Introduction
2.6 Tensile Model
Generally speaking, the same requirements and suggestions applying to the
compression model force gauge also apply to the tensile unit, shown in
Figure 2.3 . The
main exception, of course, is that on the tensile model, load is applied through the use
of special end rod bearings.
Figure 2.3 Tensile model with adapters and shackles
These bearings are available for all tensile models as standard equipment. They are a
perfect fit and without any side play. Bearing pins can be machined from drill rod to suit
your particular test plan. Remember that if you require a special adapter of some kind
in place of these bearings, be sure that such adapters are self-aligning so that applied
force is always able to assume a vertical line.
CAUTION: Because there is the possibility that in service the ball-socket
connectors can become unscrewed from the beam, the operator should check
these parts at intervals to make sure that some of the threaded shank is
ALWAYS showing on the inside of the “U” shaped beam. If it is not showing, no
further loads should be applied until the connector is screwed down to its
normal position.
