DIMENSIONS AND TOLERANCES FORHOT ROLLED TRACK SHOE SECTIONS

PART 2 SECTION TS HI

0 FOREWORD

0.1 This Indian Standard ( Part 2 ) was adopted by the IndianStandards Institution on 20 December 1985, after the draft finalized bythe Structural Sections Sectional Committee had been approved by theStructural and Metal Division Council.

0.2 The track shoe sections form an important component of the earthmoving equipment and are subjected to heavy wear and tear duringusage. There are several types of track shoe sections used in themanufacture of earth moving equipment. This standard which is secondin series covers section meant for extreme service conditions and lays

down the dimensions and tolerances applicable to the same. Part 1 ofthe standard covered TS-Ll type of shoe sections.

0.3 In this standard the recommendations for material are given inAppendix A to give guidelines to the manufacturers of track shoesections. It is not intended to be mandatory and is given as a source ofinformation based on the present experience of manufacturers and usersin the country to assist the development and use of these sections.

0.4 For the purpose of deciding whether a particular requirement of this

standard is complied with, the final value, observed or calculated,expressing the result of a test or analysis, shall be rounded off in accord-ance with IS : 2-1960*. The number of significant places retained in therounded off value should be the same as that of the specified value inthis standard.

1. SCOPE

1.1 This standard ( Part 2 ) covers dimensions, dimensional tolerancesand mass of hot rolled track shoe section TS-Hl meant for extremeservice conditions.

*Rules for rounding off numerical values ( rcuised ).

8. LENGTH

8.1 Length of shoe sections shall be as agreed to between the purchaserand the supplier.

8.2 Cutting tolerance on length shall be las agreed to between thepurchaser and the supplier.

9. SURFACE QUALITY

9.0 General - The provisions on surface quality given in 9.1 are to beused as an exception and not as a rule. The purchaser and supplier shallagree on the number of defects permissible on a length of shoe whichshall also be mutually agreed. An over-riding requirement is that surfacedefects should not in any way be detrimental to the final requirementsafter heat treatment of the component.

9.1 Laps and Seams - No laps or seams shall be permitted in theGrouser Fillet ( Radii R6 and R7 ). Maximum depth of laps or seamson the grouser sides, plate and on the-toe and heel edges shall be 1 mm.

9.2 Guide Marks - No guide marks shall be permitted in the grouserfillet ( radii R6 and R7 ). In the other locations the maximum depth ofguide marks shall be 1 mm below the normal surface.

9.3 Material defects such as piping and laminations are not permitted.Hair line cracks are not permitted on grouser fillet ( radii R6 and R7 ).However, hair line cracks up to 1 mm depth in other areas may beremoved by grinding by the supplier.

9.4 Surface defects, such as linear scars, insertions, roll scars, surfaceroughness, scale scars, jaw scars due to rolling, causing notches are notpermitted on grouser fillet ( radii R6 and R7 ) and in other areaspermitted up to 1 mm depth without grinding.
