Description / Abstract:
The scope of this SAE Recommended Practice, trailer axle alignment, is
to identify the dimensional
limits of, and a method to, establish a perpendicular relationship
between the king pin centerline
and the axle centerline at its midpoint. Various types of equipment
are commercially available
which can be used for this measurement which provides varying degrees
of accuracy, but none can be
endorsed by SAE.
The most fundamental methods of measurement will be described here,
but other equipment is
available if a greater degree of accuracy is desired.
