EXECUTION
3.1
WORKMANSHIP
Handle fittings, rails, and accessories to avoid kinking or other damage.
Maintain tracks in proper grade, alignment, curvature, and gage.
3.2
INSTALLATION OF CRANE TRACK AND FITTINGS
3.2.1
Crane Rails
Install crane rails to the alignment indicated. Install rails atop
continuous steel base plates with anchor bolts and rail clips. Do not bend
rail in the field, but preform rail to the required radii in a plant prior
to installation. [The entire curved layout shall be assembled with all
pieces match-marked.] Completely lay out and mark in the field and have
approved by the Contracting Officer before any portion of crane rail
alignment is installed. Tolerances shall be as follows:
a.
Horizontal alignment: Place rails within plus or minus 6 mm (1/4
inch) 1/4 inch of the designed rail centerline alignment indicated.
b.
Crane track gage: Provide track gage between railheads within
plus or minus 12 mm (1/2 inch) 1/2 inch of the design gage
indicated. Crane rail gage is measured from centerline of rail to
centerline of rail.
c.
Vertical alignment: Place top of rails within plus or minus 3 mm
(1/8 inch) 1/8 inch of the designed rail elevation indicated.
d.
Cross-level elevation: Elevation differences between rails shall
not exceed 3 mm (1/8 inch) 1/8 inch.
**************************************************************************
NOTE: Regarding the text below, use Section 05650,
"Railroad Track and Accessories" and AREMA Manual
and PTWP for standard gage railroad track
intersecting with crane tracks. Provide
specification for guardrails as required opposite
rigid frogs for use by standard gage wheels. Where
guardrail flangeway is for use by crane wheels,
provide adequate flangeway width or flare. For a
railroad in dual gage with crane track, add
references as required for half ties or rail on
grade beam foundation.
