SIASUN GCR12-1300 (GCR12-1300)

Every robot cell is a compromise between how far the arm has to reach and how much floor space it is allowed to take. The SIASUN GCR12-1300 (GCR12-1300) handles that compromise with 1300mm of reach and a 12kg maximum payload, from an arm with a net weight of 37.8kg that can be installed in any direction. It can be mounted on the floor, on a wall, overhead or on a pedestal beside a machine. For production engineers in electronics and automotive plants, this is a collaborative arm that fits the space already available, so the layout does not have to be redesigned around it.

Robots Europa, based in Dublin, supplies the SIASUN GCR12-1300 to manufacturers, system integrators and research groups throughout the EU and the DACH region. We prepare each quotation for the intended application, arrange delivery to your site and remain your point of contact for technical support once the arm is in service.

Background

SIASUN and the DUCO sub-brand

SIASUN is one of the established names in Chinese industrial automation. Its collaborative robots are developed under SIASUN DUCO, a sub-brand of SIASUN dedicated to intelligent robotics. SIASUN DUCO develops all of its core components independently, and in several fields it has broken what were previously foreign technology monopolies. For a buyer, this vertical integration matters. The joints, drives and control electronics in a GCR arm come from the same engineering organisation that designs the arm, so there is one technical lineage behind the whole robot.

The GCR range and where the GCR12-1300 sits

The GCR family is a range of six-axis collaborative arms built on a common design language and offered in several versions: GCR3-618, GCR5-910, GCR7-910, GCR10-1300, GCR12-1300, GCR16-960, GCR16-2000, GCR20-1400, GCR25-1800 and GCR30-1100. Each model number combines a payload class with a reach. The GCR12-1300 pairs the 12kg class with a 1300mm working radius. SIASUN describes the arm as having a lightweight construction and a small footprint, and names the 3C sector (computer, communication and consumer electronics) and the automotive industry as the fields it is particularly well suited to. Both sectors have frequent product changes, tight cell layouts and staff working close to the automation, which is the setting collaborative robots were designed for.

What does 1300mm of reach mean for a cell layout?

Reach decides how many stations a single arm can serve. With a 1300mm radius, the GCR12-1300 can be placed between a conveyor and a machine, or between two fixtures, and work across both without a linear axis. Because it can be installed in any direction, the arm does not need a dedicated floor plinth. It can be mounted on a wall or overhead, which leaves the floor clear for operators, carts and other equipment. This is the practical meaning of a small footprint: the robot takes up the space of its mounting point, and its working envelope does the rest.

Payload and precision complete the picture. A 12kg maximum payload covers the combined weight of the end effector and the part. That leaves room for heavier grippers, screwdriving units or vision heads that lighter arms cannot carry together with a workpiece. A repeatability of ± 0.03mm means the tool returns to a taught point closely enough for fitting, insertion and fastening tasks. Where cycle time matters, the arm reaches a maximum TCP speed of 3.8m/s and a maximum straight-line speed of 1.5m/s. The base joint J1 rotates through ±360° at 180°/s, so the arm can turn to a station behind it without retracing its path.

How does the GCR12-1300 connect to an existing production line?

Integration is often where a cobot project gains or loses time, and the GCR12-1300 is designed to fit into common factory infrastructure. On the network side, it supports Tcp/Ip, Modbus/Tcp, Profinet and Ethernet/Ip. These cover the controller ecosystems most European plants already run, so the arm can exchange signals with an existing PLC without a protocol gateway. At the flange, the tool interface follows GB/T 14468.1-50-4-M6, equivalent to ISO 9409-1. Standard grippers and tool changers that follow the ISO pattern can therefore be fitted directly. The end joint I/O is specified as 2 Dig I/O,24V,0.6A, so simple tools can be switched without extra cabling along the arm.

