Gantry crane

Product Overview
The Weiyuan Heavy Duty MG Type Gantry Crane is built to streamline bulk material handling and vehicle loading in high-throughput outdoor yards. Operating on ground-level crane rails, this double-girder gantry crane features single or double cantilever boom extensions that let the hook reach beyond the track footprint. This allows operators to load flatbed trailers, rail cars, and storage bays without repositioning transport vehicles inside the runway track. Compatible with standard lifting hooks, electro-magnets, grab buckets, and rotating C-hooks, the Weiyuan MG Crane provides a flexible, high-density material handling system for steel distribution hubs, precast concrete yards, and regional freight transfer stations.

Product Advantages
Engineered for Outside Lifting: Fully sealed IP55 junction boxes, silicone-sealed drive motors, and shielded electrical festoon systems ensure smooth operation under rain, dust, and direct sunlight.
Heavy-Duty Lifting Power: Box-girder bridge construction paired with an industrial winch trolley handles continuous duty cycles, moving heavy steel bundles, pipe racks, and stone slabs with ease.
Superior Stability and Reach: Single or double cantilevers extend up to 10m–12m past the rail center, maximizing yard storage capacity and speeding up flatbed truck turnaround times.
Durable and Low-Maintenance: High-grade carbon steel structural members, flanged steel wheels, and grease-packed bearing blocks minimize daily service requirements.
Customized to Your Needs: We configure rail gauge, cantilever lengths, hoisting speeds, and specialized below-the-hook lifting attachments based directly on your yard dimensions and cargo mix.

Application Scenarios
Outdoor Stockyards: Speeds up the loading, sorting, and stacking of structural steel plates, round pipes, and wire rods using magnetic or mechanical spreaders.
Precast Concrete Facilities: Moves cured concrete slabs, bridge box girders, and utility pipes from casting lines directly onto transport trucks.
Heavy Industrial Plants: Connects outdoor storage zones with indoor fabrication bays for smooth, continuous flow of large raw materials.
Stone and Quarry Industry: Stacks rough-cut marble and granite blocks in outdoor holding yards and loads them onto shipping containers.
Construction Sites: Serves as the central yard crane for staging heavy structural components, formwork, and reinforcement cages on major infrastructure jobs.
