Decks machinery - Marine technology | Ortlinghaus
Our hydraulically released brakes and hydraulically actuated clutches and slipping clutches are installed in anchor and mooring winches as well as in towing winches for huge AHTS vessels.
On the same hand winches in davits are equipped with hydraulically released brakes or plate stacks used in customized designs.
In all these applications we either offer a safe holding function or overload protection of gear components for example.
Towing winch - Decks machinery
Hydraulical clutch | Series 021
Hydraulically actuated multi-plate clutch
Based on our friction linings, which have been tried and trusted for many years in the marine sector, clutches in this series reconcile high torque and thermal absorption rates as well as a favorable outer diameter. A high shaft diameter can also be used.
Due to their broad power spectrum, smaller sizes can be achieved with corresponding weight and cost benefits, especially in higher torque ranges. The optimized outer diameter makes shorter distances between axles possible, and in this way offers clear savings potential in the gearbox.
The hydraulic multi-plate clutch impresses with its comprehensive service friendliness. The plate pack, which is wear-free under the specified conditions, can be accessed from either side depending on the model, and ensures an easy, safe, and swift replacement of the plate pack. The special design also ensures that other components cannot fall out during replacement.
The Ortlinghaus muti-plate clutches safely accelerate even large propellers and generators. This optimal further development of our tried-and-tested technology sets today’s industry standards.
- Torque: 10,000 - 90,000 Nm
- Rotations per minute: 9,800 - 350 min-1
- Outside diameter: 90 - 1,200 mm
- Bore diameter: 35 - 500 mm
- Length: 64 - 755 mm

Slipping clutch | Series 600
Spring-applied multi-plate slipping clutch
Ortlinghaus slipping clutches are always used when external peak loads need to be absorbed and smoothed safely. They provide protection from breakage, especially for anchor winches in the marine sector. As the release torque can be set, torque is also transferred during slipping so that no uncontrolled torque transmission takes place. A reset is not required either.
Our safety clutches have proven their worth in decades of the most demanding marine use and undergo constant further development.
- Torque: 30 - 30,000 Nm
- Outside diameter: 70 - 700 mm
- Bore diameter: 12 - 220 mm
- Length: 90 - 560 mm

Davit - Decks machinery
Hydraulical brake | Series 022
Hydraulically released multi-plate brakes and plates with sintered or organic lining
The 022 series is one of the most successful Ortlinghaus products. Well over one million units are in service around the world wherever safety brakes with an extremely long service life and quality without compromise are required. In marine engineering, these multi-plate brakes are used in the deck machinery sector and as shaft brakes.
The advantage of these wet-running, hydraulically released and spring-applied multi-plate brakes is the high torques they achieve in compact dimensions. Hydraulically actuated brakes are also available as a special version.
The spring-loaded brakes are safety brakes, which automatically work in cases of pressure failure. The brakes can achieve full torque even when there is no pressure.
- Torque: 80 - 20,000 Nm
- Rotations per minute: 6,570 - 450 min-1
- Outside diameter: 83 - 910 mm
- Bore diameter: 18 - 350 mm
- Length: 59 - 360 mm

Mechnical clutch | Series 100
Mechanically actuated multi-plate clutch
They are supplied with the friction combinations steel/steel, steel/sintered lining and steel/organic lining and as a result are suitable for wet-running and dry-running, i.e. they can be used in either an open design or a closed design. Engagement and disengagement of the clutches is by means of a „sliding sleeve“ with a cam profile which is moved axially over resilient angle levers, these in turn transmit the required force to the set of plates.
A limited amount of plate wear is compensated for by the resilient bending of the levers so that the torque capable of being transmitted remains constant to a large extent and adjustment is only necessary after an extended period of time. The engaging/disengaging movement can be introduced by means of hand levers, pneumatic or hydraulic cylinders or electromechanical actuation systems.

Plate stacks
Wet-running sinter-lining plates
For dry- and wet-running clutches and brakes, Ortlinghaus is able to provide a very comprehensive range of plates. The plates and the friction surface are important functional elements in every clutch and brake, and have been developed in many different ways since the early days of clutches and brakes.
The choice of friction system depends on the application: in general, one plate with friction material works together with a counterplate of steel or cast iron. The inner and outer plates are mounted with the other drive components by lugs and slots, and the spline is in accordance with DIN 867 and DIN 5480 as well as other standards. In addition, holes in the plate for studs and special shapes in accordance with customer requirements are available.
Combined with a multi-plate clutch or brake, these plates come in a multitude of different dimensions, friction combinations, and surface patterns.
- Torque: 150 - 1,600,000 Nm
