How should we stabilize the hook when using a crane? below Huai'an Crane Rental Company Let's tell you how to do it!

1. Stabilizing hook swinging back and forth

When the lifting object sways in the forward and backward directions, it sways back and forth along the trolley track. Stabilizing this swing method can start the trolley to follow in the swing direction of the lifting object. If the car is followed in a timely and appropriate manner, the swing can be eliminated once. If the rocking is not completely eliminated after a car following, you can follow the car back once according to the above method until the rocking is completely eliminated.

2. Left and right swinging hook

When the lifting object sways from side to side, it sways back and forth along the crane track. The way to stabilize this swing is to start the cart to follow the cart along the swing direction of the hoisted object. If a car following does not completely eliminate the swing, you can follow back once. If the following speed and distance are appropriate, the lifting object can be stabilized after 1~2 times of following.  

In the lifting process of the crane, the shaking hook is often encountered. The shaking hook shows that the lifting object swings back and forth in a large range, and the lifting hook shakes several times within a swing angle of the lifting object at a small angle. The reason for shaking is that the length of wire rope for lifting objects is different; The center of gravity of the lifting object is off center; The hook is not aligned with the center of gravity of the lifting object during operation.

It is difficult to stabilize the shaking hook. The method to stabilize the shaking hook is: when the lifting object swings forward slowly and significantly, and the hook shakes rapidly at a small angle, when the direction of the shaking hook is the same as that of the large swing of the lifting object, follow the hook quickly, that is, quickly push the controller handle back to zero.

When the lifting object swings back, when the hook shakes back at a small angle, quickly follow the hook back and quickly push the controller handle back to the zero position. In this way, every time you follow the hook back and forth, the shaking angle will be reduced a lot. If you master the above following operation sequence skillfully and operate properly, you can generally stabilize the hook only by 2-3 times.
