The Mono 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). Option Wear Adjustment and Centering System WACS allows to have automatic air gap centering and self-wear compensation (for easy maintenance and reduced costs).
