近日,北京三一重机自主研发的SR630RC8型旋挖钻机成功交付用户。目前,该旋挖钻机已经在深圳开工,助力深圳城市建设。2011年,三一研曾成功研制出SR 460型旋挖钻机,其最大钻孔直径达3.5 m,最大钻孔深度达120 m。SR630RC8型旋挖钻机打破了这一纪录,其最大钻孔直径为4.5 m,最大钻孔深度为140 m,最大输出转矩为630 k N·m,成为当前亚洲
Recently, SR-330RC8 rotary drilling rig researched and developed independently by Beijing Sany Heavy Machinery has been successfully delivered to users. At present, the rotary drilling rig has started in Shenzhen, helping Shenzhen city construction. In 2011, Trinity Research successfully developed the SR 460 rotary drilling rig with a maximum drilling diameter of 3.5 m and a maximum drilling depth of 120 m. SR630RC8 rotary drilling rig to break this record, the maximum drilling diameter of 4.5 m, the maximum drilling depth of 140 m, the maximum output torque of 630 kN · m, as the current Asia
