Abstract: A paving machine includes a mold coupled to a telescopic frame member, by which the mold side-shifts relative to a main frame. A tight clearance between the paving machine and a surface being paved may be achieved by the ability to side-shift the mold. The paving machine may also include a number of vibrator motors. A flow to the vibrator motors may be controllable by a manifold controller. The manifold controller is located on an end of the telescopic frame member. By locating the manifold controller on the telescopic frame member, an operator of the paving machine may both stand on the telescopic frame member to watch the paving mold and adjust the settings of the vibrator controller. This is advantageous in allowing the operator to achieve proper concrete consolidation by visual feedback without leaving the telescopic frame member.

Abstract: A leg assembly includes a guide tube, a power drive coupled to a flange of the guide tube, a steering ring coupled to the power drive, a tube weldment coupled to the steering ring, and a hydraulic actuator coupled within the guide tube and within the tube weldment. The power drive includes a slew drive or a hydraulic cylinder steering assembly. The tube weldment is translated through the power drive by the actuator. The steering ring includes one or more pistons by which relative rotational movements may be imparted to the tube weldment by a socketing action. The steering ring is rotated by the power drive. Thus, the guide tube may be rotated relative to the tube weldment.

The power drive includes a slew drive or a hydraulic cylinder steering assembly. The tube weldment is translated through the power drive by the actuator. To achieve a minimal width, the tube weldment includes a keyway. The steering ring includes a key by which relative rotational movements may be imparted to the keyway. The steering ring is rotated by the power drive. Thus, the guide tube may be rotated relative to the tube weldment.

Abstract: A method for operating a ratchet assembly. The method includes, when a ratchet lock mechanism is in a first locked position, causing a drive mechanism to rotate by operating a steer cylinder in a selected direction until a first predetermined value, which may be associated with an amount of rotation of the drive mechanism, is reached. The method includes unlocking the ratchet lock mechanism, and resetting the steer cylinder by operating the steer cylinder in an opposite direction until a second predetermined value is reached. The method includes locking the ratchet lock mechanism in a second locked position, and, upon locking the ratchet lock mechanism in the second locked position, causing the drive mechanism to further rotate by operating the steer cylinder in the selected direction until a third predetermined value is reached, wherein the third predetermined value is associated with a selected amount of rotation of the drive mechanism.

Abstract: A ratchet assembly may include a steer ring, a steer ring side structure, a steer cylinder bracket arm, a steer cylinder, a ratchet lock gear, a steering collar, a ratchet cylinder, a ratchet lock bar, and at least one sensor. When in a particular locked position, operation of the steer cylinder rotates the steer ring, the ratchet lock gear, and the steering collar. When in an unlocked position, operation of the steer cylinder rotates the steer ring around the ratchet lock gear.
