Default 恒立油缸:国内挖掘机油缸生产寡头垄断企业

油缸属于液压系统关键零部件,其发展历程基本与液压行业发展一致,恒立油缸。发展初期,国内油缸生产企业普遍工艺落后,油缸产品质量不高,寿命短、密封性能差、易泄漏,研发能力薄弱 。经过多年的技术攻关与积累,目前国内仅有江苏恒立生产加工设备和加工工艺实现与国际同步,这为高压油缸国 产化迈出了坚实的一步。
随着我国经济的快速发展,基础设施和基础工业建设保持稳步增长,加之国家拉动内需、增加基础设施投资力度等 因素影响,我国装备制造行业呈现高速增长态势,其中挖掘机、旋挖钻机、大型桥梁施工设备、隧道盾构掘进机等 工程机械,船舶、海洋工程、港口机械、冶金设备、风力发电设备等行业都直接受益。基于此,作为核心部件的油 缸,市场需求保持高速增长。
江苏恒立高压油缸股份有限公司作为国内唯一自主挖掘机专用油缸制造品牌,专注于高端挖掘机专用高压油缸产品 ,国内市场供不应求,形成了寡头垄断的格局。
