KUKA with the new KR FORTEC

The classic industrial robots are sometimes neglected at this point. I am all the more pleased with the corresponding press releases that I can pass on. This is particularly useful because my competence in the load class > 30 kg decreases with increasing load. As can be seen from the following lines, the new KR FORTEC are very important for electromobility. Furthermore, no cobot can achieve a lifespan of up to 400,000 hours (45 years), as promised for KR FORTEC.

Technically unsurpassed in manufacturing processes with heavy and large components

Augsburg, January 2023 – The robots in the KR FORTEC ultra family set new standards in heavy payloads from 480 to 800 kg. They are ideally designed for high payloads and moments of inertia and especially meet the new requirements for electromobility.

The new KR FORTEC ultra family from KUKA consists of five robot variants – each of them suitable for a specific application. For example, the KR 800 impresses when it comes to handling loads weighing up to 800 kg. The two KR 480 variants have very long reaches of up to 3,700 millimeters. In addition, the maximum permissible mass moment of inertia for the KR 640 and KR 560 can be significantly increased with a High Inertia variant for particularly protruding grippers.

We developed the robots in the new KR FORTEC ultra family in close collaboration with our customers. They are our answer to the changing demands of the automotive industry with ever larger vehicles, very large components for electric cars or heavy batteries.”explains Wolfgang Bildl, portfolio manager at KUKA.

“Double up”: Innovative double swing arm design impresses with numerous advantages

What really catches the eye in the robots of the new KR FORTEC ultra family is the double swing arm. This innovative design ensures high rigidity and accuracy with a reduced weight at the same time. This leads to higher dynamics, optimal cycle times, lower energy consumption and lower CO2-Footprint due to the lower material consumption.

Incredibly strong. Extremely compact and light

“To cover a payload range of 800 kilograms and high mass moments of inertia, customers from other manufacturers have to resort to robots in the next higher payload class, which are significantly heavier and more expensive to purchase and maintain.“, says Wolfgang Bildl. Customers of the new KR FORTEC ultra family can spare themselves that, because the robots offer a first-class performance-to-weight ratio.

The very high mean time between failures (MTBF) of up to 400,000 hours provides customers with low spare parts costs and high availability. In addition, the new robots in the KR FORTEC ultra family meet all customer requirements for very good availability of the components as well as easy maintenance and repair. Only three different maintenance measures are necessary: ​​oil change, visual inspection and greasing of the cable set and bearing of the weight balancer. “KR FORTEC ultra is the robot with the lowest “Total Cost of Ownership” in its class”, continues Wolfgang Bildl.

Intelligent modular concept for optimal life cycle performance

A focus of the KR FORTEC ultra modular system is the use of as many structurally identical parts as possible, such as cast parts, motors and gears within the robot family. This helps to minimize the cost of storing spare parts and to standardize maintenance processes.

With the KL 5000, KUKA is also launching a new high-performance linear unit to increase the robot’s working area. With a standard length of up to 31 m, it offers great flexibility in system design. Extensions and up to four robots per KL are possible. Modular segments enable easy integration without welding. The automatic lubrication system leads to less maintenance and higher availability.

Another highlight is the new energy supply with a new K-tube and a modified interface on axis 2. This is particularly convincing due to its long life and minimized wear with a smaller interference contour and simplification of maintenance and replacement. It can also be customized to meet different requirements. Equipment that is perfectly adapted to the robot saves time and money during integration.

This nationwide in Germany at a fixed rate of €1,750 net (including arrival). The low price is possible thanks to promotion. He is constantly looking for interesting solutions and has already seen hundreds of applications. For this reason, large companies are also among his clients, who have know-how but do not know the entire market. The flat rate does not apply to companies with 250 or more employees or those based in Austria or Switzerland. You can find out more about him here.
