Manufacturer profiles associated with Port Tug.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to directory reference data, the bollard pull typically ranges from 40 to 70 kN under standardized conditions. However, actual values depend on the specific model and configuration, so it is essential to verify with the legal manufacturer or supplier.
Port tugs commonly use Z-drive azimuth thrusters, Voith-Schneider propellers, or conventional propellers with Kort nozzles. The propulsion type listed in the directory is Z-drive, which enables 360-degree thrust for enhanced maneuverability.
The directory lists high-strength steel and marine-grade aluminum alloys as materials on file. These materials provide structural strength and corrosion resistance, but specific grades and applications should be confirmed with the manufacturer.
The directory lists CCS (China Classification Society) as a reference classification, subject to compliance with CCS rules. However, classification requirements may vary by jurisdiction and operational needs, so it is important to verify with relevant authorities and the manufacturer.
