QRail Heavy and Standard rails can be spliced into a longer unit by means of
the QRail External QSplice, (Image 2.4.10-2). The bonding splice joins the two
rail segments mechanically and electrically.
The External QSplice uses two stainless steel bolts – one for each rail –
which, when tightened to the specified torque of 10-12 -lbf, pierce any
painted coating or aluminum oxide layer on the rails and embed in the rails
being joined. This forms a conductive path from the rails through the bolt
shas, captive square nuts, and star washers into the splice body.
Rail Bonding with External QSplice
All QRails can be spliced into longer units by means of the QRail Internal
QSplice (Image 2.4.11). The bonding splice joins the two rail segments
mechanically and electrically for the Heavy, Standard, and Light rails.
The Internal QSplice has a bonding plate that pierces any paint or aluminum
oxide layer on the rails. This forms a electrical bind from rail-to-rail through
the bonding plate. The splice body is electrically bonded through the bonding
plate and the rivet that secures the bonding plate.
