Lower tie-down elements:
there are four and they are
found at the base of the transformer (Figure 2.5)

Lower transport tie-down
►
When tying the transformer down, pay attention that
the securing strap does not interfere at any time with
any of the transformer's refrigeration elements or
accessories.
►
The tie down straps should be attached to the
containers’ fastening elements on both sides of the
transformer so that they produce symmetrical tension
that is counterbalanced on both sides.
►
Do not use the connecting rods on the refrigeration
elements as securing points for transport, or for any
other similar purpose (Figure 2.6).
►
Some accessories may be removed and attached as
additional packages for transport.

Transporters
The agents, companies, and personnel involved in the task of
transporting and handling the earthing transformer must
demonstrate preparation, training, procedures, and
experience with transporting heavy equipment and with
equipment that is sensitive to damage from violent transport
events.
2.7
Route selection for road transport
Route selection for road transport must be done so that the
road selected is the one that demonstrates the best conditions
for transporting heavy loads sensitive to damage from impact,
shaking, vibrations, and accelerations.
A route that reduce the effects of accelerations, vibrations,
impacts, and shaking caused by sinuosity, changes in slope, or
the state of the road's cant must take precedence over the
shortest distance.
Routes should be avoided where there is construction or that
have slopes and priority should be given as far as possible for
higher grade interstates that have the least amount of slope,
maximum linearity, and better road conditions.
2.8
Checking the impact recorders
Ormazabal
reserves the right to accommodate impact
recorders or detectors in its transformers, which reveal events
during transport that can cause damage to the machine.
Acceleration values greater than those shown in the following
Table 2.1 are unacceptable, as taken from IEEE Standard
C57.93-2007:

Responsibility
Ormazabal

damages caused from the transport and handling of its
product when the conditions described in this document are
not met.
