roof frame.
Switchgear ready for lifting: lifting hooks installed
Lifting dimensions and angle
When lifting using a crane, proceed as follows:
a) Fit lifting ropes of an appropriate load capacity
with spring catches.
b) Keep an angle of at least 60° between the
horizontal plane and the ropes leading to the
crane hook.
If a crane is available, lifting can be done by using
the lifting hooks which are delivered separately. The
lifting procedure, including how to install the lifting
hooks, is illustrated on the right.
NOTE
It is also possible to move units on a flat floor to
the installation site by using rolling tubes. The
rolling tube dimensions should be about 1 m in
length and 20-25 mm in diameter
