KUKA positions the KR 40 PA as its smallest and lightest palletizing robot, purpose-built for the Euro pallet workhorse job: 40 kg of payload stacked to net heights of 1.6 m on a 2091 mm reach, at up to 56 cycles per minute - speed figures the low arm weight directly buys, since every kilogram the axes swing is a kilogram the cycle does not.

Why a dedicated four-axis palletizer?

Because a six-axis arm stacking boxes wastes three joints on motion palletizing never needs. The four-axis PA kinematics concentrate stiffness where stacking demands it, holding 0.05 mm pose repeatability per ISO 9283 through A1 sweeps of 155 degrees, and the slim base with integrated energy supply shrinks the interference contour enough for compact cells that a full-size PA robot would crowd out.

Entry palletizer or QUANTEC companion?

Companion: the KR 40 PA serves compact Euro-pallet cells while the KR QUANTEC PA family - up to 240 kg and 3195 mm - handles the heavy layers, all on the KR C5 controller with KUKA iiQoT connectivity. IP65 sealing including the in-line wrist suits dusty end-of-line corners, and maintenance stays low because every component was chosen for low wear at the 56-cycle duty the machine was built to sustain.
