瑞典克瑞留斯公司设计和制造了为钻进3000公尺深度的B-35型钻探机（图1）。该机的优点是钻头的转速范围大，重量轻便于运输。钻探机械与架子一同安装在钻塔架子的金属底盘上。在图2中表示钻机的详细装置图。钻机可以与架子和传动装置一起放在普通12吨的载重汽车上运输。
The Swedish Reuilders has designed and manufactured the B-35 drilling rig for drilling depths up to 3,000 meters (Figure 1). The advantage of this machine is the speed range of the drill bit, light weight and easy to transport. Drilling machinery and shelves are installed on the metal chassis of the rig tower rack. A detailed installation diagram of the drilling machine is shown in FIG. 2. The rig can be transported with shelves and gear on a typical 12-ton truck.
