KUKA KR 70 R2100 70 kg Payload 2101 mm Reach 6-Axis Heavy Duty Industrial Robot Arm for Palletizing

Overview

• • The KUKA KR 70 R2100 is a heavy duty industrial robot arm rated for a 70 kg payload, with a maximum payload of 85 kg available at reduced load centre distances.
• • A 2101 mm maximum reach lets a single 2101 mm reach robot serve two machines or reach the far side of a full pallet position without a linear track.
• • Pose repeatability of ±0.05 mm according to ISO 9283 supports accurate placement in palletizing, machine tending and assembly sequences.
• • The KR C4 controller is operated through the KUKA smartPAD, which puts robot, motion and safety logic on one familiar hand-held interface.
• • The arm carries protection rating IP65, and the arm and in-line wrist are released to IP65 / IP67 for dusty, humid and wash-down areas.
• • Floor, ceiling, wall and desired-angle mounting are all approved, so the heavy duty industrial robot arm fits existing cell layouts instead of forcing a rebuild.

Technical Specifications

Advantages

High Payload in a Compact Footprint

• • The 70 kg rated payload covers grippers, palletizing tools and multi-part fixtures that overload smaller general-purpose arms.
• • A 603 mm x 480 mm footprint and approx. 536 kg weight keep foundation work modest for a machine of this payload class.
• • Rated payload is set at 70 kg to optimise dynamic performance, and up to 85 kg maximum payload is usable at reduced load centre distances.

Balanced Axis Dynamics

• • Axis speeds of 180, 158 and 160 °/s on A1 to A3 keep heavy transfers moving without long dwell times.
• • Wrist speeds of 230, 230 and 320 °/s on A4 to A6 give fast tool reorientation at the end of each approach path.
• • A6 rotates through ±350°, which reduces cable twist and shortens cycle time on repetitive pallet patterns.

Proven Protection and ESD Compliance

• • Arm protection rating IP65 with IP65 / IP67 on the arm and in-line wrist resists dust, coolant spray and wash-down cleaning.
• • ESD behaviour is declared to IEC 61340-5-1 and ANSI/ESD S20.20, which matters in electronics and paint-adjacent areas.
• • Continuous operation is released from 0 °C to 55 °C, covering unheated halls as well as warm foundry surroundings.

Flexible Mounting and Wide Motion Range

• • Floor, ceiling, wall and desired-angle installation are approved, so the 6-axis robot can hang above a machine or work inverted.
• • A1 travel of ±185° and an A3 range from -120° to 165° open a wide working envelope for a 2101 mm reach arm.
• • A 20 kg supplementary load on the arm allows dress packs and camera brackets to be carried without eating into payload.

Controller and Load Verification

• • The KR 70 R2100 runs on the KR C4 controller with KUKA smartPAD, giving one integrated platform for robot, motion and safety programming.
• • Each load case can be checked in KUKA.Load, which documents tool mass, centre of gravity and inertia before commissioning.

Applications

• • Palletizing and depalletizing of cartons, bags, pails and drums at end-of-line stations.
• • Machine tending for CNC lathes, machining centres, presses and injection moulding machines.
• • Handling of castings, forgings, billets and other heavy machined parts between stations.
• • Assembly of large frames and sub-assemblies where a 70 kg payload robot positions the part, not just the tool.
• • Grinding, deburring and fettling of cast components with tooling carried on the flange.
• • Die casting and foundry extraction, where the IP65 / IP67 wrist option handles heat, dust and release agents.
• • Food, beverage and building-material lines that need repeated heavy-case palletizing in a small footprint.
• • Automotive powertrain and battery-pack handling, including in-line transfers above conveyor level.

FAQ

Q1. What is the difference between rated payload and maximum payload?
The robot is designed for a rated payload of 70 kg to optimise dynamic performance. With reduced load centre distances, higher loads up to the 85 kg maximum payload may be used, and each load case must be verified in KUKA.Load.

Q2. How accurate is the KR 70 R2100?
Pose repeatability is ±0.05 mm measured to ISO 9283, which is sufficient for palletizing, machine tending and jig-based assembly.

Q3. Which controller and teach pendant are used?
The arm runs on the KR C4 controller and is programmed with the KUKA smartPAD hand-held pendant.

Q4. Can it be mounted on the ceiling or at an angle?
Yes. Floor, ceiling, wall and desired-angle mounting positions are all released, which suits overhead machine tending and inverted cells.

Q5. What protection rating does the arm have?
The protection rating is IP65, and the arm and in-line wrist are available to IP65 / IP67 for dusty, humid or wash-down environments.

Q6. How much space and load does the installation need?
The footprint is 603 mm x 480 mm and the robot weighs approx. 536 kg, so the foundation and anchor pattern should be sized to that weight plus tooling and work-piece mass.
