Regular Operation Release Handle
Cannot Release Under Load
In conventional hook systems the regular
release handle can be used to open the hooks
under load and therefore potentially drop
the boat. A requirement for the Triple5 hook
was that when the hooks are under load it is
physically impossible to use the regular
operation release handle.
Distinctly Different Release Method for
On-Load Release
Related to the requirement above is that
there needs to be a distinctly different
method of releasing the hooks in an on-load
condition. This further reduces the
possibility of an accidental mid-air
release.Multiple Deliberate Actions to
Release On-Load
To further ensure that on-load release
cannot accidentally occur through operator
error, there was a requirement for multiple
deliberate actions to release the boat under
load.
Hook is either Open Or Closed, Cannot be
Partly Open or Partly Closed
Many conventional hooks allow for the hooks
to remain in a partially open or partially
closed state. This has resulted in operators
hooking up to an incorrectly set hook. This
then leads to catastrophic consequences when
the boat falls from the hooks. A requirement
for the Triple5 hook was that the hooks are
either open or closed, they cannot remain
partially open or partly closed. The
operator will then not be able to hook up to
an incorrectly set hook. |
