ARPG – Palletizing grippers

ARPG – Palletizing grippers

Features and Benefits
High Energy Density (Payload to Gripper Weight Ratio)
Doesn’t require large robots to palletize lightweight bags.
• Versatility
Gripper width easily adjusts and locks with our patent pending Self-Locking Rotary Handwheel.
• Failsafe Payload Support
Will not lose payload during loss of power or air.
• Robustness
Engineered construction with select materials provides maximum strength in any industrial environment.

Pneumatic bag grippers


Pneumatically actuated mechanism to clamp the bags from the sides, keeping bag and tool centered to prevent misalignment and maintain palletizing consistency. These clamps are manually adjustable ± 95mm to accommodate different bag widths.
The grippers are hard coated for protection in extreme environments.


  • A sensor to verify presence / absence of the bag in the gripper.
  • Capable of 20+ cycles per minute, dependent upon robot and distance traveling.
  • Pre-configured for robots with an ISO 125 bolt pattern for tool mounting or many other options but able to be used without a robot and all I/O included for ease of integration.
  • All electrical interconnections between the valves, sensors and the junction box as well as the electrical cable and connector are provided for easy robot integration.


  • A pneumatic mechanism for moving empty pallets into the loading position. (Note: mechanism will handle empty pallets only).
  • Vacuum cups operated by a single generator to pick up a 1016mm x 1219mm (40″x 48″) slip sheet.
  • Collision sensing device options available
  • Quick connect/disconnect devices for robotic attachment available
