Automatically adjusting swing legs for mounting and aligning and reorienting crawlers
A paving machine including a modular frame, a plurality of swing legs pivotable relative to the frame, a jacking column secured to each swing leg, a crawler track, a slew gear drive, and angular position transducers for measuring an angular position between the swing leg and the modular frame, and an angular position of the crawler track relative to the jacking column. Feedback from the transducers facilitates maintaining position of the crawler track. The jacking column can include telescoping outer and inner tubes, a vertically oriented hydraulic actuator including a cylinder and a piston operable within the outer and inner tubes, and spaced apart axial bearings coupled to the outer tube and/or the inner tube. The slew gear drive can be secured between the inner tube and a yoke and capable of steering the crawler track under load without lifting the crawler track.
