Product delivery | A large number of high-strength brackets were delivered to the National Energy Mengxi Qipanjing Coal Mine

In May this year, 221 Sany heavy-duty high-strength brackets ZY8000/20/42D were successfully delivered to Guoneng Mengxi Qipanjing Coal Mine.

In 2009, Qipanjing Coal Mine purchased 150 sets of Sany Heavy Equipment ZY6000/20/40 hydraulic supports and 1180 seriesShearersOne unit, which has been continuously used in the underground for 12 years, has good use effect, superior quality of structural parts, and low failure rate, and will be lifted and retired in 2021. Based on the trust and cooperation with Sany for many years, coupled with the demand for higher quality and higher standards of products in this procurement, the customer finally chose Sany Heavy High-strength Bracket ZY8000/20/42D after preliminary technical exchanges.

Through R&D, innovation and test platform and high-strength plate welding technology, combined with the comprehensive advantages of high-strength material supply, Sany Heavy Equipment applies TOP-DOWN parametric design and digital virtual verification to carry out refined design of hydraulic support, so as to ensure the strength and durability of the hydraulic support while making it lightweight.
