SIASUN Modular Truss Robot (M Series) (Modular Truss Robot (M Series))

Most factories run out of floor space long before they run out of height. The air above machine tools, conveyors and press lines is usually empty, and that is precisely where the SIASUN Modular Truss Robot (M Series) does its work: a Cartesian handling system carried on beams and columns, moving parts in straight lines between stations while the floor beneath stays clear for operators, forklifts and equipment. Rather than a single fixed machine, it is a family built from standardised modular units, so the same programme can be laid out as a compact two-axis loader over one machine or as a wide gantry spanning an entire group of cells.

Robots Europa, based in Dublin, supplies the SIASUN Modular Truss Robot (M Series) to customers throughout the European Union and the DACH region. Robots Europa prepares the quotation for the configuration your application requires, coordinates delivery to your site and remains your point of contact for technical questions and support once the system is in service.

Background

SIASUN and the M series programme

SIASUN developed the M series as a standard product in response to market demand, and organised it into six sub-series intended for different applications. Three of these versions are detailed here: MGI, MGH and MGA. Each answers a different handling problem, from straightforward two-axis transfer to heavy three-axis gantry work, yet all of them draw on the same set of building blocks. The M series also serves as the basis for complete and advanced industry solutions customised to the user, which means the robot is offered not only as a set of axes but as the foundation of an engineered handling cell.

Within the wider SIASUN range, which also covers articulated industrial robot arms, collaborative robots and mobile robots, the truss robot fills a distinct role. Where an articulated arm reaches around a fixed base, a truss robot travels along its own structure, covering long, rectangular working areas with simple, predictable motion paths.

Standardised modules and the rectangular guide rail

Every truss robot in the M series is composed of standardised modular units. These units are flexible in combination, easy to install and highly adaptable, and because the design is modular, the products offer good interchangeability and versatility, which simplifies both installation and later replacement of parts. SIASUN supports this with a “parts supermarket” that can supply the modules customers require at any time.

The key mechanical element is the guide rail. On all series, the X-axis and Y-axis, the horizontal axes, use a rectangular guide rail designed by SIASUN. Combined with driving roller bearings, this rail enables ultra-high-speed movement, and the X-axis stroke can be extended infinitely to meet user requirements. In practice this means the length of the system is set by the layout of your production line rather than by a fixed catalogue dimension.

What is the difference between the MGI, MGH and MGA versions?

The three named versions share the modular architecture but differ in how many axes they move and how much they carry. The MGI is the simplest arrangement: a load range of 1 to 1000 kg with high-speed movement along the X-axis and Z-axis, at a maximum speed of 240 m/min. It suits work where a part travels along a line and is lifted or lowered at fixed stations.

The MGH keeps the same 1 to 1000 kg load range and 240 m/min maximum speed, but moves along the X-axis and a double Z-axis. Two vertical axes on one horizontal travel allow two handling actions to share a single beam. The MGH can also be extended with external A-axis and C-axis rotary axes, and its control system can be chosen to match the customer’s usage habits, which matters when a plant has standardised on a particular control environment. Its beams and columns are now fixed by clamping rather than bolting, an upgrade that lets the structure adapt flexibly to the spacing of equipment already on site.

The MGA is the full three-axis gantry. Its load range extends from 1 to 5000 kg with movement along the X-axis, Y-axis and Z-axis, its X-axis stroke can be extended infinitely, and the maximum span of its Y-axis is 12m. This is the version for heavy parts and wide working areas covering several machines side by side.

Why does a modular truss design matter for your production line?

A conventional gantry is often engineered once for one layout, and changing that layout later means new steelwork. Because the M series is assembled from standardised, interchangeable units, a system can be planned around the line as it exists today and adjusted as it evolves. The infinitely extendable X-axis stroke removes a common constraint on line length, and the availability of modules from SIASUN’s parts supermarket helps keep spare parts and future extensions straightforward. For maintenance teams, interchangeable modules mean fewer unique components to stock; for planners, the ability to add axes means a handling task can grow without replacing the robot.

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

The M series is aimed at manufacturers and system integrators who need to move parts between stations over long, straight paths, and who prefer to keep the floor free beneath the handling equipment. Typical buyers include machining shops automating the loading of machine tools, metalworking plants transferring blanks and finished parts, and integrators who build complete cells and want a handling platform they can configure for each project.

The choice of version follows the task. Where parts travel along a single line and are picked and placed at fixed points, the MGI covers the requirement with the fewest axes. Where two handling actions must share one beam, or where rotation of the part is needed, the MGH with its double Z-axis and optional A-axis and C-axis is the better fit. Where loads exceed what the MGI and MGH carry, or where the working area must be covered in both horizontal directions, the MGA, with its 1 to 5000 kg load range and Y-axis span of up to 12m, is the appropriate version. Buyers comparing gantry systems with other specialised SIASUN equipment can browse the Special Robots category.

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

1. Machine tending: loading and unloading lathes, machining centres and grinders from above the machine.
2. Line transfer: carrying workpieces between successive stations along a production line.
3. Heavy part handling: moving large castings, forgings or assemblies that are impractical to lift by hand.
4. Palletising and stacking: placing parts or packages into ordered layers within a defined area.
5. Press and sheet-metal lines: feeding blanks into and removing parts from forming equipment.
6. Assembly feeding: supplying components to assembly stations at a steady, repeatable rhythm.

How fast does the robot move?

The series reaches a maximum speed of 240m/min along the X-axis, Y-axis and Z-axis. The MGI and MGH each move at up to 240 m/min.

Is the length of the system limited?

The X-axis stroke can be extended infinitely to meet user requirements. On the MGA, the maximum span of the Y-axis is 12m.

Can further axes be added?

Yes. Additional axes can be added across the series, and the MGH can be fitted with external A-axis and C-axis rotary axes.

Which control system does the robot use?

For the MGH, the control system is selected based on the customer’s usage habits, so it can match the control environment your plant already works with.

Summary

The SIASUN Modular Truss Robot (M Series) puts the unused space above a production line to work. Built from standardised, interchangeable modules running on SIASUN’s rectangular guide rail, it scales from the two-axis MGI through the double Z-axis MGH to the heavy-duty MGA, with loads from 1 to 5000 kg across the series and an X-axis stroke that follows the length of the line rather than limiting it. Robots Europa configures, quotes, delivers and supports the system for customers in the EU and the DACH region.
