The invention provides a steering monitoring method and system of a multi-shaft steering crane and the crane, and solves the technical problem that in the prior art, different steering assistance cannot be provided for all steering axles so as to protect a steering rod system. First-moment axle load state information and second-moment axle load state information of a steering axle are obtained, namely, the axle load state information of the steering axle is obtained in real time, the axle load state of the steering axle is obtained according to the first-moment axle load state information and the second-moment axle load state information, control information is generated, and the control information is used for controlling the opening degree of the valve port of a pressure reducing valve. The oil pressure in the oil way of the steering axle is changed, so that the power-assisted steering of the steering axle is changed, different power-assisted steering is provided for the steering axle in the steering process of the crane, redundant power-assisted steering is prevented from being transmitted to a steering rod system, and the purpose of protecting the steering rod system is achieved.

    本申请提供了一种多轴转向起重机的转向监控方法、系统及起重机,解决了现有技术中不能为各转向桥提供不同的转向助力,以实现保护转向杆系的技术问题。通过获取转向桥的第一时刻轴重状态信息、第二时刻轴重状态信息,即实时获取转向桥的轴重状态信息,根据第一时刻轴重状态信息、第二时刻轴重状态信息来获知转向桥的轴重状态,生成控制信息,该控制信息用于控制减压阀的阀口开度,以使转向桥油路中的油压进行改变,从而改变转向桥的转向助力,以使起重机在转向过程中,为转向桥提供不同的转向助力,防止将多余的转向助力传递给转向杆系,进而实现保护转向杆系的目的。
