尽管处于市场调整期,但2012年,企业在优化产能、提高产品品质等方面下足了功夫,涌现出一批高品质、高水平的产品。技术成果得到认可的同时,龙头企业主攻高端,大型高难度工程机械产品层出不穷。大型高难度产品的研制似乎已经形成竞赛趋势,在buama China 2012展会上便可见一斑,中联重科展出101m臂架混凝土泵车、2000t级全地面起重机、300t液压挖掘机等;徐工展出D E400型电传动自卸车、5000t·m力矩的全地面起重机等设备;三一重工展出3600t级履带式起重机。由中国品牌工程机械企业保持的世界纪录越来越多并不断再创新高。据悉,徐工自主研发制造的全球最大4000t级履带起重机挑战极限,数次成功完成4500t的超载实验。大型高端工程机械层出不穷,对工程机械制造商和工程机械用户意味着什么?设备的真正价值能否体现?其背后有怎样的深层次意义?本期特稿,《工程机械与维修》邀请业内3位意见人士,讲述他们对此的理解。
Despite the market adjustment period, in 2012, the enterprises made sufficient efforts to optimize production capacity and improve product quality, and a number of high-quality and high-quality products emerged. While technical achievements are recognized, the leading enterprises mainly focus on the high-end and large-scale difficult construction machinery products. The development of large and difficult products seems to have formed a competition trend, which can be seen at the buama China 2012 exhibition. Zoomlion exhibited 101m boom concrete pump truck, 2000t all-terrain crane, 300t hydraulic excavator and so on. D E400 electric drive dump truck, 5000t · m torque all-terrain cranes and other equipment; Sany Heavy Industry exhibited 3600t-class crawler cranes. The world record maintained by Chinese brand construction machinery enterprises has been continuously increasing to a new high. It is reported that XCMG independent research and manufacture of the world’s largest 4000t crawler crane challenge limit, successfully completed several 4500t overload test. Large-scale high-end engineering machinery after another, what does it mean to the construction machinery manufacturers and construction machinery users? Can the true value of the equipment be reflected? What is the deep meaning behind it? This special feature, “Construction Machinery and Maintenance,” invites the industry 3 Some commentators, about their understanding of this.
