Harbour Portal Crane Manufacturer in China | Port Portal Crane Solutions
A harbour portal crane (also known as a port portal crane, harbour gantry crane, or portal jib crane) is a heavy-duty, slewing material handling crane mounted on a gantry-type portal frame. It travels on fixed rail tracks along quaysides, bulk terminals, general cargo ports, small-to-medium-sized harbours, and inland river ports.
It is specifically engineered for efficient, versatile, and high-capacity cargo handling including:
- General cargo
- Bulk materials (coal, grain, ore, sand)
- Container handling (feeder ports & inland terminals)
- Breakbulk & project cargo
- Heavy industrial components
Unlike ship-to-shore (STS) cranes or rubber-tyred gantry cranes (RTG), the harbour portal crane offers full 360° rotation, long outreach, and a small footprint, making it one of the most flexible and cost-effective solutions for multi-purpose ports.

Key Advantages of Harbour Portal Crane / Portal Harbour Crane
360° Full Slewing Capability
Unrestricted rotation allows operators to handle cargo between ship, yard, and truck without repositioning the crane.
Dual-Purpose Operation (Hook & Grab)
Easily switch between hook, grab, and container spreader for multiple cargo handling applications.
Compact Design, Powerful Performance
Small rail gauge fits older or space-constrained ports while maintaining high lifting capacity and long outreach.
Energy-Efficient All-Digital AC Drive
Full digital AC frequency conversion with PLC control, vector frequency conversion, and energy feedback technology.
Marine-Grade Corrosion Protection
Marine-grade paint systems, sealed electrical systems, and stainless steel components ensure long service life in harsh marine environments.
