2. Assembling of the hydraulic cylinders
2.1 The cylinder
The cylinder serial number is on a sticker on the cylinder
head on the same side where the rupture valve is
assembled. This number appears also on the identification
sticker together with the remaining data of the cylinder (see
drawing n. 2).

Hydraulic cylinders
Operating instructions
Before storing, check that the protection packaging is in
a perfect state of preservation.
After having positioned the cylinders on proper supports,
block them in a way that they can not fall.
If cylinders in one piece have to be stored for a long time,
it is better to fill them with anti-corrosive oil. Since the oil
volume increases or decreases according to the
temperature, it is better not to fill the cylinders
completely.
If cylinders in two pieces have to be stored for a long time,
check that the flanges closing the joint close hermetically
and that the rods are well greased. Keep both the closing
flanges and the rod which comes out from the cylinder
well covered with grease.
Before putting the installation into action, replace the oil
used for the filling up and remove the excessive grease.
All the cylinders, both those in one piece and those in two
pieces, are tested in the factory at two levels of pressure
to guarantee the sealing of the seals and the sealing of the
welding.
The oil used for tests is then taken out of the cylinder. The
small quantity which remains inside acts as a protection
against rust for a long period of time. If the cylinders
remain on the site for a long time, it is better to control
the state of preservation of the rod, cleaning and
polishing it, if necessary. For long periods of storage see
point 2.2 in the operating instructions manual for the
hydraulic components.
The oil inlet (and therefore the rupture valve) can be at the
top or at the bottom; this data has to be decided when
ordering.
The rupture valve, assembled directly on the cylinder, can
be oriented in four directions with intervals of 90° each.
If in the lift shaft brickwork, painting or welding has to be
carried out, protect the cylinder head with grease and
clothes. Clean carefully after having finished the work
before putting the installation in action.
The cylinder has to be assembled perfectly perpendicular.
When the rod has reached its max. length out of the
cylinder it has to be perfectly parallel to the guides.
All the cylinders have a line elbow fitting on the head.
This fitting allows the collection of the oil lost by the
cylinder, it has to be screwed in the proper threaded hole
on the highest part of the cylinder and then connected
through a PVC pipe to a small tank for the oil recovery. In
this way the oil loss can always be detected.
