SIASUN GCR20-1400-EX (GCR20-1400-EX)

Most collaborative robots are judged by how gently they can work beside people; heavier industrial arms are judged by how much they can lift and how far they can reach. The SIASUN GCR20-1400-EX asks to be judged by both at once. It is a six-axis arm that carries a maximum payload of 20 kg across a reach of 1,400 mm, yet it is built around safety functions designed for human-machine collaboration and a teaching method that needs no written code. For a plant manager, the question is no longer whether to choose strength or approachability, but how to put the two to work in the same cell.

Robots Europa, based in Dublin, sells the SIASUN GCR20-1400-EX and supplies it to manufacturers, system integrators and research users across the European Union and the DACH region. Robots Europa prepares each quotation, coordinates delivery to the customer's site and remains the point of contact for support once the arm is in service.

Background

SIASUN and its intelligent-robotics line

SIASUN is the brand behind a broad family of robots, from industrial arms to collaborative models. Its work in intelligent robotics is carried by SIASUN DUCO, a sub-brand that has broken foreign technology monopolies in several fields, with all of its core components developed in-house. For a buyer, that lineage matters less as a slogan than as a practical point: a manufacturer that designs its own core components controls the design of the arm from end to end, which is relevant to long-term spares and support conversations.

Positioning within the EX versions

The sources name three versions in this family: the GCR10-1300-EX, the GCR16-2000-EX and the GCR20-1400-EX described here. Within that group, the GCR20-1400-EX combines a 20 kg payload with a compact working envelope of 1,400 mm. Its two defining technologies are a set of 16 TUV-certified safety functions aimed at human-machine collaboration and drag-and-drop teaching programming, which lowers the threshold for operation and makes the arm simpler to use.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation. The manufacturer has not published the weight of the arm, its mounting footprint, the package contents, the explosion-proof rating of the arm or its certifications; Robots Europa confirms each of these at quotation.

What does a 20 kg payload mean for a collaborative arm?

Payload is the figure that decides which jobs an arm can take on, and it has to cover everything mounted at the wrist: the gripper or tool, any sensor, cabling and the part itself. With a maximum payload of 20 kg, the GCR20-1400-EX leaves room for substantial end effectors and heavier workpieces, which is where many lighter collaborative arms reach their limit. A vacuum gripper handling cartons, a twin-jaw gripper for machine tending or a power tool for finishing work all consume part of that budget before the part is picked up.

The 1,400 mm reach defines the radius in which that payload is put to use. It is long enough to serve a pallet, a conveyor and a machine door from a single mounting point in many cell layouts, while keeping the arm compact enough to sit within an existing line. Combined with a repeatability of ±0.05 mm, the arm returns to taught positions consistently, which is what assembly, insertion and placement tasks depend on. A maximum TCP speed of 2.2 m/s shows how quickly the tool centre point can travel when the application and the risk assessment allow it; in collaborative operation, speeds are normally limited by the safety configuration rather than by the arm's maximum.

Six degrees of freedom give the wrist full freedom of orientation, so the tool can approach a part from an angle rather than only from above. The IP class of IP54/IP65 is relevant where dust or water is present in the working environment, and it should be read together with the site's own requirements when the cell is specified.

How is the SIASUN GCR20-1400-EX programmed and kept safe?

Drag-and-drop teaching means that an operator can guide the arm by hand to the positions a task needs and record them, instead of writing every move as code. For a production team without a dedicated robot programmer, that changes the economics of automation: a new product variant or a revised cell layout can be taught on the shop floor by the people who know the process best. The method lowers the threshold for use, and in practice it shortens the time between installation and the first useful cycle.

Safety is addressed through 16 TUV-certified safety functions designed for human-machine collaboration. Collaborative operation still requires a risk assessment of the complete application, including the tool, the part and the surrounding equipment, and the safety functions are the means by which the arm is configured to meet the limits that assessment sets. Robots Europa can discuss the intended application when preparing the offer, so that configuration questions are raised early rather than at commissioning.

Who is the SIASUN GCR20-1400-EX for?

The arm suits manufacturers who want to automate heavier handling tasks without fencing off a large area of the shop floor, and who value being able to reteach the robot in-house. Small and medium-sized producers moving into automation for the first time will find the teaching method approachable, while larger plants can use the arm to relieve operators of repetitive lifting at stations where people and the robot share space.

System integrators building cells for clients form a second group: a single arm with a 20 kg payload and 1,400 mm reach covers a wide range of end-of-line and machine-side applications. Research institutes and training centres working on human-robot collaboration are a third group, for whom the combination of a meaningful payload and collaborative safety functions offers realistic test conditions.

Where a task calls for a different balance of payload and reach, the sibling versions are worth comparing. The SIASUN GCR10-1300-EX (GCR10-1300-EX) and the SIASUN GCR16-2000-EX (GCR16-2000-EX) belong to the same family and are presented on their own pages. Buyers who wish to survey the wider range can browse the Robot Arms and Industrial Robots categories.

What is the SIASUN GCR20-1400-EX used for?

1. Machine tending — loading and unloading CNC machines, presses or moulding machines with blanks and finished parts.
2. Palletising and depalletising — stacking cartons or bags at the end of a line within a compact footprint.
3. Material handling — transferring parts between conveyors, fixtures and workstations.
4. Assembly — placing and inserting components where consistent, repeatable positioning is required.
5. Finishing work — carrying tools for grinding, polishing or deburring along taught paths.
6. Inspection and testing — presenting parts to cameras or test stations in a repeatable sequence.

Frequently Asked Questions

What is the maximum payload of the SIASUN GCR20-1400-EX?

The maximum payload is 20 kg. This figure includes the tool mounted at the wrist as well as the part being handled.

How far can the arm reach?

The reach is 1,400 mm. The usable working area in a given cell also depends on the mounting position and the surrounding equipment.

How precise is the GCR20-1400-EX?

Its repeatability is ±0.05 mm, meaning the arm returns consistently to the positions it has been taught.

Does the arm need specialist programming skills?

No. It uses drag-and-drop teaching programming, so operators can guide the arm by hand and record positions rather than writing code.

What safety features does it have?

The arm has 16 TUV-certified safety functions designed for human-machine collaboration. A risk assessment of the complete application is still required before collaborative operation.

Which IP class does the GCR20-1400-EX carry?

The IP class is IP54/IP65. Buyers planning use in dusty, wet or hazardous areas should state these conditions in their quotation request.

Summary

The SIASUN GCR20-1400-EX removes the usual trade-off between a strong arm and an approachable one. A 20 kg payload, 1,400 mm reach and ±0.05 mm repeatability let it take on substantial handling and placement tasks, while 16 TUV-certified safety functions and drag-and-drop teaching keep it close to the people who run the line. Robots Europa supplies, delivers and supports it across the EU and the DACH region. For anyone weighing strength against collaboration on the shop floor, this page is the starting point.
