徐工QY25K5D 25吨起重机
广泛用于城市更新，交通，港口，桥梁，油田，工矿企业等的起重作业和安装工作。
性能特征:
1.汽车起重机QY25K5D采用U形截面吊臂，深宽比小，承载能力强，变形小，抗弯能力强，起重能力强。主吊杆长度为10.6m--41.0m，性能中延动臂和完全延动臂也比较优越。
2.插入式动臂头有效增加动臂连接长度，减少动臂变形。
3.汽车起重机QY25K5D配备了嵌入式滑块，扩大了接触面积，降低了动臂的接触应力。
4.汽车起重机QY25K5D配备9种变速器，具有优越的行驶和等级能力。最大等级能力40%，最大行程速度为90km/h。
5.满足速度要求，有效降低能耗和系统热量。
