SIASUN 3T Heavy-Duty Mobile Robot

A conveyor line stays where it was bolted down, while a production plan rarely does. The SIASUN 3T Heavy-Duty Mobile Robot answers that mismatch: a driverless platform for heavy loads that follows a route you can change, rather than a fixed path you must live with. It is the entry point of a series built for loads that people and light trucks cannot handle comfortably.

The product is available through this page, by quotation.

Background

SIASUN and the heavy-duty series

SIASUN builds mobile robots for industrial logistics, and its heavy-duty family is aimed at the hardest transport jobs on the factory floor. The family covers a load range of 3 to 120 t. The 3T is the lightest model in that range, and the versions named for this series are 3T, 5T, 10T, 20T, 30T, 60T and 80T.

The idea behind the family is that one design philosophy can scale from a few tonnes to very large loads. The wheel system is optimized to balance carrying capacity and traction while protecting the floor. That matters in plants where the floor is a long-term asset, such as a finished concrete slab in a production hall or a coated surface in an assembly area.

Positioning and key technology

The series supports omnidirectional motion with zero turning-radius constraints. In practical terms, a platform that can move this way is easier to place in tight aisles, at workstations and in confined transfer points than a vehicle that must swing wide to turn. The series also integrates several navigation options, including magnetic guidance and laser-based navigation, for accurate positioning and path planning.

For the 3T, the navigation methods are SLAM, magnetic guidance and color-tape guidance. This gives a buyer a choice. A plant that wants a simple, visible, low-change route can use tape or magnetic guidance. A plant that expects layouts to evolve can look at SLAM. The series also handles terrain adaptation, with obstacle crossing and stable travel for diverse processes, and it supports both multi-robot coordination and single-robot operation, with seamless switching between the two.

Technical Specifications

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

The manufacturer has not published the dimensions, the weight, the travel speed, the battery type and capacity, the runtime and charging time, the IP rating, the drive configuration, the operating temperature or what is in the box; they are confirmed at quotation.

What makes the 3T different from the larger versions?

The most obvious difference is the load. The 3T carries 3 t, and the series climbs from there through 5T, 10T, 20T, 30T, 60T and 80T. If your heaviest regular transfer is around three tonnes, stepping up to a bigger version means paying for capacity you do not use. If your loads vary or are expected to grow, the SIASUN 5T Heavy-Duty Mobile Robot or the SIASUN 10,000 Kg Heavy-Duty Mobile Robot gives more headroom.

Every figure on this page belongs to the 3T alone. The larger versions have their own specifications, and nothing here should be read across to them. The series-level features, such as omnidirectional motion, the wheel system and the two operating modes, describe the family as a whole.

How does the 3T keep a heavy load under control?

Safety and accuracy are the two things a plant manager asks about first when a heavy load moves without a driver. For safety, the 3T lists an emergency stop, an audible and visual alarm, and non-contact anti-collision. The alarm warns people nearby, the anti-collision function reacts without touching an obstacle, and the emergency stop gives staff a direct way to halt the platform.

For accuracy, the positioning figure is ±10 mm. That is useful when a load must be set down at a station, a fixture or a rack position repeatedly. Lifting height is listed at 100 mm, which suits a platform that raises a load just clear of its support before carrying it. Gradeability is 3%, so a route with a gentle slope can be considered, though a steeper route should be discussed before any order.

Who is the SIASUN 3T Heavy-Duty Mobile Robot for?

The 3T suits manufacturers and logistics operators who have moved past manual handling but do not need a very large platform. Plants that move tooling, assemblies, battery modules, castings or other loads in the three-tonne class are the natural fit. So are operations that want to start with one robot, learn from it, and then add more under multi-robot coordination.

Buyers in these sectors named for the series will recognize the use: port and container logistics, new energy and energy storage, aerospace and shipbuilding, automotive and construction machinery manufacturing, and steel, metallurgy and heavy industry. In the Caribbean, shipyards, port-side workshops, energy facilities and manufacturing plants face the same need to move heavy items safely and repeatably with limited labor.

If your loads run heavier, look at the 5T or at larger versions in the Heavy Duty Mobile Robots category. If you are comparing automation across the plant, the Factory Robots category gives the wider picture.

What is the SIASUN 3T Heavy-Duty Mobile Robot used for?

1. Production-line transfer. Moving heavy work-in-process between stations without a forklift or a driver.
2. Port and container logistics. Handling heavy items in the yard and workshop areas of a logistics operation.
3. Energy equipment handling. Carrying heavy components in new energy and energy storage manufacturing.
4. Shipbuilding and aerospace. Positioning large sub-assemblies where careful, accurate placement matters.
5. Machinery manufacturing. Moving heavy parts in automotive and construction machinery plants.
6. Heavy industry. Supporting steel and metallurgy processes that need steady, repeatable transport of heavy loads.

Summary

A fixed conveyor commits you to one layout, while a mobile platform lets the plan change. The SIASUN 3T Heavy-Duty Mobile Robot brings that flexibility to loads of 3 t, with ±10 mm positioning, three navigation methods and a clear set of safety functions.
