Innovative braking systems for ship shafts – from standard solutions to custom-made special designs
What are the main tasks of a ship shaft brake system?
A ship shaft brake system primarily serves to stop and hold the propeller shaft in a controlled manner. Modern systems often also offer functions for blocking for maintenance work and for slow turning of the shaft for precise positioning, known as SBT functions.
Which types of brakes are particularly suitable for maritime use?
In the maritime sector, disc brakes are common due to their high power density. Often, spring-loaded brake calipers are used, which are pneumatically or hydraulically released and offer a fail-safe function. Manually operated brakes are also used for specific applications.
What should be considered when selecting materials for ship shaft brakes?
Due to the harsh maritime environment, high corrosion resistance is crucial. Materials such as stainless steel (e.g. 1.4571) or duplex steel (e.g. 1.4462 for higher strength) are common. The choice depends on the specific operating conditions and requirements for longevity.

Why is overload protection important for ship shaft brake systems?
An overload protection, realized through overload or slip clutches,is essential to protect the drive train from damage caused by sudden blockages (e.g. propeller strikes). These systems release when a defined torque is exceeded.
What are fail-safe brakes in shipbuilding?
Fail-safe brakes, typically spring-loaded systems,are designed to automatically engage in the event of power failure (e.g. loss of compressed air or hydraulic pressure) and safely brake or hold the shaft. This is a critical safety feature..
What benefits do torque measuring shafts provide in conjunction with brake systems?
The integration of torque measuring shafts enables continuous monitoring of braking performance and the condition of the drive train. This supports und des Zustands des Antriebsstrangs. Dies unterstützt die predictive maintenance and helps to detect failures early.
Are ship shaft brake systems also relevant for sailing boats?
Yes, special systems like the “Shaft-Lok” are designed for sailing boats. They prevent unwanted rotation of the propeller while sailing,which can improve sailing characteristics and prevent gearbox damage. Additionally, the propeller locking is often a regulatory requirement in regattas..

Introduction to ship shaft brake systems
Modern ship shaft brake systems are essential components for safety and efficiency in ship drives, not just simple stoppages. This article highlights advanced solutions from ATEK Drive Solutions for system optimization and presents technologies for specific requirements.
The requirements for ship brakes are more complex than those for land-based vehicles. A maritime braking system of this type precisely controls the rotation of the propeller shaft, which is an important aspect for the safety and functionality of a ship. It enables, for example, quick stopping in emergency situations or precise holding of position. Reliability is fundamental here.
Unlike vehicles with tire friction, ships use propeller thrust or specialized shaft braking systems to control. These systems manage the ship’s movement, especially in narrow waters or during docking. A properly sized ship shaft brake system prevents damage and secures operation. The correct design for optimal performance is crucial.Functionality and types of ship shaft brake systems
Ships do not only brake by reversing the propeller (counter-thrust) but also with specialized braking systems for ship shafts.These act directly on the propeller shaft for controlled braking. For maintenance, blocking the shaft is often necessary, which systems like blocking systems for propeller shafts can provide. Various technologies are presented.
Disc brakes are common, often with SBT functions (Stopping, Blocking, Turning) for precise positioning. Spring-loaded brakes (pneumatically/hydraulically released) ensure safety in case of pressure loss; e.g., ATEK Rietschoten Elephant Brakes up to 1,500 Nm. Manual brakes are robust and simple. The choice of type depends on operational requirements.Manufacturers and products at a glance
Established providers like SIAM RINGSPANN (e.g. DV 020 FKM brake, 2750 N clamping force, for 12.5 mm discs) and KTR (EMB-STOP SBT brake for propeller shafts) showcase the product variety for propeller shaft brakes.A precise needs analysis is crucial for selecting the appropriate braking systems WBA..
