6. Lower the rope tag line ‘sling first’ through the
GMA base and the slot in the gridmesh. It may
be necessary to squeeze the eye of the sling so
that it fits through the mesh.
7. Once lowered, the worker below should connect
a chain block or block & tackle to the sling.
They should also ensure that there is sufficient
load line chain available to be connected to the
load once the device is raised into position.
8. Haul the sling with chainblock/block & tackle
attached by pulling the rope back through
the gridmesh, such that the end of the sling
protrudes through the gridmesh and the base
of the GMA.
9. Slide the GMA beam end through the sling
and slide into position in the base, such that
the beam can rest into its operating position
within the GMA base. The chain block / block
& tackle is now set for use.
