In early 2025, a manufacturing plant in the US Midwest reached out to YG Machinery. They needed a better way to move heavy metal castings across their factory floor. Their current method used large forklifts. The forklifts required skilled drivers. They also blocked aisles and created safety hazards. The plant manager sent a short inquiry. He wanted an Electric Transfer Cart that could handle a 30-ton load. That was the start of this project.

Project Background: Why a US Manufacturer Needed a 30T Electric Transfer Cart
The customer operates a heavy equipment assembly plant in Ohio. They produce large engine blocks and industrial machinery parts. The facility spans 15,000 square meters. The distance between the machining area and the assembly line is 150 meters.
Workers moved parts using two 15-ton forklifts. This process took two hours per trip. The forklifts also created traffic jams in the main aisle. The plant manager wanted to eliminate this bottleneck. He needed a machine that ran automatically. It had to fit within a 3.5-meter aisle width. Most importantly, it had to carry a 30-ton casting safely. He found our website and sent an email. He asked for a quote and a technical proposal.
Selection Process: Matching a Heavy-duty AGV to the 3.5-Meter Aisle
Our sales engineer reviewed the plant layout. The aisle width was 3.5 meters. The floor was concrete and flat. The load weight was 30 tons. We recommended the AGV-30T model. It is a true Heavy-duty AGV built for this exact workload.
The rated load is 30 tons. The table size is 4500×2200×600 mm. This fits the customer’s casting dimensions perfectly. The wheelbase is 3200 mm. The ground clearance is 50 mm. The machine uses four wheels with a 400 mm diameter. These wheels distribute the weight evenly. The maximum wheel load is 110.4 kN. The plant floor easily handles this pressure.
The customer asked about speed and control. We explained that the running speed is 0 to 20 m/min. This is safe for indoor factory environments. The machine can turn and park precisely. We also explained the motor power. It uses a 3.5 kW motor. The battery is 48V with a 250Ah capacity. This provides a full-load run time of 3.5 hours. The customer was satisfied with the technical match. They requested a formal quotation.
Customization: Configuring the AGV Transfer Platform for sale
The customer needed two specific modifications. First, they wanted a custom top plate. They needed recessed pockets to secure the castings during transport. Second, they wanted a remote control system. The operators needed to guide the machine manually in tight spots.
We confirmed both requests. Our engineering team designed the top plate within three days. The remote control added a wireless module to the control box. We sent the updated proposal. It was for one AGV Transfer Platform for sale, including shipping to New York. The customer signed the contract and paid the 30% deposit. Production started immediately.

Factory Testing: Validating the Factory Automation AGV Under Load
Production took 25 days. Our team built the frame using heavy-duty steel to meet US industrial safety standards. We installed the 48V battery pack and the 3.5 kW motor. We tested the machine with a 30-ton concrete block.
The machine moved smoothly. It stopped accurately. The wireless remote worked from 20 meters away. We recorded the full-load running test video. We sent it to the customer. They approved the quality. We loaded the machine into a 40HQ container. We secured it with steel straps. The container left our factory and headed to the port.
Delivery and Installation: Shipping the Electric Transfer Cart to Ohio
The sea freight took 30 days to reach the Port of New York. Customs clearance took another 4 days. A flatbed truck delivered the machine to the Ohio plant. The plant manager arranged a crane to unload it. The machine was ready for setup.
Our engineer provided remote installation support via video call. The plant’s maintenance team connected the charging station. They checked the battery water level. They tested the forward and reverse functions. The whole setup took one day. There were no major issues.
Performance Data: 60-Day Review of the Factory Automation AGV
The plant started using the machine on the second day. They established a daily routine. Workers load the castings in the morning. The machine runs automatically to the assembly line. It returns empty for the next load.
The route takes 3 minutes. The old forklift route took 15 minutes. The machine operates at 15 m/min on the main straightaway. It slows down to 5 m/min at corners. The battery lasts for 3.5 hours of continuous work. The plant runs two shifts. The team charges the battery during the lunch break. A full charge takes 6 hours. The 1-hour opportunity charge adds enough power for the afternoon shift. Unlike diesel forklifts, it produces zero emissions, keeping the factory air clean.

Implementation Challenges: Overcoming Floor Inclines and Operator Habits
The first week revealed two small challenges. First, the factory floor had a 3-degree incline near the loading dock. The machine struggled slightly with a full 30-ton load. Our engineer adjusted the motor’s torque settings remotely. The machine now handles the slope easily.
Second, the operators needed practice with the remote control. They were used to steering with a wheel. They adapted to the joystick controls in two days. The plant manager reported that the learning curve was very short. The operators prefer the new machine over the old forklifts.
ROI Analysis: Before vs After Results
The customer tracked the data for two months. The results exceeded expectations. Transport time dropped by 80%. The machine saves 4 hours of transport time per shift. The plant reassigned one forklift driver to another department, saving $45,000 annually in labor costs. The factory recorded zero accidents involving material transport. The old forklifts had three minor incidents in the previous year.
| Metric | Old Forklifts | YG Electric Transfer Cart |
|---|---|---|
| Daily Transport Time | 8 hours (2 shifts) | 1.6 hours (2 shifts) |
| Labor Required | 2 full-time drivers | 1 part-time operator |
| Daily Energy Cost | $70 | $2.50 |
| Safety Incidents | 3 per year | 0 |
| Emissions | Diesel fumes indoors | Zero emissions |

Customer Feedback and Next Steps for Factory Automation
The plant manager sent an email after two months. He wrote: “The Electric Transfer Cart has changed our workflow. It is reliable, quiet, and safe. Our workers love the remote control. We are moving parts faster than ever.”
The plant is now planning to expand the system. They want to buy a second unit for the welding department. They also requested a quote for an automated charging station. The maintenance team noted that the heavy-duty frame shows no signs of stress. The paint is intact. The wheels show minimal wear.
Frequently Asked Questions (FAQ) About the Electric Transfer Cart
No. The AGV-30T is a trackless transfer cart. It uses solid rubber wheels and navigates on flat concrete floors without needing rails.
A full charge takes about 6 hours. The machine includes an opportunity charging feature, allowing operators to top up the battery during lunch breaks to extend the run time.
Yes. The motor features adjustable torque settings. As mentioned in the case, we remotely adjusted the torque so it could easily manage a 3-degree incline near the loading dock.
Every machine comes with a 12-month warranty. We provide remote technical support, spare parts shipping, and comprehensive operation manuals.
