Semi-Auto Bag Palletizer
Model 72SAB
Automation for Low Volume Lines
Here’s an easy upgrade from manual bag palletizing that can eliminate heavy lifting, increase your production, accommodate product variations, and deliver consistently square, securely formed pallet loads. It’s a robust machine built to handle heavy loads with ease and provide dependable automation for years to come.
A Simple Bag Palletizing Solution for Low Volume Lines
This palletizer offers a simple and economical solution to automating your manual operation. By eliminating manual lifting of heavy industrial bags, you can improve safety, reduce costs, and increase production speed. Just one operator is required to position bags on the transfer table and palletizing is automatic…layers are lifted, squared, and stacked into secure pallet stacks. The palletizer’s ergonomic design makes it easy for the operator to palletize without fatigue and maintain top line efficiency.
Although built for low volume production, the M72SAB offers the same quality construction and proven production features that make A-B-C palletizers a valued addition to the packaging line. With our trademark robust design, counterweighted elevator table, variable frequency drive and layer squaring as standard features, you’ll be assured of top production and long machine life with less maintenance. With the option to upgrade to full automation, this palletizer will provide future-proof production on your packaging line.
Key Features That Benefit Your Production

All production at floor level reduces cost of operation
This palletizer replaces the tiresome task of manual palletizing, reducing costs and ensuring a safe production environment. The operator simply transfers the product from the conveyor onto the accumulation table, then activates palletizing. The layer is automatically lifted, squared, and placed precisely on the pallet stack.
Quality built to provide top production on your packaging line
- Heavy gauge steel frame
- Counterweighted and frequency driven elevator table removes load stress from the drive motor, ensuring smooth transport and long motor life
- Stainless steel, tapered stripper plate ensures stable layer transfer
- Elevator table is supported by crossbar reinforcing beams to reduce case friction and eliminate table load stress

Rugged mechanical load transfer and counterweighted elevator table
The elevator table utilizes stainless rollers to reduce friction, allowing bags to move smoothly without compressing or shifting the contents. The table edge has a tapered design to allow bags to glide smoothly from table to pallet. Product layers are transferred by dual chain-driven mechanisms that provide powerful and consistent load transfer.
The counterweighted design provides stable vertical transport with soft start and stop. This design maximizes drive motor performance to ensure long operating life.

Accommodates product and layer variations to build perfect palletloads
The self-adjusting layer retainer sweep bar compensates for bag variations and ensures a positive sweep. Each layer is held firmly to retain it squarely during the deposit cycle. The sweep bar automatically centers each layer on the pallet, eliminating additional adjustments during changeover.
For some applications, a rear layer retainer plate and two side layer squaring plates are utilized to square the layer and ensure that it is centered on the pallet.
Layer squaring during placement builds strong and secure pallet loads for optimum product protection throughout distribution.
A system that grows with your needs
The M72SAB has a modular design that allows product feed from any direction. New product and pallet configurations require no downtime or changeover…just feed the new product and the operator arranges the new pattern. If your production needs change, this semi-automatic palletizer can be modified to provide automatic operation.
