SIASUN Modular Truss Robot (M Series)

Walk through most machining halls and the floor is crowded: machine tools, conveyors, pallets, people and the walkways between them. The space overhead, by contrast, is usually empty. The SIASUN Modular Truss Robot (M Series) puts that unused height to work, carrying parts on beams and columns above the production line rather than competing with it for floor space. It achieves this not as a single fixed machine but as a kit of standardised modules that can be arranged to suit the cell.

Robots Europa, based in Dublin, sells and supplies the SIASUN Modular Truss Robot (M Series) to customers across the European Union and the DACH region. Robots Europa prepares each quotation for the specific sub-series and configuration a project needs, and arranges delivery and after-sales support for installations within its market.

Background

SIASUN and the M Series family

SIASUN developed the M Series as a standard product in response to market demand, and the family comprises six sub-series, each suited to different applications. Three of them are covered on this page: the MGI, the MGH and the MGA. Beyond the standard catalogue, SIASUN also offers to customise complete industry solutions built on the M Series, so the family serves as the foundation of a project rather than its fixed limit. Further SIASUN equipment, from collaborative arms to mobile robots, is listed in the SIASUN range.

Modular units and the rectangular guide rail

Every truss robot in the series is assembled from standardised modular units. SIASUN describes these units as flexible in combination, easy to install and highly adaptable, and because the modules are shared across the family, the products offer good interchangeability and versatility when parts are installed or replaced. On the horizontal axes, X and Y, all sub-series use a rectangular guide rail designed by SIASUN, running on driving roller bearings to permit ultra-high-speed movement. The X-axis stroke can be extended indefinitely to meet the user's requirements, which is why the same concept can serve a single machine or a long line of them. SIASUN also maintains what it calls a “parts supermarket”, from which customers can obtain the modules they require at any time.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

The manufacturer has not published the repeatability, positioning accuracy, weight, dimensions, power supply, control system model, acceleration, stroke limits per axis, IP rating, operating temperature or scope of delivery, nor the names of the remaining three sub-series; all of these are confirmed at quotation.

How do the MGI, MGH and MGA differ?

The three named sub-series divide along two lines: the axes they move on and the loads they carry. The MGI is the most direct arrangement, travelling along an X-axis with a single Z-axis and handling standard loads from 1 to 1000 kg at speeds of up to 240 m/min. It suits work where parts need to be lifted and moved along one line, for instance from a conveyor into a row of machines.

The MGH shares the MGI's load range and maximum speed but adds a second vertical axis: it travels along the X-axis with a double Z-axis. Two vertical axes on one carriage allow one to pick a finished part while the other holds a blank, a typical approach for shortening exchange time at a machine. The MGH can also take external A- and C-axes for rotation, and its control system can be selected to match the customer's existing practice. Its beams and columns are clamped rather than bolted, which SIASUN describes as an upgrade that adapts flexibly to the spacing between machines already on site.

The MGA is the heavy, full-Cartesian member of the family. It moves along X, Y and Z, carries standard loads from 1 to 5000 kg, and its Y-axis can span up to 12m while the X-axis stroke can be extended indefinitely. SIASUN describes the MGA as one of the most widely used and efficient industrial robots in machining.

What does the modular design mean in practice?

For a production engineer, modularity is chiefly about change. Lines are re-laid, machines are added and part families evolve; a gantry welded together for one layout becomes a constraint when that layout moves. Because the M Series is built from standardised units, beams, columns and axes can be recombined rather than discarded, and the indefinitely extendable X-axis allows a system to grow with the line it serves.

Modularity also matters for maintenance. Shared modules across the family mean that a replacement part is a catalogue item rather than a one-off fabrication, and SIASUN's “parts supermarket” is intended to supply the required modules at any time. For a plant in Europe weighing an imported automation system, the question of how quickly a worn component can be replaced is often as important as the headline specification, and Robots Europa can clarify spare-parts arrangements as part of the quotation.

Who is the SIASUN Modular Truss Robot (M Series) for?

The series is aimed first at manufacturers running machine tools, where automated loading and unloading allows spindles to keep turning without an operator at every door. Plants with a single line of machines and moderate part weights will usually find the MGI or MGH a natural fit, the MGH in particular where fast part exchange or rotation of the workpiece is required.

Operations handling heavy castings, forgings or large components, or needing to cover a wide area rather than a single line, should look at the MGA, with its loads of up to 5000 kg and a Y-axis span of up to 12m. System integrators building complete cells form another group: the open choice of control system on the MGH and SIASUN's offer to customise complete industry solutions give integrators room to design around the robot rather than around its limitations.

Where a project calls for floor-based mobility or articulated manipulation rather than overhead Cartesian handling, other machines in the Special Robots category may be the better starting point.

What is the SIASUN Modular Truss Robot (M Series) used for?

1. Machine tending: loading blanks into and removing finished parts from lathes, machining centres and grinders.
2. Multi-machine linking: carrying parts between successive machining operations along an extended X-axis.
3. Heavy-part handling: moving large workpieces with the MGA where manual lifting is impractical or unsafe.
4. Fast part exchange: using the MGH's double Z-axis to swap a finished part for a blank in one visit.
5. Area coverage: serving pallets, buffers and stations spread across a wide footprint with a full X-Y-Z gantry.
6. Custom production cells: forming the handling backbone of a complete industry solution tailored by SIASUN.

Pricing and Availability

Because every M Series installation is configured around its sub-series, axes, stroke and control system, Robots Europa quotes each project individually rather than publishing a list price. Delivery, customs and support are arranged together with the quotation. To begin, describe your parts, machines and layout, and request your quotation through the enquiry form available on this page.

Frequently Asked Questions

How many sub-series does the M Series include?

SIASUN states that the M Series comprises six sub-series. The MGI, MGH and MGA are the three covered on this page.

What loads can the M Series handle?

The standard product covers loads from 1 to 5000 kg. The MGI and MGH each handle 1 to 1000 kg, while the MGA handles 1 to 5000 kg.

How fast does the robot move?

SIASUN gives a maximum speed of 240m/min for the standard product, and 240 m/min for both the MGI and the MGH.

Can the X-axis be made longer?

Yes. The X-axis stroke can be extended indefinitely to meet the user's requirements, which allows the system to serve a long line of machines.

Can extra axes be added?

Additional axes can be added to the standard product, and the MGH can be fitted with external A- and C-axes.

How are the MGH's beams and columns connected?

On the MGH, the connection between beams and columns has been upgraded from bolting to clamping. This lets the structure adapt flexibly to the distance between machines already installed on site.

Where can I buy the SIASUN Modular Truss Robot (M Series) and what does it cost?

Robots Europa supplies the M Series across the EU and the DACH region. The cost depends on the sub-series and configuration, so Robots Europa provides a tailored quotation on request.

Summary

The SIASUN Modular Truss Robot (M Series) answers a simple observation: on a busy shop floor, the most available space is overhead. By building its truss robots from standardised modules running on SIASUN's own rectangular guide rail, the series turns that space into a handling route which can be extended, recombined and repaired as the line beneath it changes. The MGI and MGH serve single lines with loads of up to 1000 kg, the MGH adding a double Z-axis and clamped connections, while the MGA spans up to 12m and lifts up to 5000 kg.
