Transport
3.2. Transport agents
All agents, companies and personnel involved in
transformer transport and handling tasks must demonstrate
due preparation, training, procedures and experience
in transporting heavy equipment which is sensitive to
damage from violent events during transport, as well as
having accreditations and aptitude certificates for driving
the means of transport used.
3.3. Selecting the route for road transport
The route chosen for road transport must be the one with
the best conditions for transporting heavy loads which are
sensitive to damage from impacts, shaking, vibrations and
accelerations.
Routes that reduce the effects of accelerations, vibrations,
impacts and shaking caused by winding roads, changes of
gradient and the camber of the road should take precedence
over shortest distance.
As far as possible, priority should be given to the highest
category of motorways with minimum slope, maximum
linearity and best road surface condition.
The transformers are prepared for flat, paved road transport
without significant potholes.
On stretches of rough roads, the transport speed must be
reduced to ensure that the load does not suffer sudden
accelerations and decelerations.
In any case, the current traffic and transport regulations
in each transit country must be abided by.
If the transformer's transport will include sections
of roads or routes off paved roads, with normal
conditions, the customer must inform
Ormazabal
of this with the order. After this is informed, the best
solution for transport must be decided between the
customer and
Ormazabal
.
3.4. Checking impact detectors
Ormazabal
reserves the right to fit impact detectors (or ask
for them to be fitted) in its transformers in order to provide
evidence of events that may cause damage to the machine
during transport.
In accordance with
IEC 60076-1
in section
5.7.4.2
Acceleration during transport
, the transformers referred to
in this manual are designed and constructed to withstand
accelerations of at least 1g in all directions (in addition
to the vertical acceleration of gravity) without damage.
If the transport is not managed by
Ormazabal
, and does not
fall within the scope of its responsibility, and accelerations
greater than 1g are expected during transport, the
accelerations and frequencies must be defined in the offer
request and the transformer must be designed according
to these values.
Ormazabal
is not responsible for damage during transport
under transport conditions that exceed the values defined
in the standard or those specified when the offer and/or
order of the product are requested.
3.5. Liability
Ormazabal
reserves the right to not be liable for any
damage caused when transporting and handling its product
if the conditions described in this general instructions
manual are not met.
