HANDING OF LOCO WAG-9 / LOCOSHELL WAG-9
Option -1 – ‘PIT TRAVERSER’
During 20th Century, Pit Traversers were employed for handling of Loco
/ Carriages, to directly transfer, Loco from Shop Rails to Traverser.

DO NOT USE SURFACE TRAVERSER FOR HANDLING ROLLING STOCK WITH CATTLE GUARD
Surface Traverser – With suitable selection of Entrance height by proper Tongue
Length with respect to Carriage Wheel base, rolling stock with low bottom
clearance can be handled. But it is not possible to handle the rolling stock with
Cattle guard by standard Surface Traverser as seen the picture on left.

SITE CONDITIONS
To compensate Increased Entrance Height / Bottom clearance of Tongue - Unique made an
innovative solution - resolved the problem by installing Special (2 Piece) Tongue.
NOTE: For Traverser handling WAG-9 increased entrance height is not acceptable.

SITE PROBLEM of REDUCED CLEARANCE
RESOLVED BY
INSTALLATION OF TWO PIECE TONGUE /

2 PIECE TONGUE (TO HANDLE SITE CONDITIONS) WORKING EXPLAINED
If SR is at a lower level by 100 mm the angle formed between two pieces will be
175* If SR is at a higher level by 40 mm the angle formed between two pieces
will be 180+9=189*

2 Piece Tongue Explained by Photo
Front Lever (Tip end of Tongue) is hinged to Main Lever (Rear end of Tongue).
Approaching rolling stock wheel will lower the tip of front lever and as soon as wheel
rolls on this front lever, entire bottom surface of Front lever & tip of Main Lever will rest
on the SR, to bridge over the level difference between SR / TTR.

2 Piece Foldable Tongue Explained by Photo / Sketch
2 Piece Tongue with
front lever unfolded to
rest on SR before
moving Rolling Stock.
For trouble free transfer of rolling stock, temporary
packing / plates (as seen in photo on left), to be
replaced by ‘Grouted Plate’ (as shown in above
sketch), so that the front lever, when unfolded (as
shown in dotted line), partly rest on SR / Grouted
plate, during the transfer of rolling stock.
