Indian Standard
SPECIFICATION FOR
CRANE RAIL SECTIONS
( First Revision )
0. F O R E W O R D
0.1 This Indian Standard (First Revision) was adopted by the Indian
Standards Institution on 4 June 1980, after the draft finalized by the
Structural Sections Sectional Committee had been approved by the
Structural and Metals Division Council.
0.2 This standard was first published in 1966. In this revision the
range of rail sizes has been enlarged to include some of the sections
commonly used in the industry.
0.3 A supplementary list of rail sections covering the 125 kg/m rail
(earlier designated as CR 140) a few non-metric railway rails and some
non-metric and metric crane rails which are in regular use is given in
Appendix A.
0.4 In the formulation of this standard assistance has been derived
from:
IRS-T12-64 Flat bottom railway rails, Ministry of Railways,
Government of India.
GOST 4121-76 Crane rails gosudarstvennyj komitet standartov,
Meri Izmeritel’nyh Priborov SSSR (USSR).
0.5 This edition 2.1 incorporates Amendment No. 1 (October 1983).
Side bar indicates modification of the text as the result of
incorporation of the amendment.
0.6 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
accordance with IS:2-1960*. The number of significant places
retained in the rounded off value should be the same as that of the
specified value in this standard.
1. SCOPE
1.1This standard lays down the dimensions, shape and other
requirements of crane rail sections.
*Rules for rounding off numerical values ( revised ).
3IS : 3443 - 1980
2.GENERAL REQUIREMENTS FOR THE SUPPLY OF
MATERIAL
2.1 General requirements relating to supply of material shall be as
laid down in IS : 1387-1967*.
3. DESIGNATION
3.1 Crane rail sections conforming to this standard shall be designated
by the letters ISCR followed by the head width of the rail section in
millimetres. However, the crane rail sections covered in Appendix A
shall be designated by the weight in kg/m.
3.2For shop marking and drawing office purposes, abbreviated
reference symbol CR instead of ISCR may be permitted provided
specific understanding exists between the producer, drawing office and
fabricator.
4. CHEMICAL COMPOSITION
4.1 The material when analysed in accordance with the appropriate
part of IS : 228† and its relevant parts, shall have any of the chemical
compositions on the finished product given in Table 1. The location of
sample for chemical analysis shall be as shown in Fig. 1.

5. TENSILE PROPERTIES
5.1 The tensile test specimen shall be located as shown in Fig. 1 when
tested in accordance with IS : 1608-1972‡, the steel shall have a
2minimum tensile strength of 710 MPa (72 kgf/mm ), with a minimum
elongation of 14 percent on a gauge length of 5.65 Sowhere So is the
area of cross section of the specimen in the gauge length.

6. HARDNESS
6.1 The hardness of the rail head when tested in accordance with
IS : 1500-1968* shall be not less than 200 HB.
7. SAMPLING
7.1 The number of samples to be tested for chemical analysis, tensile
properties and hardness shall be one for every 100 tonnes or part
thereof subject to a minimum of one specimen per cast.
8.DIMENSIONS, TOLERANCES AND SECTIONAL
PROPERTIES
8.1 The dimensions of crane rail sections shall be as given in Table 2.
Calculated sectional properties based on these dimensions are given in
Table 3.
8.2 The tolerances on various dimensions of crane rail sections shall be
as given in Table 4.
8.3 The dimensions of some of the rail sections commonly used in the
country are covered in Appendix A along with relevant tolerances and
sectional properties.
*Method for Brinell hardness test for steel ( first revision ).
