The invention relates to the technical field of cranes, in particular to a grab bucket variable crane. The grab bucket variable crane comprises a crane grab bucket handle, wherein a pin shaft throughopening is formed in the top of the crane grab bucket handle, a foot head is arranged at the bottom end of the crane grab bucket handle, a fixed frame is arranged on the surface of the crane grab bucket handle, a driving motor is arranged in the fixed frame, a shaft body of the driving motor penetrates through the fixed frame and then is connected with a driving belt wheel, a transmission belt iswound around the surface of the driving belt wheel and penetrates through a belt penetrating opening, and the belt penetrating opening is formed in the surface of the crane grab bucket handle. The grab bucket variable crane has the advantages that a control groove is formed in the surface of the crane grab bucket handle, and an auxiliary structure for improving grab stability is arranged in the control groove in a protruding mode, so that an object is prevented from sliding off when grabbed by a plurality of crane grab bucket handles; and the control groove is located in the middle of the crane grab bucket handle, so that the contact area between the structure in the control groove and the grabbed object is sufficient.
本发明涉及起重机技术领域,具体为一种抓斗可变式起重机,包括起重机抓斗柄,起重机抓斗柄的顶部开设有销轴通口,起重机抓斗柄的底端设置有脚头,起重机抓斗柄的表面设置有固定架,固定架的内部设置有驱动电机,驱动电机的轴体贯穿固定架后连接有驱动带轮,驱动带轮的表面绕过有传动带,传动带穿过穿带口,穿带口开设在起重机抓斗柄的表面;有益效果为:本发明提出的抓斗可变式起重机抓斗柄表面开设操控槽,操控槽内部突出设置有增加抓取稳定性的辅助结构,如此避免物体在多个起重机抓斗柄抓取时滑落,操控槽处于起重机抓斗柄的中部位置,因此操控槽内部的结构与所抓取的问题接触面积充足。
