Abstract

A hydraulic pivot arm positioning assembly includes a forward and aft pivoting arm on both the left and right ends of a paving machine configured to operate in a paving direction. Hydraulic cylinders or other linear actuators enable the forward and aft pivoting arms to rotate automatically through at least a 90-degree range including at least an operating configuration, wherein the pivoting arms extend parallel to the paving direction, and a transport configuration, wherein the pivoting arms extend parallel to the transverse framework of the paving machine, narrowing its overall width. The use of linear actuators enables the pivoting arms to change position with minimal downtime to the paving machine, and without the need for manual repositioning, disconnection, or reconnection of components or accessories of the pivot arm positioning assembly.
