QDS intelligent unmanned crane

Technical Configuration

Technically, the QDS crane is a project-specific solution, with capacity, span, and lifting height defined entirely by the customer’s application requirements. The structure is available in both single-girder and double-girder configurations, utilizing European-style lightweight design principles that reduce wheel load and overall equipment height, thereby lowering building structural demands and maximizing usable headroom. The hoist mechanism is driven by a dedicated frequency-controlled motor, while the trolley and bridge travel drives are similarly equipped with stepless variable frequency drives. Electrical components are sourced from Schneider Electric as standard, with Siemens as a no-cost optional upgrade, ensuring global serviceability and compliance with international electrical codes. Control modes are tripartite: a cabin with full instrumentation for on-board operation, a wireless radio remote control for floor-level operation, and a pendant station for local maneuvering. The standard safety package includes overload limiters, dual mechanical and electrical final limit switches, anti-collision sensors for multi-crane installations, and emergency stop circuits. Optional features include laser or encoder-based absolute positioning systems for automated target docking, load sway control software, remote diagnostics via Ethernet, and integration with MES or ERP systems through OPC-UA or Modbus TCP protocols. The crane is designed and tested in accordance with GB/T 3811 and GB/T 14405 Chinese national standards, and can be engineered to meet FEM 9.511, DIN 15018, or CMAA 70 specifications upon request.

The QDS intelligent unmanned crane serves a broad range of heavy industries. In steel mills, it automates coil handling and slab yard transfers, reducing cycle times and eliminating operator exposure to high temperatures. In ports and intermodal terminals, it performs container stacking and retrieval with repeatable accuracy. In automotive manufacturing, it handles body-in-white and powertrain components through multi-station production lines. In chemical processing and coating facilities, as demonstrated by the Hunan large-scale coating project, the crane autonomously moves workpieces through dipping, curing, and drying stages without human intervention. In logistics and warehousing, it manages high-density storage of palletized goods in narrow-aisle configurations. In nuclear and power generation, it provides remote handling for fuel assemblies and maintenance components where radiation safety is paramount.

Choosing Chunhua Crane as your supplier delivers a direct factory price advantage of 30% to 50% below equivalent European-branded systems, without compromising on component quality or engineering rigor. All QDS cranes are supplied with CE certification for European markets and CCC certification for Chinese domestic projects, with documentation prepared in English, French, or Spanish as required. Our in-house engineering team provides custom structural and electrical design for each order, including finite element analysis of the main girders and load-bearing connections. We guarantee a formal quotation with preliminary CAD layout within four hours of receiving your inquiry, and our logistics department ships to over 60 countries via major sea freight carriers, with full container or break-bulk options available.

The ordering process is straightforward and transparent. Initiate your inquiry via WhatsApp or email with your required capacity, span, lifting height, and any special environmental conditions. Our engineering team will respond within four hours with a detailed quotation, technical datasheet, and a dimensional CAD drawing. Upon acceptance, a 30% T/T deposit is required to begin production. Manufacturing lead time is 30 to 45 days, depending on complexity and current factory load. The balance of 70% is due before shipment. We handle all export documentation, including bill of lading, packing list, and certificate of origin. Optional on-site installation supervision and commissioning can be arranged at a separate cost, performed by Chunhua field engineers or authorized local partners.
