Portal Boom Crane
Portal boom crane is mainly applicable to deck, ports, floating docks and outfitting sites for hull splicing, equipment outfitting and other lifting work, using the hook as a spreader.
- Lifting Height:10~35 meters
- Outreach:6-50 meters
Product Description:
The Portal Boom Crane is a heavy-duty lifting device featuring a portal frame base, offering robust stability and flexible rotating boom functionality. It is equipped with lifting, rotating, boom extension, and travel capabilities, specifically designed for applications requiring precise lifting over a wide range, with a maximum lifting capacity of 300 tons. It is primarily used in applications such as port container handling, shipyard section lifting, hydroelectric dam construction, and railway logistics transshipment. Its gantry structure allows vehicles to pass through, enabling efficient collaborative operations, making it a core material handling solution in the heavy industrial sector.
Portal crane parts:
Portal Crane mainly consists of a metal structure, hoisting mechanism, rotating mechanism, boom adjustment mechanism, traveling mechanism, boom system, operator cab, and electrical system. Below are the functional characteristics of each component:
Advantages:
-
Wide coverage:
Gantry structure + rotating boom design enables 360° rotation and wide-area coverage, suitable for open sites such as ports and shipyards.
-
High load capacity:
Maximum lifting capacity of over 300 tons, meeting the needs of large component lifting.
-
Precise positioning:
Equipped with variable frequency speed control and PLC control systems, lifting positioning accuracy reaches ±5mm, suitable for precision assembly scenarios.
-
High-efficiency accessibility:
Vehicles or tracks can pass beneath the gantry, enabling simultaneous “lifting + transportation” operations to enhance logistics efficiency.
-
Strong environmental adaptability:
Features wind-resistant anchoring devices and corrosion-resistant coatings, designed to withstand harsh port conditions such as high salt fog and dust.
-
Modular maintenance:
Key components (such as slewing bearings and steel wires) feature quick-release designs to minimize maintenance downtime.
