威猛公司又在其NAVIGATOR系列水平定向钻进系列钻机中添加了一种新的钻机D10 0× 2 0。该钻机具有许多以前钻机所拥有的特点 ,例如自D33× 4 4钻机起首先采用的齿轮齿条结构。D10 0× 12 0钻机的扭矩为 16 2 70N·m ,回拖力为 4 5 35 9kg。这一组合使得处理大口径管线变得更为
WITTMANN added a new drill, D10 0 × 20, to its NAVIGATOR series of horizontal directional drilling rigs. The rig features many of the features of previous rigs, such as the rack-and-pinion arrangement first used since the D33x4 4 rig. The torque of D10 0 × 12 0 drilling rig is 16 2 70N · m, and the back drag is 4 5 35 9kg. This combination makes the handling of large diameter pipelines even more impressive
