2013年4月3日,在青荣高铁烟台段的施工现场,一台福田雷沃FR630D型旋挖钻经过2h的施工作业,从地下50m处的片岩层中钻出一块直径为1.1m、长1.6m的大理岩。此块岩石体积较大,在施工中比较罕见。雷沃FR630D型旋挖钻机采用的是3组马达减速器,动力头多挡控制,可选不同施工模式,并且可针对不同工况设计动力组合系统,输出扭矩大,工程适应性强,匹配度高,入岩能力强劲,可实现复杂地层各种地质24h施工。双泵合流的应用使主卷扬提升下放更快,效率提高22.8%。匹配卡特
On April 3, 2013, at the construction site of Yantai Section of Qingrong High Speed Rail, a Fukuda Revo FR630D rotary drill was drilled for 2 hours from the schist layer at a depth of 50m to drill a diameter of 1.1m long 1.6m marble. This rock is large and relatively rare in construction. Lovol FR630D Rotary Drilling Rig is used in three sets of motor reducer, power head multi-block control, optional different construction modes, and can be designed for different power system combinations, output torque, engineering adaptability, matching High, rock into the strong ability to achieve complex geological formations 24h geological construction. The application of the dual-pump confluence makes the main hoist lift and release faster and the efficiency increased by 22.8%. Match Carter
