Date of issue: 2022-01-17 Author: Click:

It is a common phenomenon that the truck crane swings back and forth due to inertia. I believe that all "old drivers" will feel that there are some potential safety hazards, and that the hook swinging back and forth during driving will also cause some trouble for the vehicle. below Huai'an Crane Rental Company Introduce some operation skills about the stable hook.

1. Swing the hook back and forth: That is, swing along the trolley track, and the trolley can be started to follow 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 cannot be eliminated once, you can follow the car back once according to the above method until the rocking is completely eliminated.

2. Swing the hook from left to right: That is, swing along the crane track, and start the crane to follow along the swing direction of the lifting object. When the lifting object is in a large swing range, stop following, so that the weight is in a vertical position. If rocking is eliminated, follow the car once according to the above method. Generally, rocking can be eliminated once or twice.

3. Lifting hook stabilization: When the gear object is heavier and the vehicle is lifted faster, the object will lag behind the vehicle body. At this time, the cart or trolley should be returned to zero position in time. When the hoisted object swings forward beyond the middle vertical line of the car body, the forward car following should be started immediately to run at the same speed to eliminate the swing.

4. Stabilizing hook in situ and running

(1) If the cart or trolley arrives at the parking place, but the lifting object does not stop due to the high speed, but swings forward, the lifting object cannot be put down immediately. Start the car body to follow the car forward to half of the larger swing of the lifting object and wait for the lifting object to swing back. When the hoisted object swings back, start the vehicle body again to follow the vehicle. Generally, the hoisted object can be stably parked at the parking position once or twice.

(2) When the hoisted object swings forward during operation, speed up to make the operating mechanism follow the swing of the hoisted object. When the lifted object swings backward, it should slow down to keep up with the running speed of the car body. So as to reduce the swing back of the hoisted object. Through several times of repeated acceleration, deceleration and car following, the lifting object and running mechanism can operate smoothly

5、 Stabilizing hook for parking: The handle shall be turned back to zero gear by gear within a certain distance from the crown block to the pre stop position. Properly brake once or twice while the crown block gradually decelerates. When the hoisted object swings forward, immediately follow the vehicle for one or two times in low gear to make the hoisted object smoothly pre stop at the parking point.

6. Shake stabilization hook: It shows that the lifting object swings back and forth in a large range, while the hook shakes several times in a swing angle of the lifting object at a small angle. The shaking may be caused by the eccentricity of the middle of the lifting object or the different length of the wire rope. When this happens, swing the object in the same direction as the shaking direction of the hook, quickly follow the hook back and quickly push the control handle back to the zero position. In this way, the angle of jitter will be reduced after a round trip with the hook. Generally, the hook can be stabilized two or three times.

That's it Huai'an Crane Leasing Company The six hook stabilizing tips introduced to you are expected to be helpful to all hanging friends. If you want to know more about construction machinery leasing, please enter our official website, and we will provide you with more detailed explanations!
