The Unveiling of the G&Z S850SL

Ripon, California U.S.A. November  14, 2012 – Guntert & Zimmerman (G&Z) is proud to announce the New S850SL: 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.

AccuSteer consists of slew drives that are mounted on top of the crawler track yokes that are used to steer the tracks in lieu of steering cylinders.  AccuSteer drives are powered with hourglass worm technology to give long life, high accuracy and extremely high maneuverability.  AccuSteer allows the operator to independently rotate the tracks almost a full circle, providing exceptional on site maneuverability and rapid swing leg relocation for paving and transport without the need to re-pin steering cylinders.

Working in tandem with AccuSteer, SmartLeg allows the operator to adjust the swing leg angle on the fly while automatically keeping the crawler track straight ahead.  This offers a high level of flexibility for the contractor to maneuver around track line obstacles (e.g. fire hydrants, airport runway lights, etc.) on the fly and without stopping to make a mechanical swing leg adjustment or re-clocking the steering transducer.  With SmartLeg, the process for transforming the S850SL into the transport configuration can be semi-automated.  This simple process dramatically saves time over other conventional four track slipform pavers.  Using the combination of the 90 degree, AccuSteer and SmartLeg, the four swing bolsters and crawler tracks are semi-automatically walked into the outboard, transport position in approx. 30 minutes.

Where Does the G&Z S850SL Fit in the Market?

As G&Z continues to explore ways to increase available paving time and decrease set up time, the S850SL is designed to fulfill the need for a versatile, maneuverable, time saving mid-size paver that has the ability to achieve good smoothness numbers.  The S850SL Paver is one of the narrowest profile mid-size pavers on the market.  When equipped with special narrow grouser pads, the S850SL can work next to a temporary barrier wall on a companion lane trackline as little as 12” (30cm) wide with and without a DBI.  The S850SL has been engineered to make contractors more productive.  The S850SL time saving options provide the contractor with the opportunity for more paving hours in the day and more paving days during the season.

S850SL Applications

The S850SL Mid-Size Concrete Slipform Paver is an “All-Purpose” mid-size paver.  It is ideal for city streets, secondary roads, highway and airport paving, ramps as well as canal lining applications.

S850SL Specifications

The G&Z S850SL features a patented double telescopic tractor frame, access walkway, and hose hinges for a nominal working range of 12'-0" to 26'-0" (3.66 m to 7.92 m) with up to 7’-0” (2.13 m) of telescopic ability per side - the widest range in the industry. With the addition of optional bolt-in tractor frame extensions, the S850SL tractor can extend up to nom. 39'-5" (12 m).  When the tractor frame is equipped with G&Z’s Patented JC Extender System, major tractor width changes can be done in under one hour.  The S850SL is available with G&Z’s patented and time saving TeleEnd: Telescopic Paving Kit End Sections which allow hydraulic telescopic ability of 3’ (915mm) per end or 4’ (1250 mm) with the New TeleEndXL. The S850SL can be equipped with a mechanical dowel bar inserter (DBI) and can be supplied with hydraulic or electric poker vibrators.  The paving kit, front tie bar inserter and many of the other optional attachments on the S850SL are interchangeable with other G&Z paver models, giving the contractor a more versatile fleet of paving equipment.

MCM Paves Dallas Love with G&Z S850

Concrete Slipform Paver

Compared to mainline highway paving, slipforming concrete taxiways, aprons, and runways at an active airport is a challenging business. Production is hampered by the many small, irregularly shaped pieces of pavement that need to be paved one at a time. 

That’s the situation faced by MCM at Dallas Love Field Airport, a heavy civil and building contractor with corporate offices in Irving, Texas. At Dallas Love Field Airport, the city of Dallas and Southwest Airlines are collaborating to build a $500 Million-plus airport renovation project. A number of gates must remain open during four years of construction, which will wind up in 2015.

MCM has a $68 Million contract to remove concrete, grade the subgrade and base, relocate utilities (including a new aircraft refueling system), and place 298,000 square yards of new concrete pavement. Most of that is 17-inch jointed plain concrete with no steel. There are smaller amounts of 15-inch and 8-inch concrete pavement....Read More.
