The S850SL is an All-Purpose Mid-Size Slipform Paver with Swing Legs. With the success of the G&Z S600 in the domestic and international markets, the patented AccuSteer: Slew Drive Track Control System and SmartLeg: Swing Leg System have been made available as options on the G&Z S850 in lieu of the reliable and time-tested QUADRA BOLSTER system.

The S850SL is ideal for highway and airport paving, city streets, secondary roads, ramps as well as canal lining applications. The S850SL has been engineered to make contractors more productive. Its time saving options provide the contractor with the opportunity for more paving hours in the day and more paving days during the season.
