QD intelligent unmanned crane

Technical Configuration

The QD intelligent unmanned crane is configured to meet project-specific requirements, with capacity, span, and lifting height determined by the application. The standard structure is a European-style winch-driven double-girder bridge crane, offering excellent rigidity and reduced deadweight compared to traditional designs. The crane can be supplied with single-girder configurations for lighter loads where budget or clearance is a concern. The hoisting mechanism utilizes a high-performance winch with variable frequency drive control, ensuring smooth acceleration and deceleration during automated cycles. Electrical components are available with Schneider or Siemens options, providing reliable performance and ease of integration into existing plant networks. Control modes include cabin operation, radio remote pendant, and fully autonomous ground station control. The system comprises three major subsystems: a dispatching system for task assignment and traffic management, a ground driving monitoring system for real-time diagnostics and safety oversight, and a 3D scanning imaging system that enables precise load detection and positioning. Safety devices include overload limiters, anti-collision sensors, emergency stop circuits, and end-of-travel buffers. Optional features include optical communication systems for full vehicle-to-ground station linkage, circular unloading capabilities for continuous material flow, and custom end effectors for specialized loads such as aluminum coils or steel slabs.

This crane is purpose-built for industries requiring high-duty-cycle automation and precise load handling. Primary applications include aluminum processing plants, where the crane handles coils with exact positioning to avoid surface damage; steel mills for slab and billet transport; heavy equipment manufacturing facilities for assembly line feeding; port and intermodal yards for container or bulk material handling; large-scale warehouses with automated storage and retrieval systems; and foundries requiring reliable operation in high-temperature environments. The crane operates over 18 hours per day in continuous production settings, with a proven track record of more than two years in a major Henan aluminum project.

Chunhua Crane offers direct factory pricing that typically undercuts European brands by 30 to 50 percent, providing a cost-effective alternative without compromising on performance or safety. All cranes can be manufactured to CE or CCC standards, and we also comply with FEM, DIN, CMAA, and GB/T crane design codes as required. Our engineering team provides custom design services for non-standard spans, lifting heights, and control interfaces, with a four-hour quotation turnaround on most inquiries. With over two decades of experience since our founding in 2003, we have exported to more than 60 countries worldwide, and our sea freight logistics network ensures reliable delivery to major ports across Asia, Europe, Africa, the Americas, and the Middle East.

The ordering process is straightforward and designed for international buyers. Submit your project specifications via WhatsApp or email, and our engineering team will respond with a detailed quotation and preliminary CAD drawing within four hours. Upon acceptance, a 30 percent T/T deposit is required to initiate production. Manufacturing typically takes 30 to 45 days, depending on complexity and current workload. The balance is due before sea freight shipment, and we can arrange optional on-site installation and commissioning support through our network of local service partners.
