If the bushing needs to be prepared specially (e.g. with a draw lead bolt or detachable
conductor bolt, or if an electrode needs to be installed), the bushing must be put down on
bearing supports for preparation.

The other lifting device is fixed to the head
on the bushing.
One lifting device (e.g. crane)
(If only one lifting device is available)
The lifting device is fixed both on the flange
and on the head of the bushing.
One lifting device (e.g. crane) +
mechanic
(Applies only to small bushings having a
weight < 50 kg)
The lifting device is fixed to the head on the
bushing.
The mechanic guides the bushing at the
