Lifting, moving and handling
2.2. Lifting and moving by crane
When lifting and moving the transformer with a crane, it
must be remembered that the lifting elements allow the
transformer to be completely suspended. These elements
are the lifting rings, which are fitted in the cover or in the
top part of the sides of the tank (depending on the weight
of the transformer) and identified for this purpose (e.g.
painted yellow). The following indications must be taken
into account when lifting the transformer:
• Use the eye bolts in the cover or top of the sides of the
transformer tank to lift the transformer with a crane,
maintaining a horizontal position at all times.
• Use proper hooks to achieve perfect vertical elevation.
• The slings on the eye bolts must form a minimum angle
of 60º with the transformer’s horizontal.
• The slings must not rub or damage the bushings or
other accessories.
Risk of death by crushing and damage to the
transformer or to the installation.
• NEVER use transformer cooling elements such as fins
or radiators as lifting elements. RISK of severe injury
and damage to the transformer.
