The caliper type SHD7 is a safety single-spring hydraulical caliper designed
for high speed shaft drives of wind turbines.

This caliper delivers high energy braking and is designed to be installed
directly onto the drive line gear box.

It delivers a high braking force for fail-safe use and offers also an optional
positive braking for starting use (SHD7E).

Wear Adjustment and Centering System (WACS) allows automatic air
gap centering and self-wear compensation, for easy maintenance and
reduced costs.
