Innovative Shaft Brakes for Ships
In shipbuilding, one factor is essential: safety and control in every situation. Whether luxury yacht, naval vessel, research ship, or submarine—modern ships place high demands on technology, reliability, and ease of maintenance. Shaft brakes for ships are a crucial component, offering a wide range of functions that ensure safety and enhance onboard efficiency. Today, collaborative expertise leads to even greater performance: With the merger of ATEK Antriebstechnik Willi Glapiak and the renowned Deutsche van Rietschoten & Houwens to form ATEK Drive Solutions in 2024, expertise, experience, and innovative power are now united for the development and production of custom shaft brake solutions for ships of all types and purposes.
In this blog article, you will learn why the Elephant Brakes from ATEK Drive Solutions are the first choice in the maritime world. We will show how “Made in Germany” shaft brakes for ships can suit your ship vision and what to consider when selecting and installing them.
1. Custom-Built ATEK Elephant Brakes: Distinctive Solutions
Every ship brings unique safety challenges: ocean-going yachts, research vessels, or fisheries protection boats operate in extreme climatic conditions, requiring absolute reliability and maximum control over drive and propulsion components. This is where customized shaft brakes for ships from ATEK come into play—all from a single source, from the initial draft through planning and production to maintenance, retrofitting, and service.
Key advantages of these tailor-made solutions:
- Safe locking of shafts and propellers
- No interference with maneuvering, especially for sailing vessels
- Securing moving parts during maintenance, servicing, or diving operations
- Increased safety during reversing maneuvers and while stopping the propeller shaft
- Compliance with country-specific requirements of international classification societies
Always “state of the art,” achieved by:
- Use of selected, corrosion-resistant, highly seawater-resistant materials
- Surface treatment and coatings up to the “Highest Yacht Standard”
- Modular system architecture
- High-precision design, calculation, and engineering
- Specialized expertise in hydraulics, controls, wiring, and piping
2. What Makes the ATEK Elephant Brake Unique?
After the merger and rebranding to ATEK Drive Solutions, all resources for the development and implementation of complete shaft brakes for ships are now concentrated in Rellingen, Schleswig-Holstein. Delivery times are short, well below the market average. Furthermore, ATEK Elephant Brakes are available both as individual components and as fully pre-assembled systems.
Core Functions
Classic shaft brake systems combine three basic functions: Turning, Locking & Braking:
- Turning: Rotating the shaft at low speed, e.g., during harbor maneuvers, disengaged gearboxes, controlled assembly, or maintenance.
- Locking: Locking the shaft to safely perform maintenance work or to prevent rotation due to current while stationary.
- Braking: Rapid, controlled stopping of the shaft, aiding in reversing maneuvers, and improving maneuverability.
These functionalities can be combined and extended according to customer requirements. ATEK Drive Solutions offers solutions ranging from simple and cost-efficient to highly complex premium systems with extensive monitoring and remote control.
Turnkey Service
From idea to commissioning: you receive system solutions tailored precisely to your requirements. The service encompasses all aspects, from steel construction and complex piping to hydraulic power unit design, control technology, on-site installation, and coating to customer-specific color and quality standards.
3. Quality, Safety, and Durability: The Advantages in Detail
Extreme marine conditions place the highest demands on technology and materials. Elephant Brakes from ATEK Drive Solutions impress with:
- Sturdy, corrosion-resistant materials and surface treatments (heat, frost, saltwater)
- Customer-specific coatings
- High braking and locking torques (up to 900 kNm possible)
- Custom disc designs: smooth or toothed, split or solid, with hubs for radial mounting, with holes or external toothing according to application
- Split designs allow quick installation and removal in spaces with limited access
- Comprehensive certifications (including DNV GL, Bureau Veritas, Lloyd’s Register of Shipping)
- Sensor monitoring and status indicators for maximum operational safety
Customers also benefit from short delivery times due to optimized processes and inventory. Shaft brakes for ships can be ordered as individual parts for easy on-site installation—ideal for shipyards seeking flexible integration solutions.
4. Practical Examples – Typical Reference Projects for Modern Shaft Brakes for Ships
To give an idea of the range of performance, here are some practical examples from recent shipbuilding projects by ATEK Drive Solutions:
| Ship Type | Braking Torque | Locking Torque | Brake Disc | Special Features |
|---|---|---|---|---|
| Research Vessel | 370 kNm | 900 kNm | Ø 1536 × 65 mm | With turning gearbox and split design |
| Luxury Yacht | 150–370 kNm | 227–900 kNm | approx. 1500 × 50 mm | “Highest Yacht Standard”, special damping |
| Naval Vessel | Up to 900 kNm | Up to 900 kNm | Custom-made | Shockproof design per BR3021 |
| Submarine | Custom | Custom | Corrosion-optimized | Extremely pressure- and seawater-resistant |
| Bow Thruster | Up to 370 kNm | As required | Modular system | Space- and weight-optimized |
Typical installed systems include: shaft brakes for ships with locking devices (e.g. 60 kNm braking torque), individual monitoring units (certified pressure switches, runtime monitoring), and a turning gearbox for moving the ship’s shaft during specific maneuvers.
