SIASUN GCR25-1800-EX (GCR25-1800-EX)

Some jobs in a plant are dangerous not because they are hard but because of where they have to be done. The SIASUN GCR25-1800-EX is a collaborative robot arm built for exactly those places: sites where the air can ignite, poison or scald, and where a person standing at the work point is the risk you would most like to remove.

Background

SIASUN DUCO and the explosion-proof line

The GCR25-1800-EX comes from SIASUN DUCO, a sub-brand of SIASUN that concentrates on intelligent robotics. All of its core components are independently developed, and the sub-brand has broken foreign technology monopolies in several fields. For a buyer, that matters less as a slogan than as a practical point: the company designing the arm also develops the parts inside it.

Within the SIASUN range, this arm belongs to the Explosion-Proof Series. The series holds four collaborative robot models, with load capacities from 10 to 25 kg and arm reaches from 1300 to 2000 mm. The GCR25-1800-EX is the model listed with a 25kg payload and 1800mm reach, which places it at the heavy-load end of the series. The other members are the GCR10-1300-EX, the GCR16-2000-EX and the GCR20-1400-EX.

A collaborative robot for hazardous work

Collaborative robots are usually pictured in clean assembly cells, working beside people without a fence. This series takes the same idea into a harder setting. These robots act as a protective barrier for frontline high-risk workers: they can replace human operators in flammable, explosive, toxic, harmful, high-temperature and high-pressure settings, of the kind found in the petroleum, natural gas and chemical industries.

The arm keeps the traits that make collaborative robots attractive in the first place. Programming is by drag-and-drop teaching, which lowers the usage threshold and makes operation easier. Safety is supported by 16 TUV-certified safety features for human-machine collaboration. Sensing and intelligence come from the integration of 2D/3D vision depth fusion with high-sensitivity force perception and control. On the software side, the arm offers scenario-specific software packages, support for multiple external interfaces, cloud-based robot data monitoring and remote OTA upgrades.

The manufacturer has not published the weight, the explosion-protection rating, the power supply, the power consumption, the robot dimensions, the operating temperature range, the communication interfaces, the I/O interface, the joint ranges and speeds, what is in the box or the required air supply; they are confirmed at quotation.

What makes the GCR25-1800-EX different from the rest of the series?

The clearest difference is capacity. The series spans 10 to 25 kg of load, and this model is the one that carries 25kg. That headroom is useful when the arm has to hold a heavy tool, a gripper with sensors, or a container, and still move with margin. A lighter arm doing the same job runs close to its limit; an arm with more capacity has room for the tool you add later.

The second difference is working radius. At 1800mm of reach, the arm covers a wide area from one fixed base, which means fewer repositioning moves and fewer fixtures around a skid or a valve station. Together with a maximum TCP speed of 2.5m/s and repeatability of ±0.05mm, the figures describe an arm intended for tasks that need both distance and consistency, rather than a compact bench robot.

If your task is lighter or your space tighter, it is worth comparing the sibling pages named in this article. The series was designed so that buyers can match load and reach to the job, and the advantage in load capacity and working radius is what lets the family fit a broader range of applications.

How does the arm support safe work next to people?

Hazardous sites do not become empty simply because a robot arrives. Technicians still inspect, maintain and adjust equipment nearby. That is why the 16 TUV-certified safety features matter: they serve human-machine collaboration, with safety as the focus. The IP class of IP54/IP65 is also stated for this model, which tells you the enclosure is rated against dust and water ingress.

Sensing adds another layer. High-sensitivity force perception lets the arm respond to contact, and 2D/3D vision depth fusion lets it understand what it is working on. For operators, drag-and-drop teach programming keeps setup approachable, so that a plant engineer can teach a task without writing everything from scratch. Remote OTA upgrades and cloud-based data monitoring help keep a deployed arm current and visible without sending someone into the hazardous zone.

Who is the SIASUN GCR25-1800-EX for?

The first segment is operators in petroleum, natural gas and chemical plants, where flammable, explosive or toxic conditions make manual work costly in risk. Those teams want a robot that can take over the repeated, exposed task while people stay at a safer distance.

The second segment is engineering and integration firms that build automation cells for hazardous areas. A six-degree-of-freedom arm with a long reach and a high payload gives them a single platform for many tasks, from handling to inspection support, with scenario-specific software packages to shorten development.

The third segment is safety and operations managers who must justify a robot to a site committee. The TUV-certified safety features and the explosion-proof positioning of the series give them a clear starting point for that discussion. Buyers whose loads are lighter should look at the GCR10-1300-EX or the GCR20-1400-EX, while those who put reach first can review the GCR16-2000-EX.

What is the SIASUN GCR25-1800-EX used for?

1. Replacing operators in hazardous areas. The arm takes over tasks in flammable, explosive, toxic, high-temperature and high-pressure settings.
2. Petroleum and natural gas sites. It suits frontline work in the oil and gas industries, where exposure risk is part of daily operations.
3. Chemical plant tasks. It can handle repeated manual steps in chemical processing where harmful substances are present.
4. Heavy tool and load handling. With a 25kg payload, it can carry demanding tools or items across its 1800mm reach.
5. Vision-guided work. 2D/3D vision depth fusion supports tasks where the arm must see and respond to its workpiece.
6. Force-sensitive operations. High-sensitivity force perception lets the arm work with contact and adjust to it.
