SIASUN P-T600D (P-T600D)

Ask a production planner which loads move most often across a shop floor and the answer is rarely the heaviest one. It is the steady traffic of shelf racks, component trolleys and work-in-progress carts that keeps assembly lines supplied, and that is the work the SIASUN P-T600D (P-T600D) is sized for. As the lightest version of SIASUN's under-ride lift family, it drives beneath a carrier, raises it by 60mm, carries up to 600kg to its destination and stops within ± 10mm/±1° of its target. Instead of asking a site to rebuild its material flows around forklifts, it turns the carriers already in use into stops on an automated route.

Robots Europa, based in Dublin, supplies the SIASUN P-T600D to customers across the European Union and the DACH region. We prepare each quotation, coordinate delivery to your site and remain your point of contact for support once the robot is in service, so that planning, procurement and after-sales care sit with a single supplier.

Background

SIASUN and its under-ride lift family

SIASUN is a Chinese manufacturer of robots and automation systems whose portfolio includes autonomous mobile robots for intralogistics. The under-ride lift range is one strand of that mobile line, built as a family of versions — P-T600D, P-T1000D, P-T1500D, P-T2000D and P-T3000D — that share one design concept while covering payloads from 600 to 3,000 kg. The P-T600D opens the range at its lower end. SIASUN supports its mobile robot solutions with the IMRS 2.0 platform, which provides multi-robot dispatching, route optimisation, data analytics and digital twins for end-to-end control of a robot fleet.

The under-ride principle

An under-ride robot, sometimes called a latent lifting robot, works differently from a tugger or an automated forklift. It drives underneath a rack, cart or shelf, lifts it clear of the floor and carries it on its own back, then lowers it at the destination and drives out again. Because the carrier itself becomes the load unit, the robot can serve many stations without dedicated conveyors. In SIASUN's design, the under-ride construction gives precise access to pick-up points, while the lifting action remains smooth, stable and efficient. Multi-sensor data fusion supports high-precision task execution and seamless docking, and multi-navigation fusion with smooth switching works together with a layered safety system. The series also offers extended endurance, high drivetrain efficiency, strong carrier compatibility and fleet-level dispatching.

Technical Specifications

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

SIASUN has not published the weight, the battery type and capacity, the charging time, the travel speed, the IP rating, the turning radius, the communication interface, the box contents or the safety certifications for this version, so Robots Europa confirms each of these with you at quotation.

How does the P-T600D differ from the heavier versions in the series?

The five versions of the family share the same idea: a low under-ride chassis, a lifting mechanism, multi-sensor fusion for docking and a layered safety system. What separates them is the load they are built to carry. The P-T600D has a rated load of 600kg, the starting point of a series that extends to 3,000 kg. For a site whose carriers are shelf racks, small-parts trolleys or kitting carts, that is often the relevant class, and there is little reason to specify a larger platform for loads it will never see.

The sensible way to choose between versions is to start from the heaviest loaded carrier the robot will lift, including the weight of the carrier itself, and to keep a margin above it. If that figure sits comfortably within 600kg, the P-T600D is the natural candidate. If it does not, one of the heavier versions is the better fit, and their own pages carry their figures. Every figure in the table above belongs to the P-T600D alone and should not be read across to its siblings.

How does the P-T600D navigate and dock with its carriers?

Navigation is specified as SLAM + QR Code / QR Code. In general terms, SLAM lets a mobile robot build and use a map of its surroundings from its own sensor data, while floor-mounted QR codes give fixed reference points that a robot reads as it passes over them. Combining the two is a common approach where a site wants flexible routing in open areas and repeatable reference points at stations; QR code guidance on its own suits layouts with well-defined grid routes.

Arrival matters as much as travel for an under-ride robot, because it must position itself squarely beneath a carrier before lifting. The P-T600D achieves a positioning accuracy of ± 10mm/±1°, and SIASUN's multi-sensor data fusion is designed for seamless docking. Multi-navigation fusion with smooth switching allows the robot to move between navigation modes without interrupting a task, and the layered safety system governs its behaviour around people and obstacles.

Who is the SIASUN P-T600D for?

The P-T600D suits manufacturers whose internal logistics consists of frequent, moderate loads: electronics and component assembly, light engineering, and any production line fed by racks or trolleys from a supermarket area. It also serves warehouses and distribution operations that move shelving units or carts to picking and packing stations, and it is a practical entry point for companies introducing mobile robots for the first time, because it works with carriers rather than demanding new handling equipment.

Operations planning a fleet should consider the series as a whole, since fleet-level dispatching and the IMRS 2.0 platform allow different robots to share one site. Where loads are heavier, the SIASUN P-T1000D and SIASUN P-T1500D are the next steps up, while pallets of heavy goods, large assemblies or bulk materials point towards the SIASUN P-T2000D or the SIASUN P-T3000D. The full family is presented in our Under-ride Lift Mobile Robots category.

What is the SIASUN P-T600D used for?

1. Line-side supply: bringing component racks from a supermarket area to assembly stations on a fixed cycle.
2. Work-in-progress transfer: moving carts of part-finished goods between process steps without manual pushing.
3. Goods-to-person picking: carrying shelving units to picking stations so that operators no longer walk the aisles.
4. Finished-goods removal: taking completed loads from the end of a line to a packing or dispatch area.
5. Buffer management: shuttling carriers between storage zones and production as demand rises and falls.
6. Mixed-fleet operation: working alongside other SIASUN mobile robots under fleet-level dispatching on one site.

Pricing and Availability

Robots Europa supplies the SIASUN P-T600D on a quotation basis, because the right configuration depends on your carriers, your floor layout and the navigation approach that suits it. When you request a quotation, tell us what the robot will lift, how far and how often, and whether further robots are planned; we then propose the configuration and any non-standard customisation your scenario requires. Delivery, customs and support are arranged with the quotation. The quotation request form is available on this page.

Summary

Automation projects are often judged by the heaviest load they can handle, yet much of a factory's daily effort goes into the many moderate moves between stores, lines and dispatch. The SIASUN P-T600D addresses exactly those: a 600kg rated load, 60mm of lift, positioning to ± 10mm/±1° and a rated operating time of 6–8 hours, within a family that grows to 3,000 kg when heavier loads appear. Backed by multi-sensor docking, a layered safety system and fleet dispatching through IMRS 2.0, it lets existing carriers become part of an automated flow. Robots Europa quotes, delivers and supports it across Europe — for your project, this page is the starting point.
