SIASUN P-T3000D (P-T3000D)

Moving a fully laden carrier across a factory floor has traditionally meant a forklift, a trained driver and a clear aisle. The SIASUN P-T3000D (P-T3000D) approaches the same task from underneath. It drives beneath the load, raises it clear of the floor and carries it to the next station without an operator on board, and it does so with a rated load of 3000kg. As the top model in SIASUN's under-ride series, it is intended for the heaviest carriers the range is designed to handle. It brings automation to the part of intralogistics where manual handling tends to be slowest, most strenuous and hardest to schedule.

Robots Europa, based in Dublin, supplies the SIASUN P-T3000D to manufacturers, warehouse operators and system integrators throughout the European Union and the DACH region. Each quotation from Robots Europa is prepared for the customer's site and application. Robots Europa also arranges delivery and after-sales support for installations in Germany, Austria, Switzerland and the other EU member states.

Background

SIASUN and its under-ride series

SIASUN is a Chinese manufacturer of industrial robotics and automation equipment, and its mobile robot portfolio includes a dedicated family of under-ride lift mobile robots. The series comprises the P-T600D, P-T1000D, P-T1500D, P-T2000D and P-T3000D, with payload options ranging from 600 to 3,000 kg. This allows one platform concept to be matched to very different material-handling tasks. The P-T3000D marks the upper end of that range. It is the choice where loads are too heavy for the smaller models but the transport pattern remains the same: collect a carrier, lift it and deliver it accurately. The manufacturer also offers non-standard customisation to meet customer requirements across diverse scenarios, so the series is not limited to a fixed catalogue configuration.

Under-ride lifting and multi-sensor navigation

The defining feature of this class of robot is the under-ride principle. Instead of forks or a towing hitch, the vehicle drives beneath a rack, frame or carrier and lifts it from below. The under-ride design enables precise access to pick-up points, while the lifting action remains smooth, stable and efficient. Two further technologies support this. Multi-sensor data fusion enables high-precision task execution and seamless docking, and multi-navigation fusion with smooth switching is combined with a layered safety system. At fleet level, the robots are supported by SIASUN's IMRS 2.0 platform. The platform provides multi-robot dispatching, route optimisation, data analytics and digital twins for end-to-end control of the transport operation.

Technical Specifications

What does the P-T3000D offer over the lighter models in the SIASUN series?

The models in the under-ride series share the same operating principle, so the decision between them rests mainly on the weight of what has to be moved. The P-T3000D carries a rated load of 3000kg, the top of the series' range. This makes it the model for heavy carriers, loaded production frames and dense stock that would exceed the capacity of the smaller variants. Choosing the heaviest model where loads demand it avoids running a lighter robot at its limit. It also means a single vehicle type can serve the most demanding routes in a plant.

The specification does not trade precision for capacity. A positioning accuracy of ± 10mm/±1° is what allows a robot of this class to stop beneath a carrier and set it down again at a defined position. That matters when the destination is a production cell, a buffer station or a docking point rather than an open floor area. The lifting height of 120mm raises the load clear of the floor for transport. A rated operating time of 6–8 hours covers a substantial part of a working shift, and the series is designed for extended endurance and high drivetrain efficiency.

How does the P-T3000D navigate, and why does it matter?

The P-T3000D navigates by SLAM + QR Code / QR Code. SLAM navigation builds and uses a map of the environment from the robot's sensors, so routes can be adapted without altering the floor. QR Code markers on the floor provide fixed reference points for exact positioning. The specification lists both a combined configuration and a QR Code arrangement, which gives planners a choice suited to the layout and to how often routes change.

SIASUN's multi-navigation fusion is designed to switch smoothly between navigation sources. Multi-sensor data fusion supports high-precision task execution and seamless docking. For a vehicle carrying a heavy load, predictable behaviour on approach to a pick-up or drop-off point is as important as accuracy itself, and the layered safety system is part of that design. In multi-robot installations, IMRS 2.0 coordinates the fleet through dispatching and route optimisation. Its data analytics and digital twins help operators review performance and plan changes before applying them on the shop floor.

Who is the SIASUN P-T3000D for?

The P-T3000D is aimed at operations whose internal transport involves heavy, repetitive moves between fixed points. Typical examples are heavy manufacturing, automotive and machinery production, metalworking, and warehouses that store dense or bulky goods on carriers. It also suits system integrators who design automated intralogistics for such plants, and who value the series' fleet-level dispatching and strong carrier compatibility when integrating robots into existing processes. Companies with unusual carriers or site conditions should note the manufacturer's non-standard customisation, which Robots Europa can discuss during the quotation.

Where loads are lighter, a smaller model in the same family is usually the better fit. The SIASUN 2000 Kg Under-ride Lift Mobile Robot (P-T2000D) and the SIASUN P-T1500D (P-T1500D) cover mid-range payloads. The SIASUN P-T1000D (P-T1000D) and the SIASUN P-T600D (P-T600D) are intended for lighter material flows. The complete family is presented in the Under-ride Lift Mobile Robots category. Robots Europa can advise on the right model once the loads and routes on your site are known.

What is the SIASUN P-T3000D used for?

1. Production line supply: delivering heavy components on carriers from storage to assembly stations on schedule.
2. Work-in-progress transfer: moving loaded frames between machining, welding or assembly cells without forklift traffic.
3. Warehouse transport: shuttling dense or bulky stock on racks between storage zones and dispatch areas.
4. Buffer and staging management: placing carriers precisely at buffer positions and retrieving them when the next process step calls for them.
5. Finished goods removal: collecting completed heavy assemblies from the end of the line and taking them to inspection or packing.
6. Fleet-based intralogistics: operating alongside other robots under IMRS 2.0 dispatching for coordinated, plant-wide material flow.

Summary

The SIASUN P-T3000D replaces the forklift-and-driver approach to heavy internal transport with a robot that works from underneath the load. It drives beneath a carrier, raises it by 120mm and delivers up to its rated 3000kg to a position defined to ± 10mm/±1°. SLAM and QR Code navigation, multi-sensor fusion, a layered safety system and fleet control through IMRS 2.0 make it the heavy-duty end of a series that also includes lighter siblings for smaller loads. For organisations that want their heaviest material flows automated and planned to their own site, with Robots Europa handling the quotation, delivery and support, this page is the starting point.
