SIASUN MGH Truss Robot (MGH Truss Robot)

Every machining shop runs out of floor before it runs out of work. The SIASUN MGH Truss Robot answers that problem by moving the work overhead: a frame of beams and columns that carries parts between machines while the floor below stays free for people, carts and equipment. It is built from standard modules rather than drawn from scratch for each line, and that choice shapes almost everything about how it is bought, installed and maintained.

The product is available through this page, by quotation.

Background

SIASUN and the M series lineage

SIASUN was founded in 2000 and is based in Shenyang, China. The company develops industrial robots across several families, and the truss robot is one of its standard products for the machining field. You can see more of the maker's range in the SIASUN category, and the wider group of non-articulated and application-specific machines in Special Robots.

The MGH belongs to SIASUN's modular truss robot family, called the M series. SIASUN developed the M series as a standard product according to market demand, and the series has a total of six sub-series suited to different applications. The sources name three versions of the truss robot: the MGH Truss Robot, the MGI Truss Robot and the MGA Truss Robot. This page is about the MGH, and no figure from another version is attributed to it here.

SIASUN describes the MGH as one of the most widely used and efficient industrial robots in the field of machining. That is a statement about a product type, and it explains why the design leans so heavily on standardization: a machine that is used in many plants has to adapt to many layouts without a new design each time.

Modular design as the key technology

The central idea is simple. Each part with a fixed function is treated as a module, which enables quick installation and easy maintenance. Because of this modular design, all products in the family have good interchangeability and versatility, which makes installation and replacement more convenient.

SIASUN also keeps what it calls a "parts supermarket", which can supply the modules a customer needs at any time. For a plant that cannot afford long waits on a worn component, this matters as much as the motion performance itself.

Two mechanical details stand out. First, the X-axis of all series uses a rectangular guide rail designed by SIASUN, with driving roller bearings, which allows ultra-high-speed movement. The X-axis subassembly is supported by rectangular guide rails and roller modules, giving high rigidity and high environmental adaptability, and it can run at high speed even over long strokes. Second, the connection between beams and columns has been upgraded from a bolted connection to fixing by clamping, which lets the frame adapt flexibly to the distance between the user's on-site equipment.

What makes the MGH different from a one-off gantry?

A custom gantry is drawn, fabricated and commissioned for a single line. That can work well, but the cost shows later: when a part fails or a layout changes, there is no standard module to reach for, and every change turns into a small engineering project.

The MGH takes the opposite route. Because each fixed-function part is a module, installation is quick and maintenance is easy, and replacement parts are interchangeable across the family. The "parts supermarket" extends that idea to supply, since the modules a customer requires can be provided at any time.

The frame itself is also built for adjustment. The move from bolted to clamped connections between beams and columns means the structure can follow the spacing of the equipment already on site rather than forcing the equipment to follow the structure. And because the X-axis stroke can be extended infinitely to meet user requirements, the same design can serve a short cell or a long row of machines.

How fast and how heavy can the MGH go?

The standard product load ranges from 1 to 1000 kg, which covers everything from light workpieces to very heavy ones within one product family. High-speed movement is available along the X-axis and the double Z-axis, with a maximum speed of 240 m/min.

Speed over a long travel is where the X-axis design earns its keep. The rectangular guide rail designed by SIASUN, together with driving roller bearings, supports ultra-high-speed movement, and the rigidity of the rail and roller module assembly lets the axis keep that speed even over long strokes. Where a job needs more than straight-line travel, additional external axes, the A-axis and C-axis, can be added, and the control system can be chosen to suit how the customer's team already works.

If your project depends on cycle time or positioning accuracy, send us your requirements with your quotation request and we will take them into the proposal.

Who is the MGH Truss Robot for?

Machine shops and machining-line integrators are the natural buyers. If you tend several machine tools in a row, moving blanks in and finished parts out, an overhead truss keeps the floor clear and lets one set of axes serve the whole line.

Plants with mixed or changing production will value the modular approach. When a layout is likely to change, standard modules, clamped beam-to-column connections and an extendable X-axis reduce the work of adapting the system.

Maintenance managers are a third group. Interchangeable modules and a supply of spare modules mean fewer surprises when a component needs replacing. Buyers with very heavy parts, up to the top of the standard load range, and buyers with light parts can both start from the same product family.

SIASUN also lists the MGI and MGA truss robots as other versions. If your application differs from what the MGH is built for, ask us how these versions compare for your task. For a broader view of the range, browse Special Robots.

What is the MGH Truss Robot used for?

1. Machine tending. Loading blanks into machine tools and removing finished parts, line after line.
2. Moving parts between machines. Carrying workpieces along a row of machines on the X-axis, with the double Z-axis handling lifting and lowering.
3. Heavy workpiece handling. Standard loads across a range of 1 to 1000 kg suit both light and very heavy parts.
4. Long-stroke transfer. An X-axis stroke that can be extended infinitely serves long production lines.
5. Added-axis tasks. External A-axis and C-axis can be added where the workpiece must be oriented as well as moved.
6. Floor-space saving automation. The overhead frame keeps the floor free for people and equipment.

Delivery, customs and support are arranged with the quotation. Tell us the weight of your heaviest part, the length of the line and the control preferences of your team, and we will build the proposal around them.

Frequently Asked Questions

What load can the MGH Truss Robot carry?

The standard product load ranges from 1 to 1000 kg.

How fast does it move?

The maximum speed is 240 m/min, achieved along the X-axis and the double Z-axis.

Can the travel length be adapted to my plant?

Yes. The X-axis stroke can be extended infinitely to meet user requirements, and the clamped beam-and-column connection adapts to the distance between your on-site equipment.

Can more axes be added?

Additional external axes, namely the A-axis and C-axis, can be added. The control system can be selected based on the customer's usage habits.

How easy is it to maintain and replace parts?

Each part with a fixed function is a module, which enables quick installation and easy maintenance. SIASUN's "parts supermarket" can supply the modules customers require at any time.

Are other versions of the truss robot available?

SIASUN also names the MGI Truss Robot and the MGA Truss Robot. Tell us about your application and we will help you compare them with the MGH.

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

It is available through this page, by quotation. The cost depends on the load, stroke and axes you need, so we provide it with the quotation and not as a printed figure.

Summary

The MGH Truss Robot takes the work overhead and keeps the floor free. Its strength is that it is standard: modules that install quickly, interchange freely and can be resupplied at any time, on a frame that clamps to the layout you already have. The standard load range of 1 to 1000 kg, the 240 m/min maximum speed and an X-axis stroke that can be extended infinitely make it a flexible foundation for a machining line, and added A-axis and C-axis give room to grow. If you are planning that line, this page is the starting point.
