The invention provides a moment control system and method for a lorry-mounted crane. According to the method, the real-time moment information of a lazy arm is determined through obtaining the stretching state and the acting force state of the lazy arm of the lorry-mounted crane, and the hoisting state information of a target object and the rated moment information of the lazy arm serve as the basis; and the actual magnitude of the real-time moment or different parameters of the real-time moment are adjusted so that the target object can be lifted uniformly and stably in the lifting operationprocess of the target object, and the lifting efficiency and the lifting stability of the target object are improved.

    本发明提供了随车起重机的力矩控制系统与控制方法,其通过获取随车起重机的吊臂伸展状态和作用力状态来确定吊臂的实时力矩信息,并以目标物的起重状态信息和吊臂的额定力矩信息为依据,调整实时力矩的实际大小或者实时力矩的不同参数,以此保证在对目标物进行起重操作过程中能够使得目标物均匀地和平稳地升降,从而改善对目标物的起重效率和起重平稳性。
