Types of Portal Cranes

Portal cranes are available in four main types—Single-jib Portal Crane, Four-link Portal Crane, Fixed Portal Crane, and Floating Portal Crane, to meet different port and terminal handling requirements. Each type can be configured with different lifting tools, working ranges, and control systems according to the site conditions and cargo characteristics.

Four-link Type Portal Crane

Вот four-link portal slewing crane is a heavy-duty port lifting solution. Featuring a classic four-bar lifting mechanism, it delivers a stable lifting curve, optimized working radius, and seamless coordination between lifting, luffing, slewing, and traveling operations.

Featuring a rigid gantry structure, extensive working radius, and robust wind resistance, the four-bar linkage gantry crane is widely deployed in seaports, inland ports, terminals, shipyards, and bulk cargo yards. It supports efficient grab handling, hook lifting, and container spreader operations, making it an ideal choice for high-intensity port logistics.

We provide fully customized design solutions, including lifting capacity, working radius, lifting height, control systems, and duty class, to meet your specific site conditions and operational requirements.

Одностреловой портальный кран

The Single-jib Type Portal Crane is a versatile port lifting solution featuring a simplified boom structure and high operational flexibility. Its single-jib luffing mechanism enables smooth outreach adjustment, fast response, and efficient handling of general cargo, containers, steel products, and small bulk materials. With a compact upper structure and wide slewing radius, it is ideal for ports, terminals, shipyards, and logistics yards where space utilization and operational speed are key priorities.

The single-jib design has a stable performance, low maintenance requirements, and excellent adaptability to various lifting tools such as hooks, grabs, and container spreaders.
We offer customized configurations, including lifting capacity, outreach, rail span, lifting height, and control system options, tailored to your specific working conditions.

Fixed Portal Crane

Fixed portal cranes are large, high-efficiency boom-type cranes featuring immovable portal structures. Unlike rail-mounted portal slewing cranes, their bases are firmly anchored to foundations, ensuring long-term stable operation. Equipped with a massive boom system (including main boom and jib) and an operator cab, it enables extensive, high-intensity, continuous loading and unloading operations from a fixed position. It is particularly suited for scenarios requiring efficient material handling, such as ports, shipyards, industrial logistics, and power plants.

Our technical team can design a customized fixed portal crane solution for you. Contact us immediately to receive a tailored proposal and professional technical support.

Плавучий портальный кран

Плавучий портальный кран
The Floating Portal Crane employs a floating support structure, enabling stable operation on water surfaces or floating platforms. Unlike fixed gantry cranes, it requires no foundation anchoring and can move with ships or barges, facilitating flexible loading and unloading at ports, docks, and marine engineering sites. Equipped with a high-strength boom system (including main boom and jib) and operator cab, it delivers extensive, high-intensity, continuous material handling across varied positions. It excels in scenarios such as port bulk cargo handling, ship-to-ship cargo transfer, and offshore construction projects.

Суммирующий кран части поворотного

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.

Суммирующий кран части поворотного

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.

Принцип работы

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.

Индивидуальные разбрасыватели

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.

Ковш

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.

Lifting Beam

A rigid beam with multiple lifting points is used for lifting long objects (such as steel pipes or precast beams) to prevent deformation.

Спецификации

Weihua offers a full range of portal slewing cranes engineered for different port conditions, loading capacities, rotation requirements, and material-handling tasks. Each crane can be customized in terms of lifting capacity, outreach, rail gauge, slewing system, and attachment type to match your operational needs.
Below we present the specifications of two common configurations for your reference. For tailored solutions or special working conditions, our technical team is ready to design a customized model based on your project requirements.
