SECTION 2
MOUNTING
Winch mod. MH is designed to be mounted on
vehicles frame. The winch base angles should
be securely mounted to the vehicle frame in
manner acceptable to the vehicle manufac-
turer. It is responsibility of the person(s) in-
stalling the winch to make certain that the
winch is secured to the vehicle with equiva-
lent or greater strength capscrews than VIME
Industrial used to secure the winch to the
base angles. The winch must be fitted hori-
zontally to give best lubrication and securely
mounted on a surface who resist to the winch
pulling, without having any flex within the
base and winch while in use.
IMPORTANT
Winch is built up for different model of

2.3 FLEET ANGLE
Section 2 Mounting
Winch should be mounted as close to centre
and as perpendicular as possible to the
direction of the line pull. This will keep the
wire rope fleet angle centred onto the drum as
small as possible.
DANGEROUS
If the proper fleet angle is not main-
tained, the wire rope could wind onto
one side of the drum. This could cause
failure of the winch or wire rope, result-
ing in damage, injury or death.
WARNING
A wrong or inadequate winch mounting
could damage the winch.

2.4 WINCH MOUNTING ANGLES
PICT.8
To fit the winch on vehicle chassis it should be
better mounting a frame adapter brackets
bolted to the winch base angles as close to
the gear housing (1) and clutch housing (2) as
practicable (SPAN distance) shown in pict.8.
This method would provide the greatest
strength and minimize distortion by using
frame adapter brackets not inferior to the
base angles

WARNING
Excessive gear and bushing wear, difficult
in drum freespooling, lowest winch per-
formance are usually symptoms of mis-
alignments.
IMPORTANT
At the end of winch mounting, check winch
alignment; with drum disengaged manu-
ally turn winch drum. A visual check could
be done, inspecting the distance between
drum flanges (7) and gear housing end (1)
see view A, reference (8).

Once the winch has been mounted onto
the vehicle chassis (chapter 2.2-2.3-2.4),
should be connected to the hydraulic circuit
according to the typical lay-out shown below.
If conditions where the hydraulic system has
only a winch which is used intermittently,
where ambient temperature are moderate,
16
PICT.10
and where excessive back pressure or internal
leakage are not present, a reservoir equal in
size to the flow of the system can be used.
Hose lengths should be kept as short as
possible. Sharp bends in hoses and tubing
and 90 degree fittings, should be avoided
since they increase back pressure.

WARNING
Do not exceed 100 Lt/min. If exceeded

WARNING
The relief valve (ref.4 pict.10) must be
set so the pressure supplied to the winch
doesn’t exceed the pressure rating of the
winch. If the pressure or flows exceeds
those rated for the winch, it could cause
damage to the winch, to the wire rope or
damage to property, personal injury or
death.
IMPORTANT
Hydraulic pressure or flows lowest than
those rated for the winch will result in
lower line pull or lower line speed.
WARNING
The hydraulic orbital motor mounted on
model MH needs necessarily a drain line
directly to the oil reservoir. In case of
missed or wrong drainage line cause
immediately, at the first winch start, the
hydraulic motor adapter oil seals damag-
ing and in some occasion could crack the
hydraulic motor adapter.
If the hydraulic circuit has been designed as
requested the hydraulic oil comes out from
the hydraulic orbital motor shaft, runs in the
hydraulic motor adapter (7) pict.11 and comes
back in oil reservoir ref.5 pict.10 through
drainage line (C) pict.11. If the hydraulic cir-
cuit has been designed as requested the
winch works with the lubricant oil at the level
and the hydraulic oil separeted as shown in
pict.11.

having the opportunity to be discharged
through the drainage line will damage oil seal
pict.12 or if oil seals will offer a good resis-
tance hydraulic motor adapter (7) could be
damaged too, his will determine an oil leakage
from the hydraulic motor adapter body as
shown in pict.12. In this case hydraulic oil will
come in to the gear housing. The gear housing
will be completely filled up by hydraulic oil
who will come out through the breather plug
(9).
WARNING
Do not operate with winch gear housing
completely filled up with hydraulic oil.
Hydraulic oil cannot lubricate worm gear.
Worm gear could be easily damaged.
WARNING
Winch control devices should be
positioned for safe operation of the
winch without hesitation or lost of time.

IMPORTANT
Winch control devices are at exclusive
charge of the installer, who will also
take care to place all decals, to indicate
the different winch function to avoid any
misunderstanding to the winch operator
while winching.
OIL TYPES: Mineral hydraulic oils are
recommended with anti-wear additives, type
HLP [DIN 51524 (part.2)] or HM [ISO 6743/4].
The use of different oils, hydraulic motor com-
pany must be contacted.
TEMPERATURE: When selecting hydraulic
oils , it is very important consider the
operating temperature of the hydraulic sys-
tem. Oil temperature should lie between
+30°C [+85°F] ed i +60°C [+140°F]. As a
general rule, oil life is halved for each
+8°C [+15°F] its temperature exceeds 60°C
[+140°].

VISCOSITY: The viscosity of the oil should lie
between 20 mm²/S and 75 mm²/S
[100 e 370 SUS] when the operating
temperature of the system has become
stabilized. We recommend the use of an oil
type having a viscosity of 35 mm²/S [165
SUS].
FILTERING: It is necessary to keep the level of
oil contamination at an acceptable level to
ensure problem-free operation. To maintain a
correct level of cleaning is necessary a return
filter of 40 µm absolute or 25 µm nominal. In
very dirty environments, in complex systems,
the recommended filtration is 20 µm absolute
or 10 µm nominal. In any case should refer to
the vehicle hydraulic system designer recom-
mendation where the winch will be mounted,
also about maintenance.
According to the orbital hydraulic motor
plumbing, its shaft will turns in clockwise or
counter clockwise, that’s will determine a
different winch drum rotation (pict.13).
Winch model MH is equipped with a worm
gear drive train, who doesn’t have
pre-determined and obligatory drum pulling
direction, who can be set in clockwise or
counter clockwise direction.
NOTE
If the winch is equipped with accessories
such as : Heavy-duty roller Fairlead and
Cable tensioner, these are fitted, without
any indication in the winch order, as
shown in this instruction maintenance
manual.
