Dear Khun Pattheera,
There is scenario where customer provide pallet with overhang requirement during quotation stage. But when in actual operation, the pallet they use is without overhang or only with a little overhang. In this scenario, the system will run smoothly for many years without any issue.
In this new project, the customer may provide us pallet with excessive overhang similar to what they have provided before in IRPC project. But this time if they really use the excessive overhang pallet in actual operation, the orbiter cart may not operate smoothly. That is the reason we need the orbiter cart supplier to advise and we will document their advice in our record.
Please treat this as new project and seek their advice for the pallet excessive overhang concern.
