The Kinloc Bolt:
Value Added thanks to Customized Solutions
At the end of 2014, in association with a number of customers, DSI determined that there was a need for a higher
capacity bolt that basically replicated the performance of an inflated bolt but without the complexity surrounding
installation. The Kinloc Bolt System is a mechanically operated, point anchoring friction bolt.
The DSI patented system permits anchor
installation using standard equipment.
Installation is fast and ensures immediate,
high load-bearing capacity.
In addition to the load transfer capacity of the
friction bolt, a high capacity rock bolt down
the middle of the friction bolt acts as a point
anchored bolt. This delivers a very “stiff”
system with high shear strength.

During initial testing in late 2014, DSI adapted
its existing load testing equipment to manage
the higher capacity achieved by the Kinloc
Bolt.
A customer in Western Australia was so
convinced by the product that he moved
from the trial to a full conversion to the new
Kinloc System on their drives shortly after
the testing phase had started.
Since then, DSI has continuously developed
the Kinloc Bolt in close cooperation with its
customers so that the system now offers
additional features and benefits. One of these
features relates to a retention device for the
inner bar of the Kinloc Bolt that is now part
of the system. In the event of the inner bar
breaking due to excessive load or shear, the bar
cannot fall out of the roof with the plate thanks
to the standard ECS (Event Capture System).
