Dear Thawatchai Todee,
Thank you for your feedback.
I understood the reason, thank you.
Could you please precise how are you processing now ?
What kind of technic do you use to (de)palletize?
Do you know that we can also provide gripping heads ( to be able to fix our gripper tubes on it) ?
Please find attached our docs and do not hesitate to contact me for any further information.
