SIASUN Heavy Payload Mobile Robot

A crane can lift a die, but it cannot walk it to the next press, and a drag chain pulls a truck chassis only along the path it was laid for. The SIASUN Heavy Payload Mobile Robot takes a different approach: the load rides on a vehicle that finds its own way through the facility. SIASUN builds these robots to carry oversized and ultra-heavy items automatically, from the factory floor to the container yard.

Background

SIASUN and its heavy-load lineage

SIASUN is a Chinese robotics maker whose heavy payload mobile robots have a long record in industrial service. From 2010 to 2015, SIASUN supplied over 50 heavy payload mobile robots of various types to high-speed train maintenance bases nationwide for frame repair, which made it one of China's pioneers in this field. That early work in rail maintenance was the foundation for what followed.

In 2018, SIASUN introduced heavy truck assembly line mobile robots. Since 2020, its heavy payload mobile robots have gone global, supplying large batches to the world's largest transshipment hub ports. The path runs from workshop frames to assembly lines to harbor terminals, and each step called for a heavier or harsher duty than the one before.

Positioning and key technology

The hallmark of this line is its carrying capacity and technical sophistication, with payloads ranging from several tons to hundreds of tons. The robots are not a single fixed design. The mobile robot bodies and auxiliary mechanisms can be customized based on client requirements, so the vehicle fits the user's manufacturing process rather than the other way around.

Navigation is another area of strength. SIASUN's heavy payload mobile robots employ natural contour navigation, magnetic guidance, inertial navigation, laser guidance, visual navigation and base station navigation. Many of the navigation sensors used in these systems are proprietary SIASUN developments. That means the choice of method can follow the site: an indoor assembly hall and an open port apron do not ask the same thing of a robot.

The robots serve construction machinery, automotive and parts manufacturing, metal processing, aircraft production, port logistics and energy storage. SIASUN describes them as driving intelligent, high-end upgrades across these industries.

What makes a heavy payload mobile robot different from a crane or a drag chain?

A crane serves the area under its rail, and a drag chain serves the route it was built along. Both are fixed infrastructure, and changing the layout of the plant means rebuilding them. A mobile robot carries the load itself and moves by navigation, so the route is a matter of configuration rather than construction. In heavy truck assembly, SIASUN uses dual-vehicle linkage technology so that its robots replace traditional drag chains, assisting in the assembly of truck chassis and complete vehicles at a payload capacity of 10-20 tons.

The second difference is how the robot is fitted to the job. In stamping workshops, robots equipped with piggyback and chain conveyor mechanisms transfer dies and metal sheets between workstations and presses, and some of them offer a 60-ton carrying capacity for die transportation. In ports, the robots automate the transfer of shipping containers, each designed to handle a payload of 65 tons. The body and the auxiliary mechanism change from one application to the next, while the navigation and safety approach stays within one family.

How is safety handled on a vehicle this heavy?

SIASUN's designs adhere to ISO3691-4 standards, with safety levels engineered to PLD&E classifications. The robots are equipped with emergency stops, contact and non-contact protective devices (safety certified), operational indicator lights, audio alarms, brakes, stall protection and actuator safeguards. For people working near a load of tens of tons, these layers matter as much as the payload figure.

Who is the SIASUN Heavy Payload Mobile Robot for?

Automotive and parts manufacturers are the most obvious buyers: press shops that move dies between presses, and truck makers that want to retire drag chains from the final assembly line. Port and terminal operators form a second group, since the container version is built around a 65-ton payload. Energy storage producers, who need low-profile vehicles that tolerate outdoor conditions, form a third. Builders of construction machinery, metal processors and aircraft producers round out the picture.

Buyers who already know their load and want a specific high-capacity model can look at the SIASUN 80T Heavy-Duty Mobile Robot. Those focused on vehicle assembly may also compare the SIASUN Four-Lift Automotive Assembly Mobile Robot. For the wider range, see the SIASUN category.

What is the SIASUN Heavy Payload Mobile Robot used for?

1. Die transport in stamping workshops. Piggyback and chain conveyor mechanisms move dies and metal sheets between workstations and presses.
2. Heavy truck assembly. Dual-vehicle linkage replaces drag chains for chassis and complete vehicle assembly.
3. Port container transfer. Each robot handles a 65-ton payload in shipping container transfer.
4. Energy storage handling. Waterproof, ultra-low-profile versions carry heavy loads and operate outdoors.
5. Outdoor heavy transport. Outdoor models are engineered to withstand rain, snow and dust.
6. Rail maintenance and aircraft production. The line has served frame repair at high-speed train bases and supports aircraft production.

Yes. The outdoor heavy payload mobile robots are engineered to withstand rain, snow and dust, and the energy storage version has a waterproof design and outdoor operability.

How does the robot navigate?

It can use natural contour, magnetic, inertial, laser, visual or base station navigation. Many of the navigation sensors are proprietary SIASUN developments.

Which safety standard applies?

The designs adhere to ISO3691-4, with safety levels engineered to PLD&E classifications. Protective devices include emergency stops and safety certified contact and non-contact devices.

Can the robot be adapted to our process?

Yes. The robot bodies and auxiliary mechanisms can be customized based on client requirements.

Which industries use these robots?

They serve construction machinery, automotive and parts manufacturing, metal processing, aircraft production, port logistics and energy storage.

Summary

The heaviest objects in a plant no longer have to wait for a crane or follow a fixed chain. The SIASUN Heavy Payload Mobile Robot carries them on its own, from several tons to hundreds of tons, with navigation that suits the site and safety designed to ISO3691-4. Stamping shops, truck lines, ports and energy storage plants each get a version fitted to the job. To discuss your load and your site, this page is the starting point.
