KR FORTEC ultra

The heavy-duty robots, with payloads of up to 800 kg, offer maximum performance in the smallest possible space and feature fast and precise handling of large components with a high moment of inertia.

Developed for high moments of inertia when handling heavy and large workpieces

From battery handling to gigacasting. In production, the requirements with regard to payload and reach are increasing sharply in combination with ever higher moments of inertia of the workpieces. The KR FORTEC ultra robots were designed to meet these requirements with maximum efficiency in the smallest possible space. As an intelligent modular and shared parts concept that allows the optimum robot to be selected for an application and adapted in the field. Leading the way in performance, cost-effectiveness and flexibility. Both now and in the future.

* KUKA is continuously working on expanding its robot portfolio to meet customer expectations, e.g. in the automotive sector and general industry. The special Foundry variants and the robot versions for machining applications will be available for ordering soon.

The lightest in its class. But incredibly strong, rigid and fast. 

KR FORTEC ultra robots have been developed in close cooperation with customers to ensure that the most demanding requirements in the area of heavy payloads are easily met.

The KR FORTEC ultra is the robot with the lowest total cost of ownership in its payload class.

Wolfgang Bildl, Portfolio Manager at KUKA.

480 - 800 Load capacity [kg]

2800 - 3700 Reach [mm] (arm length)

Provides maximum performance wherever extreme payloads with high moments of inertia are involved

Incredibly strong. Extremely compact & light.

The KR FORTEC ultra family offers a payload-to-weight ratio that is unprecedented in this payload category. With a payload capacity of 800 kg, it weighs 2.4 t, and with a payload capacity of 640 kg, it weighs just 2.2 t.

High Payload & High Inertia.

The extremely rigid design with double link arm system, powerful motors and heavy-duty gear units enables precise and fast handling of heavy, large-format parts with high moments of inertia.

Flexible cell and system planning

The streamlined disruptive contour, an extended working envelope in front of, above and behind the machine, as well as the small footprint enable use in confined cells, but also open up completely new cell concepts.

Cost-effectiveness redefined

Thanks to the optimum relationship between weight and payload capacity, the economical start-up and maintenance concept, and the reduced number of spare parts, the KR FORTEC ultra family ensures a significant reduction in operating costs.

Highest performance

Due to its motion algorithm and the resulting higher axis acceleration, as well as the shortest positioning time in its class, the heavy-duty robot delivers even higher dynamic performance and shorter cycle times.

Convertible payload capacity & 2nd life ability

The robots of the KR FORTEC ultra family can be converted and upgraded at any time in terms of payload capacity and mass inertia to suit new tasks. This allows the robot to be reused in new applications and guarantees maximum flexibility in production.

Optimized design for application versatility

In addition to the standard waterproof and dustproof in-line wrist (wrist axes A4-A6 in IP65 and IP67 versions), the robot also offers a Foundry option for use in particularly hot, wet or dirty environments.

Climate-friendly robotics

With its low energy consumption, which includes state-of-the-art drive technology and the latest software and controller technology, the second life-capable industrial robot with long service life and reduced footprint offers a climate-friendly overall robotics package.
