Q What technical measures are taken for noise control?
A We reduce operating noise by precision machining of the link plate profile, optimizing the tolerance fit between rollers and pins, and using oil-impregnated bearings or self-lubricating materials (such as engineering plastic rollers). For high-speed transmission, we can also provide pre-stretching to reduce noise caused by vibration.

Q Can you provide 3D models or CAD drawings for the chains?
A Yes. For standard items, we can provide 3D models in STEP or IGES formats and CAD drawings in PDF. For custom products, after signing an NDA (Non-Disclosure Agreement), we will provide exclusive drawings based on the confirmed design to help you with equipment adaptation.
-
Q What is the approximate service life of the chains?
A Service life is heavily influenced by the load rate, lubrication, and maintenance frequency. Under normal load and with regular lubrication, our G80 lifting chains typically maintain efficient operation for thousands of hours. We recommend regularly inspecting the chain links for wear. Mandatory replacement is required when the diameter wear exceeds 10% of the original diameter.

Q What material are your chains made of? How is the rust resistance?
A Our standard high-strength chains are typically crafted from premiun alloy steel(such as 20Mn2A,25MnV)and undergo heat treatment for reinforcement.
Regarding rust resistance:
·Black Chains:Usually coated with anti_rust oil,making them suitable for indoor use or short-term outdoor applications.
·Galvanized Chains:Surface-treated with electro-galvanizing or hot-dipgalvanizing,ideal for humid environmentsor long-term outdoor use.
·Stainless Steel:Designed for food processing or highly corrosive chemical environments.

Q How do I choose the right chain or scraper model for my working conditions?
A Selection primarily depends on your load weight, operating speed, and working environment (such as temperature and corrosiveness). For instance, mining conveyance typically requires high-strength mining round link chains (e.g., Grade C, G80), whereas the food industry mandates stainless steel materials. We recommend providing detailed operating parameters (e.g., conveying capacity in tons/hour), and our engineers will recommend the most suitable model for you.
