Gantry Grab Offshore Crane

YFM Gantry Grab Offshore Crane is a heavy-duty offshore lifting equipment specifically designed for heavy-load operations on offshore ships/platforms.

As an offshore crane, the YFM Gantry Grab Offshore Crane is used in combination with a grab bucket, and is suitable for complex working conditions such as port dredging, deep-sea mineral mining, and salvage of sunken ships.

With its modular structure, ultra-high corrosion resistance, and precise grabbing ability, the offshore corrosion-resistant grab crane can stably cope with the challenges of strong wind and waves, high salt fog, and extreme loads, providing an all-weather and high-efficiency solution for marine engineering.
