Crane Rail

2.1.1.1

Rail Section Weight and Hardness

**************************************************************************

NOTE: Requirements for minimum length of closure

rail sections do not apply to stub rail sections

provided as part of fabricated crane rail fittings.

**************************************************************************

NOTE: All references in this section to rail

section specify per yard (135-CR) crane rail. The

135-CR section is the most common for new and

replacement portal crane track. In some work, rail

sections other than 135-CR may be required for crane

use. These include heavier rail section or, for

connection to older existing installations, use of

60 kilogram (132 pound) 132 pound or other railroad

rail may be specified. Make changes where rail

sections are required that are different than the

135-CR.

**************************************************************************

AREMA Manual and ASTM A 1. Rails shall be [664] [_____] kg per meter([135]

[_____] pounds per yard) [135] [_____] pounds per yard in weight and shall

be control-cooled, [fully heat-treated,] [321 to 388] [250 minimum] Brinell

hardness carbon steel referred to herein as [135-CR] [_____]. Crane rail

hardness shall not exceed crane wheel Brinell hardness of [388] [_____].

Provide standard 12 m (39 foot) 39 foot rail lengths except for closure

rails. Provide closure rails in one or two sections as long as practical,

but in no case shall any piece be less than 4 m (13 feet) 13 feet long.

2.1.1.2

Metallurgical Composition

The chemical composition of crane rail steel shall be within the following

limits:

a.

Carbon, percent 0.67 to 0.82

b.

Manganese, percent 0.60 to 1.00

c.

Phosphorus, percent 0.04 maximum

d.

Silicon, percent 0.10 to 0.23

e.

Sulfur, percent 0.04 maximum

2.1.2

Joint Bars

ASTM A 49 and AREMA Manual, Chapter 4. Provide heat-treated carbon steel

six-hole joint bars sized to fit the rail section.

2.1.3

Track Bolts, Nuts, and Washers

AREMA Manual, Chapter 4.

Provide track bolts not less than 23 mm one inch

in diameter.
