SLIP FORM PAVING MACHINE AND METHOD OF CONTROLLING A SLIP FORM PAVING MACHINE

A slip form paving machine includes a machine frame (22), a plurality of ground engaging wheels or tracks (30), and front and rear height adjustable lifting columns (32) adjustable to adjust a longitudinal inclination of the machine frame in a paving direction (12). A slip form mold (24) is supported from the machine frame. The machine further includes a front stringline sensor (60F), a front sensor actuator (62F) arranged to adjust a vertical position of the front stringline sensor relative to the machine frame, a rear stringline sensor (60R), and a rear sensor actuator (62R) arranged to adjust a vertical position of the rear stringline sensor relative to the machine frame. A controller (202) is configured to send command signals to the front and rear sensor actuators to cause an adjustment in the longitudinal inclination of the machine frame.
