Introduction
The document introduces the HYS 150, a compact spring-applied actuator developed by HANNING & KAHL. It is part of the HYS 1xx series and is designed for use on high-speed motor shafts.

Specifications
The HYS 150 is a floating-mounted brake caliper that transfers actuator force directly to the brake disc via a lever. It features a spring-actuator unit with activation hydraulics and mechanics, including two independent hydraulic circuits: a passive braking circuit for safety and parking, and an emergency release circuit. Additional features include an automatic slack adjuster and a mechanical emergency release device.

Technical Data

• Clamping force (passive): 12-18 kN for a brake disc width of 35 mm
• Brake disc diameter: Up to 350 mm
• Temperature range: -25°C to +50°C
• Weight: Approximately 16 kg

Hydraulic Power Unit HZY-K160-PR
The HZY-K160-PR is a compact and lighter hydraulic power unit, offering the same functionality with a 20% weight reduction compared to previous models. It is designed for installation in bogie or wagon bodies.

Technical Data

• Installation space: 160 x 168 x 350 mm
• Regulating function: Proportional/stepped, emergency braking function
• Pressure range: 100 bar
• Weight: Approximately 15 kg

Design and Testing
The development process utilized modern tools such as 3D-CAD and FEM calculation programs, ensuring product reliability through extensive type tests.
