High Tensile Railway Track T-Bolt
Track bolts are used to fasten rail ends together at a joint. The
sizes of track bolts are varying with the requirements of the
section of rail. The proper diameter and length of the track bolt
can be determined by checking the applicable railway standard.
The track bolts can be classified into several types, such as,
Button head oval neck track bolt, Diamond neck track bolt, Rail
bolt NF F50-008, Fish bolt, Track bolt of Russian standard, Clip
bolt, Clamp bolt and inserted bolt for Russia, , anchor bolt,
T-bolt clamp and other special bolts, etc.
Application Criteria of Track Bolts
According to related rail standards, each joint needs to be bolted
with at least two bolts in each rail tightened to approximately 400
foot-pounds of torque which develops between 25,000, and 30, 000
pounds of tension in the bolts.
- Bolts in use have to be in the proper size and tightly in place.
- Bolts have to be installed with AREMA spring washers whereas the
nuts have to be installed against the spring washer.
- Bolts have to be installed and the nuts have to installed
alternately on the inside and outside of the rail.
- When bolts and joint bars are moved away, the joint area of the
rail and the contact surface of the joint bar have to be cleaned
and the joint bar and the bolt threads have to be lubricated.
- Safety standards require that on operation are permitted over rails
where all bolts are missing or ineffective
