英国马鲁(MARLOW)钻探有限服务公司最近推出一种DD3型新钻机。DD3型钻机具有迁移方便,多功能和回转,给进,加压及提升都采用先进的全液压传动等特点。该机适用于金刚石岩心钻进(0—1750转/分),潜孔锤钻进,牙轮钻进或连续螺旋钻进(0—233转/分)。钻机的动力头上有一高低速变速手柄能迅速地将钻进覆盖层时的转速变换为钻进基岩时的转速。在施工现场搬迁较困难或用直升飞机吊运不可能的情况下,在十分钟内,钻机可解体成两个人就能搬迁的组件。钻机可解体成
MARLOW Drilling Services Limited recently launched a new DD3 drilling rig. The DD3 drilling rig has the advantages of convenient migration, multi-function and rotation, advanced full hydraulic transmission for feeding, pressurizing and lifting. This machine is suitable for diamond core drilling (0-1750 rev / min), DTH hammer drill, cone drilling or continuous spiral drilling (0-233 rpm). A high-low-speed shift handle on the power head of the rig can quickly change the rotational speed when drilling into the cover to the rotational speed when drilling into the bedrock. It is difficult to relocate at the construction site or it is impossible to lift by a helicopter. Within ten minutes, the rig can be disassembled into two components that can be relocated. The rig can be disassembled into
