Double Trolley General-Purpose Gantry Crane
Equipment Description
Application Fields
Serving a wide range of industries for large-scale material loading, unloading, handling, and assembly scenarios:
Port terminals, open-air warehouses, material yards: Completing container loading/unloading, bulk cargo handling, heavy equipment installation/disassembly, and stacking;
Railway/road engineering, wind power equipment manufacturing: Transporting and assembling long components like railway box girders and wind turbine tower sections, as well as large heavy structural parts;
New materials, heavy machinery manufacturing: Handling elongated materials like rolls in the new materials industry, as well as transporting large machine tools and steel structural components in workshop/field environments;
Shipbuilding support scenarios: Assisting in pre-processing and transportation operations for ship segments and components.
Product Advantages
Outstanding Operational Flexibility and Efficiency
The dual-trolley design enables both "independent small-load hoisting" and "coordinated large-tonnage/long-material hoisting," enhancing single-equipment efficiency while adapting to diverse material dimensions (e.g., wind turbine towers) and weight requirements through "collaborative hoisting," reducing reliance on a single lifting mechanism for heavy loads.
Stable Structure with Exceptional Durability
The main beam features a box-type welded structure with submerged arc automatic welding for main seams, incorporating non-destructive testing and stress-relief treatment (eliminating welding stress); supports employ box-type or gantry-style variable cross-section structures with superior load-bearing capacity; trolley drives often adopt "three-in-one" mechanisms, with hardened gear surfaces and disc brakes ensuring transmission reliability; outdoor equipment features anti-corrosion coatings like zinc-rich paint for complex conditions, extending service life.
Intelligent Precision for Smooth Operation
The electrical system integrates variable frequency speed regulation and PLC control technology, enabling stepless speed adjustment for precise lifting, movement, and positioning while minimizing start/stop impacts; equipped with intelligent skew correction and wireless anti-collision devices to further enhance operational accuracy and safety, meeting high-precision hoisting requirements in wind power, shipbuilding, and other industries.
Comprehensive Safety Assurance
Multiple safety features include load limiters, travel limiters, overload alarms, position protection, and wireless collision detection; brakes and wire rope safety factors meet high-grade standards (e.g., critical lifting mechanisms with brake safety factors ≥1.75, M6-grade wire ropes with safety factors ≥5.6), comprehensively mitigating operational risks.
Customized Adaptability with Broad Applications
Tailored solutions for industry-specific needs (wind power, ports, heavy industries) include customizable main beam spans, lifting capacities, and trolley configurations (e.g., lightweight or low-noise designs); adaptable to both indoor and outdoor conditions, ensuring stable operation from open material yards to workshop transition areas.
