cover and the blade are easily changeable. A ground engaging surface on the frame is manipulated to maintain a seal with changing ground surfaces. Additionally, the vertical location of the blade within the frame is adjustable to create a deeper or shallower trench. |
