SIASUN Heavy-Load Mobile Robot (Heavy-load mobile robot)

Some loads do not forgive a clumsy move. A single misjudged turn with a multi-ton fixture can scar a floor, stop a line or put people at risk. The SIASUN Heavy-Load Mobile Robot (Heavy-load mobile robot) is built for exactly that kind of work: it carries the weight, moves it in any direction and stops where it is told to stop.

Background

SIASUN and its heavy-duty lineage

SIASUN has been investing in research and development of heavy-duty mobile robots since 2009. That is a long track record for a segment where many suppliers are still newcomers. Over those years the company has built a family of platforms that spans light-heavy models and very large carriers, and the sources name four versions: the 3T, 5T, 20T and 60T Heavy-Duty Mobile Robot.

The family sits within the wider SIASUN range of industrial and mobile robots, which you can browse in the SIASUN category. Heavy-duty carriers are one part of that range, alongside assembly-line robots and industrial arms.

What counts as a heavy-duty mobile robot

Usually, a load of 5 tons or more is enough to call a mobile robot heavy-duty. SIASUN's platforms can also achieve loads of 10-120 tons, and the maximum loading capacity can reach 200 tons. This is far beyond what a standard warehouse vehicle is designed for, and it changes how the machine is engineered.

The wheel system has to meet two demands at once: it must provide enough load-bearing capacity and driving force, and it must not damage the ground. Most heavy-duty mobile robots also operate in all directions without needing a turning radius. That matters on a crowded factory floor, where a long swing-out turn is simply not possible.

The manufacturer has not published the dimensions, the weight, the battery capacity, the runtime, the charging method, the IP rating, the power supply, the wireless connectivity or the box contents; they are confirmed at quotation.

How does it move such heavy loads so precisely?

Precision at this scale comes from combining a drive system that can steer freely with a navigation method that knows exactly where the vehicle is. The robot can move forward, backward and sideways, and it can spin on the spot. Because most heavy-duty mobile robots of this kind need no turning radius, the vehicle can approach a workstation from whichever direction the layout allows and then align itself without a series of corrective maneuvers.

Navigation is generally by magnetic guidance or by laser. Magnetic navigation follows a defined path and suits fixed, repeatable routes. Laser navigation suits sites where routes may change over time. Which of the two fits your plant is a question for the quotation stage, once the layout and the load are known. With either method, the robot can achieve ± 5mm parking positioning accuracy, which is what makes hand-off to a machine, a fixture or an assembly station dependable.

Speed is deliberately modest. It is generally controlled at around 0.5m/s, which is the sensible pace for a vehicle carrying tons. Slow and steady is the point here, since it keeps the load stable and the surroundings safe. The design follows the ISO3691-4 standard, with safety levels engineered to PLD&E classifications.

Which version matches which load?

The sources name four versions, and each keeps its own figures. The 3T version is rated at a payload capacity of 3 t, the 5T version at 5 t and the 20T version at 20 t. A 60T version is also named, though the sources give no separate figures for it, so its details are confirmed at quotation.

For the 20T version, the sources add three further figures: positioning accuracy of ±10 mm, a lifting height of 80-100 mm and gradeability of 3%. These belong to that version only and should not be read across to the others. The ± 5mm figure is the parking positioning accuracy the family can achieve, and it is stated separately from the 20T version's positioning accuracy.

The practical advice is to choose the version by your heaviest regular load, not by the average. If a single part or fixture is the heaviest thing on your site, that item decides which platform you need.

Who is the SIASUN Heavy-Load Mobile Robot for?

The first group is heavy manufacturers: makers of vehicles, machinery, steel structures and large components, where parts weigh several tons and are moved between stations again and again. A mobile robot replaces the crane booking and the forklift crew for these repeated runs.

The second group is plants that already run automated production and want transport to follow the same rules. The robot can operate independently or be integrated into production management systems, so it can be tied into scheduling rather than left as an isolated machine.

The third group is buyers with loads in the mid-range. If your regular load is closer to 10 tons, the SIASUN 10,000 Kg Heavy-Duty Mobile Robot may be the more direct fit, and it is worth comparing it with this page when you request a quotation. Buyers who need assembly-line support rather than pure transport can also look at the SIASUN Commercial Vehicle Assembly Mobile Robot.

For Caribbean buyers, such as port-side industry, heavy fabrication, power and utility workshops and large maintenance yards, the draw is the same: moving very heavy items safely, without damaging the floor and without a crane every time.

What is the SIASUN Heavy-Load Mobile Robot used for?

1. Moving heavy components between stations. Carry large parts from one stage of production to the next without crane or forklift.
2. Positioning loads for assembly. Stop within ± 5mm parking positioning accuracy so the next process can begin without manual adjustment.
3. Transporting fixtures and tooling. Shift heavy fixtures, dies and molds to the machines that need them.
4. Moving loads in tight spaces. Use sideways travel and spin, with no turning radius, to work through crowded aisles.
5. Feeding production management systems. Integrate the robot so transport orders follow the production plan.
6. Handling very large loads. Use the family's payload range of 10-120 tons, with a maximum loading capacity that can reach 200 tons, for exceptional items.

Pricing and Availability

We do not publish prices for this robot, because each system is configured to a load, a route and a site. Please ask for a quotation and tell us the heaviest load, the navigation method you prefer and the layout of your plant. Delivery, customs and support are arranged together with the quotation. The SIASUN Heavy-Load Mobile Robot is available on this page.

Frequently Asked Questions

What payload can the robot carry?

Heavy-duty mobile robots of this kind can achieve loads of 10-120 tons, and the maximum loading capacity can reach 200 tons. The named versions are the 3T at 3 t, the 5T at 5 t and the 20T at 20 t.

How accurate is the positioning?

The robot can achieve ± 5mm parking positioning accuracy. The 20T version is listed with positioning accuracy of ±10 mm, so the figure depends on the version.

How does the robot navigate?

Navigation methods are generally magnetic navigation or laser navigation. The choice is made together with you, based on your site.

How fast does it travel?

The speed is generally controlled at around 0.5m/s, which is suited to carrying very heavy loads safely.

Does it need space to turn?

No. Most heavy-duty mobile robots of this type operate in all directions without the need for a turning radius. They can move forward, backward and sideways, and they can spin.

Can it connect to our production systems?

Yes. Mobile robots can operate independently or be integrated into production management systems.

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

You can request it through this page, by quotation. The cost depends on the version, the load and the site, so we confirm it in the quotation rather than publish a figure.

Summary

Heavy loads call for care, and this robot is built to supply it: a platform that bears tons, moves in any direction, travels at a measured pace and parks with ± 5mm accuracy. It follows ISO3691-4 and is backed by a manufacturer that has worked on heavy-duty mobile robots since 2009. Several versions exist, from 3 t to 20 t and beyond, so the right one can be matched to your heaviest load. If you are weighing how to move heavy items without the crane and the delay, this page is the starting point.
