KUKA KR 120 R3100-2 120kg Payload 3100mm Long Reach 6 Axis Industrial Robot Arm

KUKA KR 120 R3100-2 120kg Payload 3100mm Long Reach 6 Axis Industrial Robot Arm

Overview

• • The KUKA KR 120 R3100-2 is a long reach six axis industrial robot arm that pairs a 120 kg rated payload with a 3100 mm maximum reach for cells that need distance rather than brute force.
• • That 3100 mm working envelope usually covers three stations at once, for example a machine tool, a deburring bench and a pallet, so one industrial robot arm replaces two shorter units and a linear track.
• • Pose repeatability of +/-0.05 mm to ISO 9283 holds the tool point within a few hundredths of a millimetre even at full extension, where long arm robots are usually weakest.
• • Rated payload is 120 kg, and the maximum payload of 210 kg applies when the centre of mass sits at 0 mm with a supplementary load optimised for that load case.
• • Supplementary load allowances of 300 kg on the rotating column, 130 kg on the link arm and 150 kg on the arm leave room for dress packs, camera rails and secondary tooling.
• • Weighing approximately 1105 kg on a 754 mm x 754 mm footprint, the cast base and stiff links control deflection at the far end of the 3100 mm reach.
• • Protection rating IP65 on the body and IP65/IP67 on the wrist handles dust, coolant mist and splash, which matters when the arm works deep inside a machining enclosure.
• • The robot runs on a KR C5 or KR C4 controller, so it fits existing KUKA control standards and spare controller strategy across a mixed fleet.
• • ESD compliance to IEC 61340-5-1 and ANSI/ESD S20.20 supports electronics, battery and semiconductor handling where static discharge would scrap the part.
• • Axis speeds of 120 deg/s on A1 and A3 and 260 deg/s on A6 keep long travel moves quick, so reach does not turn into longer cycle time.
• • A working ambient range of 0 degC to 55 degC allows installation in unheated workshops and near heat sources such as die casting machines.
• • Typical duty is wide envelope machine tending, remote palletizing, depalletizing and long distance transfer between conveyors and process stations.

Key Specifications

Advantages

• • The 3100 mm reach covers three stations from one base, replacing a second robot or a linear track.
• • A 120 kg rated payload with 210 kg maximum payload handles grippers, vacuum frames and heavy blanks.
• • +/-0.05 mm repeatability is held at full extension, protecting insertion and stack accuracy far from the base.
• • IP65 body and IP65/IP67 wrist protection allow the arm to work inside machining and casting enclosures.
• • 300 kg column supplementary load supports heavy dress packs without adding an external cable carrier.
• • KR C5 and KR C4 controller options simplify integration with existing KUKA cells on site.
• • ESD rated construction removes extra static control hardware in electronics and battery work.
• • A 1105 kg stiff structure limits vibration at the wrist, so heavy parts settle quickly.
• • Axis speeds up to 260 deg/s on A6 keep the long reach from costing cycle time.

Applications

• • Wide envelope machine tending across lathes, machining centres and grinders.
• • Remote palletizing and depalletizing where the stack sits away from the robot base.
• • Long distance transfer between presses, conveyors and inspection stations.
• • Die casting and foundry extraction where the arm reaches deep into the machine.
• • Battery module and electronics handling in ESD protected areas.
• • Deburring, grinding and polishing cells with coolant mist present.
• • Glass, panel and profile handling that needs span rather than payload.
• • Automotive sub assembly feeding across several fixtures in one cell.

FAQ

Q: What is the KR 120 R3100-2 used for?
A: It handles wide envelope machine tending, remote palletizing, long distance transfer and foundry extraction. Share your station layout and we will confirm reach and load case.

Q: How long is the reach?
A: 3100 mm from the robot base, the longest of the KR QUANTEC 120 kg class, which typically covers three stations from one foundation.

Q: How much can it carry?
A: Rated payload is 120 kg. The 210 kg maximum payload applies only with the centre of mass at 0 mm and an optimised supplementary load, verified in KUKA.Load or KUKA Compose.

Q: Does the long reach reduce accuracy?
A: Pose repeatability stays at +/-0.05 mm to ISO 9283 at full extension, supported by the 1105 kg structure and stiff link design.

Q: Which controllers are supported?
A: Both KR C5 and KR C4 controllers are supported, so the arm fits new cells and existing KUKA installations alike.

Q: What protection rating does it have?
A: IP65 on the arm body and IP65/IP67 on the wrist to IEC 60529, suitable for dust, coolant mist and washdown splash.

Q: Is it ESD compliant?
A: Yes. It meets IEC 61340-5-1 and ANSI/ESD S20.20, so it can work in electronics, battery and semiconductor areas.

Q: What are delivery and terms?
A: Lead time is 15 to 30 days after deposit for standard configurations. FOB, CIF and other terms are quoted on request; contact us with your destination port.
