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

A heavy casting hangs at the end of a long arm, and the lift is only half the job. What counts is how the arm brings that mass to rest, cycle after cycle, exactly where the process needs it. The SIASUN SR270A-270-2.70 (SR270A-270/2.70) is a large payload industrial robot built around that question, with a gear-driven transmission, new core components and software for many industries.

Background

SIASUN and its engineering record

SIASUN builds industrial robots and works with customers on the applications those robots run. The company has over two decades of engineering validation and thousands of project experiences. That record has earned the trust and support of customers around the world, and it ties its robot products to application know-how so that buyers receive more than a machine on a pallet.

For a buyer in the Caribbean, where a plant often cannot afford long stoppages, that kind of track record matters. A robot that has been proven in many projects is easier to plan around than one that has not. The SR270A-270/2.70 comes from that background and sits in the company's Large Payload range, within its wider family of industrial robots.

Where the SR270A-270/2.70 sits

The robot is listed in the Large Payload category, with a payload of 270 kg (595.2 lbs) and a reach of 2700mm. That pairing places it among the robots chosen when parts are heavy and the work area is wide. In this class an arm must be stiff enough to hold position under load and still move with enough agility to keep the cycle time reasonable.

This model combines rigidity and flexibility. The arm keeps its movement accurate and stops stably under high speed, heavy load and high inertia. Those three conditions are exactly what make large robots hard to build well, and they are the focus of the design.

What makes the SR270A-270/2.70 stand out among large robots?

Three things are worth a closer look: the drive, the speed and the software.

First, the drive. The robot uses a gear-driven transmission, and the overall machine rigidity is improved by 172%. Rigidity is what keeps a tool point where it should be when a heavy load pulls on the arm. A stiffer structure also settles faster after a move, which is where stable stopping under heavy load and high inertia comes from.

Second, the speed. All-new proprietary core components combine with adaptive acceleration planning algorithms to deliver a 19% speed increase. The planning algorithms have also been optimized so that continuous trajectory transitions are smoother and more seamless. On a long path that matters, because the arm flows through the corners instead of hesitating at each one.

Third, the software. Integrated multi-industry process packages are part of the offering, and they make it easy to handle a variety of manufacturing challenges. For an integrator this means less time building process logic from scratch.

On protection, the wrist carries an IP67 rating and the robot has an IP54 protection rating, which supports long-term stable and reliable operation even in harsh environments.

How does it compare with the lighter SR210A models?

The range includes arms for smaller loads. The SR210A-210/2.65 has a 2658 mm reach and a 210kg maximum payload, and the SR210A-210/3.05-DW is a sibling in the same family. The SR270A-270/2.70 is the one to look at when the part, plus its gripper, is heavier than those models carry. Each version keeps its own figures, so compare them on the product pages rather than assuming they match.

Who is the SR270A-270/2.70 for?

Plant engineers who handle heavy parts are the first group. Think of castings, large welded assemblies or bulky sub-assemblies that a person cannot lift safely and that lighter robots cannot carry.

System integrators are the second group. They need an arm with a stiff structure, a wide working envelope and ready process packages, so that the cell design can focus on tooling and safety rather than on compensating for a weak arm.

Manufacturers in demanding surroundings are the third group. The IP54 protection rating and the IP67 wrist suit shops where dust or splashing is part of daily life.

If your parts are lighter, a smaller arm may serve you better and cost less to run. In that case look at the SR50A-50/2.15, which is a smaller model in the same family.

What is the SR270A-270/2.70 used for?

1. Heavy parts handling. Robots of this class move large components between stations, conveyors and fixtures.
2. Welding cells. A rigid arm carries welding tools and keeps the torch or gun steady along the path.
3. Machine tending. The long reach lets one robot serve machines placed some distance apart.
4. Palletizing and end-of-line work. Heavy loads can be stacked and moved at the end of a production line.
5. Assembly of large units. Sub-assemblies of heavy equipment can be positioned with a repeatability of ±0.06mm.
6. Process-package applications. The integrated multi-industry process packages help when the same arm is set up for different manufacturing tasks.
