Abstract
This specification discloses an off-road vehicle that both articulates and oscillates, thereby enabling achieving a highly maneuverable, more nearly level working platform from which attachments can be operated with utmost effectiveness. The vehicle is characterized by front and rear sections, each carried by two wheels and connected at an articulating steering joint with steering rams and steering means; and a mechanism on the front section for leveling the front section. The leveling mechanism includes a front frame member that supplies the main structural support for the front section and is pivotally connected with a front axle, with hydraulic rams disposed on either side of the pivotal connection and connected via control valve with a source of high pressure hydraulic fluid for attaining and holding a predetermined, or substantially level, position. In the preferred embodiments, a lock valve is interposed between the control valve and the hydraulic rams for providing a positive liquid lock to hold a predetermined position. Also disclosed are preferred embodiments.
