DWX(piston suspend)suspended hydraulic prop was a new generation of hydraulic prop products jointly developed by China University Mining and technology and our company, which gets 12 national patents(97107063.6 etc.). The product had passed the ability testing of National Mine safety equipments Testing Center in September, 2002 and got the Certification of Mine Safety. At the same time, the product was recommended as the emphasized project of national scientific and technological program to be extended by Ministry of Science and Technology during the 10th five-year period in April 2003.
DWX suspended hydraulic prop is a new generation of hydraulic prop that is the assort equipments of machinery mine work section and the security equipments of mine, which is fit for the support and protection of mine coping on work sections. Because of its strong sustentation capability, anti-deflection capability, and large working range, it can be widely used for the support and protection of work sections in various coal layers. Therefore, the miners called the prop"the backbone of life" as well as"the best prop in the world".
