How does heavy duty AGV change the logistics efficiency of shipbuilding industry?

What is a heavy AGV for shipbuilding Industry?

For the shipbuilding industry, a heavy AGV refers to an intelligent device, which is designed to adapt to the shipbuilding scene, with a load capacity of 10 tons or more, and can automatically transporting heavy materials such as hull segments, large molds, steel profiles and outfitting parts. Different from ordinary AGV, heavy duty AGV used in shipbuilding must deal with the unique characteristics of this industry: large product volume, heavy weight of a single piece, diverse varieties, long production cycle and complex operating environment(Source: ISO 6385:2019).

Traditional shipyard material handling mainly relies on gantry crane, track flat cars and manual forklift, which has poor flexibility, low coordination efficiency, high safety risks and large space occupation. It is a key support for the shipbuilding industry to change from labor-intensive to flexible and digital production.

Core technical support system for heavy AGV

The stable operation of heavy duty AGV in shipbuilding field depends on the cooperation of various technologies, and the core technical system covering five modules.

1. Heavy-load bearing and driving system: High-strength steel frame is adopted, combined with multi-motor coordinated driving and large-diameter heavy-load steering wheel, with a single bearing capacity ranges from 10 tons to 50 tons, and multi-vehicle linkage can realize the transportation of 100 ton material. It has the functions of anti-eccentric load and shock absorption, ensuring the smooth transportation of irregular heavy materials.
2. Navigation and positioning System: Laser SLAM, visual navigation and magnetic stripe assisted navigation technologies are integrated, and the positioning accuracy reaches 10 mm, which resists the interference from metal parts in workshops, ground pipelines, ditches and other obstacles, and supports dynamic path planning and flexible steering in narrow spaces.
3. Intelligent scheduling control system: Based on 5 edge computing technology, the agv robot system realizes cluster scheduling and real-time task assignment of multiple AGVs. It can be seamlessly connect with MES (Manufacturing Execution System), WMS (Warehouse Management System) and vertical warehouse PLC, forming a closed-loop production line cooperation.
4. Safety Protection System: Equipped with 360 ° laser radar obstacle avoidance, mechanical anti-collision edges, sound and light alarms, and emergency braking modules. Outdoor models are provided with waterproof and dustproof design above IP 65 and high and low temperature resistance at -10℃ ~ 50℃.
5. Adaptive Leveling System: Through hydraulic lifting and horizontal self-test functions, materials are kept horizontal during transportation to avoid deformation or sliding due to uneven force.
