Sky-Lift ™

Forming System

2

The Sky-Lift™ “jump form” systemengineered for use on external elevatedforming applications. It can be usedwith any Symons forming system,including the Aluminum Beam,Versiform®, Steel-Ply®, Max-A-Form®

and Flex-Form® systems.

The system consists of the Sky-LiftFrame and Carriage Assembly. TheCarriage Assembly allows the gangform to be retracted from the face ofthe previously cast concrete. Thewhole Sky-Lift assembly is suspendedfrom Jump Shoes that are bolted toinserts in the previous concrete lift.These features, combined with the 8foot wide working platform, allow forstripping and cleaning of the form face.All gang form preparation can proceedwithout the assistance of a crane.

When acrane is needed, the form andplatform are hoisted as one unit andlanded into Jump Shoes. The crane isattached to the Sky-Lift unit only dur-ing hoisting, landing and reinstallationof the safety pins. This entire liftingoperation typically takes 10 minutes tocomplete.

When properly anchored, typical Sky-Lift applications will withstand ratedwind load and support platform loadsup to 50 pounds per square foot. Thiscapacity permits all forming activitiesto be performed from the Sky-Lift workplatforms.

With all of the activity described abovetaking place on the work platform, theSky-Lift system never needs to belowered to the ground or stored else-where on the project.

Waler Lift BracketsDepending on the gang form used, theSky-Lift™ assembly can be lifted bythe forms or by the walers. Whenusing the Waler Lift Bracket, it mustbe bolted to the Versiform® Waler withtwo 5/8" x 6" contour bolts and doublenutted for safety. The working load of4000 lbs (5:1 safety factor) assures asafe and secure lift. The use of alifting beam and drop lines is recom-mended when the Sky-Lift assemblyis being transported.

Work PlatformsWork Platforms are used to retract thegang form approximately 30" from thepoured concrete wall. Final gang formadjustments, plumbing, and JumpShoe attachment can all be done fromthe Work Platform. The Work Platformalso can be used to clean and storegangs. This operation saves timecompared to the conventional methodof lowering the gangs by crane to cleanand store them. The Work Platform istypically constructed with three alumi-num beams secured to the Sky-Liftframe. The aluminum beams are de-signed with a 2" x 2" wood nailer stripto fasten ¾" plywood for the platformdecking.

Trailing PlatformsTrailing Platforms provide a 30" widework access to the previously pouredconcrete wall. This allows a safeplatform to patch tie holes, removeJump Shoes and complete any othernecessary finishing work. The TrailingPlatform is constructed with alumi-num beams and ¾" plywood for theplatform decking.

Screw Jack AssemblyThe Screw Jack Assembly consists ofthe Carriage Waler Bracket and the1½" diameter screw jack. The Car-riage Waler Bracket is bolted onto theVersiform® Waler with two 5/8" diam-eter x 5" contour bolts and the ScrewJack is pinned to the Glide Rack™.The assembly supports the gang formand allows vertical adjustments of upto 10½" for the purpose of aligning theoutside forms with the inside forms fortie placement.

Jump ShoesThe Jump Shoe is bolted to an insert inthe previous poured concrete. A re-movable pin in the Jump Shoe sup-ports the end of the Sky-Lift™ Frame.A locking pin in the Jump Shoe en-gages the top member, securing theFrame against possible uplift forces.This safety pin cannot be engaged ifthe frame is not correctly seated in theJump Shoe, and provides a positivesafety indicator before the crane isdisconnected.

Wall BracesThe heavy duty, all steel Wall Bracesare designed to simplify wall formalignment. Wall Braces are attachedto the top of the gear housing on theretractable carriage, and to the gangform waler with 5/8" diameter bolts. TheWall Braces are used to strip the gangform from the newly placed concretesurface. Once stripped, the entireassembly can move away from thewall on the Sky-Lift Glide Rack.

Sky-Lift™ Assembly Sequence

FirstLift

First liftOnce the gang forms are assembled,the Sky-Lift side should be set first.Inserts are positioned on the face ofthe gang form for the Jump Shoes andSky-Lift Frame connections. Rebar isthen set in place and the opposite gangform is secured with ties. After theconcrete walls are poured and thegang forms stripped, the Jump Shoesare bolted into the inserts.

Second liftThe Sky-Lift Frame assembly is liftedinto position, lowered onto the JumpShoe, and secured with the safety pin.The Sky-Lift Frame is now mounted tothe wall and ready to have the gangform and Work Platform attached. TheWall Brace is pinned to the waler andthe gear housing, so the entire unit canbe positioned. The crane now can besafely released and the gang formmoved forward by turning the gearassembly with a wrench. Inserts areagain placed and the forming sequencerepeats.

Third liftThe forming sequence for the third liftis similar to the previous lifts, exceptnow the Trailing Platform has beenadded. The extension bracket is se-cured to the Sky-Lift frame. Alumi-num beams, ¾" plywood decking, andguard rails are then added. Whenlifting the gang and platform to the nextposition, the Trailing Platform will swinginto position. Install the remaining 1"diameter pin into the Extension Bracketto complete the Sky-Lift assembly.

StrippingAdditional lifts are achieved by firstremoving all ties and retracting thegang forms using the Wall Brace andproviding access using the GlideRack™ carriage. Place the JumpShoes for the next lift and perform anymaintainance that may be needed.

LiftingJust before lifting, remove all of theLock/Safety Pins from the JumpShoes. When the Sky-Lift Assemblyis initially lifted, the unit may tilt slightly.To adjust the unit to fly vertically, raisethe Sky-Lift Assembly, making surenot to lift clear of the Jump Shoes. Ifthe front of the platform dips and therear of the platform raises, move theSky-Lift Carriage forward. If the rota-tion is reversed, move the Sky-LiftCarriage backward. Additional fineadjustment can be achieved with theWall Brace.
