Decision guide

Gantry vs robotic palletizer

The short answer: choose a gantry for a low- to medium-speed line with cases up to 65 lb and stable pallet patterns. Choose a robotic palletizer when cases are heavier, the line is faster or SKUs and patterns change often. At Odecopack the gantry starts at $99,000 and the robot at $165,000, both excluding installation.

Decision process

How to choose in five steps

The same order our engineers work through on every palletizer quote.

  1. Weigh the heaviest case

    This is the first fork in the road. At 65 lb (32 kg) or less, the gantry stays on the table. Above that, the answer is a robotic palletizer. The gripper counts against payload too, so a case close to the limit needs a closer look.

  2. Measure the rate you actually need

    Take sustained cases per minute at the end of the line, including peaks and pallet changes. A gantry is built for low- to medium-speed lines; when the rate outruns it, a robot's faster cycle times earn their price.

  3. Count SKUs and pallet patterns

    List every case size and pattern you run, and what is coming in the next few years. Stable, repeatable patterns suit a gantry. Frequent changes and mixed patterns favor an articulated robot.

  4. Map the real layout

    Mark infeed conveyors, pallet positions, empty-pallet supply, full-pallet removal, stretch wrapping, guarding and forklift paths. Floor space is decided here, not on a brochure.

  5. Compare installed cost and payback

    Compare equipment, installation, integration and maintenance against the labor removed. On the default assumptions in our ROI calculator, the gantry pays back in about 14 months and the robot in about 23 months. Then test a conservative case with your own numbers.

Avoid these

Common mistakes when choosing a palletizer

  • Choosing on list price alone

    Both starting prices exclude installation. The comparison that matters is the installed project: equipment, installation, conveyors, guarding and controls integration.

  • Forgetting the gripper weight

    Payload is case plus tooling. A case that looks comfortably under the gantry's 65 lb ceiling can end up near it once the gripper is included.

  • Sizing for today's SKUs only

    A gantry that fits today's single pattern can become a constraint if new case sizes or mixed pallets are already on the roadmap. Ask what the line will run in three to five years.

  • Assuming heavier always means gantry

    General guides often say gantries are the choice for heavy loads. That depends entirely on the machine. Our gantry is rated to 65 lb; heavier cases go on our robotic palletizer.

  • Comparing peak speed instead of sustained output

    Rate claims are usually best-case. Size the system on sustained output with your heaviest, hardest SKU and real pallet changes.

Run both options through your own numbers

The ROI calculator runs either machine on your labor cost, shifts and case weight, and flags when a case is too heavy for the gantry.
