Marine Electric Slewing Crane
Application
A marine electric slewing crane is a versatile lifting solution powered by an electric motor, capable of rotating 360° around its central axis for precise load positioning. These cranes are widely used in construction, manufacturing, and industrial operations requiring heavy load handling. Mounted on a sturdy pedestal base, they support various attachments (hooks, grabs, buckets) for diverse material handling needs.
