HANDING OF LOCO WAG-9 / LOCOSHELL WAG-9

During 20th Century, Pit Traversers were employed for handling of Loco / Carriages, to directly transfer, Loco from Shop Rails to Traverser.

HANDING OF LOCOSHELL WAG-9 / AC Coaches / LHB Coaches Option – 1 – ‘SURFACE 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.

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

HANDING OF LOCOSHELL WAG-9 / AC Coaches / LHB Coaches ‘SURFACE TRAVERSER’ – SITE CONDITIONS (PROBLEMS)

Guide Rails projecting 25 mm above Top of TR

GUIDE RAILS / BAYAREA GROUND FOUNDAT HIGHER LEVEL

SITE PROBLEM of REDUCED CLEARANCE RESOLVED BY

INSTALLATION OF TWO PIECE TONGUE / SUITABLE GRADIENT AT THE ENTRANCE

TWO PIECE FOLDABLE TONGUE

FOLDABLE TONGUE TIP WILL REST ON FLOOR WHEN UNFOLDED FOR

HANDLING ROLLING STOCK WITH SMALLER WHEELS /

LOCOS WITH SANDING PIPE Lever folded to clear obstructions.

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 PhotoFront 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 wheelrolls on this front lever, entire bottom surface of Front lever & tip of Main Lever will reston the SR, to bridge over the level difference between SR / TTR.

For trouble free transfer of rolling stock, temporarypacking / plates (as seen in photo on left), to bereplaced by ‘Grouted Plate’ (as shown in abovesketch), so that the front lever, when unfolded (asshown in dotted line), partly rest on SR / Groutedplate, during the transfer of rolling stock.
