不管是技术突破还是民族情结,“国产最大吨位自制专用底盘旋挖钻机”的帽子已然戴到了徐工X R460D型旋挖钻机头上,那么于情于理这款设备都值得“围观”。毫无疑问,这是一款有故事的设备。国产42t·m以上旋挖钻机一般采用可靠的卡特彼勒挖掘机底盘,整机售价在1500万元左右,而外资42t·m以上机型价位高达2500万元。关键技术与国产配件质量的桎梏,曾一度成为国产制造商地隐痛,而徐工XR460D型旋挖钻机能够走出樊笼另辟蹊径,这款设备算得上是大吨位旋挖钻机的逃生之作。
Whether it is a technological breakthrough or a national complex, “Domestic maximum tonnage made special chassis rotary drilling rig ” hat has been worn on the XCMG X R460D type rotary drilling rig head, then in love this device is worth “onlookers ”. There is no doubt that this is a story of the equipment. Domestic more than 42t · m rotary drilling rig Caterpillar excavator generally reliable chassis, the whole price of about 15 million yuan, while the foreign 42t · m models priced above 25 million yuan. The key technology and the quality of domestic parts 桎 梏, once a domestic manufacturer of pain, and Xugong XR460D-type rotary drilling rig out of the cage another way, this equipment can be regarded as a large-tonnage rotary drilling rig for the escape.
