XCMG QY25K-II Truck Crane
We are constantly devoting ourselves to the development of the new cranes by applying the latest techniques. The new products will have strong functions and be more adaptive to the customers. QY25K truck crane was developed by our company in 2000. Through constant upgrade, the travel and working performance are greatly improved. The chassis is three-axle which has strong power and cross-country capacity. The jib is optimized octagon section, which has excellent lifting capacity. The control system adopts hydraulic proportional (mechanical) control technique.
