3.
If it is not possible to lift using the aforementioned
methods, rollers may be used underneath the
switchgear. Another option is to slide the cubicles over
rods (these same rods can be used to help get over the
cable trench).
4.
To handle 5 functional unit assemblies (consisting
of either coupled modules or compact assemblies
associated with modules), use lifting systems (slings,
lifting beam, etc.) with a pull angle greater than 65º and
less than 115º in order to prevent possible damage to
the cubicles during hoisting.
Use of lifting beams is required for cubicle assemblies
with control boxes. As the sole exception, slings or
chains may be used if the cubicles of the assembly
have identical height control boxes installed.
