Certification first
Insist on a Grade-A (A-level) manufacturing license and ISO9001/14001/45001. For export, CE-capable and third-party inspection (SGS/TÜV) matter more than a low price.
Track record beats brochures
Ask for reference projects in your industry and region. A maker supplying CREC/CCCC/CSCEC and exporting Belt & Road projects (e.g. gantry cranes for HSR) has proven engineering, not just a catalogue.
Customization capability
Real lifting needs are site-specific. Confirm the supplier handles non-standard duty, span and environment — from overhead to RTG to mine hoists.
After-sales is the real product
Look for local spare-parts stock, documented response time and commissioning support. Tongyu backs every Lugang order with a 1h-response promise and full spare-parts supply.
Red flags
- No manufacturing license or cannot show it.
- Vague on weld inspection / steel grade.
- Won't provide reference contacts.
- Price far below market with no engineering questions asked.
