Brevini’s lightweight, compact slew
drive gear systems are used in the
wind power industry to deliver high
reduction ratios and torque ratings.

In the UK and worldwide it has
installed more than 70,000 pitch and
yaw drives, each of which has been
geared to provide
continuous and
reliable service for
the life of the
turbine.

The pitch system
is responsible for
controlling the angle
at which the blades
face the wind; it is vital these systems
work reliably in order for the turbines
to generate the optimum levels of
energy. Brevini’s planetary slew gear
units provide an optimal solution for
pitch drives for wind turbines up to
the largest sizes considered today.
