SIASUN MGA Truss Robot (MGA Truss Robot)

A machining line rarely stands still, and the machine tools are often the last thing anyone wants to move. The SIASUN MGA Truss Robot (MGA Truss Robot) works above them: a modular gantry that carries work across the cell on three axes while the floor stays free for operators and machines.

Background

SIASUN and the truss robot lineage

SIASUN was founded in 2000 and is based in Shenyang, China. Over the years it has built a range of industrial and special-purpose robots. The truss robot is one of its standard products for machining, developed according to market demand rather than as a one-off build for a single customer.

That lineage shows in the way the family is organized. The modular truss robot M series is a standard product with a total of six sub-series, each suited to different applications. The MGA is one version of this family, next to the MGH and MGI, and this page keeps to the MGA.

For buyers across the Caribbean, where a workshop may start with one machine tool and add more later, a standard family with interchangeable modules is a practical starting point. You can read about related equipment in the Special Robots category.

Positioning and key technology

SIASUN describes the MGA truss robot as one of the most widely used and efficient industrial robots in the field of machining. It is a standardized modular product that is flexible in combination, easy to install and highly adaptable.

Three design choices carry most of the weight. First, the X-axis of all series uses rectangular guide rails designed by SIASUN, with driving roller bearings, for ultra-high-speed movement. Second, every part with a fixed function is built as a module, which allows quick installation and easy maintenance. Third, the connection of beams and columns has been upgraded from a bolting connection to fixing by clamping, so the robot adapts flexibly to the distance between the equipment already standing on a user's site.

What makes the MGA different from an articulated arm on the floor?

An articulated arm is fixed at a base and reaches outward in an arc. A truss robot moves along rails above the work area and covers a rectangular space. That suits a machining line, where lathes and machining centers sit in a row and parts travel from one to the next.

The MGA adds to this the freedom to size the cell. The X-axis stroke can be extended infinitely to meet user requirements, and the Y-axis reaches a maximum span of 12m. The standard load range runs from 1 to 5000 kg, so the same product family covers light parts and very heavy workpieces.

Speed is the second difference. The X-axis subassembly, supported by rectangular guide rails and roller modules, has high rigidity and high environmental adaptability, and it can run at high speed even with long strokes. Long travel usually forces a compromise between reach and speed; this design avoids it. For the wider M series, the maximum speed is 240m/min along the X-axis, Y-axis and Z-axis.

How does the modular design help after installation?

Each part with a fixed function is a module. Because of this, all products have good interchangeability and versatility, which is convenient for installation and replacement. If a module needs attention, the work is a swap rather than a rebuild.

SIASUN also runs what it calls a parts supermarket, which can supply the modules customers require at any time. Customization goes further: additional external axes (A-axis and C-axis) can be added, and the control system can be selected to match how your team likes to work. The clamped beam and column connection means a layout can follow the distances between your existing machines instead of the other way round.

Who is the MGA Truss Robot for?

Machine shops and component manufacturers that load and unload machine tools will find the most direct fit. A standard modular product lets them start from a proven configuration and then size it to their floor.

Integrators will value the combination of standard modules and the option to add external axes and choose the control system. Plant engineers planning for growth will see the benefit of an extendable X-axis stroke and of parts that can be replaced as modules.

If your task is moving loads across a yard or a warehouse rather than serving machines from above, a mobile platform suits better. In that case, look at the SIASUN 3T Heavy-Duty Mobile Robot or the SIASUN 10,000 Kg Heavy-Duty Mobile Robot.

What is the MGA Truss Robot used for?

1. Machine tool loading and unloading. Moves workpieces between the stock position and the machine along the X, Y and Z axes.
2. Transfer between machines. Carries parts from one machining step to the next along a row of machine tools.
3. Heavy workpiece handling. The standard load range reaches 5000 kg for large parts.
4. Long-span cells. A Y-axis span of up to 12m and an extendable X-axis stroke cover wide working areas.
5. Multi-axis tasks. External A-axis and C-axis can be added where the part must be turned or tilted.
6. Line expansion. Modules can be added or replaced as the line changes.

Frequently Asked Questions

What load can the MGA Truss Robot handle?

The standard product load ranges from 1 to 5000 kg. The right figure for your case is set in the quotation.

How large a work area can it cover?

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

Which axes does it move on?

It achieves high-speed movement on the X-axis, Y-axis and Z-axis. Additional external axes, the A-axis and the C-axis, can be added.

Can the control system be chosen?

Yes. The appropriate control system can be selected based on the customer's usage habits.

Is it easy to maintain?

Each part with a fixed function is a module, which allows quick installation and easy maintenance. The parts supermarket can supply the modules customers require at any time.

Can it fit around the machines I already have?

Yes. The connection of beams and columns is fixed by clamping, which adapts flexibly to the distance between the equipment on your site.

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

You can request it through this page, by quotation. The cost depends on the configuration, so it is given in the quotation and not as a fixed figure here.

Summary

The machine tools stay where they are, and the MGA works above them. Its rectangular guide rails, clamped beam and column connection and fully modular construction make a standard product that can still be fitted to your floor. A load range of 1 to 5000 kg, a Y-axis span of up to 12m and an extendable X-axis stroke give it room to grow with your line. To size one for your workshop, this page is the starting point.
