▣Our company has a strict quality control system during the manufacturing and commissinning. For example, before we use each hydraulic cylinder and suspensioin, Supro Trailer make oil pressure testing to make sure each of it is qualified! So our company provides superior quality of the heavy transporter to our clients! Our company is the unique factory in China who has experience on European and USA market.

▣About the self propelled modular trailer, it has rare manufacturers except for European companies who is able to design and produce it. If you are going to buy it from European companies, the price is very expensive and also the delivery time is too long. Never mind the customized self propelled traveling system, the price is flying is the sky. Nobody in developing country is able to afford it, because the profits of crane projection is cheap in there. The price of Supro customized traveling system has a huge advantage than European one! More important is that Supro Trailer is able to provide stable performance and good quality traveling system to your machine! You can set your heart free on cooperation with Supro Trailer!
