the foundation.
The crawlerwas configuredwith54m
ofmainboom, 36mof derrickboom, 65
tonnes of central ballast, 150 tonnes of
slewingballast and350 tonnes of
suspendedballast. Thederrickwas
configuredwith aworking radius of 18m.
To get the bridge intoposition ready
for lifting, Riga-Mainz used twoparallel
10 axle self-propelledmodular
transporters (SPMT).With the section
inposition, two supportswere threaded
through the truss sections of the bridge
and secured, ready for the lift.
With the cross beam and rigging
equipment theLR1600/2hoisted the
bridge intoplace. The total weight of the
liftwas 402 tonnes. Riga-Mainzused two
other Liebherr cranes, anLTM1200-5.1
and anLTF1045-4.1, for set-up and
supportwork. KathrinGottschang,

600 tonne capacityLiebherr
LR1600/2 crawler crane to install a
railwaybridge inBadWimpfen,
Baden-Württemberg, Germany.
The liftwas carriedout forGerman
rail companyDeutscheBahn (DB) as part
of the expansionof the railway around
Heilbronn. Thenew steel bridgeweighed
355 tonnes andwas 40metres long.
Challenges on site included a small
working area and a limited time schedule.
To fully support theweight of the crane
during the lift, two reinforced concrete
rampswith adozen13metredeep
said, “Rigawas the only supplier tooffer a
solutionusing just one crane. The concept
suggestedbyUweLanger [Riga-Mainz
owner]was also the onlyone that included
threading the cross beam through the
bridge trusses.”
