The maintenance philosophy in the past was repairing only what is not working.Full refurbishment and investigations were not carried out.
This philosophy is changed into “General Repair” and “Partial Repair”.
Import equipment general repair concept
PTTS can achieve "old as new", the process as below:
Caster units receive —— Cleaning —— Incoming Inspection —— Frame Opening —— Frame sand blasting
Frame welding and machine —— Frame assembling —— Assemble comfirm —— Final Inspection —— Caster units Release
Therefore, we set up a special inspection team to conduct a comprehensive inspection of the offline equipment and form an inspection report, and then the planning department makes a detailed maintenance plan to accurately describe the maintenance category of the equipment.
