The invention relates to the field of equipment control, and discloses a suspension arm control method and device, a crane and a computer readable storage medium. The suspension arm control method is applied to the crane comprising a suspension arm and superlift equipment, and comprises the following steps: controlling the suspension arm to stretch in response to a received suspension arm stretching request; determining a target rope length value of the superlift equipment according to the real-time length of the suspension arm and the superlift arm length of the superlift equipment; and based on the target rope length value and the real-time rope length of the super-lifting equipment, the stretching speed of the suspension arm is adjusted, and the winding speed of the super-lifting equipment during rope winding and unwinding is adjusted. The hoisting speed of the super-lifting equipment during rope winding and unwinding is actively adjusted on the basis of the target rope length value, the situation that the lifting arm is reversely warped or the deflection is too large in the telescopic process of the lifting arm is avoided, and the super-lifting equipment can be suitable for the scene with the requirement for high tension of the super-long lifting arm.
本申请涉及设备控制领域,公开了一种吊臂控制方法、装置、起重机及计算机可读存储介质。吊臂控制方法应用于包括吊臂和超起设备的起重机,包括:响应接收到的吊臂伸缩请求,控制所述吊臂进行伸缩;根据所述吊臂的实时长度和所述超起设备的超起臂长度,确定所述超起设备的目标绳长取值;基于所述目标绳长取值和所述超起设备的实时绳长,调整所述吊臂的伸缩速度,并调整所述超起设备收放绳时的卷扬速度。基于目标绳长取值主动调节超起设备收放绳时的卷扬速度,吊臂伸缩过程中不会出现吊臂反翘或挠度过大的情况,使得超起设备能够适用于超长吊臂的高拉力需求的场景。
