This solution addresses the problem that most existing small cranes are equipped with only a single hook 112, which is insufficient when lifting multiple small goods. Currently, the lifting hooks 112 can only be operated one by one, which not only consumes a lot of time and reduces work efficiency, but also increases the cumbersomeness and safety hazards of operation during multiple lifting operations. Understandably, the aforementioned solution allows the operator to start the hydraulic press 103 via the control button 116 on the control console 114 during lifting operations. The hydraulic press 103 then provides power, and according to the operational requirements, by controlling the rotation of the rotating disc 104, it can drive the lifting column 105, the telescopic column 107 above it, the hooks 112, and other components to rotate together. Adjust to a suitable working direction; control the extension and retraction of the lifting column 105 to change the height of the hook 112 to a position corresponding to the height of the goods; control the extension and retraction of the telescopic column 107 to adjust the horizontal position of the hook 112, moving it directly above the goods. Then, by controlling the lowering of the steel cable 109, the double hooks 112 on the extension frame 111 below the sub-lifting plate 110 are lowered to the goods. The operator hangs the goods on the two hooks 112 respectively. After hanging the goods, the steel cable 109 is retracted again by controlling the control button 116. After the goods are lifted, the state of the turntable 104, the lifting column 105, and the telescopic column 107 can be adjusted to transport the goods to the designated location. Finally, the steel cable 109 is lowered to complete the unloading of the goods. During the entire operation, the operator can observe the crane's operating parameters in real time through the display screen 115 on the control console 114 to ensure safe and stable operation. The design of the double hooks 112 allows the crane to lift two small goods at the same time without having to operate them one by one, which greatly improves work efficiency and reduces the cumbersome operation and safety hazards caused by multiple lifting operations.

[0020] In this specific embodiment, the hydraulic press 103 is detachably connected to the base 101 and is located on the upper side of the base 101; the rotating disk 104 is detachably connected to the hydraulic press 103 and is located at the upper center of the hydraulic press 103; the lifting column 105 is rotatably connected to the rotating disk 104 and is located at the upper center of the rotating disk 104, and the lifting column 105 and the rotating disk 104 are arranged perpendicularly; the connecting block 106 is detachably connected to the lifting column 105 and is located above the lifting column 105; the telescopic column 107 is detachably connected to the connecting block 106 and is located on one side of the connecting block 106, and the telescopic column 107 and the connecting block 106 are arranged perpendicularly.

According to operational requirements, by controlling the rotation of the rotating disc 104, the lifting column 105, the telescopic column 107 above it, the hook 112, and other components can be rotated together to adjust to a suitable working direction. Controlling the extension and retraction of the lifting column 105 changes the height of the hook 112, bringing it to a position corresponding to the cargo. Controlling the extension and retraction of the telescopic column 107 adjusts the horizontal position of the hook 112, moving it directly above the cargo. Subsequently, by controlling the lowering of the steel cable 109, the double... The hooks 112 descend to the cargo location, and the operator hangs the cargo on both hooks 112. After hanging the cargo, the operator controls the steel cable 109 to retract via the control button 116, lifting the cargo. Then, by adjusting the states of the turntable 104, the lifting column 105, and the telescopic column 107, the cargo can be transported to the designated location.
