Truck Crane A4-3 The truck crane, with spacious cab and compact decoration, adopts full slewing system, 5-section telescopic boom sections, hydraulic proportional control system and self-made full-width special purpose chassis with three axles. 6× 4 drive provides the crane with good driving performance and flexible steering. The engine complies with the National Stage III emission standard. The system with latest load feedback hydraulic operated proportional directional control valve and quadruple gear pump, and the safety devices fitted in hydraulic system, such as relief valve, balance valve, hydraulic lock and brake valve etc., prevents the oil line from overloading and the accidents caused by oil pipe breakage and makes full use of the working capacity of each actuating mechanism. Thus the reliability and safety of the crane are increased. The safety devices such as load moment limiter, and the complete lighting system equipped in the crane ensure your safety during operation and are convenient for night work.Item Value Remarks Working performance Max. rated lifting capacity kg 25000 Max. load moment of basic boom kN.m 980 Max. load moment of max. boom length kN.m 494 Max. lifting height of basic boom m 11.0 Max. lifting height of boom m 39 Deformation of the boom is not taken into consideration.
