Abstract
A tandem drum-type pavement compacting machine having front and rear drums journaled in substantially identical yokes, each of which is connected with the chassis of the machine for steering rotation about a vertical axis which intersects the axis of its respective drum midway of its axial width, and wherein the front end portion of the chassis to which the yoke of the front drum is steerably connected, is joined to the main section of the chassis by a trunnion or swivel connection that provides for relative oscillation or rocking motion between the front and rear drums about a horizontal axis extending fore and aft along the centerline of the machine and intersecting the vertical steering axes of the drums. An operator's platform is fixed with respect to the yoke of the rear drum and overlies the rear portion of the main section of the chassis.
