SIASUN Collaborative Robot (GCR25-1800)

SIASUN markets the model as part of a larger GCR cobot lineup, highlighting collaborative safety features, ease of use, and application-focused software packages.

Collaborative robots are typically designed to operate in closer proximity to people than conventional industrial robots, using safety functions such as collision detection and force/power limiting. For organizations seeking flexible automation—especially in mixed human-robot workspaces—cobots like the GCR25-1800 can be deployed for repeatable tasks while remaining adaptable to changing production needs.

Design and Features

Mechanical design and reach

The GCR25-1800 uses a 6-degree-of-freedom articulated arm configuration intended to provide dexterity for multi-angle approach paths and varied end-effector orientations. The model name reflects its headline specifications: 25 kg maximum payload and 1800 mm reach.

Collaborative safety and functional safety positioning

SIASUN emphasizes the GCR series’ safety stack, including collision detection and force/power detection, and references functional safety certification by TÜV SÜD as well as IEC 61508 certification in its product materials for the series.
In practice, collaborative deployments still require a formal risk assessment, appropriate tool design, and application-specific safety configuration—particularly for higher-payload cobots where the energy at the tool can be significant.

Software ecosystem and application packages

SIASUN promotes “multiple scenario” software packages (e.g., palletizing and welding) and support for common external interfaces (including DI/DO and analog I/O) as part of the GCR platform.
In palletizing-focused deployments, SIASUN describes packaged solutions that combine the cobot, a palletizing software suite, and workflow components intended to simplify commissioning.

Environmental protection (IP rating)

For industrial environments where dust or water exposure may be a factor, SIASUN lists IP54/IP65 protection classes (configuration-dependent) for the GCR25-1800.

Technology and Specifications

Key published specifications

According to SIASUN’s product page for the model, the GCR25-1800 has the following parameters:

• Max payload: 25 kg

• Reach: 1800 mm

• Degrees of freedom: 6

• Repeatability: ±0.05 mm

• Max TCP speed: 2.5 m/s

• Max straight-line speed: 1.5 m/s

• IP class: IP54 / IP65

SIASUN also describes palletizing solution packages that reference the same core performance profile (25 kg payload, 1800 mm working radius) and include deployment-oriented software tooling.

Implications of payload and reach for real deployments

In collaborative robotics, payload and reach influence more than “how heavy” and “how far.” A 25 kg-class cobot can support:

• larger grippers (vacuum arrays, multi-finger clamps, bag grippers),

• higher inertia tooling (within permissible limits),

• and multi-case pick patterns in end-of-line operations.

However, high-payload cobots often require careful cycle-time planning, appropriate mounting (floor, pedestal, or frame), and attention to workspace safety because the forces involved can exceed what is typically acceptable for unrestricted human contact.

Applications and Use Cases

Palletizing and end-of-line logistics

SIASUN positions the GCR25-1800 for palletizing process package solutions, describing packaged workflows and tooling support intended to streamline deployment in logistics-style tasks.
Typical cobot palletizing scenarios include:

• carton/case palletizing for food, beverage, and consumer goods,

• bag palletizing (with appropriate end-effectors),

• and depalletizing for inbound logistics or kitting.

Machine tending and material handling

With extended reach and a 25 kg payload rating, the robot can be applied to:

• loading/unloading CNC machines,

• moving bins or trays,

• and transferring workpieces between stations.

Assembly, inspection, and process support

SIASUN’s GCR25-1800 page lists application areas including assembly, quality inspection, painting, and polishing as representative domains.
In these contexts, the cobot’s suitability is typically determined by tool selection (e.g., cameras, force-controlled sanding heads) and the required process tolerances.

Advantages / Benefits

High payload cobot category with long reach

The primary differentiator of the GCR25-1800 is its placement in a higher payload class while maintaining collaborative positioning—useful for end-of-line operations where lighter cobots may be tool-limited or reach-limited.

Deployment-oriented software and interfaces

SIASUN highlights scenario software packages (notably palletizing) and broad interface support, which can reduce integration effort for standard factory I/O and common automation peripherals.

Environmental robustness options

The listed IP54/IP65 protection options (depending on configuration) suggest suitability for a wider range of factory environments than typical office-grade automation hardware.

FAQ Section 

What is the SIASUN GCR25-1800?

The SIASUN GCR25-1800 is a 6-axis collaborative robot rated for 25 kg payload with 1800 mm reach, intended for industrial tasks such as palletizing, machine tending, and material handling.

How does the GCR25-1800 work?

Like other articulated cobots, it uses six motorized joints to position a tool (end-effector) in 3D space. SIASUN describes the platform as supporting collaborative safety functions (e.g., collision and force/power detection) and application software packages to simplify tasks like palletizing.

Why is the GCR25-1800 important for automation?

It combines higher payload capacity and long reach within a collaborative product line, which can help automate end-of-line and logistics-style workflows (e.g., palletizing) that lighter cobots may not handle efficiently.

What are the key specifications of the GCR25-1800?

SIASUN lists: 25 kg payload, 1800 mm reach, ±0.05 mm repeatability, 2.5 m/s max TCP speed, and IP54/IP65 (depending on configuration).

What are the benefits of the GCR25-1800?

Common benefits include higher payload (25 kg) for bulk handling, long reach (1800 mm) for wide work envelopes, and access to application packages (such as palletizing) plus broad I/O support for factory integration.

Summary

The SIASUN GCR25-1800 is a 25 kg, 1800 mm reach, 6-axis collaborative robot positioned for industrial automation tasks—especially palletizing and material handling—that require more payload and reach than typical small cobots. With published parameters such as ±0.05 mm repeatability, up to 2.5 m/s TCP speed, and IP54/IP65 options, it fits into modern flexible automation strategies where collaborative operation, deployment speed, and application-ready software packages are key considerations.
