A Bag Pallet Lifter Palletizer refers to automated or semi-automated systems designed to lift, orient, and stack bags (sacks) onto pallets. These systems are essential in industries like agriculture, chemicals, and food production, where manual handling of heavy bags (often 20kg to 50kg) is a major safety and efficiency bottleneck.
These systems take bags directly from a conveyor belt and stack them according to a pre-programmed pattern.
| Type | Best For… | Key Feature |
| Robotic Palletizer | Flexibility and multi-line use. |
Uses a robotic arm with a specialized gripper to handle different bag sizes and complex patterns.
|
| High-Level Palletizer | High-speed, high-volume production. |
Bags are conveyed to a high platform, formed into a layer, and then dropped/pushed onto the pallet. Very fast (up to 40+ bags/min).
|
| Low-Level Palletizer | Medium speed and tight spaces. |
Operates at floor level. Easier to maintain and more affordable than high-level systems, though slower.

If your goal is to assist a human operator rather than replace them, you are likely looking for a Vacuum Tube Lifter.
How it works: A vacuum pump creates suction in a large tube. The operator uses a handle to move the bag, and the vacuum does 100% of the heavy lifting.
Benefits: Prevents back injuries, allows one person to do the work of two, and can handle porous bags (paper, plastic, or woven).
Reach: Often mounted on a jib crane or a bridge crane to cover a wide palletizing area.
End-of-Arm Tooling (EOAT): For robots, the gripper is crucial. Finger grippers wrap around the bag to ensure it doesn’t slip, while vacuum grippers are better for plastic/non-porous bags.
Bag Flatteners: Before palletizing, bags often go through a “flattener” (two conveyors pressing the bag) to redistribute the contents. This creates a flatter bag and a much more stable pallet stack.
Layer Squaring: High-end palletizers use “squaring plates” to push the bags together on all four sides before placing the layer, ensuring no overhang.
Food & Beverage: Flour, sugar, grains, and pet food.
Construction: Cement, grout, and sand.
Chemical/Agri: Fertilizers, plastic pellets, and seeds.
