Ship Building & Marine Hydraulic Solutions | HAOZHENG HYDRAULIC
1. Solution Overview
Marine and shipboard hydraulic systems are core power and control units for various vessels, working in humid, salty, corrosive and constantly vibrating offshore environments. They undertake critical functions including cargo handling, deck operation, vessel steering, mooring, lifting and hatch opening & closing.
Leveraging our full lineup of hydraulic pumps, cylinders, hydraulic motors, control valves and supporting parts, HAOZHENG delivers professional, corrosion-resistant and high-reliability hydraulic solutions for shipbuilding, inland waterway vessels, offshore working ships and auxiliary marine equipment. Our products are strictly optimized for marine operating conditions, featuring anti-corrosion, anti-vibration, stable output and long service life. We fully meet the strict quality standards and continuous operation requirements of the marine industry.
2. Core Industry Challenges
- Severe salt spray, high humidity and marine corrosion, easily causing component rust, seal aging and performance degradation
- Long-term continuous vibration and impact during navigation, raising risks of loose connection and oil leakage
- 24-hour non-stop operation requirement, demanding extremely high stability and low failure rate
- Limited installation space on decks and hulls, requiring compact and modular component design
- Strict marine safety regulations, high requirements for system safety, explosion-proof performance and emergency protection
- Difficult on-site maintenance at sea, calling for good part interchangeability and easy repair
