徐重QUY300型履带式起重机攻克了大吨位履带式起重机众多关键核心技术,集中了液压系统逻辑集成控制装置、液压回路转换阀、分体式转台和液压控制卷扬棘轮锁止装置等徐重自有的10余项国家专利,是国内第一台完全拥有自主知识产权的300t级履带式起重机,关键动力元件、传动元件、液压元件均选自国际著名厂家。该车接地比压小,转弯半径小,爬坡能力强,最大爬坡度可达30%,可以在松软及崎岖不平的地面上行驶。可广泛应用在市政工程、工矿企业、码头、机场、水利水电以及石化等领域的工程建设中。
Xu heavy QUY300 Crawler Crane overcome many of the core technology of large tonnage crawler cranes, centralized hydraulic system logic integrated control device, the hydraulic circuit switching valve, split turntable and hydraulic control winch ratchet locking device Xu heavy own Of the more than 10 national patents, is the first complete with independent intellectual property rights of 300t crawler cranes, the key power components, transmission components, hydraulic components are selected from well-known international manufacturers. The car grounding than the small pressure, turning a small radius, climbing ability, the maximum climb up to 30%, can be soft and bumpy ground driving. Can be widely used in municipal engineering, industrial and mining enterprises, docks, airports, water conservancy and hydropower and petrochemical projects in areas such as construction.
