This Heavy Coil AGV acts as a specialized high-capacity transit station for the autonomous movement of steel, aluminum, and wire coils in demanding industrial environments. Built as a custom engineered-to-order (ETO) solution, the system features a reinforced chassis equipped with integrated V-shaped saddles to ensure absolute load stability. Capable of managing payloads from 20T to over 100T+, this Heavy Coil AGV eliminates the risks associated with overhead cranes, providing a precision-aligned interface between rolling mills and storage yards.

Gradin Heavy Coil AGV Structural Integrity and FEA Validation
Transporting heavy coils creates extreme point loading that can compromise standard AGV chassis. The Gradin Heavy Coil AGV is built upon a high-tensile steel frame that has been subjected to intensive Finite Element Analysis (FEA). This ensures that the structural integrity of the vehicle remains uncompromised under 60-ton loads, even during rapid acceleration or emergency braking. Our bespoke chassis design accounts for the specific center of gravity of your coils, distributing weight evenly across the heavy-duty wheel modules to prevent floor damage and ensure long-term mechanical reliability in 24/7 steel mill operations.
Gradin Heavy Coil AGV Advanced Load Security and V-Cradle Design
The safety of the coil during autonomous transit is our engineering priority. Every Gradin Heavy Coil AGV features an application-specific V-cradle or saddle system. Unlike generic platforms, our cradles are lined with high-friction, non-marking materials (such as polyurethane or specialized nylon) to prevent surface scratches and metal-to-metal slipping. For coils with varying diameters, we offer motorized adjustable cradles that automatically reconfigure their geometry to ensure a perfect, secure fit. This precision load seating is critical for preventing catastrophic rolling during high-speed turns or multi-directional maneuvers.
Gradin Heavy Coil AGV Intelligent Navigation and Systems Integration
Moving 40 or 60 tons of steel through a busy factory requires sophisticated intelligence. The Gradin Heavy Coil AGV utilizes LiDAR-based SLAM navigation, allowing it to operate autonomously without the need for floor-embedded magnets or tapes. The vehicle communicates directly with your WMS (Warehouse Management System) and MES (Manufacturing Execution System) via industrial Wi-Fi or 5G. This Industry 4.0 connectivity allows the AGV to optimize its own paths, autonomously manage battery charging cycles, and dock with production machinery with millimeter-level precision, creating a fully closed-loop automated logistics ecosystem.
Steel and Aluminum Mill Cold/Hot Rolling Lines
The Gradin Heavy Coil AGV is the premier choice for transporting massive steel coils between the rolling mill and the storage warehouse. By automating this transit, mills eliminate the safety risks associated with traditional overhead cranes and heavy forklifts. Our AGVs are engineered with heat-resistant components and specialized shielding, allowing them to operate in environments where ambient temperatures are high. The bespoke steering logic allows the AGV to maneuver through tight corridors that would be impossible for conventional material handling equipment to navigate.
Automotive Stamping and Press Shop Logistics
In automotive press shops, maintaining a constant supply of steel coils is essential for production uptime. The Gradin Heavy Coil AGV streamlines the Quick Die and Coil Change process by delivering coils directly to the uncoiler station. By utilizing synchronized docking sensors, the AGV aligns the coil perfectly with the mandrel, allowing for a seamless transfer. This level of automated precision reduces manual intervention, minimizes the risk of damage to expensive automotive-grade steel, and significantly improves the overall ergonomics of the press line environment.
Heavy-Duty Paper and Foil Processing Facilities
For the paper and packaging industry, handling massive paper rolls requires a delicate touch despite the high tonnage. We engineer the Gradin Heavy Coil AGV with soft-start/stop drive logic to ensure that sensitive paper or foil layers are not damaged by sudden inertia. The bespoke clamping and cradling systems are designed to maintain a consistent pressure that secures the roll without crushing the core. This specialized engineering makes the Gradin AGV an essential asset for facilities looking to automate their roll-handling logistics while maintaining the highest product quality standards.
Redundant Safety Architecture and Dynamic Obstacle Detection
When moving loads up to 60 tons autonomously, safety redundancy is non-negotiable. The Gradin Heavy Coil AGV is equipped with a multi-layered safety perimeter that includes dual-laser scanners providing 360-degree field-of-view protection. The system features intelligent field switching, which automatically adjusts the warning and stop zones based on the vehicle’s current speed and load status. Furthermore, we integrate on-board load cells that monitor the weight and stability of the coil in real-time. If the system detects any load shift or unexpected obstruction, it executes a controlled emergency halt, ensuring the safety of personnel, infrastructure, and the high-value cargo.
For this heavy-duty series, we can engineer load capacities up to [300] tons, with platform dimensions and lifting heights customized to your operational envelope. Requirements exceeding our standard engineering matrix will undergo a Finite Element Analysis (FEA) by our engineering team to ensure structural viability before proposing a solution.
To initiate the engineering proposal, please provide the following baseline data:
Rated Load Capacity
Maximum Lifting Height & Closed Height
Platform Dimensions (L x W)
Duty Cycle (e.g., operational cycles per hour/day)
Environmental Conditions (e.g., indoor/outdoor, washdown, explosion-proof)
Pit depth or overhead clearance constraints
Yes. The control systems can be equipped with standard communication protocols (e.g., Profinet, Modbus, Ethernet/IP) utilizing [Siemens / Allen-Bradley / Omron] PLCs. This ensures seamless I/O signal synchronization with upstream/downstream conveyors, AGV/AMR units, and your central control room.
Every custom unit undergoes a mandatory Factory Acceptance Test (FAT) prior to dispatch. This includes continuous operational testing at 100% rated load, static overload testing at [120% / 125%] capacity, and the physical triggering of all mechanical anti-fall and hydraulic safety interlocks. FAT documentation and video proof are included in your engineering package.
Upon final approval of the General Arrangement (GA) drawings, the manufacturing lead time is typically 4 to 8 weeks. Oversized structural components are engineered with a modular design to fit into standard shipping containers (20FT/40HQ). On-site assembly utilizes pre-engineered bolted flange connections and heavy-duty aviation plugs, strictly eliminating the need for field welding.
We provide a standard [12/24]-month warranty covering the structural frame and primary hydraulic/electrical components. To minimize operational downtime, a comprehensive set of standard consumables (e.g., cylinder seal kits, travel switches, relays) is shipped alongside your equipment. During the warranty period, replacement parts for non-human-induced failures are dispatched via priority air freight (DHL/FedEx) within 48 hours.
Beyond the warranty, we guarantee lifetime engineering support. Your custom equipment's CAD drawings, electrical schematics, and BOM (Bill of Materials) are permanently archived in our system. This ensures you receive uninterrupted remote troubleshooting, maintenance guidance, and exact spare parts matching for the entire lifecycle of the equipment.
