SIASUN 2000 Kg Under-ride Lift Mobile Robot (P-T2000D)

Two tonnes of material are on the move, yet nothing in the aisle stands taller than a chassis of 336mm. That is the proposition of the SIASUN 2000 Kg Under-ride Lift Mobile Robot (P-T2000D). It does not approach a load from the side with forks and a mast. It drives underneath the rack, cart or carrier, raises it and takes it to wherever the process needs it next. Where heavy loads move often between fixed points, this changes how floor space, traffic routes and safety zones can be planned. The robot sits beneath the load rather than in front of it.

Robots Europa, based in Dublin, supplies the P-T2000D to manufacturers, logistics operators and system integrators throughout the European Union and the DACH region. Our team prepares the quotation, arranges delivery to your site and remains your point of contact for support after commissioning. A single European partner therefore handles the project from the first enquiry to everyday operation.

Background

SIASUN and the under-ride family

The P-T2000D belongs to a family of SIASUN under-ride lift mobile robots. The family shares one concept and is offered in five versions: the P-T600D, P-T1000D, P-T1500D, P-T2000D and P-T3000D. Across the line, payload options range from 600 to 3,000 kg. An operator can therefore choose the class of robot that matches its loads, instead of adapting its loads to the robot. SIASUN also offers non-standard customisation to meet customer requirements across diverse scenarios. This matters for sites whose carriers, racks or docking stations do not follow a standard pattern. The whole family can be compared in our Under-ride Lift Mobile Robots category.

Every SIASUN under-ride solution is supported by the IMRS 2.0 platform. This is SIASUN's software layer for multi-robot dispatching, route optimisation, data analytics and digital twins, providing end-to-end control. The P-T2000D is therefore a fleet member from the outset, not a stand-alone vehicle. Its value grows with the number of robots and tasks it shares a floor with.

Lifting from beneath: the under-ride principle

Under-ride robots, sometimes called latent or jacking mobile robots, are a familiar class in modern intralogistics. The robot travels beneath a raised load carrier, positions itself under the centre of the load, lifts it clear of the floor and carries it away. Because the vehicle stays under its load, the combined footprint in the aisle is essentially the footprint of the carrier. That is a clear advantage over counterbalanced trucks, which need room ahead of and behind the load to manoeuvre.

On the P-T2000D, the under-ride design gives precise access to pick-up points, and the lifting action is smooth, stable and efficient. Multi-sensor data fusion lets the robot carry out tasks with high precision and dock seamlessly with its carrier. This combination is what makes heavy, repeatable transfers practical without a driver. The robot arrives where the carrier stands, engages it and lifts it in one controlled sequence.

Technical Specifications

Specifications are given as published by the manufacturer and are confirmed against the datasheet at quotation.

SIASUN has not published the robot's own weight, travel speed, battery capacity, battery type, charging method, IP rating, safety certifications, gradeability, obstacle sensors, drive type or wireless communication; Robots Europa confirms these with you at quotation.

How precisely does the P-T2000D navigate and dock?

The P-T2000D can run on two navigation arrangements: SLAM combined with QR codes, or QR codes alone. In practical terms, SLAM lets a robot build and use a map of its surroundings from what it senses. Floor-mounted QR codes give it fixed reference points to confirm its exact position. A site can therefore choose between a fully marker-based layout, typical of dense and highly structured storage zones, and a hybrid approach. The hybrid approach adds flexibility in open areas while keeping markers where exactness counts most.

Positioning accuracy is ± 10mm/±1°. For an under-ride robot, this figure decides whether it can reliably centre itself beneath a carrier and set it down again at a station, rack position or conveyor interface. SIASUN pairs this accuracy with multi-navigation fusion and smooth switching between navigation modes. The robot does not have to stop and reorient when it passes from a mapped zone into a marker-guided one. A layered safety system is part of the same design, intended to keep operation dependable in areas shared with people and other vehicles.

How does the P-T2000D work within a robot fleet?

A heavy-load robot earns its place by how many productive hours it delivers and how well it shares work with others. The P-T2000D has a rated operating time of 6–8 hours. SIASUN describes the platform's environmental adaptability in terms of extended endurance, high drivetrain efficiency, strong carrier compatibility and fleet-level dispatching. Strong carrier compatibility is especially relevant where a site handles several types of rack or cart and wants one robot type to serve them all.

Dispatching runs through IMRS 2.0. The platform assigns tasks across multiple robots, optimises their routes, analyses operating data and supports digital twins. A digital twin lets a planner model a layout or a change in throughput before committing floor space or hardware. Shift patterns and charging strategy are worth agreeing early in the project. Robots Europa sets these out in writing so that fleet size can be planned with confidence.

Who is the P-T2000D for?

The P-T2000D is aimed at operations where loads in the region of its 2000kg rating move repeatedly between defined points. Typical candidates are production plants feeding heavy components to assembly lines, manufacturers moving work in progress between process steps, and warehouses that bring racks to workstations rather than sending people into the aisles. It also suits system integrators building multi-robot intralogistics, who need a heavy-load vehicle that fits into a dispatching platform rather than running alone.

Not every site needs the same capacity, and the line is built so that it does not have to compromise. If your carriers regularly exceed what the P-T2000D is rated for, the SIASUN P-T3000D is the version to compare first. Where loads are lighter, the SIASUN P-T1500D, the SIASUN P-T1000D or the SIASUN P-T600D may suit the task better. Robots Europa will help you match the version to your actual load profile, including mixed fleets where more than one class is justified.

What is the P-T2000D used for?

1. Line-side supply: bringing heavy component carriers to assembly stations on a dispatched schedule.
2. Work-in-progress transfer: moving partly finished goods between process steps without forklifts in the production hall.
3. Goods-to-person warehousing: lifting storage racks and delivering them to picking or packing workstations.
4. Dispatch preparation: carrying finished loads from the end of the line to staging or loading areas.
5. Carrier shuttling at fixed interfaces: docking precisely with racks, carts or stations wherever repeatable hand-overs are required.
6. Fleet-based intralogistics: operating alongside other robots under IMRS 2.0, with routes optimised and layouts modelled as digital twins.

Summary

The P-T2000D turns the familiar logic of heavy handling upside down. It slips beneath a two-tonne load instead of confronting it with forks, and so keeps aisles clear and hand-overs repeatable. Its 2000kg rating, ± 10mm/±1° positioning, choice of SLAM + QR Code or QR Code navigation, 100mm lift and 6–8 hours of rated operation make it a heavy-load member of a coordinated fleet. The IMRS 2.0 platform supplies the dispatching and planning intelligence behind it, and the wider line offers a version for lighter or heavier work.
