JHS-RBA-75

Part # VA012721

The JHS-RBA-75 is a hydraulically actuated caliper brake designed for demanding rotor braking applications in modern wind turbines. Developed on a proven brake architecture and optimized for project-specific requirements, it combines high braking performance, structural robustness, and reliable operation under extreme environmental conditions.

Featuring a split high-strength cast iron caliper design and dual brake pads, the brake delivers efficient force transmission and consistent braking performance. The hydraulic piston system generates the required clamping force to safely stop or hold the rotor, ensuring maximum operational safety and turbine availability.

The brake has been validated through comprehensive finite element analysis covering calipers, brake pads, pistons, bolted joints, and all critical interfaces. This verification confirms sufficient structural integrity and safety margins under worst-case load conditions.

  • Hydraulically actuated rotor brake for wind turbine applications
  • Proven and robust split-caliper design
  • High-strength cast iron housing
  • Reliable force transmission through dual-piston arrangement
  • Validated for extreme operational loads
  • Optimized for series production and cost efficiency
