The invention discloses a control method, device and equipment for a crane variable-amplitude operation system, and the method comprises the steps: obtaining system parameters of a crane, and predicting whether an electric control handle is adjusted within a preset opening range or not according to the system parameters; when the electric control handle is adjusted within the preset opening range, target pilot current is obtained through angular velocity feedback of the rising and falling amplitude of the big arm of the crane; and controlling a main valve of the crane according to the target pilot current, and executing corresponding amplitude starting or amplitude falling actions. According to the technical scheme, when a user controls the handle to conduct small-opening-degree operation, the phenomena of impact, shaking and the like can be reduced, and the sensitivity and the fitting degree of starting amplitude and falling amplitude of the crane are improved.

    本发明公开了一种起重机变幅操作系统的控制方法、装置和设备,其中方法包括:获取起重机的系统参数,根据系统参数预测电控手柄是否在预设开度范围内调整;当电控手柄在预设开度范围内调整时,通过起重机大臂起落幅的角速度反馈得到目标先导电流;按照目标先导电流控制起重机主阀,执行相应的起幅或落幅动作。本发明提供的技术方案,能够在用户控制手柄进行小开度操作时,减小冲击和抖动等现象,提高起重机起幅与落幅的灵敏度和贴合度。
