2- LOADING - UNLOADING - TRANSPORTING
Loading, unloading and transporting methods of the MMMH type cubicles are shown below:
Cubicles can be carried either way as shown in the the pictures below. In addition, forklift is usually
used to unload the cubicles from the truck and transport them to the assembly site.
2.1 TRANSPORTATING WITH FORKLIFT
Pipe Transporting is used to line up and dock the cubicles. Never use Cranks while transporting the cubicles.
2.2 TRANSPORTING OVER THE PIPE

Cubicles can be transported with
the help of sling lifting by means
of a crane. Usually it is used while
unloading the cubicles from the
truck.

In accordance with the single line diagram of the facility, combine the square-shaped holes of the cubicles side by
side using M8x20 bolts.
1. According to the “3.3- CUBICLE’S PLACEMENT” article stated
above, remove the upper cover plate of the connected
cubicles.
2. Connect the main busbars shipped with the cubicles to the
main bus terminal using eld regulators and tighten the bolts
with 50Nm torque.
3. Wipe the insulators and solid insulation materials with a dry
clean cloth.
4. Assemble the upper cover plate.
IMPORTANT WARNING: If the surface
on which the cubicles will be mounted
is not at, the cubicles’ covers may not
be tted properly and also problems
may be caused in the main busbar
connection.
