Abstract

An articulating truss boom for use with a lifting machine is described. The articulating truss boom assembly includes an articulating truss boom frame, a stationary support member attachable to a lifting machine, and an internal pivot assembly having a vertical pivot axis interposed between and providing the connection between the stationary support member and the articulating truss boom frame. The articulating truss boom frame is capable of pivoting with respect to the stationary support member about the vertical pivot axis in a horizontal plane transverse to the vertical pivot axis. The articulating truss boom assembly includes a hydraulic assembly which includes a metering valve having a removable restrictor inserted therein. The removable restrictor has a constricted channel therethrough to limit the hydraulic fluid channeled to the hydraulic assembly. Rubber shock absorbing pads may be attached to at least one of the stationary support member and the articulating truss boom frame to prevent direct contact therebetween and minimize vibrational swaying.
