SIASUN Industrial Robot Arm with 3053 mm Reach, 120kg Max Payload, 6 DOF (SR210-120/3.05)

Most heavy robots make you choose: carry a lot, or reach far. The SIASUN Industrial Robot Arm with 3053 mm Reach, 120kg Max Payload, 6 DOF (SR210-120/3.05) is built for the cell where you cannot give up either one. A fixture sits at one end, a conveyor or machine at the other, and the arm has to span the gap while holding a heavy tool or part.

The product is available through this page, by quotation.

Background

SIASUN and the lineage of this arm

SIASUN is a Chinese manufacturer of industrial robots, and its arms are sold into factory automation work such as handling, welding and machine tending. The SR210 family covers several versions: SR210-120/3.05, SR210A-210/2.65 and SR210A-210/3.05-DW. The numbers in each code describe a different combination of payload and reach, which is why it pays to read the full model code before ordering.

This page covers the SR210-120/3.05 only. Every figure below belongs to this version and is not borrowed from its siblings. If a project needs a different balance of carrying capacity and span, the SIASUN Industrial Robot Arm (SR210A-210/3.05-DW) is the sibling version to ask about when you request your quotation.

Where the SR210-120/3.05 sits

This is a six-axis articulated arm, the layout most buyers picture when they think of an industrial robot. Six axes let the tool approach a workpiece from many angles, which is what welding, loading and assembly work demands. Within the broader range, the arm belongs with the large-payload robots, and you can compare it with others in the Large Payload category or across the wider Robot Arms range.

The arm is run by the SRC E5 controller and is installed upright. Both details shape how a cell is laid out, from the floor plan to the position of the cabinet, and we return to them below.

What makes the SR210-120/3.05 different from other heavy robots?

The difference is the pairing of a 120 KG payload with a 3,053 mm maximum working radius. Many heavy arms are compact, because a short arm is stiff and carries its load close to the base. This version accepts a longer arm so that it can serve a wider area from a single mounting position. For a buyer, that can mean one robot covering what might otherwise need a second robot, a track or a repositioned fixture.

The trade-off is simple to state. A longer reach means a bigger envelope to plan around, and the load is carried further from the base. Add up the gripper or torch together with the part and weigh the total against the 120 KG rating, and lay out the cell against the full radius.

Repeatability is ±0.1 mm. For heavy handling, welding and loading, that is the figure to weigh against how closely your fixtures and parts are located. If your process needs tighter positioning, tell us at the start so the right version is quoted.

How do the controller and installation affect planning?

The SRC E5 controller runs the arm, and the power capacity is 8 KVA. Electrical planning for the cell starts from that figure, and your electrician will want it early.

The arm is installed upright, meaning it stands on its base. A heavy robot with a long reach calls for a solid foundation, so plan the plinth with care. Keep guarding and operator access outside the full 3,053 mm radius, and place the controller cabinet where it can be reached without entering the working area.

Who is the SR210-120/3.05 for?

The first buyer is the plant that handles heavy parts across a wide cell: castings, fabricated assemblies, tooling or large fixtures. A long reach with a 120 KG rating suits stations where parts move from a pallet or conveyor to a machine some distance away.

The second is the fabrication shop that needs to position a heavy welding tool over big workpieces. Reach reduces the number of times a part must be turned or moved. The third is the integrator, who needs an arm with a clear payload, radius and controller to design a cell around.

If your parts are heavier than this version is rated for, ask us about the SR210A-210/3.05-DW version. If you need a different kind of robot altogether, the Robot Arms category lists the alternatives.

What is the SR210-120/3.05 used for?

1. Heavy material handling. Moving large or heavy parts between stations over a wide area.
2. Machine loading and unloading. Feeding machine tools and presses where the robot has to reach across or around the machine.
3. Welding. Carrying a welding tool over large fabrications in a fixed cell.
4. Palletizing and depalletizing. Stacking heavy goods where a long reach covers more pallet positions.
5. Assembly of large components. Placing heavy sub-assemblies into a main structure.
6. Fixture and part transfer. Moving workpieces between fixtures, conveyors and inspection points.

Frequently Asked Questions

What payload does the SR210-120/3.05 carry?

The payload capacity is 120 KG. Remember to count the tool as well as the part.

How far can the arm reach?

The maximum working radius is 3,053 mm.

How precise is it?

Repeatability precision is ±0.1 mm.

Which controller does it use?

It uses the SRC E5 controller, with a power capacity of 8 KVA.

How is the arm installed?

It is installed upright, standing on its base.

What if my parts are heavier than 120 KG?

Ask us about the SR210A-210/3.05-DW version when you request your quotation. It is a different version with its own ratings.

Where can I buy the SR210-120/3.05 and what does it cost?

You can request it through this page. The cost is given in a quotation that also covers delivery, customs and support, so no price is printed here.

Summary

The SR210-120/3.05 answers a common problem in heavy handling: a load that must be carried and a gap that must be crossed. Its 120 KG payload, 3,053 mm radius, ±0.1 mm repeatability, SRC E5 controller and upright installation define the fit. When you are ready to plan a cell around it, this page is the starting point.
