300 - Planetary steering gears for marine applications

Intended for pipelayers

300 - Planetary steering gears for marine applications, Planetary Drives

The 300 series of planetary gearboxes is composed of 20 finely spaced frame sizes with torque capacity from 1000 to 1.100.000 Nm.
They are suitable for high torque and/or high power applications. In continuous high power applications it is possible a combination with HDO/HDP series, with or without oil cooling device. The execution with male shaft is provided with strong bearings with high radial load capacity.

The modular design allows for several configurations, including:
-single stage or multiple stages (up to 4 or 5 gear steps)
-right angled or in-line
-flange mounted or shaft mounted installation
-male solid or hollow output shaft
-high speed input shaft or motor adaptor, both hydraulic and electric motor
- failsafe multidisc brake, spring applied and hydraulically released
-output fittings on demand, like pinion, coupling, flange etc -ATEX conformity
