single jib portal crane
Portal crane devides into two types : One is single-jib portal crane, and the other is four-link portal crane.Portal slewing crane
This crane type excels in environments requiring repetitive, heavy lifts over a fixed path, combining mobility with high load-bearing capacity. Its design prioritizes efficiency in structured settings like ports and rail hubs.
Haitai mobile harbour manufacturers &portal crane manufacturer , chinese portal slewing crane theoretical efficiency of them can be designed according to the customers’ demands. The portal slewing crane specifications combine maximum reliability and safety with high-operating efficiency, long-life, and low maintenance costs-leading to the lowest total cost of ownership.
A single jib portal crane is a type of overhead lifting equipment mounted on a portal frame, characterized by a horizontal arm (jib) used for moving heavy loads. Single jib portal crane is a kind of hoisting machine especially used inport,harbour, dock, shipyard with small investment for loading and unloading front apron container, sundries and bulk cargo.It mainly includes the following units: crane strong steel frame, lifting mechanism,luffing mechanism, slewing mechanism, traveling mechanism.The crane moves along rails, allowing it to traverse a predefined path while lifting, lowering, and transporting loads horizontally.
APPLICATIONS
Ports/Shipyards
The single jib slewing portal crane has become one of the core equipment in ports and shipyards due to its stable structure, large operating range and multi-functional adaptability.
The single jib portal crane has a fast lifting speed (up to 60m/min) and can efficiently complete container loading and unloading. It can load and unload bulk cargo such as coal, ore, and grain when equipped with a grab bucket, and the grab bucket capacity is usually 10-30 tons. It is used in shipyards for ship segment lifting, equipment installation and maintenance, emergency repair and maintenance, etc.
Rail Terminals
Handling freight or intermodal containers.Single portal cranes can replace traditional gantry cranes to lift train locomotives, track laying equipment, etc., covering a wider range of operations. The 360-degree rotation and luffing capabilities of portal cranes are useful in the narrow space of railway terminals and can cover multiple loading and unloading points. In addition, the portal structure has a low center of gravity design and is equipped with windproof anchoring devices to adapt to the open-air environment of railway terminals.
Industrial Facilities
Assembling heavy machinery or moving materials.Steel mills need to move heavy steel coils or furnace equipment, power plants need to lift large generator parts, and chemical plants need to handle large containers or reactors. The structural features of single-arm gantry cranes, such as gantry support, single-arm design, high load capacity and flexibility, can adapt well to these scenarios.
Construction Sites
The single jib slewing portal crane has become one of the core equipment in ports and shipyards due to its stable structure, large operating range and multi-functional adaptability.
Single jib portal cranes are used in the construction of large bridges. Pier segment lifting: Single-arm gantry cranes move along the bridge deck track to assemble prefabricated beams (weight 80-200 tons) segment by segment. Steel box girder installation: In cross-river/cross-canyon bridges, long-distance lifting is covered by large arm width. Super high-rise building construction, special terrain projects such as mountain buildings: gantry tracks are laid along the mountain platform to lift materials to different elevations. Waterside projects: such as dock or cross-sea bridge construction, crane tracks are extended to the pier to support ship-land material transfer.
