Marine Cranes

Flodraulic designs and manufactures Hydraulic Power Units (HPU) and advanced hydraulic control systems specifically developed for marine crane applications, ensuring reliability, safety and high performance in demanding offshore and marine environments.

Our hydraulic solutions are engineered to support the main movements of marine cranes, providing precise control and stable operation even under heavy loads and harsh operating conditions.

In particular, we design and supply:

HPU for marine crane movement and rotation control
Hydraulic power units driven by electric or endothermic engines
Rotation control systems
Cylinder movement control systems

All our systems can be treated with specific painting cycles for marine environments, ensuring high resistance to corrosion, salt exposure and severe weather conditions.

Flodraulic can also supply hydraulic installations approved by major international classification societies, including DNV, ABS, Bureau Veritas, RINA, Lloyd’s Register and RMRS, ensuring full compliance with international marine standards.

In addition, we are able to provide high-capacity proportional control valves for applications requiring precise hydraulic regulation and high flow rates.

For installations operating in hazardous environments, Flodraulic can also supply ATEX-certified equipment, ensuring safety and compliance with regulations for potentially explosive atmospheres.
