SIASUN Outdoor Trackless Guided Heavy Payload Mobile Robot (Harbour)

A container ship can be unloaded only as fast as the ground beneath the cranes can carry the boxes away. The SIASUN Outdoor Trackless Guided Heavy Payload Mobile Robot (Harbour) works in that gap. It is a driverless transporter that waits under the shore bridge, receives the container and carries it to the yard without rails, tracks or a person at the wheel.

The product is available through this page, by quotation.

Background

SIASUN and its port robots

SIASUN is a robotics manufacturer whose range covers mobile robots, logistics robots and industrial automation. Its heavy payload mobile robots have moved from the factory floor into the open air of the quayside. Since 2020 these robots have gone global, supplying large batches to the world's largest transshipment hub ports. The Harbour model has been exported overseas and stationed in world famous ports, where it has been put into use.

For a buyer in the Caribbean, where ports serve as transshipment points between continents, that track record is a useful reference. Terminals here face the same pressure as any hub: vessels wait for no one, and every minute at berth counts. Automating the horizontal transport between ship and yard is one of the most direct ways to keep that stage predictable.

Positioning and key technology

The Harbour robot is an outdoor, trackless, guided vehicle built for heavy loads. Trackless means that no rails or fixed guide paths have to be built into the terminal surface. Guided means that the vehicle finds its way by positioning systems instead of a driver. It uses inertial guidance, magnetic peg, RTK differential, UWB, laser contour, vision, 5G and GPS positioning, and so on. Several methods can be combined, so the robot does not depend on a single signal.

Two further technologies shape how the robot behaves in daily work. The first is a heavy-duty battery swap system, developed for batteries weighing up to 7 tonnes that can be swapped in 5 minutes. The second is a system-calculated, wedge-shaped lane change that lets the robot move between lanes with flexibility while keeping the operation efficient.

How does the Harbour robot handle different containers?

Terminals rarely see only one kind of box. The Harbour robot supports multiple types of cargo loading. In a single trip it can carry 2x20ft containers, 2x20ft tanks, a 40ft container or a 45ft container, each of these as its own loading case. A terminal that mixes twenty-foot and forty-foot traffic does not need a separate vehicle class for each format, which keeps fleet planning simpler.

The robot travels at up to 7m/s for 95 tonnes of heavy loads. That figure describes the speed and load together, so it should be read as one statement and not as two separate ratings.

Why does positioning accuracy matter at the quay?

The handover under a shore bridge is a precise moment. The shore bridge equipment grabs the container from the ship and transfers it to the top of the waiting robot below. If the vehicle stands in the wrong place, the crane has to wait or correct. Positioning accuracy can be controlled at ±5cm, which supports a repeatable handover at the crane.

Accuracy also matters on the way. The robot passes through multiple work areas, so it is equipped with an automatic stopping function to avoid collision. In addition, it changes lanes in a wedge shape according to the system calculation, which greatly improves the flexibility and passing ability of the operation and ensures its efficiency.

Who is the SIASUN Harbour robot for?

The primary buyer is a container terminal operator that wants unmanned horizontal transport between the shore bridge and the yard area. Port authorities and logistics groups modernizing a quay are the second group, particularly where mixed container sizes are handled and where the terminal cannot easily lay tracks into the surface.

System integrators who design automated terminals are a third group. The range of navigation methods lets them match positioning to the conditions of a site. Engineering contractors planning new quay extensions can also use the robot as the transport element of a wider automation plan.

If your need is lighter, such as moving pallets inside a warehouse, a port vehicle is not the right tool. Browse the Mobile Robots or Logistics Robots categories for models that suit indoor handling.

What is the SIASUN Harbour robot used for?

1. Shore bridge to yard transport: it receives containers from the shore bridge equipment and carries them to the yard area.
2. Mixed cargo handling: it carries 2x20ft containers, 2x20ft tanks, 40ft containers or 45ft containers in a single trip.
3. Unmanned cross-area operation: it moves through multiple work areas without a driver and stops automatically to avoid collision.
4. Flexible lane use: it changes lanes in a wedge shape according to the system calculation, improving its passing ability.
5. Continuous fleet operation: it takes a swapped battery in 5 minutes, so a vehicle returns to work quickly.
6. Precise container handover: it holds positioning accuracy at ±5cm at the crane.

Summary

The quay crane lifts the container, but the robot decides whether the next lift can happen on time. The SIASUN Harbour robot is a trackless, guided transporter with ±5cm positioning, up to 7m/s for 95 tonnes of heavy loads, four cargo loading cases and a battery swap that takes 5 minutes. It is backed by exports to world famous ports. If you are planning to automate the stretch between ship and yard, this page is the starting point.
