ATEK Drive Solutions

Innovative shaft brakes for ships

In shipbuilding, one element is fundamental: safety and control in every situation. Whether luxury yacht, naval ship, research vessel, or submarine – modern ships place high demands on technology, reliability, and ease of maintenance. One essential component is shaft brakes, which ensure safety with their diverse functions and increase efficiency on board. Even more powerful today is what emerges from shared expertise:

Through the merger of ATEK Antriebstechnik Willi Glapiak with the renowned Deutsche van Rietschoten & Houwens into ATEK Drive Solutions in 2024, expertise, experience, and innovative power are combined for the development and manufacturing of custom shaft brake solutions for all types of ships and applications.

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 you how shaft brakes “Made in Germany” fit your ship vision and what to consider in selection and installation.

1. Custom ATEK Elephant Brakes: What distinguishes the solutions

Every ship presents its own challenges for safety: offshore yachts, research vessels, or fishing protection boats operate in extreme weather conditions, demand absolute reliability – and maximum control over drive and drive components. This is where tailored shaft brakes from ATEK come into play. Everything from one source – from the initial design to planning and manufacturing to maintenance, adjustment, and service.

The advantages of these custom solutions:

  • Safe blocking of shafts and propellers
  • No impairment when maneuvering, especially with sailing vessels
  • Securing movable parts during maintenance, repair work, and diver operations
  • Increased safety during steering maneuvers and when braking the propeller shaft
  • Compliance with country-specific requirements of international classification societies

Always on the “latest technology,” through:

  • Use of selected, corrosion-resistant materials, especially saltwater-resistant.
  • Surface treatment and coatings up to the “Highest Yacht Standard”
  • Modular systems
  • High precision in design, calculation, and construction
  • Specialized expertise in hydraulics, control, wiring, and piping

2. What makes the ATEK Elephant Brake so special?

After the merger of the two companies and the renaming to ATEK Drive Solutions, full energy for the development and realization of complete shaft brake systems for ships is bundled in Rellingen, Schleswig-Holstein. The delivery times are short and far below the market average. Furthermore, ATEK Elephant Brakes are available both as individual components and as fully prefabricated systems.

The most important functions

The classic shaft brake systems combine three basic functions, Turning, Locking & Braking:

  • Turning, rotating the shaft at low speed, such as during harbor maneuvers, disassembled gearboxes, controlled assembly or maintenance.
  • Locking, blocking the shaft for the safe execution of maintenance work or to prevent flow-induced rotation at rest.
  • Braking, quick, controlled deceleration of the shaft, support during the steering process, improvement of maneuverability

These functionalities can be combined and expanded according to customer requirements. ATEK Drive Solutions provides solutions ranging from simple and cost-efficient to highly complex premium systems with extensive monitoring and remote control.

Turnkey service

From the idea to commissioning: You receive system solutions that are precisely tailored to your needs. The service includes steel construction and complex piping as well as the design of hydraulic aggregates, control technology, on-site assembly, or painting according to individual color and quality standards.

3. Quality, safety, and durability: The benefits in detail

Extreme marine operation imposes the highest demands on technology and materials. The Elephant Brakes from ATEK Drive Solutions impress with:

  • Robust, corrosion-resistant materials and surface treatments (heat, frost, saltwater)
  • Custom coatings
  • High braking and blocking moments (up to 900 kNm possible)
  • Individual disc designs: smooth or toothed, split/unpartitioned, with hubs for radial mounting, with holes or external toothing depending on the application
  • Split designs allow for quick assembly and disassembly in confined spaces
  • Comprehensive certifications (including DNV GL, Bureau Veritas, Lloyd’s Register of Shipping)
  • Sensor monitoring and status displays ensure maximum operational safety

Moreover, customers benefit from short delivery times due to optimized processes and inventory management. The systems can be ordered as individual parts for easy on-site assembly – perfect for shipyards looking for flexible integration solutions.
