Where carton and block lines run heavy and fast at the same time, the 320kg payload palletizing robot arm keeps both numbers. It reaches 3159mm and stacks to 2737mm, so tall pallets are built without repositioning the base, and it still delivers 1270 cycles per hour, 53 percent faster than the previous generation of the same size. The extra payload covers heavier grippers, multi-carton clamp heads and the concrete block and brick tooling that lighter arms cannot carry. A 4 axis design keeps the wrist rigid under load, while the 75mm hollow bore and 200mm flange accept large gripper mounts without adapters. The 308mm wrist height and IP54 body suit crowded halls with low ceiling clearance.

Q: What loads can the 320kg payload palletizing robot arm take?
A: 320kg covers product plus gripper. That margin fits multi-carton clamps, concrete block heads and brick tools that exceed the range of lighter models.
Q: How high does it stack?
A: The 3159mm reach builds pallets up to 2737mm on 1300 x 1300mm and 1600 x 1600mm patterns, so a full height pallet is finished in one station.
Q: What throughput should I expect?
A: 1270 cycles per hour at rated payload on the standard measuring pattern, which is 53 percent faster than the previous model of the same size.
Q: Which gripper mounts fit?
A: The wrist uses a 200mm flange with a 75mm hollow bore, so large clamp heads and block grippers bolt on directly and their cables run inside the arm.
Q: How does it handle heavy layers without drift?
A: The wrist allows 160 kg m2 of inertia on the rotation axis and repeats to +/-0.05mm, so a heavy layer lands on the pattern without shifting.
Q: Is IP54 enough for block plants?
A: Yes for normal operation, and the wrist is IP67. For high pressure wash-down areas we supply an added protective cover set.
Q: Can the 320kg unit replace two smaller robots?
A: On many lines it does, because the payload covers a wider gripper and the reach covers two pick positions, cutting one robot and one controller from the layout.
Q: What is the delivery and support scope?
A: Typical delivery is 35 to 50 days from deposit. We supply layout drawings, anchor plans, parameter backup and remote commissioning support.
