Portal boom crane is a heavy-duty lifting solution featuring a portal frame base and a rotating boom structure, designed for large-scale material handling operations in ports, shipyards, power plants, and infrastructure projects.
The crane combines lifting, slewing, boom adjustment, and traveling functions into one integrated system, providing excellent flexibility and wide-area operation capability. Its portal structure offers high stability while allowing vehicles, rail transport systems, or other equipment to pass underneath, enabling efficient coordination between lifting and transportation operations.
With a maximum lifting capacity of over 300 tons, the portal boom crane is designed for demanding applications such as container handling, ship section lifting, hydropower construction, and railway cargo transshipment. The rotating boom design enables precise load positioning across a large working radius, making it an essential heavy-duty lifting solution for modern industrial facilities.
Equipped with advanced variable frequency drive technology and PLC control systems, the portal crane provides smooth operation, accurate positioning, and reliable performance even under high-intensity working conditions.
Port and Container Terminals
Used for container handling, bulk cargo transfer, ship loading and unloading, and large equipment lifting operations to improve port handling efficiency.
Shipbuilding and Shipyards
Applied for lifting ship sections, hull blocks, marine equipment, and large structural components during ship construction and repair.
Hydropower and Infrastructure Projects
Suitable for lifting large mechanical components, turbines, generators, and construction equipment during dam and power station construction.
Railway Logistics Terminals
Used for cargo transshipment, heavy equipment handling, and railway-related logistics operations.
Heavy Manufacturing Industry
Provides lifting solutions for oversized machinery, steel structures, and industrial equipment installation.
Wide Working Coverage
The combination of a portal frame structure and rotating boom provides 360° slewing capability and extensive operating coverage, making it suitable for large open areas such as ports, terminals, and shipyards.
Heavy Lifting Capacity
Designed for large-scale lifting operations, the crane can achieve lifting capacities exceeding 300 tons, meeting the requirements of oversized equipment and heavy components.
High Precision Positioning
Equipped with frequency conversion control and PLC-based operation systems, the portal boom crane provides accurate lifting and positioning performance, with positioning accuracy reaching ±5 mm for precision assembly applications.
Efficient Transportation Integration
The open portal structure allows vehicles, rail systems, or transport equipment to pass underneath, supporting simultaneous lifting and transportation operations and improving overall logistics efficiency.
Excellent Environmental Adaptability
Designed for harsh industrial environments, the crane features corrosion-resistant coatings, wind-resistant anchoring systems, and durable components suitable for marine conditions, salt spray, dust, and outdoor operation.
Modular Maintenance Design
Key components such as slewing bearings, electrical systems, and wire rope assemblies adopt optimized designs for easier inspection, maintenance, and reduced downtime.
