SIASUN SR270A-270-2.70 (SR270A-270/2.70)

Heavy automation has always involved a trade-off: the more mass a robot arm carries, the harder it becomes to move that mass quickly and bring it to rest exactly where it is needed. The SIASUN SR270A-270-2.70 (SR270A-270/2.70) is built to resist that compromise. It carries a 270 kg (595.2 lbs) payload across a 2700mm reach, yet SIASUN has engineered it to keep its movement accurate and its stopping stable under high speed, heavy load and high inertia, returning to position with a repeatability of ±0.06mm. For a production engineer weighing up a large articulated robot, that combination of strength and composure is the whole point of the machine.

Robots Europa, based in Dublin, supplies the SR270A-270/2.70 to manufacturers, system integrators and research facilities across the European Union and the DACH region. We prepare a formal quotation for each enquiry, coordinate delivery to your site and remain your point of contact for technical questions and support once the robot is in service.

Background

SIASUN and its engineering lineage

SIASUN draws on more than two decades of engineering validation and thousands of project experiences. Over that time the company has moved beyond supplying robot arms on their own and towards value-added services that pair robot products with the applications they are meant to serve. That emphasis matters for a heavy-payload machine such as this one: a robot carrying substantial loads is rarely bought as a stand-alone item, but as the centre of a production cell that has to work reliably from the first shift onwards. The SR270A-270/2.70 sits within SIASUN's Large Payload range, part of the wider family of SIASUN industrial robots that spans compact arms for light handling through to machines intended for the heaviest workpieces.

Rigidity, algorithms and proprietary components

The technical story of the SR270A-270/2.70 rests on three ideas working together. The first is mechanical: a gear-driven transmission, with which SIASUN states the overall machine rigidity is improved by 172%. The second is the drive train itself, where all-new proprietary core components are combined with adaptive acceleration planning algorithms to deliver a 19% speed increase. The third is software refinement: through algorithm optimisation, continuous trajectory transitions are smoother and more seamless, which reduces the hesitation that can appear when a heavy arm blends one movement into the next. SIASUN describes the result as a product that combines rigidity with flexibility, and the integrated multi-industry process packages extend that philosophy into the controller, so that the robot can be adapted to a variety of manufacturing tasks without starting from a blank programme.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation. SIASUN has not published the weight, power supply, controller model, axis speeds, axis motion ranges, mounting options, operating temperature, communication interfaces, package contents or how the IP54 rating applies across the whole body; these details are confirmed with your quotation.

How does the SR270A-270/2.70 combine speed with heavy-load stability?

Speed and heavy payloads usually pull in opposite directions. When a large mass accelerates, the structure of the arm flexes slightly, and when it decelerates, that stored energy shows up as overshoot or vibration at the tool. The faster the cycle, the more pronounced the effect, and the longer the robot has to wait before the next operation can begin. A robot that is quick on paper but has to pause for its payload to settle gains little in practice.

SIASUN addresses this from both sides. The gear-driven transmission and the 172% improvement in overall machine rigidity reduce the flex that causes settling problems in the first place. The adaptive acceleration planning algorithms then shape each movement to the load being carried, which is how the 19% speed increase is achieved without giving up control. The outcome SIASUN describes is accurate movement and stable stopping even under conditions of high speed, heavy load and high inertia, with a repeatability of ±0.06mm at the end of each cycle.

Smoother continuous trajectory transitions add a further benefit. In paths that string many points together, such as moving a large part around fixtures or through a sequence of stations, the robot blends one segment into the next more seamlessly. For the operator this tends to mean steadier motion, less mechanical stress on tooling and a more predictable cycle.

What do the IP54 and IP67 protection ratings mean in practice?

The SR270A-270/2.70 carries an IP54 protection rating, which SIASUN presents as the basis for long-term stable and reliable operation even in harsh environments. The wrist, which sits closest to the process and to the end effector, is rated IP67. In heavy-industry settings the wrist is frequently the part of the robot most exposed to dust, spatter, coolant or washdown, so a higher rating at that point is a practical advantage. Because the manufacturer has not stated how the IP54 figure applies across every part of the body, Robots Europa confirms the protection details for your specific environment as part of the quotation.

Who is the SR270A-270/2.70 for?

The SR270A-270/2.70 is aimed first at manufacturers who need to move genuinely heavy workpieces or heavy end effectors, where a smaller arm would be working at its limit. Automotive suppliers, producers of heavy equipment, foundries and metalworking plants, and manufacturers of large building or energy components all face tasks of this kind, often across a working envelope that calls for a long reach.

System integrators form a second group. For an integrator building a heavy handling or process cell, the combination of rigidity, stable stopping and integrated process packages can shorten commissioning, while the IP54 rating and IP67 wrist help where the cell will operate in a dirty or wet environment.

A third group consists of operations planning for higher throughput on existing heavy-handling lines, where the speed increase and smoother trajectories are the deciding factors.

Not every heavy task needs this payload, however. Buyers whose parts or tools are lighter may find a closer match among SIASUN's other arms, for example the SIASUN SR210A-210/2.65, the longer-reach SIASUN SR210A-210/3.05-DW or, for medium loads, the SIASUN SR50A-50/2.15. Robots Europa can compare the options against your application before you commit.

What is the SR270A-270/2.70 used for?

1. Heavy part handling: transferring large castings, forgings or assemblies between stations within a wide working envelope.
2. Machine tending: loading and unloading heavy workpieces at presses, machining centres and moulding machines.
3. Palletising and depalletising: stacking and unstacking heavy goods at the end of a production line.
4. Heavy assembly: positioning large sub-assemblies with the repeatability needed for consistent joining.
5. Process applications: running industry-specific tasks with the help of the integrated multi-industry process packages.
6. Harsh-environment cells: working where dust or liquids are present, supported by the IP54 rating and the IP67 wrist.
