Recently, Guangzhou fired the first shot in digital new infrastructure, with AGV at the dock receiving much attention. The Guangzhou Port Company stated that it will utilize the globally created "unmanned driving technology applied to intelligent container trucks" to build a fully automated terminal in the Greater Bay Area.
This also indicates that under the new infrastructure, heavy-duty AGVs have ushered in a wave of development boom. Heavy duty AGVs are characterized by their large size and high load-bearing capacity, and can automate the processing, manufacturing, and handling of large objects. In some heavy machinery factories, railway transportation, special industries, ports and airports, large voltage transformer factories, heavy vehicle manufacturing plants, and other places, large tonnage AGVs are needed to meet the requirements.
In the past two years, with the expansion of the application field of heavy-duty AGV, some enterprises have also developed related products. However, compared to light-duty AGVs, heavy-duty AGVs face higher technical conditions (working accuracy, control systems) and supporting facilities, with significantly different design structures and component selection standards. Therefore, when enterprises enter the field of heavy-duty AGVs, the R&D and production thresholds are relatively high.
However, there are still some heavy-duty AGV manufacturers in China that have achieved good results.

Hunan Chizhong
Chizhong AGV products have been successfully applied in major automobile manufacturers such as Shanghai Volkswagen, Shanghai Automotive, SAIC General Motors, SAIC GM Wuling, GAC Fiat, Yanfeng Biou, and other large automobile, electronic, and component manufacturers.
The Chizhong Robot 200T heavy-duty AGV has a size of 6 * 8m and a load weight of 200T. It has 4 drive units to achieve forward, backward, and lateral movement (omnidirectional walking), with a climbing ability of not less than 5%. The ground roughness is 20mm, the groove width is 30mm, the driving accuracy is ± 30mm, the lifting platform accuracy is ± 5mm, the waterproof level is IP57, and the safety and explosion-proof level is IIC. It can achieve both manual and automatic operation modes.
The smooth development, production, and use of the 200T heavy-duty AGV can comprehensively improve the long-term backwardness of China's heavy-duty industrial mobile robots compared to European and American countries, and greatly promote the widespread application of this equipment in fields such as wind turbines, port logistics, shipbuilding, and aircraft manufacturing.

Aijiwei
At present, Aijiwei's heavy-duty AGV can withstand a weight of about five tons with high energy. They have application cases from Dongfeng Motor and mature scientific research technology.
Suzhou Aijiwei Robot Co., Ltd. was established in December 2011. The company's independently developed AGV product line for handling robots includes the non reflective laser AGV series with US and national invention patents, as well as integrated solutions for intelligent factory information logistics software such as WMS, WCS, RFID, etc.
In the past two years, many factories have undergone intelligent upgrades and transformations, and the demand for laser forklifts and AGVs has increased. The market growth is relatively fast - Aijiwei AGV focuses on the construction and transformation of intelligent logistics systems, and its products have been widely used in industries such as tires, automobiles, clothing and textiles, 3C electronics, home appliances, and machinery manufacturing. The market is spread throughout the country and exported to Europe and America.

Kaiyun Lai
Kaiyunlai heavy-duty load-bearing AGV adopts Japanese precision DC brushless motor, which changes the previous disadvantage of poor positioning accuracy of heavy-duty AGVs. At the same time, it adopts comprehensive safety measures such as Beiyang laser obstacle avoidance sensor and safe edge contact, greatly improving the safety performance of the product.
The characteristic of Kaiyunlai 5-ton heavy-duty AGV is that the driving wheels can ensure a certain degree of pressure even when encountering uneven road surfaces, reducing slipping and expanding the use of navigation vehicles. In addition, due to the use of imported branded products as the core components, Kaiyunlai heavy-duty load-bearing AGV has excellent reliability.

Zhenhua Heavy Industry
Zhenhua Heavy Industry started with port machinery and has an environmentally friendly, safe, and efficient fully automated container terminal loading and unloading system. It uses double 40 foot container shore bridges, fully automated distribution systems, and automated track cranes, greatly improving the efficiency of terminal loading and unloading.
Port terminals are currently a major focus area for outdoor AGV applications, and compared to ordinary AGVs, the heavy-duty AGV technology used in port terminals has more stringent requirements.
Taking the Yangshan Port Phase IV terminal completed by Zhenhua Heavy Industry as an example, from the moment the container leaves the cargo ship, 10 bridge cranes, 40 track cranes, and 50 AGV automatic navigation trucks start synchronously. Guided by 61483 ground magnetic nails, the AGV carries containers towards the target container area. The terminal loading and unloading operation adopts a production plan of "remote control of double trolley container bridge crane+track crane+AGV", mainly composed of automated loading and unloading equipment for terminal loading and unloading, horizontal transportation, and yard loading and unloading, as well as an automated terminal production control system.

Aggregation automation
As an emerging force in the field of logistics robots, Shanghai has previously focused more on aerospace and military industries, aviation manufacturing, rail transit, and other areas. In addition, the Mecanum wheel of Jiji is also its flagship product, but in recent years, Jiji has shifted its focus to the logistics AGV field.

So the heavy load AGV with centralized automation has the ability to move freely in a two-dimensional plane, including straight, horizontal, diagonal, arbitrary curve movement, 360 ° stationary and other omnidirectional movement forms. It can be manually controlled by remote control with a precision of ± 0.1mm and automatically repositioned with a precision of ± 0.5mm. Its 15 ton heavy load AGV has been applied in the State Grid, achieving fast docking, safety and efficiency.

Shandong Lingong
The Lingong "Blue Elf" DL30 intelligent AGV is a star product of intelligent handling launched by Lingong Group. The DL30 two-way backpack AGV has a load capacity of 3000KG and can be carried for transportation inside and outside the workshop. It has strong climbing ability for outdoor transportation and is suitable for cross workshop and long-distance outdoor operations. The heavy-duty transportation capacity of the Lingong "Smurfs" DL30 is a solution for many workshop handling enterprises, with strong allocation and transportation capabilities in warehousing and logistics.
Shandong Lingong is one of the core enterprises of Lingong Group and a large backbone enterprise in the national construction machinery industry. Shandong Lingong has replaced forklifts with various types of AGVs such as submerged, towed, and outdoor heavy-duty AGVs in the cutting, welding, and assembly workshops to meet the different needs of production logistics and improve efficiency for end customers.

Yunnan Kunchuan
Kunchuan AGV can meet the load capacity requirements from 50 kilograms suitable for the electronic and electrical, e-commerce logistics industries, to 300 ton heavy-duty AGVs suitable for aircraft, locomotives, and port terminals.
Kunchuan's "Intelligent Parking AGV" adopts self-developed composite navigation technology, driven by four independent bogies, and can achieve multiple operating modes such as spin, translation, and multi-directional SD. It can carry up to 3.5 tons and currently operates at a speed of 1.5m/s with a positioning accuracy of 5mm. The upper control system adopts the ATIS 4.0 (PRO) independently developed by Kunchuan Intelligent Company.
Kunchuan Intelligent Chairman Jiang Rongqi said, "In the future, Kunchuan's parking robot products will be extended to other industries. They can not only park small cars, but also large trucks, buses, etc. In addition to car parking, in the automotive manufacturing industry, they can also solve the handling of some testing, film pasting and other links after the car production is offline
