It should be noted that, the base 10 includes the first base body 110 and the second base body 120, and the weighing sensor 20 is disposed between the first base body 110 and the second base body 120, and then the cable wire on the cable reel 50 disposed on the first base body 110 and the steel wire of the steel wire reel 40 disposed on the first base body 110 are respectively connected to the clamp, that is, the cable wire is connected to the electrical socket disposed on the clamp, and the steel wire is fixedly connected to the connection end disposed on the clamp, and then the crane can control the opening and closing of the clamp through the cable, and then control the amount of the clamp for grabbing the goods, and then the overall weight of the second base body 120 can be increased, so that the weighing sensor 20 disposed between the first base body 110 and the second base body 120 can measure the weight of the goods grabbed on the clamp. Therefore, the weighing sensor 20 is disposed between the first base body 110 and the second base body 120, so that the amount of the goods grabbed by the clamp can be controlled, and the wire reel 40 and the cable reel 50 are separately arranged, and further, the length of the steel wire wound on the wire reel 40 and the length of the cable wound on the cable reel 50 can be increased, so that the control of the clamp with different heights is increased, and the lifting range of the crane is enlarged.

The first base 110 is provided with a first through hole 1110, and the second base 120 is provided with a second through hole 1210 corresponding to the first through hole 1110; the wire on the wire reel 40 and the cable on the cable reel 50 are connected to the clamp through the first through hole 1110 and the second through hole 1210. Since the guide rail is provided above the clamps, the wires and cables extending downward from the wire reel 40 and the cable reel 50 are connected to the clamps. The first through hole 1110 and the second through hole 1210 are provided so that the wire rope and the cable can directly extend downwards from the wire reel 40 and the cable reel 50 to the clamp, and the effective use length of the wire rope and the cable is increased.
