在阿特拉斯科·普柯Craelius公司总部,瑞典首都斯德哥尔摩附近Marsta的入口处,长期摆放着该公司制造的第一台蒸汽驱动钻机(图1),以时刻提醒公司的创新意识。也许仅有少数人知道这家从事金刚石取芯钻机制造的小公司是在100多年前由Per Anton Craelius先生创立的,如今已成为一家勘探钻进设备的主要供应商。 At the entrance of Atlas Copco’s Craelius headquarters in Marsta, near the Swedish capital, Stockholm, the company’s first steam-driven rig (Figure 1) has long been on display to remind the company of its innovation. Perhaps only a few people know that this small company engaged in the manufacture of diamond core drilling rigs was founded more than 100 years ago by Mr. Per Anton Craelius and is now a major supplier of drilling equipment for exploration.
