Applications
Advancing intelligent manufacturing and hydraulic innovation through independent R&D.
Port & Harbor Equipment
Ports and terminals include container yards, bulk terminals, Ro-Ro areas and bonded logistics zones. Typical equipment includes heavy-duty forklifts, reach stackers, empty-container handlers, terminal tractors, dock levelers and container-handling attachments. Hydraulic cylinders drive mast lifting, steering, tilting, outrigger leveling, spreader telescoping and lock-pin actuation. For OEMs and terminal maintenance teams, the key value of port equipment hydraulic cylinders is not only lifting force, but corrosion resistance, low downtime and fast replacement based on drawings.

Key Challenges
1
High Salt-Spray Exposure
marine environments attack rod coatings and seal lips.
2
Continuous Shifts
Terminal equipment often runs 16–24h shifts, accelerating heat build-up and seal wear.
3
Heavy Shock Loads
Reach stackers and heavy forklifts handle 20–45T containers with high lifting and tilting impact.
4
Tight Installation Space
Spreaders, dock levelers and outriggers require accurate pin-to-pin dimensions and mounting angles.
5
Short Maintenance Windows
Terminal downtime is costly, so replacements must be delivered fast or reverse-engineered from used parts.
