SIASUN 20T Heavy-Duty Mobile Robot (20T Heavy-Duty Mobile Robot)

Heavy industry has long moved its largest loads through the air. An overhead crane lifts an assembly, swings it across the hall and sets it down, and much of the floor beneath waits until it has done so. The SIASUN 20T Heavy-Duty Mobile Robot (20T Heavy-Duty Mobile Robot) takes the opposite approach. It drives beneath the load, raises it slightly clear of its supports and carries it along the floor, steering in any direction and turning on the spot. Where crane time is scarce and aisles are crowded, keeping a heavy load low and moving can change how a whole shift is planned.

Robots Middle East supplies the SIASUN 20T Heavy-Duty Mobile Robot to industrial customers across the Middle East, from port operators and shipyards to steel works and energy-storage manufacturers. Robots Middle East prepares each quotation around the customer's application, coordinates delivery to site and remains the point of contact for technical support once the robot is in service.

Background

SIASUN and its roots in automation

SIASUN is a Chinese robotics and automation company based in Shenyang, whose origins lie in robotics research within the Chinese Academy of Sciences. Its portfolio covers industrial robots, mobile robots and complete automated production and logistics systems, and it is known for large-scale factory automation rather than consumer products. The heavy-duty mobile robot range comes out of that background. It is intended for plants in which material flow is a production problem in its own right, not just a matter of warehouse handling.

A range built around payload

SIASUN offers its heavy-duty mobile robots as a family of versions, each defined by the load it is designed to carry. The versions named by the manufacturer are the 3T, 5T, 10T, 20T, 30T, 60T and 80T, and the series is described as covering 3–120 t capacity. All versions share the same design approach. An optimised wheel system balances load capacity and driving performance while protecting the floor. Omnidirectional movement with zero turning radius allows tight manoeuvres, and several navigation options allow precise positioning and path planning. The 20T sits in the middle of the range. It is suited to the large but not exceptional assemblies that make up much of the daily work in heavy manufacturing.

Technical Specifications

Specifications are given as published by the manufacturer and are confirmed against the datasheet at quotation. The manufacturer has not published the dimensions, weight, travel speed, battery capacity, battery type, charging time, IP rating, power supply voltage, operating temperature, package contents or software platform compatibility; Robots Middle East confirms these details at quotation.

How does the SIASUN 20T Heavy-Duty Mobile Robot differ from an overhead crane or a conventional AGV?

An overhead crane is fixed to the building. It serves the area beneath its runway and nothing beyond it, and while it is carrying one load it cannot carry another. The SIASUN 20T Heavy-Duty Mobile Robot is not tied to a runway. It can follow a route through the facility, pass from one hall to the next where the floor allows, and work alongside the crane instead of competing for it. Because it lifts from beneath with a stroke of 80-100 mm, the load stays close to the floor throughout the move rather than hanging overhead. That changes how the area around a transfer is organised and how many people are needed to supervise it.

A conventional automated guided vehicle usually steers like a car or forklift and needs room to turn. The 20T moves omnidirectionally with zero turning radius. It can travel sideways into a bay, rotate in place beside a fixture and approach a station from whichever direction the layout requires. Combined with positioning accuracy of ±10 mm, this lets the robot deliver an assembly directly to a workstation instead of to a set-down area from which it must be moved again. The optimised wheel system is designed to spread the demands of a heavy load in a way that protects the floor, which matters in plants where floor surfaces are costly to repair.

The robot is also built for fleet operation. It switches seamlessly between multi-robot coordination and single-robot operation. Several units can therefore share a very large or awkward load, or each can work independently on separate tasks, depending on what the shift requires.

Which navigation method suits a given facility?

The 20T supports three navigation methods: SLAM, magnetic guidance and colour-tape guidance. SLAM navigation builds a map of the surroundings and locates the robot within it. It needs no markings on the floor, which suits facilities whose layouts change from project to project, such as shipbuilding halls or aerospace assembly areas. Magnetic guidance follows markers set into or onto the floor. It suits fixed, repeated routes where the path is unlikely to change and where floor markings face heavy wear. Colour-tape guidance follows a visible line, which is quick to lay out and simple to adjust. It is often chosen for initial deployments or for areas where routes are revised from time to time.

Many sites combine methods. They might use fixed guidance on a busy main transport route and map-based navigation in the assembly areas it serves. Robots Middle East reviews the site layout, floor condition and process flow as part of the quotation, so that the navigation configuration matches how the plant actually works.

Who is the SIASUN 20T Heavy-Duty Mobile Robot for?

The 20T is intended for manufacturers and operators whose loads are routinely measured in tens of tonnes. Shipyards moving hull blocks and outfitting modules, aerospace plants transferring large structures between assembly stations, and automotive or construction machinery manufacturers handling frames, moulds and heavy subassemblies all fall within this group. Port and container logistics operators, energy-storage producers moving battery systems, and steel and metallurgy plants handling coils, rolls and process equipment are further natural users. The obstacle-crossing ability and stable travel for harsh processes are relevant to these environments, where floors are rarely perfect and conditions are demanding.

Not every heavy load calls for this particular version. Operations whose loads stay comfortably lighter may find the SIASUN 10,000 Kg Heavy-Duty Mobile Robot a better match. Plants that regularly move heavier assemblies should look at the SIASUN 30T Heavy-Duty Mobile Robot (30T Heavy-Duty Mobile Robot) or the SIASUN 60T Heavy-Duty Mobile Robot (60T Heavy-Duty Mobile Robot). The full family is presented under Heavy Duty Mobile Robots, and wider automation options can be found among our Factory Robots. Robots Middle East will advise which version best fits the load profile described in an enquiry.

Frequently Asked Questions

What payload does the SIASUN 20T Heavy-Duty Mobile Robot carry?

The 20T has a payload capacity of 20 t. For heavier or lighter loads, other versions in the SIASUN range may be more suitable.

How accurately does it position a load?

Positioning accuracy is ±10 mm. This allows assemblies to be delivered directly to workstations and fixtures.

How high does it lift the load?

The lifting height is 80-100 mm. This is enough to raise a load clear of its supports while keeping it close to the floor during transport.

Can several robots work together?

Yes. The robot switches seamlessly between multi-robot coordination and single-robot operation, so units can share a task or work independently.

Can it travel on ramps?

The gradeability is 3%. Routes with steeper slopes should be reviewed with Robots Middle East during the quotation process.

Does it require markings on the floor?

Not necessarily. SLAM navigation works without floor markings, while magnetic guidance and colour-tape guidance use markers or tape laid along the route.
