SIASUN MGA Truss Robot (MGA Truss Robot)

A bespoke gantry is usually engineered once, for a single cell, and from that day on every change to the line becomes a small engineering project of its own. The SIASUN MGA Truss Robot takes the opposite route. It is assembled from standardised modules, each with a fixed function, so that the system can be configured for the cell in front of it and reconfigured when that cell changes. In machining, where a truss robot carries workpieces overhead between machine tools, the difference between a one-off structure and a set of interchangeable parts affects everything from installation day to the spare-parts shelf.

Robots Middle East supplies the SIASUN MGA Truss Robot to manufacturers and system integrators across the Middle East. We prepare each quotation around your cell layout, workpiece loads and preferred control environment. We also coordinate delivery to your site and remain your point of contact for technical support and module supply once the system is in service.

Background

SIASUN: a Shenyang manufacturer since 2000

SIASUN was founded in 2000 and is based in Shenyang, China. Its catalogue spans several families of industrial equipment, from heavy-duty mobile robots to the overhead handling systems listed among its Special Robots. The truss robots belong to the part of that catalogue concerned with moving material through production: they are fixed installations that sit above the working area and carry parts between stations along defined linear axes.

A standard product built from a modular family

SIASUN developed its modular truss robot range, the M series, as a standard product in response to market demand. The series comprises six sub-series in total, each suited to different applications, and the M series is specified for a maximum speed of 240m/min along the X-axis, Y-axis and Z-axis, with additional axes available. The range includes the MGA, MGH and MGI versions. The MGA is one of the most widely used and efficient industrial robots in the field of machining. It is a standardised modular product that is flexible in combination, easy to install and highly adaptable. The central idea is that each part with a fixed function is treated as a module. As a result, the products share good interchangeability and versatility, and installation and replacement become a matter of fitting known components rather than fabricating new ones.

Technical Specifications

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

The manufacturer has not published the dimensions, weight, positioning repeatability, power requirements, motor and drive type, control system model, IP rating, maximum acceleration, per-axis stroke figures, operating temperature range or the contents of the delivery; Robots Middle East confirms these at quotation.

What makes the MGA truss robot different from a bespoke gantry?

A custom-built gantry can be tailored precisely to one layout, but that precision has a cost later on: altering the span, adding a station or replacing a worn component often means returning to drawings and fabrication. The MGA approaches the problem from the other direction. Its structure is defined by standard modules, and all products share good interchangeability and versatility. A plant therefore works with a known set of components whose functions are fixed, rather than with a structure that exists only once.

The way beams and columns are joined reinforces this. SIASUN has upgraded the connection from bolting to clamping, so the structure adapts flexibly to the distance between the user's existing on-site equipment. In practice, the robot is fitted to the machines already on the floor rather than the other way round. The X-axis stroke can be extended infinitely to meet user requirements, and the Y-axis spans up to 12m, giving considerable freedom in how a cell or a line of machines is covered from above.

Flexibility of form does not come at the expense of performance. The X-axis subassembly runs on rectangular guide rails designed by SIASUN, supported by roller modules. This arrangement gives high rigidity and high environmental adaptability, and maintains high-speed operation even over long strokes. That last point matters most where a single gantry serves a row of machine tools.

How does the modular design affect installation and maintenance?

Because each functional part is a module, the MGA enables quick installation and easy maintenance. For a production manager, this changes the planning of downtime: a component that needs replacing is a standard module rather than a custom piece, and SIASUN's "parts supermarket" can supply the modules customers require at any time. The same logic applies to expansion. Where a process later needs rotation or orientation of the part, additional external axes, the A-axis and C-axis, can be added. The control system can also be chosen to match the habits of the plant's own engineers, which shortens the learning curve on the shop floor.

Who is the SIASUN MGA Truss Robot for?

The MGA is aimed first at machining operations: plants running lathes, machining centres and similar machine tools that need parts loaded, unloaded and transferred without tying up operators. Its standard load range of 1 to 5000 kg means it can be considered both for light components and for heavy workpieces such as castings or large shafts.

It also suits system integrators who build automated cells for several clients, because a standardised, modular product simplifies design, commissioning and later service. Plants that expect their layout to change, whether by adding machines, extending a line or introducing new part families, benefit from the clamped connections and extendable X-axis. Maintenance teams that value a predictable spares strategy will also appreciate the module-based supply.

SIASUN also offers the MGH and MGI versions. Robots Middle East will advise on which of the three versions best fits your application when preparing the quotation.

What is the SIASUN MGA Truss Robot used for?

1. Machine tending: loading raw parts into CNC machine tools and removing finished parts from them.
2. Inter-machine transfer: carrying workpieces overhead between successive machining stations along a line.
3. Heavy-part handling: moving large castings, forgings or shafts that are impractical to handle manually.
4. Stacking and palletising: placing finished components into trays, racks or pallets at the end of a cell.
5. Line linking: connecting separate machines into a continuous automated flow without occupying floor space.
6. Part reorientation: turning or rotating workpieces between operations when external A-axis or C-axis modules are added.

Pricing and Availability

Each MGA installation is configured for its cell, so Robots Middle East quotes it on the basis of your layout, loads, required axes and preferred control system. Please share your machine arrangement and workpiece details, and we will return a quotation matched to your application. Delivery, customs and support are arranged with the quotation. To begin, use the quotation request available on this page.

Frequently Asked Questions

What load can the SIASUN MGA Truss Robot handle?

The standard product covers a load range of 1 to 5000 kg. We match the configuration to your workpiece when preparing your quotation.

How long can the X-axis be?

The X-axis stroke can be extended infinitely to meet user requirements. We define the length your layout needs when preparing your quotation.

What is the maximum Y-axis span?

The maximum span of the Y-axis is 12m.

Can additional axes be added?

Yes. Additional external axes, namely an A-axis and a C-axis, can be added to the three linear axes.

Can I choose the control system?

The control system can be selected to suit your engineers' usage habits. Robots Middle East will help you select the one that fits your plant.

How are spare parts supplied?

Because the robot is built from standard modules, SIASUN's "parts supermarket" can supply the modules customers require at any time. Robots Middle East coordinates module supply for customers in the region.

Where can I buy the SIASUN MGA Truss Robot and what does it cost?

You can buy the SIASUN MGA Truss Robot from Robots Middle East, which supplies it across the Middle East. The cost depends on the configuration, so we provide it in a quotation prepared for your application.

Summary

The SIASUN MGA Truss Robot replaces the one-off gantry with a set of standard modules: clamped beam and column connections that fit existing equipment, an X-axis that can be extended to suit the line, a Y-axis span of up to 12m and a standard load range of 1 to 5000 kg. Rigid rectangular guide rails keep the X-axis fast over long strokes, optional A-axis and C-axis modules extend what the cell can do, and a ready supply of modules keeps maintenance predictable.
