Marine Crane Frame: the "flexible and stable installation code" in wind and waves
Classification:
Product Introduction
On the turbulent front lines of marine engineering, underwater acoustic array deployment, wind turbine foundation module transfer, and breakwater component placement... every transition from surface to underwater is a battle against force 3-5 winds and waves, salt spray corrosion, and ocean currents. Traditional rigid lifting devices present pain points such as "shake risk," "equipment scratches," and "positioning deviation." However, the offshore-specific lifting frame, with its rigid-flexible combination of "frame load-bearing + sling load-relieving," tames the chaos of offshore lifting.
1. A "Rigid and Flexible" Sea-Resistant Structure
▶ Yellow Frame: Marine-Grade "Load-Bearing Core"
Welded from marine-grade corrosion-resistant steel (or lightweight alloy), the surface is sprayed with a fluorocarbon coating and cathodic protection, offering a salt spray corrosion resistance life of over 15 years.
Built-in buoyancy units (hollow tube design) compensate for the underwater buoyancy differences of the hoisted object, reducing the crane load by 30% and providing greater stability in wind and waves.
▶ Green Slings: Flexible "Load-Removing Net"
Material: Ultra-High Molecular Weight Polyethylene (UHMWPE) with UV-resistant coating, 10 times stronger than steel, resistant to seawater and biofouling.
Design: 32 slings are equally spaced (≤1 mm tolerance) to evenly distribute the load. They utilize 15% elastic deformation to absorb surge impacts, and the hoisting swing amplitude is compressed to ±5°. II. "Precise Positioning" for Ocean Scenarios
→ Marine Scientific Research: "Seamless Splicing" of Acoustic Arrays
When hoisting underwater acoustic monitoring modules (each weighing 1-2 tons), the hoist frame uses underwater laser positioning and synchronized tension adjustment of multiple slings to achieve module docking deviation of ≤10 mm, facilitating the rapid construction of an ocean acoustic field monitoring network.
→ Offshore Wind Power: "Wind-Wave Stable Connection" of Foundation Modules
Handling 50-ton prefabricated wind turbine foundation components in force 8 winds and waves. The frame's torsion resistance and sling load relief lock the hoisting tilt to ≤1°, breaking through the "window period" and eliminating the need for weather-dependent offshore construction.
→ Breakwater Construction: "Seamless Depositioning" of Concrete Blocks
Handling 200-ton breakwater concrete modules. Flexible slings adhere to the surface to protect the structure, while the frame maintains a horizontal position. A placement error of ≤5 cm ensures seamless wave resistance for the breakwater.
