Weiyuan Heavy Duty QD Hook Overhead Crane for High-Capacity Industrial Workshop Lifting
Product Overview
The Weiyuan Heavy Duty QD Hook Overhead Crane is a heavy-duty, double-girder bridge lifting system engineered for high-capacity material handling inside industrial workshops. Operating on elevated runway beams, this crane features submerged-arc welded Q355B steel box girders that maintain minimal structural deflection under full rated capacity. The lifting system utilizes an open-winch crab trolley or heavy-duty wire rope hoist powered by hardened helical gear reducers and variable frequency drives (VFD) for smooth, millimeter-level load positioning. As Weiyuan’s premier industrial bridge crane, it provides continuous lifting power, high torsional resistance, and dependable performance for heavy machinery plants, steel service centers, and structural fabrication bays.
Product Advantages
Engineered for Workshop Productivity: Travels along elevated building runways, freeing up 100% of factory floor space for machines, aisles, and worker movement.
Heavy-Duty Lifting Power: The double-box girder design delivers high structural strength and uniform load distribution, supporting continuous lifting from 5t up to 500t+.
Superior Stability and Reach: Compact end carriage dimensions and short hook approach distances maximize hook coverage across the entire width and length of the workshop bay.
Durable and Low-Maintenance: Hardened gear reducers in sealed oil baths, forged 42CrMo steel wheels, and full VFD acceleration control reduce mechanical shock and rail wear.
Customized to Your Needs: Weiyuan customizes bridge span, lifting height, wheel load ratings, hoisting speeds, and below-the-hook spreaders to match your factory building layout.
Application Scenarios
Heavy Machinery Assembly Plants: Safely lifts, maneuvers, and aligns heavy machine tool beds, casting frames, and engines with high precision.
Steel Mills & Service Centers: Handles heavy steel plates, coils, billets, and profile steel packs across high-throughput processing bays.
Power Generation Facilities: Provides steady, controlled lifting for servicing heavy steam turbines, generators, and transformers during overhaul outages.
Paper & Processing Plants: Moves heavy calender rolls, dryer cylinders, and machinery components during regular manufacturing and maintenance.
Foundry & Smelting Workshops: Transports heavy casting molds, flasks, and intermediate foundry components under demanding thermal conditions.
