Gantry crane
Lifting mechanism: Mostly driven by winches or electric chain hoists, using wire ropes/chains to move hooks (or grabs, spreader beams, and other attachments) for lifting and lowering loads;
Equipment Description
Lifting mechanism: Mostly driven by winches or electric chain hoists, using wire ropes/chains to move hooks (or grabs, spreader beams, and other attachments) for lifting and lowering loads;
Luffing mechanism: Adjusts the inclination angle of the lifting jib to change the working radius and cover different areas;
Slewing mechanism: Drives the jib to rotate around a vertical axis, enabling full-range operation coverage;
Traveling mechanism: Moves the gantry horizontally along rails, expanding the operational site range.
Modern models often feature box-type or truss-style jibs, paired with advanced electrical control systems such as PLC control, variable frequency speed regulation, and wireless remote control. They can also be flexibly equipped with grabs, spreader beams, hooks, and other attachments based on specific scenarios.
Application Fields
Ports and terminals: Loading and unloading of ship cargo (bulk, breakbulk, and containers), as well as stacking and transporting yard goods;
Shipbuilding industry: Hull block assembly and equipment installation on shipways and floating docks (maximum lifting capacity up to 300 tons, some models equipped with micro-motion devices for precision installation);
Construction and installation projects: Large dam irrigation in hydropower stations, lifting of prefabricated components (e.g., bridge girders, power station equipment) (featuring integrated transport convenience and deep lowering capabilities);
Mining and bulk material yards: Efficient handling and transportation of bulk materials like ores and coal, as well as breakbulk such as steel coils and heavy machinery components.
Product Advantages
With its "slewing + luffing + lifting + traveling" compound motion capability, it achieves 360° full rotation, covering an operational radius of 10-50 meters. It can simultaneously service ships, vehicles, and yards, reducing equipment relocation time. The lifting capacity ranges from "several tons to hundreds of tons," with adjustable lifting and luffing speeds (low-speed stability for heavy loads to prevent impact, high-speed efficiency for light loads), suitable for mixed operational scenarios. A single unit can complete hundreds of lifting cycles daily, supporting large-scale material throughput.
Advanced technology, energy-efficient and reliable
Power and control: Equipped with permanent magnet motors + variable frequency control systems, motor efficiency reaches 93%-97%, saving over 40% energy, and reducing fault maintenance time by 50%. Some models feature energy feedback and smart low-voltage capacitor compensation, with an average power factor exceeding 0.9, lowering both energy consumption and grid pollution.
Anti-sway and precision: Includes dual four-bar anti-sway and torque anti-sway systems (e.g., patented four-rope anti-sway technology), combined with electronic anti-sway measures, significantly reducing attachment swing (e.g., spreader beam swing controlled within ±250mm), improving lifting alignment accuracy. Also supports "automatic container tracking and soft landing" smart functions.
Comprehensive safety protection, strong adaptability
Equipped with storm warnings, dynamic safety scanning, wind-resistant anchoring systems (including horizontal force anchors, anti-tilt ropes, and anti-creepers), and gantry intelligent skew correction (real-time track deviation correction to prevent derailment), ensuring full-range stability. The main structure uses rigid gantry + heavy-duty steel construction, capable of 24-hour high-intensity operation in outdoor environments. Core components (motors, reducers, etc.) feature reinforced designs for easy troubleshooting and maintenance, minimizing downtime.
Customization and multi-functional expansion
Offers full-series customized products (e.g., universal port gantry cranes, shipyard-specific gantry cranes, construction gantry cranes) with flexible attachment switching (quick-change grabs, spreader beams, hooks). Capable of handling bulk, breakbulk, and container loading/unloading, while also supporting "dual-crane coordination, precision heavy lifting" and other special process requirements.
