SIASUN G-8-15X (G-8-15X)

A heavy trailer does not care whether it is Tuesday noon or Sunday midnight, and neither should the tractor that moves it. The SIASUN G-8-15X (G-8-15X) is an industrial park delivery mobile robot built around that idea: a driverless tractor that finds its trailer, hitches on, hauls the load across open ground and lets go again, with no one in the cab.

The product is available through this page, by quotation.

Background

The company behind the robot

SIASUN was founded in 2000 and is headquartered in Shenyang, China. The company works in robotics and automation, and its mobile robots range from under-ride lift vehicles to outdoor tractors. The G-8-15X belongs to the outdoor towing line, where the job is moving trailers in the open air rather than carrying a shelf across a clean factory floor.

That lineage matters to a buyer in practical terms. Outdoor heavy-load transport is a different problem from indoor material handling, and a vehicle designed for it has to be judged on how it finds its way, how it brakes and how it connects to the load. Those are the areas where the G-8-15X sets out its specification.

Positioning and key technology

The G-8-15X is classed as an Industrial Park Delivery Mobile Robot. Its navigation is multi-sensor fusion, combining 3D LiDAR, GNSS/RTK satellite positioning, inertial navigation and vision sensors. Positioning rests on 3D SLAM, an IMU and RTK, which together give high accuracy. The idea is that no single sensor carries the whole burden: where satellite reception weakens near a large building, the other sources continue to support localization, and path planning works from the combined picture.

The second pillar is SIASUN's patented automatic coupling and decoupling technology. The tractor and the trailer dock and separate fully autonomously. That removes the person who would otherwise walk out to the trailer, pin the coupling and walk back, and it is what turns a towing vehicle into a complete transport solution rather than a driverless engine that still needs a helper.

The robot is fast, flexible and scalable, with 7×24 all-weather running. It adds fleet coordination and software integration to optimize logistics efficiency, so that several vehicles can work as a system tied into the site's wider software rather than as isolated machines.

Technical Specifications

Specifications as published by the manufacturer; confirmed against the datasheet at quotation.

The manufacturer has not published the dimensions, the vehicle weight, the battery capacity and type, the charging time, the runtime, the IP rating, the positioning accuracy, the gradeability, the operating temperature, the turning radius, the power rating, the wireless connectivity, the safety certifications or the contents of the box; they are confirmed at quotation.

What makes the G-8-15X different from a conventional site tractor?

A conventional yard tractor needs a driver, and a driver means shifts, breaks and handovers. The G-8-15X replaces the cab with a perception stack and a planning system. Its multi-sensor fusion navigation draws on 3D LiDAR, satellite positioning with RTK, inertial navigation and vision, so the vehicle knows where it is and plans a path without a person steering.

The second difference is the hitch. Because coupling and decoupling are automatic, the tractor can leave one trailer and collect another without human help. For a site that runs several trailers on a loop, this is the step that normally ties up a worker, and here it is part of the vehicle's own routine.

The third difference is the way the machine is meant to be operated. Remote monitoring, self-check, alarms and abnormal-operation protection are part of its safety design, and fleet coordination with software integration lets it work inside a logistics system rather than beside it. The result is a towing vehicle that runs around the clock and in all weather, which is exactly where a driver-based operation is most expensive and least comfortable.

How should the four towing ratings be read?

The G-8-15X is listed with rated towing capacities of 8000, 10000, 12000 and 15000 kg. These ratings are the range for this model, and no separate speeds or other figures are given for each rating, so the travel speeds in the table, 2.2 m/s without load and 1.5 m/s with full load, stand for the model as a whole. Which rating suits a given site is settled when we prepare your quotation.

For buyers who want to compare this model with others in the SIASUN family, the SIASUN G-5-6X and the SIASUN G-20-30X are available for review, and we are glad to talk through the differences with you.

Who is the G-8-15X for?

The first group is industrial parks and large manufacturing sites where finished goods, castings, components or containers travel between buildings over open roads. These sites often have a fixed set of routes, repeated all day, which is the kind of work an autonomous tractor does well.

The second group is logistics operators who run trailers between yards, docks and storage areas and want the work to continue through the night and through poor weather. The 7×24 all-weather operation and fleet coordination suit this buyer well.

The third group is engineering and operations teams that already run software to manage their logistics. Software integration and fleet coordination mean the robot can be placed under that management instead of requiring a separate process. Teams planning a wider fleet may also want to look at the SIASUN Mobile Robot Transport Control System, and our Logistics Robots and Mobile Robots categories show what else is available.

What is the G-8-15X used for?

1. Trailer shuttling between buildings: the tractor collects a loaded trailer at one dock and delivers it to another across the park.
2. Heavy-load outdoor transport: goods in the 8 to 15 ton class are moved over open ground without a driver.
3. Round-the-clock logistics: 7×24 operation keeps material moving through night shifts and in all weather.
4. Unattended hitching: automatic coupling and decoupling remove the manual connection step at each stop.
5. Fleet-based material flow: several vehicles are coordinated and linked to site software to improve logistics efficiency.
6. Remote-supervised operation: operators watch the vehicle through remote monitoring, with alarms and protection when something abnormal occurs.

Frequently Asked Questions

What towing capacities does the G-8-15X offer?

The rated towing capacity is listed as 8000, 10000, 12000 and 15000 kg. We settle the rating that fits your site with the quotation.

How fast does it travel?

The no-load travel speed is 2.2 m/s and the full-load travel speed is 1.5 m/s.

How does the robot find its way outdoors?

It uses multi-sensor fusion navigation, combining 3D LiDAR, GNSS/RTK satellite positioning, inertial navigation and vision sensors. Positioning is based on 3D SLAM, an IMU and RTK.

Does it need a person to connect the trailer?

No. SIASUN's patented automatic coupling and decoupling lets the tractor and trailer dock and separate fully autonomously.

Can it work at night and in bad weather?

The robot runs 7×24 in all weather. Ask us about the IP rating and operating temperature when you request your quotation.

What safety functions does it have?

Its safety design includes remote monitoring, self-check, alarms and abnormal-operation protection. Service braking is hydraulic and power-assisted.

Where can I buy the G-8-15X and what does it cost?

The G-8-15X is available through this page by quotation. The cost depends on the towing rating and the configuration you need, so please send us your requirements and we will reply with a quotation.
