SIASUN 20T Heavy-Duty Mobile Robot (20T Heavy-Duty Mobile Robot)

Twenty tonnes is the point where a plant stops asking whether a load can be moved and starts asking how many people, cranes and floor markings the move will take. The SIASUN 20T Heavy-Duty Mobile Robot answers that question with a single self-driving platform that carries the load, turns in place and stops where the process needs it.

The product is available through this page, by quotation.

Background

The SIASUN heavy-duty family

SIASUN builds its heavy-duty mobile robots as one series. The series covers capacities from 3 t to 120 t, and the sources name seven versions: 3T, 5T, 10T, 20T, 30T, 60T and 80T. The 20T sits in the middle of that range. It is heavy enough for large assemblies and tooling, yet it is not the largest platform in the family.

Buyers who already know the lighter versions will recognize the approach. A low platform goes under or beside the load, lifts it by a small amount and carries it along a defined route. If you want to compare neighbors, the SIASUN 10,000 Kg Heavy-Duty Mobile Robot and the SIASUN 30T Heavy-Duty Mobile Robot are the two closest steps on either side. The whole group is also gathered under Heavy Duty Mobile Robots.

Positioning and key technology

The 20T is meant for places where heavy loads move on a repeating pattern: shop floors, assembly halls, port yards and process plants. Its wheel system is optimized to balance load capacity and driving performance while protecting the floor, which matters when a 20 t load crosses the same concrete again and again.

The platform supports omnidirectional movement with zero turning radius. In a crowded hall, that means a vehicle can rotate where it stands instead of sweeping a wide arc. It can also work alone or as part of a group, because multi-robot coordination and single-robot operation switch seamlessly. For uneven or demanding work areas, the sources describe obstacle crossing and stable travel for harsh processes.

What makes the 20T different from the other versions?

The most obvious difference is capacity. The 3T, 5T and 10T versions serve lighter loads, while the 30T, 60T and 80T versions take on much heavier ones. The 20T is the step for buyers whose loads have outgrown the 10 t class but do not call for the larger platforms. Choosing the right class matters because a platform sized close to the real load is easier to fit into an existing layout.

The figures in this article belong to the 20T only. The lifting height of 80-100 mm, the positioning accuracy of ±10 mm and the gradeability of 3% are stated for this version, and we do not carry them over to its siblings. If your load sits near a class boundary, ask for the datasheet of the neighboring version as well, and compare them side by side at quotation.

What the versions share is the way of working: a floor-protecting wheel system, omnidirectional movement, several navigation options and the ability to run singly or in coordinated groups.

How does the 20T find its way and stay safe?

Three navigation methods are listed: SLAM, magnetic guidance and color-tape guidance. In practice this gives a plant a choice. A site that wants minimal change to its floor can lean on SLAM. A site that already has magnetic or taped routes can keep them. Whichever method is used, the stated positioning accuracy is ±10 mm, which is useful where a load must meet a fixture, a cradle or a docking station.

Safety protection consists of an emergency stop, an audible and visual alarm and non-contact anti-collision. The alarm tells people nearby that a heavy vehicle is moving, and the anti-collision function acts before contact is made. With loads of this size, that order of events is the one that counts.

On the route itself, the 3% gradeability describes the slope the platform can handle. Together with obstacle crossing and stable travel for harsh processes, it shows that the design expects real factory floors rather than perfectly flat ones. When several robots share a hall, multi-robot coordination lets them work as a group, and any one of them can return to single operation without a restart of the concept.

Who is the SIASUN 20T Heavy-Duty Mobile Robot for?

The first group is heavy manufacturers: aerospace and shipbuilding yards, automotive and construction machinery plants, and steel, metallurgy and other heavy industry. They move large fixtures, structures and workpieces between stations, and they gain from replacing crane scheduling with a vehicle that follows a route.

The second group is port and container logistics and the new energy and energy storage sector. Here, bulky units must travel between production, testing and staging areas, often with little room to maneuver. Zero turning radius helps in exactly these tight spaces.

The third group is plant engineers who are planning a gradual rollout. They can begin with one platform, add more later and run them as a coordinated group. Buyers with lighter loads should look at the SIASUN 5T Heavy-Duty Mobile Robot, and those with much heavier loads at the SIASUN 60T Heavy-Duty Mobile Robot. Factory planners may also browse the wider factory robots range.

What is the SIASUN 20T Heavy-Duty Mobile Robot used for?

1. Port and container logistics: moving heavy units between yard, staging and handling areas along set routes.
2. New energy and energy storage: carrying large, heavy equipment between production and test stations.
3. Aerospace and shipbuilding: transporting big assemblies and structures through the halls where they are built.
4. Automotive and construction machinery manufacturing: shifting heavy components and tooling from one process step to the next.
5. Steel, metallurgy and heavy industry: handling heavy material in demanding processes where stable travel is needed.
6. Coordinated fleet transport: several robots working together on one load or splitting the work, then returning to single operation.

Where can I buy the SIASUN 20T Heavy-Duty Mobile Robot and what does it cost?

You can buy it through this page by requesting a quotation. The cost depends on your configuration and delivery, so it is given in the quotation and not listed here.

Summary

Moving twenty tonnes is usually a matter of cranes, crews and wide turning paths. The 20T replaces much of that with one platform that carries 20 t, lifts it 80-100 mm, positions within ±10 mm and turns on the spot. It navigates by SLAM, magnetic guidance or color-tape guidance, protects people with an emergency stop, alarms and non-contact anti-collision, and can join a coordinated group when the work grows. If that matches your plant, this page is the starting point.
