ASSOCIATION WITH
INDIAN RAILWAYS
UNIQUE ASSOCIATION WITH RAILWAYS COMMENCED IN 1984
& UNIQUE IS NOW AN ESTABLISHED SUPPLIER OF CRANES,
TRAVERSERS & COACH WASHING PLANTS TO INDIAN RAILWAYS.
Almost a decade ago, In its drive to modernize, C.O.F.M.O.W. (Central
Organisaton Of Modernisation Of Workshop) called upon Unique to
design and supply its first Traverser & awarded the contract of a surface
type Traverser of 80 Ton capacity, installed at the Ajmer workshop of the
Indian Railways.

NOTICE THAT BRIDGE IS BUILT FROM STRUCTURAL
MEMBERS BUILT BY RIVETTING & CONNECTED BY PINS
A truss can be assembled from small easily handled and transported pieces & site can be pin
connected or bolted. Additional stresses may develop – which can be minimized by careful
realignment during assembly re-assembly

TO UNDERSTAND THE IMPORTANCE OF CONCENTRICITY OF MEMEBRS AT EACH JOINT
FOR DESIGNING TRUSS THE BASIC ASSUMPTION IS THAT ALL FORCES WILL
BE CONCENTRIC AT EVERY JOINT SO RESULTANT FORCE AT EVERY
CONNECTION IS ‘ZERO’

WHY PORTALS?
COMPONENTS OF PORTAL TRUSS STRUCTURE.
Portal consists of two column and cross beam rigidly connected, either by
bracing or by a hunched welded, to sustain bending moment at the joints.

Difficulties encountered in RE-ALIGNING THE MEMBERS FOR REASSEMBLY AT SITE OF
BOLTED STRUCTURAL MEMBERS OF TRUSS BRIDGE WERE resolved by now using welding
technology FOR BUILDING LARGE BOX GIRDERS transported TO SITE IN ONE SINGLE PIECE -
making installation work very easy ALONG WITH OTHER BENEFITs, discussed in next slide

STRUCTURAL ADVANTAGES OF BOX GIRDERS
CONSTRUCTION FOR TRAVERSER
• IMPROVED TORSIONAL RIGIDITY WITH REDUCED
CHANCES OF FATIGUE FAILURES
• WIDE TOP & BOTTOM FLANGES ALLOW LARGE
SPAN TO DEPTH RATIO, IMPROVING VISIBILITY
(CLEAR VIEW TO) / COMMUNICATION BETWEEN
OPERATOR / OPERATING PERSONNEL
• BETTER APPEARANCE
• TRANPORTATION POSSIBLE IN SINGLE PIECE
It will be interesting to notice that
TO TAKE BENFIT OF IMPROVED TORSIONAL RIGIDITY OF CLOSED BOX
CONSTRUCTION, TRUSS BRIDGE WITH SPAN > 12M ARE NOW BUILT BY HOLLOW
TUBES / LARGER SPANS BUILT BY USING FABRICATED BOX.
BOX GIRDERS CONSTRUCTION IS MORE ATTRACTIVE FOR SPANS < 30M, IN VIEW
OF BETTER APPEARANCE / CONVENIENCE IN TRANPORTATION & MINIMISED

MAIN LIMITATIONS OF TRUSSED TRAVERSERS
 HEIGHT OF DECK AT THE ENTRANCE OF TRAVERSER IS TO BE LIMITED – TO ALLOW
THE COACHES TO ENTER TRAVERSER WITHOUT INTERFERENCE WITH TRAVERSER
STRUCTURE. THIS RESULTS IN COMPARATIVELY WEAK PORTAL CROSS BEAMS / WEAK
RIGID CONNECTION BETWEEN BEAM & VERTICAL POST.
 RIGID CONNECTION OF DECK WITH BOTTOM CHORD RESULTS IN TRANSFFER OF
HEAVY BENDING MOMENT TO TRUSS (AS PORTAL COLUMN BECOMES A PART OF
TRUSS). THE LOAD GETS TRANSFFERED TO TOP CHORD AT SUPPORT POINT
 DUE TO SIZE (HEIGHT) OF TRUSSED STRUCTURE IT IS NOT POSSIBLE TO TRANSPORT
THE ASSEMBLED STRUCTURE. DURING RE-ASSEMBLY AT SITE MEMBERS MAY BE
MISALIGNED DUE TO DAMAGE (BENDS) TO TRUSS MEMBERS (WHICH ARE
COMPARATIVELY SLENDER) DURING THE TRANSIT.
THIS RESULTS IN UNPREDICTABLE ADDITIONAL STRESSES

UNICRANE TORSIONAL RIGIDITY PORTAL BOX TRAVERSER
Due to the high torsional rigidity, box girders are a very convenient
solution for Cranes and Traverser - subjected to lateral forces as a
result of acceleration, braking or bumping of on the end stop. The
advantage is associated with a higher natural frequency of torsional
vibration of the deck avoiding an interaction with the fundamental
mode corresponding to vertical vibrations (flexure mode). The risk of
flutter instabilities is thus eliminated.
Additional Torsional Load

16. UNIQUE INDUSTRIAL HANDLERS PVT.LTD.
UNICRANE WHY PORTALS FOR TRUSSED BRIDGE
LONGITUDINAL TRUSSES ARE WEAK IN LATERAL DIRECTION.
TO IMPART TORSIONAL STABILTIY AGAINST WIND / EARTHQUAKE / LATERAL LOADS
DUE TO CANTILEVER CABIN, ACCELERATION & BRAKING OF MOVING BRIDGE AND
BUMPING OF BRIDGE AGAINST END STOPS – PORTALS PROVIDED, WHEN BOTTOM
CHORD IS COMAPRATIVELY WEAK / NEAR THE SUPPORT POINT OF LATERAL FRAME.
