KUKA KR 70 R2100

The KR 70 R2100 puts a 70 kg payload on a 2101 mm reach across six axes, KUKA's take on moving heavier parts without a full heavy-robot footprint. Its tagline calls it a compact heavy payload robot for demanding handling jobs, and the summary lists it as common on heavy machine tending lines. Repeatability sits at 0.05 mm, tight enough to place those loads consistently.

Press tending is where this arm earns its keep, and the record flags it as a good match. The 70 kg payload feeds parts through a press, and the record highlights strong wrist torque for handling asymmetric loads. That same capacity carries into machine tending and heavier palletizing, where part weight sits at the top of the range.

General material handling rounds out the job list, with the 2101 mm reach covering a wide work envelope. Six axes handle the orientation of loads that don't sit square to the flange, and the 0.05 mm repeatability holds placement shot to shot. The record points to robust design for continuous multi-shift running.

Mounting options span floor, ceiling, wall, and inclined positions, so the arm can sit where the cell layout wants it. At 536 kg it needs foundation planning, a point the record raises as a consideration, so a solid base plate and careful leveling earn their place during commissioning.

The KR C4 controller runs the cell. The arm carries a rated IP65 body / IP67 in-line wrist. Introduced in 2020, it lands among KUKA's six-axis industrial arms aimed at continuous handling duty.
