ARTICULATED BOOM FOR HYDRO-EXCAVATION VEHICLE

摘要

An articulated boom for a hydro-excavation vehicleincludes a boom support adapted to be mounted on an hydro-excavation vehicle for rotation about a substantially verticalrotational axis. A primary arm section is provided which iscapable of being raised and lowered about a substantiallyhorizontal pivot axis. A secondary arm assembly is providedhaving one or more supplemental arm sections which are capableof side to side movement about vertical pivot axes. A handsection is provided which is capable of being raised andlowered about a substantially horizontal pivot axis. Thearticulated boom, as described, has an extended reach which canreach around obstacles and enable longer sections of a lineartrench to be completed before having to move the hydro-excavation vehicle.
