General information:

Safe producing of bridge moldings ROBUSTA formwork carriage for molding external and internal bridge edge beams individual additional solutions for molding internal bridge edge beams ROBUSTA reworking carriage for conventional formwork-, installing- and repairing works (see page 15)

All 3 systems work after the same principle:The mounting effort on site is reduced to a minimum by pre-mounting in the factory, to prevent unnecessary and uncalculatedcosts of staff, material and delay of time.Additional these system solutions are offering extensive safety equipments and therefore protect crew and the exposed areaunderneath the bridge.

BRIDGE CONSTRUCTION

FORMWORK CARRIAGE FOR EXTERNAL BRIDGE EDGE BEAMS8All construction parts in a survey:The very sturdy formwork carriage consists of a movable basic rack with two cantilever girders, to which the working plat-form is attached, including a continuous side protection.When working at bridges in big heights safety has first priority. Thats why we drop the use of wood for the side protec-tion elements. The continuous plancking made of riffle sheet with lateral edge setting without gaps will guarantee a safeprotection against falling of small parts. This is very important at bridges crossing busy traffic routes.

The side protection is build of plug-in type aluminium frames, which are as strong to be also usable as a ladder.

To adjust the formwork steel walings, all spindles can be reached easily from one point. The adjusting is done easily with afree wheeling wrench with a long lever arm.

The steel construction of the carriage consists of only 3 mounting groups:

1. basic rack carriage with ballast W = 2400 kg (without ballast)

2. cantilever girderswith diagonal bracing and slidingundercarriage to suspend the working

platformW = 3950 kg

3. working platformcomplete with formwork walings and

side protection framesW = 2300 kg

Mounting: quick and safe

The mounting of the carriage is very quick and easy to realize with less staff because of premounted elements delivered tosite. This helps to prevent accidents during mounting and using.We will send a foreman on request for first instructions, charging only a flat rate.

1. step:connecting of the premounted basic racks

3. step:onnecting of 2 cantilever beams to 1 element with 3 cross struts and 2 diagonal bracings

2. step: placing of the concrete ballast

4. step: placing onto the carriage and installation of the rear anchoring

5. step:mounting of the vertical beams with steel walings to the platform

Delivery of the premounted elements, max. width = 3.00 m

Adjusting of the bottom- and lateral sideformwork

The big advantage in handling our carriage is the separatedhorizontal and vertical adjustment of the formwork walings.

Universal and quick possibilities of adjustment:All spindles to adjust the formwork walings can be reachedeasily from one side, standing on the platform.The adjustment at all spindles can be done quickly with thehelp of the delivered free wheeling wrench SW 46.During construction we took careof the fact that allhorizontal and vertical directions of the steel walings can beadjusted separatly and independent from each other.The steel walings for the side formwork can be inclined with

2 adjustment spindles independent to the vertical beam of theplatform, without adjusting the whole platform.The special effect: The steel waling adjusted to a specialangle can be adjusted subsequently in height withoutchanging the angle.The result is a enormous quick adjusting and time saving.Additionally an adjustable brace is fixed at the lower side ofthe girder to adjust the complete suspended construction inhorizontal direction.With the help of the inclinded brace the vertical girder willbe placed into the vertical position with the formworkconstruction.After that the fine adjustment of the formwork as decribedabove can be done.

FORMWORK CARRIAGE FOR INTERNAL BRIDGE EDGE BEAMS8

Movable unit L = 5.0 m.The main girder which is placed ontothe secondary beams can be shiftedlateral and adjusted exactly over the gapbetween the bridges.The working platform at the lowerbridge side will be suspended at twooversized tie rods and is thereforevariable in height.These units can be moved without pro-blem with the self drive lifting carriage.The edge beam formwork is held byadditional separate tie rods.

The 4 corner props of the platform haverollers, which have a loose contact tothe lower bridge side.Because these corner props areadjustable separately in height theplatform can be adjusted to heightdifferences in the direction of theroadway. (or of the superstructure ).In that way a lateral tilting of theplatform as a result of one sided loads isprevented.These 5 m long units can be placed oneafter the other in random numbers.

For the casing and striking of theinternal edge beams we provide a

mechanism using steel wedgeinsertions. The side formwork made ofwood must have according inclinedwooden layers on the back side.To adjust the correct lateral distance forthe gaps between the edge beams thewedges at the spindles can be lifted orlowered exactly in height.For striking the wedge layers will belifted, the side formwork will come freeand can be removed upwards.

The basic racks with cantilever girders and ballast placed on one superstructure are identical with the construction for the

external edge beams. A main girder willl be placed exactly over the gap between the bridge onto the cantilever beams .The suspension of the working platform is done with an according number of tie rods, the same way as with the carriage atboth sides of the bridge (see drawing page 10).

Easy to set up from a few pre-assembled units. Wrap-around side protection including all connection materials included with delivery.

No emergency solutions of wood are required! Safe and fast work for renovation, forming and concrete works on bridge molding formwork. Modular set-up system adjusts to different bridge shapes. Effective protection against small parts falling off due to closed floor covering of the work platform

made of corrugated sheet metal. The sides are also raised all around.

Because of its compact design and dimensions, theROBUSTA reworking carriage is fast and uncomplicated toset up, move and change over. It also offers all the safetyadvantages of a large forming carriage.It can be easily and economically adapted to your ownspecific usage conditions. The reworking carriage consists ofa sturdy, base frame made of steel. It is movable with4 wheels and very resistant to bending. The boom girders withattached work platform and side protection are mainly madeof light-weight aluminium sections.When working on bridges at great heights, safety is thetop priority. Because of this, we consistently avoid the useof wood in construction parts intended to provide sideprotection.The closed base covering made of corrugated sheet metalwith a raised side piece guarantees reliable protection againstsmall pieces rolling off and falling down. This is especially

important for bridges over travelled traffic routes.The side protection on all four sides is formed from plug-inaluminium frames that are so sturdy that they can be usedas a ladder for climbing up and down.
