FAQ
How to handle cracks found in structural parts?
Stop the machine and evaluate immediately when cracks are found. Minor cracks on non-load-bearing surfaces can be repaired by professional welding (with preheating and post-heating); cracks in load-bearing zones or propagating cracks require replacement of the whole part. Operation with defects is prohibited.
How to ensure precision when installing structural parts?
Use specified lifting points to prevent deformation; clean mating surfaces and apply sealant; tighten crosswise in diagonal sequence to the specified torque; after installation, check levelness deviation ≤0.1mm/m and concentricity per technical requirements.
What are the daily maintenance points for structural parts?
Check daily for loose connection bolts; weekly check welds and stress concentration areas for cracks; monthly clean the anti-corrosion coating and touch up damaged areas; keep lubrication points supplied to avoid dry friction aggravating structural fatigue.
