WHAT IS A PORTAL CRANE?
Heavy-Duty Lifting Solution for Industrial Facilities and Open Yards
Portal cranes are among the most powerful and versatile lifting systems used in modern industry. They are widely utilized in steel fabrication plants, precast concrete facilities, shipyards, energy projects, logistics centers, and heavy machinery manufacturing plants where large and heavy loads must be handled safely and efficiently.
Unlike traditional overhead cranes that rely on building structures, portal cranes operate on their own supporting legs and travel along ground-mounted rails. This unique design makes them ideal for both indoor and outdoor applications, especially in large production areas and open storage yards.
As industrial investments continue to grow across Türkiye and global markets, portal crane systems have become a critical component of efficient material handling operations.
What is a Portal Crane?
A Portal Crane, also known as a Gantry Crane, is a lifting system supported by legs that move on rails installed at ground level.
Unlike overhead bridge cranes that require runway beams attached to a building structure, portal cranes are completely self-supporting. Their independent design allows them to operate efficiently in open areas where building-mounted crane systems are not practical.
Portal cranes are commonly used for:
- Heavy load handling
- Steel structure transportation
- Large equipment lifting
- Outdoor material handling
- Industrial logistics operations
Their flexibility and high lifting capacity make them one of the most preferred crane solutions in heavy industries.
How Does a Portal Crane Work?
A portal crane system consists of four primary components:
Main Bridge Girder
The main structural element that supports the trolley and lifting equipment.
Portal Legs
Support the bridge structure and transfer loads to the ground rails.
Hoisting System
The lifting mechanism used to raise and lower loads safely.
Rail System
Allows the entire crane to travel along the working area.
Together, these components enable efficient transportation of heavy materials across large industrial facilities.
Types of Portal Cranes
Different industries require different portal crane configurations.
Single Girder Portal Crane
Single girder portal cranes provide an economical lifting solution for medium-duty applications.
Advantages include:
- Lower investment cost
- Lightweight construction
- Easy maintenance
- Reduced structural requirements
They are commonly used in manufacturing facilities and storage areas.
Double Girder Portal Crane
Double girder portal cranes are designed for heavy-duty industrial operations.
Advantages include:
- Higher lifting capacities
- Greater lifting heights
- Larger span capabilities
- Continuous heavy-duty performance
These systems are commonly used in steel plants, shipyards, and large industrial facilities.
Semi Portal Crane
A semi portal crane operates with one side supported by a building structure and the other side supported by ground rails.
This design offers excellent space utilization and flexibility.
Synchronized Double Portal Crane
Synchronized portal crane systems consist of two cranes operating simultaneously to handle oversized and extremely heavy loads.
They are frequently used in:
- Shipbuilding facilities
- Energy projects
- Heavy steel fabrication plants
- Infrastructure projects
Where Are Portal Cranes Used?
Steel Fabrication Plants
Used for transporting steel beams, columns, and structural components.
Precast Concrete Facilities
Ideal for handling concrete beams, columns, and prefabricated elements.
Shipyards
Used for lifting and positioning ship sections and large marine components.
Energy Industry
Supports the handling of turbines, transformers, and heavy power generation equipment.
Heavy Machinery Manufacturing
Facilitates the assembly and transportation of large industrial machines.
Outdoor Storage Areas
Provides efficient material handling across open yards and logistics centers.
Advantages of Portal Cranes
Suitable for Outdoor Applications
One of the biggest advantages of portal cranes is their ability to operate effectively in open environments.
High Lifting Capacity
Portal cranes can be designed with capacities such as:
- 10 Ton Portal Crane
- 20 Ton Portal Crane
- 32 Ton Portal Crane
- 50 Ton Portal Crane
- 100 Ton Portal Crane and above
Large Working Coverage
They provide extensive operational coverage over large production and storage areas.
Independent Structure
No building support structure is required.
Long Service Life
When engineered correctly, portal cranes offer decades of reliable operation.
Factors to Consider When Choosing a Portal Crane
Lifting Capacity
The maximum load must be accurately determined.
Span Length
The crane span should match the dimensions of the working area.
Lifting Height
Must be designed according to operational requirements.
Duty Classification
The appropriate FEM duty class should be selected.
Safety Systems
Modern portal cranes should include:
- Overload protection
- Dual braking systems
- Emergency stop functions
- Limit switches
These features ensure safe and reliable operation.
Factors Affecting Portal Crane Prices
Portal crane prices vary depending on:
- Lifting capacity
- Span length
- Lifting height
- Single or double girder design
- FEM duty classification
- Automation level
- Installation requirements
Because every industrial project has unique requirements, portal cranes are typically engineered and priced individually.
