SIASUN G-40X (G-40X)

Moving a very heavy cart across a plant site comes down to one plain question: who is at the drawbar? With the SIASUN G-40X (G-40X) the answer is nobody. This heavy-load towing mobile robot couples to a load cart, tows it and releases it again without a person stepping out of a cab. It is built for factories that have already automated their lines and now want the same discipline in the heavy transport between buildings.

The SIASUN G-40X (G-40X) is available through this page, by quotation.

Background

SIASUN and the G series

SIASUN is a robotics brand with a broad range of mobile robots for industry. The range covers under-ride lift robots, towing robots and the control software that coordinates them. The G-40X sits in the towing family. Sibling versions of the same family exist for other towing duties, among them the SIASUN G-5-6X, the SIASUN G-8-15X and the SIASUN G-20-30X. The G-40X is the version named for a rated towing weight of 40000 kg.

The manufacturer describes it as a heavy-load towing mobile robot made for automotive, lithium battery and 3C electronics manufacturing. These industries move bulky, valuable material between production halls, warehouses and yards, often every hour of the day. The aim is plant-level transfer that is heavy-duty, efficient and flexible, and that lifts the level of heavy logistics automation between workshop and storage.

Key technology: patented hitch and unhitch

The feature that defines this robot is SIASUN's own patented automatic hitch and unhitch technology. The tractor and the load cart couple and separate without staff. This matters because coupling is the step that traditionally keeps a person in the loop, even when the driving itself is automated. Removing it lets the robot run a full cycle: pick up a loaded cart, tow it, set it down and go back for the next one.

The second pillar is sensing. The robot fuses 3D lidar, satellite navigation, inertial navigation and vision sensing for positioning and path planning. The positioning approach is stated as 3D SLAM plus IMU plus RTK navigation. The manufacturer says this suits complex outdoor environments, which is where a 40000 kg tow is most likely to work.

What makes the G-40X different from a driver-operated yard tractor?

A yard tractor with a driver is flexible, but it is tied to a shift pattern and to a person who must climb in and out to couple each trailer. The G-40X is designed to lift that burden. It supports 7*24H all-weather operation, and its hitch and unhitch happen without staff. The cart is handed over and taken on by the robot itself, so the work does not stop for a changeover.

Safety is built into the design as well. The manufacturer lists remote monitoring, sensor self-check, fault alarm and protection against abnormal operation. For a machine pulling up to 40000 kg, a robot that checks its own sensors and raises an alarm when something is wrong is a practical advantage. The service brake is hydraulic power-assisted, a familiar and robust choice for heavy vehicles.

How does the G-40X find its way outdoors?

Outdoor sites are harder than indoor halls. Surfaces change, there are no walls to follow and the weather varies. The G-40X answers with several sources of perception working together. 3D lidar and vision sensing see the surroundings, satellite navigation with RTK gives a position reference, and inertial navigation fills the gaps between updates. Together they feed positioning and path planning.

The robot also coordinates with other vehicles through communication and integrates with management software. That lets a site treat the robots as part of one logistics process instead of single machines, and the manufacturer says this optimizes the logistics flow and improves overall efficiency. Deployment is described as fast, flexible and scalable, so a site can start small and add robots as the transport task grows.

Who is the SIASUN G-40X (G-40X) for?

The G-40X suits manufacturers that move very heavy loads across a plant site on a regular schedule. Automotive plants moving large assemblies, lithium battery producers shifting bulky material, and 3C electronics makers with long routes between buildings are the segments the manufacturer names. Logistics managers who want to run continuously, around the clock and in all weather, will find the 7*24H design relevant.

Buyers whose loads are lighter should look at the smaller siblings, which are made for other towing ranges: the SIASUN G-5-6X, the SIASUN G-8-15X or the SIASUN G-20-30X. For handling that lifts a cart from underneath instead of towing it, the SIASUN P-T1000D and the SIASUN 2000 Kg Under-ride Lift Mobile Robot (P-T2000D) are the products to ask about. Other robots in the same field are listed under Mobile Robots.

What is the SIASUN G-40X (G-40X) used for?

1. Heavy material transfer between workshops: the robot tows loaded carts between production halls at plant level.
2. Automotive manufacturing logistics: large components move from storage to the line without a driver.
3. Lithium battery plant transport: bulky material travels between process areas and warehouses.
4. 3C electronics material flow: long site routes run on a steady, repeatable schedule.
5. Workshop-to-warehouse links: the robot raises the level of heavy logistics automation between production and storage.
6. Round-the-clock outdoor shuttling: the 7*24H all-weather design keeps carts moving across the yard in any shift.

Frequently Asked Questions

What is the rated towing weight of the G-40X?

The rated towing weight is 40000 kg. This is the figure the manufacturer publishes for the G-40X.

How fast does the G-40X travel?

The published travel speed is 2.2 m/s. The manufacturer does not give a separate speed for other load conditions in the sources we hold.

Does a person have to couple the cart?

No. SIASUN's patented automatic hitch and unhitch technology lets the tractor and the load cart couple and separate without staff.

How does the robot navigate?

It uses multi-sensor fusion navigation, combining 3D lidar, satellite navigation, inertial navigation and vision sensing. Positioning is stated as 3D SLAM plus IMU plus RTK.

Can it work at night and in bad weather?

The manufacturer states that it supports 7*24H, all-weather operation. Details such as the operating temperature range are confirmed at quotation.

Can it work with our management software?

Yes. The robot coordinates vehicles through communication and integrates with management software. The integration scope is agreed when the quotation is prepared.

Where can I buy the G-40X and what does it cost?

You can request it through this page, by quotation. The cost depends on your site and configuration, so we give it in the quotation and not as a list figure.

Summary

The question at the drawbar has a clear answer here. The SIASUN G-40X (G-40X) takes the person out of the coupling, the towing and the release, and it pairs a rated towing weight of 40000 kg with multi-sensor fusion navigation, a hydraulic power-assisted service brake and rear-wheel drive. It is aimed at automotive, lithium battery and 3C electronics sites that need heavy transport to run day and night. If that matches your yard, this page is the starting point.
