Recently, at the construction frontlines of multiple national key transportation projects, Sunward's SWDM series extended-range rotary drilling rigs have demonstrated the dual advantages of energy savings and efficiency through actual on-site operating data, safeguarding project construction.

At the Weifang-Rongcheng Expressway reconstruction and expansion project in Pingdu, Qingdao, Shandong, the pile foundation construction is located in slightly weathered granite strata, with a pile diameter of 1.2 meters and a hole depth of 15 to 17 meters. The SWDM520E extended-range rotary drilling rig operating on site in extended-range mode consumes 10 liters of fuel per hour, far lower than fuel-powered rotary drilling rigs of the same class, and has been recognized by the customer.
