SWH hydraulic hammer is a kind of demolition device which converts hydraulic nergy into impact energy. Based on the achievement in hydraulic rock drilling studying, combined with world-ranged advanced technology, Prof, He Qing-hua, director of Intelligent Machinery R&D Institute of Central South University, lead a team to develop SWH hydraulic hammer successfully. Mounted on excavator, backhoe, loader, or other hydraulic equipment, SWH hydraulic hammer features with the high efficiency, low operating cost, and high reliability, has a wide range of applications in the demolition engineering of construction, mining, metallurgy, and hydropower, etc.
