Port technology - Marine technology | Ortlinghaus
There is a wide variety of possible uses of brakes and overload clutches in port technology. Safety brakes are used for hoist winches or cable reeling drums in port cranes. Ortlinghaus offers products for overload protection of the winch gearboxes. Plate stacks are used in customized solutions. Parking brakes are installed in the drive of straddle carriers to keep the whole unit in a fixed position.
On ship cranes we see almost similar brake and overload clutch applications with our units in a wide torque range. Additionally ship cranes can be equipped with overload clutches to limit the side tension on the crane bow, when used during heavy sea anchoring at gas or oil platforms.

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: 500 - 150,000 Nm
- Rotations per minute: 6,570 - 450 min-1
- Outside diameter: 83 - 910 mm
- Bore diameter: 18 - 350 mm
- Length: 59 - 360 mm

Main drive in straddle carriers - Port technology
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.
