Niigata Propulsion System Z-Peller

-----~

Reliable and durable 360 degrees steerable azimuth type thruster units make sure;

- Giving thrust power: Up to 76tons Bollard Pull ahead

- Skewed Kaplan type Propeller: Low vibration and less cavitation

- Designed for easy and friendly maintenance: Complete unit with under section can be lifted up at

maintenance and repair without dry-docking.

- Easy installation: All necessary equipment, like cooler pumps and hydraulic unit possible to mount

on Z-peller bed.

.___ _____ _ _ . ___-"'L____________ _________Main Diesel En ine Robust structure heavy duty continuous operation main diesel engines are coupled with Niigata

Z-Pellers;

- Medium speed, 4 stork main propulsion engine.

- Out put power for Z-Peller application: Up to 2,206kW

- Complied with IMO NOx regulation (Annex. VI of the MARPOL 73 1 78)

Geisli!lger coupling_______ Niigata - Gesislinger coupling surely provides power transmission from main engine. Steel parts

power train is;

- High damping factor

- Long service life

- Lower weight, small sizing

- No aging

- Low wear and tear

lfydraulic clutch Multiple - disc plate wet sump type clutch to be built on Z-peller unit upper section which having

proven design by Hitachi Nico Transmission under Niigata technology.

Unique philosophy on the slipping clutch control;

- Idle slipping clutch control system

- Dual modulation clutch slipping control system

Shaftin s In addition to Niigata Propulsion System, following items are included;

- Cardan shaft (Double cross joint with spline shaft Universal Joints)

- Forged steel, keyless type Intermediate shafts

- Cylindrical roller type, forced lubrication Intermediate shaft bearing

Remote control System Tailor-made Niigata Remote Control System is designed to make sure optimized controlling Niigata

Z-peller Propulsion System. The control system is managed CPU and support operations by basic

control handles:

- GS Lever

- UNI Lever

- S-CON lever

Nii ata Z-Peller - In Fire Fighting vessels On the Fire -Fighting vessels, Niigata Propulsion System have been engaging the work as prime

mover for transfer the power to running Fire-Fighting equipment, and gelling thrust power as the

same time through unique own design slipping clutch system (Dual modulation clutch). Niigata

Remote Control System provides the selection Fi-Fi mode and main engine, dual modulation clutch

and Z-peller are under this control remotely.
