Making light work of it all.
KUKA’s low payload category
from 5 kg to 16 kg.
KUKA robots with low payloads demonstrate unique strengths in bonding,
sealing, foaming and all tasks requiring high path accuracy. In arc welding,
KUKA robots for low payloads boast the best acceleration values on the
market. Even light work such as component testing, small-part assembly or
grinding, polishing, assembly as well as machine loading and unloading
are in the best of hands when performed by KUKA robots of the low payload
category. With optimal reach and payload coverage, this range of robots
offers a level of performance that is hard to beat.

Advantages and functions
LOW MAINTENANCE. KUKA robots offer the longest maintenance intervals on the market, at around
20,000 operating hours, ensuring maximum productivity.
ROBUST. Systematically designed for durability, KUKA robots operate reliably over long periods even
under extreme conditions.
QUALITY STANDARD. To ensure a good return on investments over many years, KUKA bestows the
greatest importance to quality – in every component, gear unit and axis.
IDEAL FORM. Their optimal balance of reach, weight, speed and energy consumption qualifies KUKA
robots for a large number of both familiar and new applications.
99.995 % AVAILABILITY. KUKA robots for low payloads allow long-term planning and cost estimation.
PATH ACCURACY. KUKA robots set standards with their unparalleled precision in welding, bonding and
sealing, while attaining utmost repeatability and unbeatable cycle times.
FLEXIBLE. The functional diversity of KUKA robots means there are no limits on their application
potential. In addition, they can be individually adapted, e.g. by means of arm extensions.

Features and advantages
DURABLE. Protected routing of the arc welding dress package
in the robot arm results in a longer service life and prevents
the dress package from buckling.
PROCESS-OPTIMIZED. Reduced disruptive contours and large
distance between axis 5 and the robot flange allow welding
deep within the workpiece, enlarge the workspace and offer
better accessibility, even in the case of large workpieces.
RESILIENT. Robust arm design with double-sided mounting of
the robot wrist ensures reduced vibrations during welding and
is resilient in the case of minor collisions.
FAST. Axis 6 is an infinitely rotating axis that does not need to
turn back or “unwind”.
FUTURE-PROOF. Large opening with a diameter of 50 mm,
suitable for all commonly-used dress packages, leaves enough
space for additional fluids in the dress package – making it
even suitable for water-cooled torches.
SIMPLE HANDLING. The very low weight enables high dynamic
performance, simple installation and effortless mounting on
the ceiling.

Features and advantages
SPECIALIZED. Ideally designed robot for arc welding
applications with a payload of 16 kg and a reach of up
to 1,636 mm.
PROTECTED. 58 mm opening in the arm and wrist allows the
arc welding dress package to be routed in the protective
interior of the arm.
FLEXIBLE. Both torsion-type dress packages and infinitely
rotating arc welding dress packages are possible – for better
component accessibility and simplified offline programming.
SPACE-OPTIMIZED. Low disruptive contours of the robot and
the streamlined design of the wrist ensure high accessibility,
even in confined spaces.

Features and advantages
SPECIALIZED. Ideally designed robot for arc welding
applications with a payload of 8 kg and a reach of up to
2,016 mm.
PROTECTED. 50 mm opening in the arm and wrist allows the
arc welding dress package to be routed in the protective
interior of the arm.
FLEXIBLE. Both torsion-type dress packages and infinitely
rotating arc welding dress packages are possible – for better
component accessibility and simplified offline programming.
SPACE-OPTIMIZED. Low disruptive contours of the robot and
the streamlined design of the wrist ensure high accessibility,
even in confined spaces.

Advantages and functions
VERSATILE. The intelligent payload and reach intervals allow simple, reliable planning. KUKA also offers
shelf-mounted robots covering a payload range from 16 kg to 270 kg.
LIGHT. KUKA shelf-mounted robots stand out for their low weight. They can be installed directly on
machines with minimum effort, while saving space.
DEEP REACH. KUKA shelf-mounted robots are designed for an especially large downward reach, optimum
access the workspace from above. Due to their low height, they require little space above the
robot base.
FAST. Lightweight, KUKA shelf-mounted robots achieve high dynamic performance and very short cycle
times. Enabling higher productivity and cost-effectiveness with rapid payback.
RELIABLE PLANNING. Each KUKA robot family shares an identical mounting base hole pattern. This allows
different shelf-mounted robots to be used on machines of different sizes – without any additional planning
measures.

Features and advantages
ALL-ROUNDER. Safety, Robot, Logic and MotionControl – the
KR C4 combines everything in a single controller allowing
effortless control of the entire system.
UNIVERSAL APPLICATION. The open architecture of the KR C4
can control not only KUKA robots but also external axes – for
maximum flexibility, scalability, performance and openness,
in minimum space.
FOR ALL PAYLOADS. The KR C4 is the uniform controller for
all KUKA robots, ranging from the low to high payload range
categories.
COMMUNICATION TALENT. In addition to its own robot language KRL, the KR C4 understands the language of the CNC
machining world (G-code) and the language of PLCs, enabling
it to communicate directly with your Siemens® or Rockwell®
controller.
ROBUSTNESS. The consistent choice of durable components
and well-designed cabinet ensure long-term, reliable
operation, even in extreme conditions.
±0.002 SEC I/O RESPONSE TIME. Secure data exchange
measured in milliseconds forms the basis for new safety
concepts in human-machine cooperation.
ENERGY-EFFICIENT. The new energy management system
allows the energy consumption of the controller to be
reduced by up to 95 %* in standby mode. The improved cooling concept, combined with a temperature-controlled fan,
further reduces the power dissipation of the controller, while
making operation considerably quieter.
