Palletizing Robots
Four-axis palletizing robots for bags, cases and cartons: 4 models, 15 to 180 kg payload and 1530 to 3130 mm reach. Four axes instead of six: the wrist has no tilt axis, and J6 turns the load through ±360°. For stacking the arm is faster than a six-axis one. If the part must be tilted or approached at an angle, use a six-axis arm.
Not sure which model fits?
Send the part weight, the reach you need and the cycle. We will name the model — and say plainly if a robot is not the right answer for it.
Palletizing robots for bags, cases, boxes, drums and sheet stacks. 4 models from 15 to 180 kg payload, reach 1530 to 3130 mm.
Common lines: cement, fertiliser and feed in 25 and 50 kg sacks, food and beverage cases, chemical drums, bricks and blocks. Four axes, not six: J1–J3 position the arm and J6 turns the product through ±360°. The wrist has no tilt axis, and for stacking the arm is faster than a six-axis one. Weight compensators take the static load off the drives — the factory credits them with a smaller footprint, lower power draw and smoother motion.
Size by the heaviest single pick including the vacuum head or clamp, and by the top of the finished stack rather than the pallet itself. A common mistake is specifying reach to the pallet corner and finding the last layer out of range.

Frequently Asked Questions
The common mistake is calculating reach to the pallet corner and finding the last layer out of range. Give us the bag or case weight, the pallet pattern and the finished stack height.
You only need six axes if the product must be tilted or placed at an angle on the way down.
4 models cover 15 to 180 kg payload and 1530 to 3130 mm reach; the RP32-180 has the longest reach, 3130 mm, and the highest payload, 180 kg.
