Description
The new 770 m Baldwin motorway bridge over the Connecticutriver at Saybrook and Old Lyne has been built using a newmethod of post-tensioned pre-cast segmental concrete
The system used an overhead gantry to transport and positionthe prefabricated segmental concrete sections amongst theheaviest and widest ever used for balanced cantilever con-struction The 2 hydraulic TIRAK T-3000 hoists were used forhandling the overhead gantry These large 3 tonne capacityhoists operated in both directions for achieving the necessaryto-and-fro movements to position the segments
The pulling effort was chec ked by 2 DYNAFOR load ind icatorswith remote display mounted in the c rane cabin
The 2 post-tensioning p latforms were lifted and lowered by 2x2TIRAK T-1000 machines reeved on 4 p arts of wire rope (photo

Description
The new 770 m Baldwin motorway bridge over the Connecticutriver at Saybrook and Old Lyne has been built using a newmethod of post-tensioned pre-cast segmental concrete
The system used an overhead gantry to transport and positionthe prefabricated segmental concrete sections amongst theheaviest and widest ever used for balanced cantilever con-struction The 2 hydraulic TIRAK T-3000 hoists were used forhandling the overhead gantry These large 3 tonne capacityhoists operated in both directions for achieving the necessaryto-and-fro movements to position the segments
The pulling effort was chec ked by 2 DYNAFOR load ind icatorswith remote display mounted in the c rane cabin
The 2 post-tensioning p latforms were lifted and lowered by 2x2TIRAK T-1000 machines reeved on 4 p arts of wire rope (photo

ProblemThe work consists of tensioning the prestressing wire ropes onthe inner part cutting the extra length of the ropes and injectinga protective cement to prevent corrosion
SolutionThe platforms move two by two along the ribs They have threefunctions ndash lifting personnel and materials up to the working level ndash working on the left and on the right of eac h rib for the
positionning of the prestressing ropes and tensioning jacks ndash handling of the tensioning jac ks (weig ht 1600 kg) by means
of an electric pulley block which moves along a mob ile beam(PA10718) A metallic frame construction is needed to
support the beam It is an integral part of the platformThe platforms come in from the top by means of a crane(PA1071619)

Description
The new 770 m Baldwin motorway bridge over the Connecticutriver at Saybrook and Old Lyne has been built using a newmethod of post-tensioned pre-cast segmental concrete
The system used an overhead gantry to transport and positionthe prefabricated segmental concrete sections amongst theheaviest and widest ever used for balanced cantilever con-struction The 2 hydraulic TIRAK T-3000 hoists were used forhandling the overhead gantry These large 3 tonne capacityhoists operated in both directions for achieving the necessaryto-and-fro movements to position the segments

Application Handling an overhead gantrySite New Baldwin motorway bridge
Saybrook Connec ticutUSACustomer Joint-venture PERINI PCL C amp GEquipment 2 hydraulic TIRAK T-3000 hoists
Description
The new 770 m Baldwin motorway bridge over the Connecticutriver at Saybrook and Old Lyne has been built using a newmethod of post-tensioned pre-cast segmental concrete
The system used an overhead gantry to transport and positionthe prefabricated segmental concrete sections amongst theheaviest and widest ever used for balanced cantilever con-struction The 2 hydraulic TIRAK T-3000 hoists were used forhandling the overhead gantry These large 3 tonne capacityhoists operated in both directions for achieving the necessaryto-and-fro movements to position the segments
The pulling effort was chec ked by 2 DYNAFOR load ind icatorswith remote display mounted in the c rane cabin
The 2 post-tensioning p latforms were lifted and lowered by 2x2TIRAK T-1000 machines reeved on 4 p arts of wire rope (photo

each fitted with ndash 4 motorised TIRFOR TU-16H machines ndash 1 four-way power pack ndash 4 BLOCSTOP BS 20301 safety devices ndash 8 wire ropes C12 80 m long ndash 2 overhead trolleys
Description of applicationProblem The tensioning of the prestressing ropes of 5 silos (3
for clinker material and 2 for homogenisation) to the new SUEZCEMENT COMPANY plant The silos are 76 m highAfter the tensioning the extra lengths of the ropes have to b ecut and to p revent corrosion a protective cement is injectedSolution The use of 4 supporting p latforms equipp ed with 4motorised TIRFORs which move up and down 4 ribs outsidethe silo wallThese platforms have 2 func tionsa) lifting personel and material up to the working level where
they can op erate simultaneously on the left and on the rightof each rib for the placement of the prestressing ropes andtensioning jacks
b) handling the tensioning jacks by means of 2 chain-blocks(250 kg capacity) which are suspended from a trolley
running on a I-beamA metallic frame construction is needed to support theI-beam which is an integral part of the platform

Description of application
ProblemThe work consists of tensioning the prestressing wire ropes onthe inner part cutting the extra length of the ropes and injectinga protective cement to prevent corrosion
SolutionThe platforms move two by two along the ribs They have threefunctions ndash lifting personnel and materials up to the working level ndash working on the left and on the right of eac h rib for the
positionning of the prestressing ropes and tensioning jacks ndash handling of the tensioning jac ks (weig ht 1600 kg) by means
of an electric pulley block which moves along a mob ile beam(PA10718) A metallic frame construction is needed to
support the beam It is an integral part of the platformThe platforms come in from the top by means of a crane(PA1071619)
