The invention discloses a crane axle load balancing device and balancing method.The crane axle load balancing device is arranged between suspension oil cylinders of different axles, is provided with a port A and a port B which are connected with the different suspension oil cylinders and a port P connected with an energy accumulator, and is configured in the mode that no matter hydraulic oil flows from the port P to the port A/B or flows back from the port A/B to the port P, the hydraulic oil flows back from the port A/B to the port P; the port A and the port B have fixed pressure difference; according to the axle load balancing device of the crane, the pressures of the suspension oil cylinders of different axles can be inconsistent, so that the axle load difference caused by the self-weight difference of the axles is compensated, and the axle loads of the axles are consistent. Axle load balance of the axle can be achieved, and the crane performance is improved.
本发明公开了一种起重机轴荷平衡装置及平衡方法,所述的起重机轴荷平衡装置设置在不同车轴的悬架油缸之间,具有分别连接不同悬架油缸的A口和B口,以及连接蓄能器的P口,并被配置为无论液压油是从P口向A/B口流动,还是从A/B口向P口回流,A口和B口均有固定压差;所述的起重机轴荷平衡装置能够使不同车轴的悬架油缸的压力不一致,以补偿因车轴自重差异导致的轴荷差异,使车轴轴荷一致。本发明能够实现车轴轴荷平衡,提升起重机性能。
