30 Ton Marine A-Frame Crane

30 Ton Marine A-Frame Crane

Engineered to excel where conventional cranes fall short, the OUCO 30-Ton Marine A-Frame redefines heavy lifting for specialized maritime applications. This robust system is built to deliver unmatched stability and precision in the challenging conditions of offshore operations, from scientific research to complex industrial installations.

Superior Stability in Dynamic Conditions
Certified for a Safe Working Load (S.W.L.) of 30 tons (300 kN) at the gantry point and designed to withstand the rigors of Sea State 4, this A-frame guarantees performance when it matters most. Its unique vertical-plane operation eliminates the pendulum effect common with rotating cranes, ensuring precise control during delicate operations such as ROV launch/recovery, deep-sea equipment handling, and heavy module placement. This results in safer, more efficient operations with minimal load sway.

Optimized Design for Maximum Efficiency
With a generous 8-meter span between columns and a significant 6.5-meter lift height, the A-frame provides ample clearance for handling bulky subsea equipment. Its engineered geometry achieves a 4.5-meter offboard reach at a -30° angle, enabling extensive over-side operations without sacrificing valuable deck space. Integrated anti-sway winches (≥3-ton capacity) and hydraulic luffing cylinders work in concert to enhance control and safety during lifting tasks.

Seamless Integration and Customization
The A-frame is designed for seamless compatibility with auxiliary deck machinery. The system maintains its full 30-ton S.W.L. even when winches are positioned 10 meters away, and it features an 18-ton winch tension rating to work in unison with geological winches, CTD systems, and other critical equipment. OUCO offers comprehensive customization, including major class certifications (ABS, BV, CCS), polar-grade packages for operations down to -40°C, and hazard-environment adaptations (ATEX/API2).

Built for a Global Fleet
Ideal for research vessels, offshore support platforms, and multi-role utility ships, the OUCO A-Frame combines marine-grade durability with unparalleled versatility. By adhering to international standards like ISO 4853 and prioritizing a minimal deck footprint, OUCO delivers a cost-effective, all-weather lifting solution engineered for exacting performance in the world's most unforgiving marine environments.
