内容简介

Marine Hydraulic Slewing Crane (Product Description & Technical Parameters)


1. Product Introduction


Marine Hydraulic Slewing Crane is a heavy-duty, all-directional lifting machinery specially designed for shipboard, offshore platform, and port operations. Engineered to withstand harsh salt-spray, high-humidity, and wave-motion marine environments, this crane integrates advanced hydraulic drive, precision 360° continuous slewing, and stable luffing systems to deliver safe, efficient, and flexible load handling for cargo transfer, equipment installation, and offshore service tasks.

Built with high-strength marine-grade steel and multi-layer anti-corrosion protection (hot-dip galvanizing + marine epoxy coating + cathodic protection), our crane ensures exceptional durability and long service life in offshore conditions. It features a compact pedestal-mounted design, optimizing deck space while maintaining powerful lifting performance. The full hydraulic system enables smooth, stepless control for lifting, luffing, and slewing motions, with dual operating modes (cabin control + wireless remote control) for maximum operational flexibility.

Compliant with international classification society standards (CCS, BV, LR, DNV, RS), our marine hydraulic slewing crane is widely applied on cargo ships, workboats, offshore platforms, engineering vessels, and port terminals, providing reliable lifting solutions for both routine and heavy-duty marine operations.
