HYDRAULIC WINDSHIELD SYSTEM HWS
2.2.6.
HYDRAULIC ELEVATION SYSTEM HWS
The “
Hydraulic System”
is the one in charge of lifting the
HWS assemblies. It is made up of the following
elements:
CLIMBING HEAD HWS:
It
pushes the HWS set during
the hydraulic climbing process.
CYLINDER HWS:
It pushes the “Climbing Head HWS”
in the lifting process.
HYDRAULIC POWER UNIT HWS:
It pumps the
necessary oil to the “Cylinders HWS”
HOSES and COUPLER 90º:
They distribute the oil
from the “Power Unit” to the “Cylinders”.
CLIMBING HEAD HWS
These are the 2 main elements of the “Climbing Head”:
Pawl
:
It transfers the climbing load to the “Mast”. It
works in the same way the bracket, allowing the
movement of the head on the way down and
pushing the blocks on the way up.
Claws:
They are
the parts in charge of guiding the
climbing head’s movements on the mast. The
climbing head can be fixed or unfixed from the mast
only by rotating the claws.
Once connected the
“Cylinder”,
the swivel claws are
opened and inserted in the
mast’s guiding wings
. After
locking the claws with the clamping pins, the climbing
head is ready to work.
Next images show the opening and locking operations
of the claws:
Claw’s opening-closing operation:
Hold the “climbing head” from the 2 handles and then
unlock the claws (elevating the 4 Clamping pins). Finally,
open the claws rotating them from the axes. Closing
and locking operation is just the opposite.
