Parts of Portal Slewing Crane

A Portal Slewing Crane is mainly composed of the portal frame, slewing mechanism, boom system, trolley & hoisting system, electrical control system, and crane travelling mechanism, working together to provide efficient ship-to-shore handling capabilities.

Portal Frame (Gantry Structure): Main support structure providing stability, rigidity, and load-bearing strength.
Slewing Mechanism: Enables 360° rotation for flexible and wide-area cargo handling.
Boom System (Luffing Boom): Adjustable outreach for grab, hook, or spreader work with smooth luffing motion.
Trolley & Hoisting Mechanism: Handles lifting and horizontal travel with fast and accurate positioning.
Crane Traveling Mechanism: Moves the crane along quay rails for extended loading/unloading coverage.
Electrical Control System: PLC-based system with frequency control, safety protection, and monitoring.
Operator Cabin: Ergonomic cabin offering wide visibility and comfortable, precise control.
Grab/Hook/Container Spreade: Interchangeable tools for bulk cargo, general cargo, or container handling.

 

Working Principle

The Portal Slewing Crane operates through coordinated control of its gantry walking mechanism, slewing platform, and hoisting system. The trolley travel mechanism provides longitudinal displacement; the slewing mechanism, comprising a slewing bearing and slewing drive, delivers torque to rotate the superstructure; the hoisting system, consisting of a winch, wire rope, and lifting gear, enables vertical lifting. Through vector combination of these three axes of motion, the crane can form arbitrary spatial lifting trajectories, meeting the continuous operation demands of high-frequency, heavy-load, and complex port conditions.

 

Customized Spreaders

The selection of lifting attachments for Portal Slewing Cranes offers versatility and can be changed according to different materials and requirements, meeting the diverse needs for bulk cargo, general cargo, containers, and other materials. When selecting attachments, comprehensive consideration must be given to the physical characteristics of the material (shape, dimensions, weight, material composition), packaging form, and handling efficiency. Below are the commonly used lifting attachments for Portal Slewing Cranes and their descriptions:

Hooks

Single-hook and double-hook types are available for handling piece goods, machinery, and bundled cargo during lifting operations.

C Hook

The shape is like the letter “C,” primarily used for hoisting coiled materials such as steel coils, paper rolls, and other rolled goods.

Container Spreader

Specifically designed for lifting standard containers, available in fixed, telescopic, and rotating models, it is a core lifting tool in modern ports.

Grab Bucket

Mainly used for loading and unloading bulk cargo such as coal, ore, grain, and sand. Double-lobed/multi-lobed types are available depending on the material.

Electromagnetic chuck

It uses electromagnetic force to attract magnetic materials and is suitable for processing magnetic materials such as steel plates, steel billets, scrap steel, and structural steel.