Power and environment are equally straightforward. The arm runs from a 100-240VAC 47-63Hz 10A supply, and its typical power consumption is 500W. It operates in ambient temperatures from -10°C to 50°C and is rated IP54/IP65. The precise protection class for each part of the system is confirmed against the datasheet with your quotation. At 37.8kg net, the arm can be moved between cells, which suits plants that redeploy automation as product mixes change.

Who is the SIASUN GCR12-1300 for?

The clearest fit is the 3C electronics sector, where assemblies change often, parts are small and accurate, and operators work at the same benches as the automation. The second group is automotive production and its supplier base, where a collaborative arm can take over repetitive handling, fastening or machine-loading tasks next to existing lines. System integrators building cells for either sector will find the standard tool flange and the choice of fieldbus protocols useful when they standardise a design across several customer sites. Universities and research laboratories that need a mid-sized six-axis arm for automation studies are also a natural audience.

Not every task suits the 12kg class. If the required reach is the same but the tooling is lighter, the SIASUN Collaborative Robot Arm (GCR10-1300) is worth comparing. Compact benchtop work may be better served by the SIASUN GCR5-910. Heavier payload classes are covered by the SIASUN Collaborative Robot (GCR16-960) and the SIASUN Collaborative Robot (GCR20-1400). Robots Europa compares the datasheets with you before you commit. The complete range is listed in our Cobots category.

What is the SIASUN GCR12-1300 used for?

1. Electronics assembly – placing and fitting components on 3C production lines where accuracy and frequent changeovers matter.
2. Automotive component handling – moving parts between fixtures, conveyors and test stations alongside line workers.
3. Machine tending – loading and unloading CNC machines, presses or test rigs from a wall or overhead mounting.
4. Screwdriving and fastening – carrying a screwdriving unit and returning to each fastening point with consistent accuracy.
5. Vision-guided inspection – positioning a camera or sensor head repeatably around a workpiece for quality checks.
6. End-of-line packing – picking finished goods into trays, cartons or carriers at the end of a production cell.

Frequently Asked Questions

What payload can the SIASUN GCR12-1300 carry?

The arm has a maximum payload of 12kg. This figure has to cover both the end effector and the workpiece, so the tool weight should be included when sizing the application.

How precise is the GCR12-1300?

Its repeatability is ± 0.03mm, which suits fitting, insertion and fastening tasks that require the tool to return accurately to a taught position.

Can the arm be mounted on a wall or ceiling?

Yes. The GCR12-1300 can be installed in any direction, so floor, wall, overhead and angled mountings are all possible.

Which industrial networks does it support?

The arm communicates over Tcp/Ip, Modbus/Tcp, Profinet and Ethernet/Ip. This lets it connect to the PLCs and line controllers used in most European plants.

Will my existing grippers fit the tool flange?

The tool interface follows GB/T 14468.1-50-4-M6, equivalent to ISO 9409-1. End effectors built to that pattern can be fitted directly, and the digital I/O at the end joint can switch simple tools.

What power supply does the GCR12-1300 need?

It runs from a 100-240VAC 47-63Hz 10A supply and has a typical power consumption of 500W. This is a standard single-phase connection rather than a dedicated industrial feed.

Where can I buy the SIASUN GCR12-1300 and what does it cost?

Robots Europa supplies the GCR12-1300 to customers across the EU and the DACH region. Pricing depends on the configuration and the scope of delivery, so we provide it in a written quotation, which you can request on this page.

Summary

The SIASUN GCR12-1300 settles the usual trade-off between reach and floor space without forcing the cell to be built around it. A 1300mm working radius, a 12kg maximum payload and ± 0.03mm repeatability come in an arm that weighs 37.8kg net and can be installed in any direction. It connects to existing lines through four common industrial protocols and an ISO-equivalent tool flange. SIASUN DUCO develops the arm's core components itself and aims it at electronics and automotive production. Robots Europa quotes, delivers and supports it from Dublin for customers across the EU and the DACH region.
