The SIASUN GCR25-1800-EX carries the highest payload in SIASUN's explosion-proof collaborative robot series: 25 kg at a 1800 mm reach, at the top of a four-model family covering 10 to 25 kg and 1300 to 2000 mm. Like its siblings, it acts as a protective barrier for frontline workers, taking over tasks in flammable, explosive, toxic, high-temperature, and high-pressure environments found throughout the petroleum, natural gas, and chemical industries. The combination of high load capacity and a long working radius broadens the range of jobs it can absorb, while the platform keeps the collaborative essentials of safe operation, ease of use, rapid deployment, and low power consumption.

Technically, the six-axis arm delivers ±0.05 mm repeatability, TCP speeds up to 2.5 m/s, and IP54/IP65 protection, with 16 TUV-certified safety features supporting human-machine collaboration. Perception is built on 2D/3D vision depth fusion paired with high-sensitivity force sensing and control, and drag-and-drop teach programming keeps setup accessible without specialist skills. Scenario-specific software packages, multiple external interfaces, cloud-based robot data monitoring, and remote OTA upgrades round out the platform. The extra capacity makes it well suited to heavier picking, welding, loading and unloading, assembly, screw fastening, polishing and grinding, quality inspection, and gluing and oiling duties in hazardous zones.
