SIASUN G-20-30X (G-20-30X)

A tractor that hitches itself to a trailer and tows it away with nobody at the controls: that is the idea behind the SIASUN G-20-30X (G-20-30X). It is a campus delivery mobile robot built for heavy-load towing outdoors, where the work never really stops and the weather does not ask permission.

The product is available through this page, by quotation.

Background

SIASUN and the logic of heavy-load automation

SIASUN is a robotics manufacturer whose mobile robots are used for material transport in factories, warehouses and industrial sites. The G-20-30X belongs to its outdoor tractor family, a line aimed at moving loaded trailers over longer distances than an indoor robot is meant to cover. It is a campus delivery mobile robot, and the heavy-load towing role is what sets it apart from lighter transport vehicles.

Outdoor logistics is a different problem from indoor logistics. Surfaces change, there is no ceiling or wall to navigate against, and sites often have long runs between loading points. A robot for this work has to find its position without relying on fixed indoor landmarks, and it has to keep working through rain, heat and darkness. SIASUN designed the G-20-30X around those demands.

Positioning and key technology

Two ideas define this robot. The first is multi-source perception. The G-20-30X combines 3D lidar, satellite navigation, inertial navigation and vision sensing, and its positioning is built on 3D-SLAM, IMU and RTK navigation. Each source covers for the weaknesses of the others, which supports accurate positioning and intelligent path planning in changing outdoor surroundings.

The second idea is SIASUN's patented automatic hitch/unhitch technology. The tractor and the load trailer couple and separate without a person on site. That removes the slowest and most awkward step of trailer-based transport and turns the tractor and trailers into a flexible system rather than a fixed pairing.

How does the G-20-30X differ from a conventional tractor and trailer?

A conventional tractor and trailer depends on a driver, and on a person to hitch and unhitch at every stop. The G-20-30X replaces both. Its sensor suite lets it localize itself and plan its path, and its automatic hitch/unhitch lets the tractor and the load trailer couple and separate unmanned. A site can therefore stage loaded trailers and let the robot collect them, instead of tying up a vehicle and an operator for every load.

The rated towing weight is 20000/25000/30000 kg, which places the robot firmly in the heavy-load class. The travel speed is 2.2 m/s. Braking is hydraulic and power-assisted, and the drive is rear-wheel, a layout that suits a vehicle built to pull.

Safety is handled in software as well as hardware. The robot offers remote monitoring, sensor self-check, abnormal alarm and abnormal-operation protection, so operators can watch the vehicle and the vehicle can check itself.

Can it work as part of a fleet?

Yes. The vehicles coordinate through advanced communication and integrate with management software, which streamlines logistics processes and raises overall efficiency. Deployment is fast, flexible and scalable, and the robot is meant for around-the-clock, all-weather operation. For a site that expects to add vehicles over time, this matters as much as any single figure in the table.

Who is the SIASUN G-20-30X for?

The robot suits operators who move very heavy loads outdoors on a repeating basis: industrial parks, large production sites, ports and yards, and campuses where material travels between buildings and storage areas. It is also a fit for businesses that want continuous operation without staffing night shifts for tractor work.

Buyers with different loads may find another model in the range closer to their needs. You can compare the SIASUN G-5-6X, the SIASUN G-8-15X and the SIASUN G-40X, and our team will help you match the model to your load.

What is the SIASUN G-20-30X used for?

1. Heavy-load towing: pulls loaded trailers within the rated towing weight of 20000/25000/30000 kg.
2. Campus and park logistics: carries goods between buildings, plants and storage areas on large sites.
3. Unmanned trailer exchange: hitches and unhitches trailers automatically, so loads can be staged and collected.
4. Round-the-clock transport: supports 7*24H all-weather operation for continuous material flow.
5. Outdoor navigation tasks: uses 3D lidar, satellite, inertial and vision sensing to find its way in changing conditions.
6. Fleet-coordinated logistics: works with other vehicles and management software to organize transport jobs.

Frequently Asked Questions

What towing weight does the G-20-30X handle?

The rated towing weight is 20000/25000/30000 kg.

How fast does it travel?

The travel speed is 2.2 m/s.

How does it find its position outdoors?

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

Does it couple to trailers by itself?

Yes. It carries SIASUN's patented automatic hitch/unhitch technology, so the tractor and the load trailer couple and separate unmanned.

Can it run at night and in bad weather?

Yes. It supports 7*24H all-weather operation.

What are the battery and charging details?

Battery and charging details are given with the quotation. Tell us your duty cycle when you ask.

Summary

The SIASUN G-20-30X (G-20-30X) takes the hardest part of trailer logistics, the hitching and the driving, and hands it to a machine. Multi-source perception, rear-wheel drive, hydraulic power-assisted braking and unmanned hitch/unhitch make it a serious tool for heavy outdoor towing, with a rated towing weight of 20000/25000/30000 kg and a travel speed of 2.2 m/s.
