the truss connected to the base with pins the
hoist was used to aid raising the truss into
its final position, thus reducing the manual
handling element of the construction.
Exclusion zones were implemented to ensure
that the production was in full control of the
area as well as the structure and prevent-
ed people being in the area who were not
aware of the method of construction and the
safety implications associated with it.
Once in its final location the decision of
whether to use purely ballast or keeping the
motor to stabilize the truss. The decision was
easy: with the point still attached, the truss
was controlled, which removed the need to
access at height to remove the point, and
also made the de-rig easier/simpler/safer.
In addition to addressing safety in the design and production of the
rig, ESA founder and Production Director, Jim Digby required and
paid for every crew member to complete the ESA’s ESAT training
before participating in the tour.
