Key Takeaways for Busy Procurement Managers:
Choose for cost-effectiveness: Air Cushion Vehicle
Choose for high performance: Heavy Duty AGV
Expert Advice: For transportation scenarios of extra-large transformers (over 1000 tons), long-term continuous operation, and precise docking installation, we recommend heavy duty AGV.
What is Heavy Duty AGV?
Heavy Duty AGV is an automatic guided vehicle, which is specially designed for carrying and transporting overweight loads, usually from 50 tons to over 2000 tons. As an advanced agv robot, it realizes automatic navigation, positioning, and movement through multiple navigation technologies such as laser, magnetic stripe, and vision, without the need for manual driving. It is mainly used to solve the B 2B pain points in the transportation of large-scale precision equipment such as transformers, including high requirements for stability and safety, high labor costs for manual operation, and low efficiency of traditional transportation methods.
Industry standard/generic name: In the field of transformer transportation, it is also commonly called “heavy automatic guided vehicle for transformers”. For related industry standards, please refer to GB/t 26944.1-2011 Automatic Guided Vehicle Part 1: General Technical Conditions and GB/t 26944.2-2011 Automatic Guided Vehicle Part 2: Safety Requirements.
Synonyms: Heavy-duty automated guided trolley, extra-heavy load AGV, transformer transportation AGV.

In-depth Analysis: Why Choose Heavy Duty AGV?
Pain point solution and core advantages after use: heavy duty AGV effectively solves the core B2B pain points in transformer transportation, and its value has been verified by industry data. The in-depth analysis and investment prospect research report of China autonomous vehicle industry (2025-2032) from Yan Guan Report Network (URL: https://m.chinabaogao.com/baogao/202501/740757.html ) shows that the application rate of heavy duty agv in heavy-duty transportation of transformers has surged by 67% in five years, making it the first choice for large manufacturers-mainly because it solves the pain point of high labor costs through full automation. By eliminating the need for professional drivers and auxiliary personnel, enterprises can cut annual transportation-related labor costs by approximately 52%, as noted in the same report. Aiming at the pain point of low transportation accuracy, its 5 mm high-precision positioning technology ensures accurate docking with transformer installation benchmarks, and reduces the rework rate caused by positioning errors from 12% to only 1.5%. Its 24-hour continuous operation ability further ensures the smooth progress of transformer production and installation.
Other key advantages of heavy agv include: 1. Efficiency enhancement: Shortens the average transportation cycle by 38%, accelerating transformer delivery and installation timelines. 2. Safety improvement: reduce the accident rate to below 0.5%, and protect high-value transformers and field personnel. 3. Intelligent management: the supporting control system can monitor and record the transportation process in real time, laying a foundation for the operations of intelligent factory.
How to Choose a Heavy Duty AGV
Step 1: Clarify Requirements
First, determine the key parameters of the transformer to be transported, including weight, volume, and type (oil-immersed or dry-type). Make clear the transportation scenario (workshop transportation, factory short-distance transportation or installation site positioning) and whether it needs continuous operation. For example, to transport 1,000 tons of oil-immersed transformers, which requires 24-hour continuous operation in the workshop, it is necessary to choose heavy duty agv with high load and high stability.
Step 2: Confirm Parameters
Based on the clarified requirements, confirm the key parameters of the heavy duty agv, including rated load capacity (it is recommended to select a model with a load capacity 10-20% higher than the transformer weight), bearing surface size (matching the transformer base), positioning accuracy (static positioning accuracy ≥ ± 5 mm for installation site scenarios), driving speed, and battery life (meeting the daily operation time requirements).
Step 3: Match Standards
Ensure that the selected heavy duty agv complies with relevant national standards (GB/t 26944.1-2011, GB/t 26944.2-2011) and industry norms. For the transportation scenario of oil-immersed transformer, confirm that the equipment has explosion-proof design, and the explosion-proof level is not lower than Ex d IIB T4. At the same time, check whether the equipment’s environmental adaptability meets the on-site conditions (such as working temperature, ground requirements).
Step 4: Verify Suppliers
Select suppliers who are experienced in R&D and production of heavy agv for transformer transportation. Check the qualification certificates, successful cases and after-sales service system of suppliers. It is suggested that the supplier’s workshop be inspected on site to test the equipment performance. Confirm the supplier’s after-sales service content, including installation and debugging, operator training and maintenance support (such as whether there is a 24-hour emergency maintenance hotline).

After the warranty period, we provide lifelong maintenance services, including replacement of wearing parts, software upgrade and equipment overhauls. At the same time, we set up a 24-hour after-sales service hotline to respond to customer ‘maintenance needs in time.
Summary
In the transport of transformers, heavy agv and air cushion vehicles have their own advantages and disadvantages. Air cushion vehicles is suitable for short-distance temporary transportation scenes with medium weight and general ground conditions, and have the advantage of less initial investment. Heavy Duty AGV, as a high-performance automated guided vehicle, has obvious advantages in load capacity, automation, precision, and safety. It is more suitable for the scene of super-large transformers, long-term continuous operation and precise docking installation. Although the initial investment is high, in the long run, it can bring about significant cost savings and efficiency improvements.
