Creating Passion: Your Responsibilities
Reponsibilites
To carry out abrasive blasting operations for structural and precision components of tower cranes and drive systems to achieve the required surface cleanliness, roughness (anchor profile), and preparation standards prior to painting or coating processes. The Shot Blaster ensures proper surface preparation for long-term coating adhesion and corrosion resistance, as per technical and quality specifications (e.g., ISO 8501-1).
Surface Preparation
- Perform shot/grit blasting on fabricated assemblies, machined components, or drive housing components. - Ensure uniform blasting to remove rust, scale, weld slag, oil, and previous coatings.
- Achieve the required surface cleanliness grade (e.g., Sa 2.5 / Sa 3) and anchor profile as specified in the technical specification sheet or paint system.
Pre-Blasting Inspection
- Verify material identity using heat code / part ID prior to blasting.
- Ensure weld joints, oil marks, burrs, and surface damages are appropriately rectified before blasting.
- Mask or protect critical surfaces (e.g., machined areas, threads, nameplates) from abrasive media using suitable masking tape or shields.
Equipment Operation & Setup
- Operate manual/semi-auto blasting machines, including blasting pots, hoses, nozzle guns, recovery system, and dust collectors. - Adjust air pressure, nozzle size, and abrasive flow as per job card / SOP.
- Monitor compressor operation and airflow consistency during the job. - Ensure adequate lighting and ventilation inside blasting booths.
Abrasive Media Handling
- Load, monitor, and maintain abrasive blasting media (e.g., steel shots, aluminum oxide).
- Ensure media cleanliness by screening and rejecting contaminated or broken grits. - Inform supervisor for replenishment of low media stock.
Post-Blasting Inspection
- Conduct visual inspection of blasted surface for cleanliness, roughness, or missed areas.
- Reject and reblast areas that show flash rust, oil
