A plastic bottle is disclosed, which comprises a cylindrical sidewall having a predetermined thickness, an upper mouth-forming portion, a neck extending from this mouth-forming portion, a dome-shaped portion between the neck and one axial end of the cylindrical sidewall, a lower bottom-forming base

A plastic bottle is disclosed, which comprises a cylindrical sidewall having a predetermined thickness, an upper mouth-forming portion, a neck extending from this mouth-forming portion, a dome-shaped portion between the neck and one axial end of the cylindrical sidewall, a lower bottom-forming base extending from the other axial end of the cylindrical wall, all about a central axis. The bottle also has at least three substantially vertical exterior ribs that are substantially uniformly angularly spaced from each other about the axis on the neck, and these ribs have maximum cross-sectional radial dimensions along the axis generally greater than said predetermined thickness. The ribs reinforced the neck and distribute forces resulting from impact of a localized force to the mouth-forming portion towards the dome-shaped portion and cylindrical sidewall.

The device of claim 7, wherein the hydraulic assembly comprises: a) an actuator including: i) a hydraulic power cylinder securely mounted at a first end to the support member and having a hydraulic fluid connector extending therefrom; ii) a moveable plunger arm inserted within a second end of the hydraulic power cylinder to permit translational movement of the moveable plunger arm; and iii) an actuator lever attached to the moveable plunger arm and having an aperture to receive the pivot pin therethrough, the actuator lever rotating with respect to the pivot pin and moving the articulating truss boom frame when the moveable plunger arm is in translational movement; b) a hydraulic control unit connected to the support member for supplying hydraulic fluid to the hydraulic power cylinder; c) a metering valve connected to the fluid connector and operatively associated with the hydraulic power cylinder, to conduct hydraulic fluid from the hydraulic control unit to the hydraulic power cylinder; and d) a restrictor removably inserted within the metering valve and having a channel therethrough to limit the hydraulic fluid channeled to the hydraulic power cylinder. 9. The device of claim 8 wherein the metering valve comprises an outer wall hexagonal in shape to receive a standard wrench and further comprising a compressor for cleaning the device. 10. The device of claim 1 wherein the articulating truss boom frame includes: a) a back portion; b) a center beam which extends upwardly from the back portion; c) two base beams extending from the back portion and converging toward the center beam; d) a front plate attached to the center beam and the base beams; and e) a support plate connected to the back portion. 11. The device of claim 1, further comprising a hydraulic assembly for horizontally swinging truss boom comprising: a) an actuator for moving the boom including: i) a hydraulic power cylinder mounted at a first end to a support member and having a hydraulic fluid connector extending therefrom; ii) a moveable plunger arm inserted within a second end of the hydraulic power cylinder to permit translational movement of the moveable plunger arm; and iii) an actuator lever connectably attached to the moveable plunger arm and having an aperture to receive a pivot pin therethrough, the actuator lever rotating with respect to the pivot pin and moving an articulating truss boom frame when the moveable plunger arm is in translational movement; b) a hydraulic control unit connected to the support member for supplying hydraulic fluid to the hydraulic power cylinder; c) a metering valve connected to the fluid connector and operatively associated with the hydraulic power cylinder, to conduct hydraulic fluid from the hydraulic control unit to the hydraulic power cylinder; and d) a restrictor removably inserted within the metering valve and having a varying diameter channel therethrough to limit a volume of hydraulic fluid channeled to the hydraulic power cylinder. 12. The device of claim 11, wherein the metering valve includes an outside wall hexagonal in shape. 13. An articulating truss boom assembly for use with an all-terrain lift having a telescopic boom comprising; 1) a triangular articulating truss boom frame; 2) a support member attachable to the telescopic boom; and 3) an internal pivot assembly interposed connecting the support member and the articulating truss boom frame; wherein the internal pivot assembly further includes: a) a first pair and a second pair of parallel support member support plates connected to the support member; b) a first pair and a second pair of parallel truss boom frame support plates connected to the articulating truss boom frame; c) a first pivot sleeve connected to the truss boom frame support plat
