The invention relates to the technical field of hoisting equipment, and discloses a grab bucket type crane. The grab bucket type crane comprises a control box, wherein the control box is connected with a travelling crane through a winch structure, two hoppers are arranged below the control box, the two hoppers are hinged to inner connecting rods and outer connecting rods, and a lower hydraulic cylinder and an upper hydraulic cylinder are arranged at the two ends of the control box. According to the grab bucket type crane, when the grab bucket type crane is in a closed state, connecting pointsof the inner connecting rods and the hoppers serve as fulcrums, the closing capacity of the grab bucket type crane is enhanced, the two hoppers can be separated and adjusted in angle, can be independently used and hold up powdery or liquid objects, the use range of the crane is widened, and larger opening can be achieved in a separated mode; and the crane can move horizontally and can shovel tiledmaterials, the capacity of shoveling the materials in a single state is improved, the material shoveling direction and angle can be automatically adjusted when the crane encounters hard material blockage, the crane moves in the labor-saving direction , and abrasion of a cutting edge and a shaft sleeve is reduced.

    本发明涉及起重设备技术领域,且公开了一种抓斗式起重机,包括控制箱,所述控制箱通过卷扬结构于行车连接,所述控制箱的下方设有两个料斗,两个所述料斗均铰接有内连杆和外连杆,所述控制箱的两端设有下液压缸和上液压缸。该抓斗式起重机,在闭合状态时,以内连杆与料斗的连接点为支点,增强了其闭合能力,其次,由于两个料斗可分离且角度可调整,可以独立使用,将粉末状或液态的物体兜起,增加了该起重机的使用范围,还有,可分离实现更大的张口,并且可以水平移动,可以将平铺的物料铲起,提高了单次状态物料的能力,并且在遇见较硬的物料阻碍时,可以自动调整铲料方向和角度,沿着较为省力的方向移动,降低了刃口和轴套的磨损。
