Quality Control
For the purpose of “to provide high level cranes for advanced users”, SINOKOCRANES is built on its European crane technology, pursuing reliable and stable quality. The strict, comprehensive quality control system ensure each of our crane products to be safe, functional, elegant and satisfied to our users.
We have professional and rich-experienced inspection and test team. We guarantee that each of our crane has been checked by our quality control engineers.


Steels Detection
All steel after the arrival shall be inspected on material, size, thickness. Thickness detection by ultrasonic thickness. Material report will be issued by the inspection team. If the QC group found unqualified, the steel cannot put in storage. Return notice issued by the inspection engineer directly to purchasing department.


Ultrasonic Thickness Detector


Weld Inspection
All the joint panel welding seam, web plate fillet weld are strictly according to drawings and European Crane Process Standard. Use RT/MT/UT/PT nondestructive inspection and issue relevant inspection report. Measure and mark the unqualified parts and let no doubts pass.


Magnetic Defect Detector


Wheel hardness, roughness test
All the wheels and shaft machining parts need strict inspection for hardness, roughness, dimensions etc. Ensuring every parts conform to design specifications.


Leeb Hardness Tester


Paint film thickness detection
Advanced surface treatment process and  Epoxy zinc-rich coatings to ensure our crane won’t have paint falling off or color fading. The key is our strict inspection and quality control.


Paint Film Thickness Gauge


Pre-install Inspection
Although we have thorough quality control to each part in the producing process, we take pre-install inspection to every crane before delivery. The crane will be pre-installed and measured as per inspection process and design parameters. The key inspection parts are span, length, beam deflection etc.


Level Gauge

Third Party Inspection
SINOKOCRANES not only has complete process inspection and delivery inspection, for the critical components, the factory invite authority organization to do the third party inspection, ensuring that each component reaches design requirements.
Also the factory can do third party inspection under user’s requirement by SGS, TUV or BV international inspection organization.





Site inspection
SINOKOCRANES have a professional installation team with rich crane installation experiences. Different mature installation proposal suit for different workshops and steel structures. Before installation, our site engineer will check and measure the workshops, such as the H-beam height, workshop height, span, installation accuracy etc to ensure the smooth and successful crane installation.
