Abstract

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.

Description

technical field [0001] The invention relates to the technical field of truck-mounted cranes, in particular to a moment control system and method of the truck-mounted crane. Background technique [0002] With the development of infrastructure, truck-mounted cranes are widely used in engineering construction on different occasions. Truck-mounted cranes can move to different locations to lift corresponding objects according to actual needs. During the lifting process, the truck-mounted crane relies on the corresponding moment of the boom to lift and lower the target object, and the magnitude of the moment will directly affect the lifting speed and stability of the target object, and the corresponding torque of the boom arm The moment depends on the extended state of the boom and the state of the lifting force. The truck-mounted cranes in the prior art can only apply a constant moment to the target object through the boom, which cannot adaptively adjust and control the real-tim...
