WINCH DRIVES
This range of high-efficiency planetary units are specially designed for
winch drives. The compact PWD series is suitable for applications from
3 to 12 tons and the SLW series for line pulls in excess of 12 tons. Both
types are designed for easy integration into winch drums and offer the
ability to work in aggressive environments like for example marine
applications (with double sealing and optional epoxy paint finish).
spigots for drum fitting, and also higher levels of transmittable torque,
because the design utilises planet assemblies with 4-5 satellites .
Users of the PWD units and of the higher capacity SLW series - also
benefit from the convenience of drum fitting via bolts from the motor
side, and easy, drive-end access to the filling, level and drain plugs for
maintenance.
The planetary design of the PWD and SLW series allows engineers to
simplify winch arrangements and reduce the overall size and weight
of the assembly.
All ratings are listed according to FEM M5 with an output speed of
15 rpm. Utilising the ISO BreCal program we are able to make the
optimal selection at any torque and speed given.
Finally, the units are protected against adverse environments by “
caterpillar” seals, which have been tested over long periods in the
demanding marine sector.
The universal input version offers users the alternative of external
brakes with a backstop device, which effectively provides one-way
operation by preventing back drive through the gearbox during
hoisting, for better winch control. The combination of a universal input
and a dedicated adapter assembly enables this version to
accommodate any type of hydraulic motor. (pneumatic motors
can also be fitted.)
The robust design of the PWD gearbox means that they are
suitable for use with winches which have drum support bearings
opposite to the drive side, and also with free hanging or cantilever
drums. In either of these configurations, the PWD units provide smaller
Complementing the PWD series in the higher capacity range of
12 tons and above, is Brevini’s SLW series of winch drives. These units
are based on the Brevini “S” Series gearboxes, which feature a
revolutionary new epicyclic gear design that increases the power
available from the unit without affecting the overall weight of the
design. As a result, the “S” series provides up to 60% more torque
output than other gearbox designs of equivalent size and weight.
The SLW drives are designed for use with hydraulic motor drives
incorporating a hydraulic brake assembly .The input can also be split
to allow the facility of 2 smaller motors to drive; with flexibility in mind.
The input can also be driven via electric or pneumatic motors.
Other options include double grease-packed seals and an epoxy paint
finish, both designed to provide high levels of protection in arduous
and corrosive marine environments.
> Q U A L I T Y is an important element to satisfy your demands – on products
as well as on the service we provide. Therefore we have chosen to
TypeApprove all our standard series, slewdrives and winchdrives as well as
some complete winches. The approval is valid worldwide.
Together with our knowledge -we guarantee your safety.
Our production is ISO certified and we also have a complete quality-system
locally. This assure your interests in the best possible way. Regular audit and
changes are done as needed.
*Type-Approval acc. to Det Norske Veritas’ rules for Certification of
Lifting Appliancies, IMO SOLAS 1974 convention.

Installing the gear unit
When installing the winch unit take special care to the alignment for the centring of the structure supporting gearunit as well as the structure
supporting the contrabearing.
The structure must be rigid enough to prevent any deflection during operation.
Back Stop
All our winch drives can be provided with brake and Back Stop device if needed.
The unit rotate free one direction when no pressure are applied.
When pressure applied on the unit, is rotating free in both direction.
Always remember to specify Free Rotation of Direction when ordering. (seen from the motor side)

Lubrication
SAE J 306 ”a” gear oil at viscosity of VG 150 (SAE 90) and with EP additives is recommended for
BREVINI gear reducers.
When service temperatures vary over a wide range, synthetic oil with a VG 150 or 220 viscosity
class is recommended. This oil should have a minimum viscosity index of 165 and should contain
EP additives. In any case, the oil selected must adequately resist oil viscosity breakdown given the
particular service conditions. The scheduling of the oil changes must be consistent with the particular service conditions involved. Horizontally-mounted gearboxes must be filled half-full. After
a short period of operation, a visual check must be made of the oil level. Under continuous operating conditions, the working temperature must not exceed 90°C. In application where high
speed and hig power are required, please contact BREVINI Eng. Service Dept. for ass.
Oil Changes
The first lube oil change must be made between 50 and 100 hours of service. Subsequent oil
changes must be made after 2.500 hours of service time or at least once every 12 month.
However, the scheduling of oil changes should be in relationship with the actual operating conditions. No sludge should be permitted to accumulate in the unit, and oil changes should be
made while the gearbox is warm. The oil level should be checked at least once a month. If the
gearbox oil level decreases by more than 10%, the unit should be carefully inspected for leakage.
Different types of oil should not be mixed even if they have the same trademark. It is especially
important to avoid mixing mineral oil with synthetic oil.
