Product DescriptionSingle-Jib Portal CraneSingle-jib portal cranes are known for efficient cargo handling at ports based on slewing, luffing, traveling, and hoisting functions. They are designed for demanding scenarios including ports, terminals, shipyards, and steel mills. Featuring a compact structure with 360° full slewing capability, single-jib portal cranes deliver extensive operational coverage and heavy-duty continuous operation resilience. Compared to four-link portal cranes, they feature lighter deadweight, lower energy consumption, and reduced maintenance costs. Widely used in bulk cargo, general cargo, and container handling operations, they stand as one of the mainstay models of modern green and energy-efficient port handling equipment.SpecificationApplications1. Port Terminals: Used for loading/unloading ships and vehicle cargo, including general cargo, bulk cargo, and containers.2. Rail Freight Yards: Train loading/unloading, including general cargo, bulk cargo, and containers.Key Configurations1. Unique Design of Slewing Bearing that Enables Crane-Synchronized LifespanOur decades-accumulated machining expertise and membership on China's Boom Crane Standardization Committee ensure the slewing bearing – the most critical mechanical component of portal cranes – achieves identical operational lifespan as the entire machine.2. Low-Center-of-Gravity DesignSpecial Steel Wire Rope Reeving with Low-wear DesignUtilizing same-direction parallel winding, this method significantly reduces wire rope wear, extends service life by over 20%, and lowers maintenance and replacement costs.3. Low-Center-of-Gravity DesignThe high-boom, low-slewing-platform design concept lowers the center of gravity of portal cranes, significantly enhancing overall machine stability.4. Quick-Change Spreader SystemThe quick-change interface enables seamless switching among grabs, hooks, and container spreaders within 3-5 minutes.5. Spreader Auto-TrackingContainer spreaders synchronize counter-rotation with the slewing mechanism, maintaining parallel alignment with trucks at all times in a way to boost loading efficiency6. Full Electric DriveEco-friendly operation with 380V–20kV power compatibility7. Steel Rail Travel SystemForged steel wheels support higher loads with minimal wear, eliminating frequent wheel replacements and slashing maintenance costs8. Multi-Level Safety ProtectionsIntrinsic crane safety remains our core objective. The redundant design of multiple safety mechanisms,combines real-time data tracking via cloud-based monitoring systems to ensure operational safety.9. Anti-Sway Grab Control SystemModeling of the portal slewing system enables calculation of grab swing angles. Intelligent control regulates slewing and luffing speeds to eliminate swing, achieving effective sway elimination.10. Automated Operation SystemPortal cranes memorize material loading/unloading positions and operation paths. Combined with grab anti-sway, precision positioning, and collision avoidance algorithms, this enables fully automatic grab operations.11. Boom Anti-Collision SystemBoom anti-collision system utilizes real-time monitoring of portal crane radius, boom angle, and positional coordinates to establish a collaborative equipment network. By sharing operational data with adjacent machinery and constructing a group intelligence model, the system implements intelligent algorithms to provide active boom collision protection.Technical Specifications(Custom configurations available upon request.)Main Technical Parameters of Portal Slewing CranesBasic ParametersRated Lifting Capacity (t)Hook10,16,20,25,30,35,40,50,63,80,100,125,150,200,250,300,400,500,600,650Container Spreader35/41Grab Bucket10,16,20,25,30,35,40,45,50Lifting Height (m)Above Rail10~75Below Rail5-30Maximum Working Radius (m)20-75Minimum Working Radius (m)8~20Speed ParametersHoisting Speed (m/min)20-70Luffing Speed (m/min)20-60Slewing Speed (r/mn)0.8/1/1.2/1.5Gantry Travel Speed (m/min)25/30
