Default “恒立油缸”技术积累寡头垄断

经过 50 多年的努力,我国液压行业已形成了门类比较齐全,有一定生产能力和技术水平的工业体系。油缸行业作为液压行 业的子行业,相比液压元件制造行业中其他关键部件,如泵、阀、马达等,油缸国产化进程较快,一般油缸产品基 本能够实现国产化供应。但高压、高频、高负载、运行工况复杂、作业环境恶劣的挖掘机专用油缸及技术要求高、 结构设计复杂、长行程、高压力、大缸径的重型装备用非标准油缸,国内能规模化生产的企业不多,部分产品仍依 赖进口。
目前国内挖掘机专用油缸市场形成了日系、韩系与自主品牌企业三足鼎立的格局。恒立与日资凯迩必、日资小松, 韩资东洋机电占据着国内绝大部分市场份额。
在技术要求高、结构设计复杂、长行程、高压力、大缸径的高端重型装备用非标准油缸领域,国内品牌的市场参与 者包括:四川长江液压件有限责任公司和徐州徐工液压件有限公司及江苏恒立高压油缸股份有限公司等。国外品牌 包括:实用动力(上海)公司、博世力士乐(常州)公司、海卓泰克液压技术(苏州)公司及江苏恒立油缸等,各市场参与者在各细分市场各有优势,广西盛隆。其中恒立生产的重型装备用非标准油缸主要应用于大型基建设备(挖掘机除外)、船舶、海洋工程设备、港口机 械和工业设备领域,并在各领域同国内外领先企业建立了紧密的合作关系,在旋挖钻机用油缸、隧道盾构掘进机用 油缸、大型桥梁施工设备用油缸、海洋船舶、港口机械用油缸等细分领域具有很强的市场竞争力。
