Below are the methods for stabilizing the hook of a crane truck: 1. Stabilizing front and back swings: When the load swings back and forth, i.e., along the direction of the trolley track, the method to stabilize this swing is to activate the trolley to follow the direction of the load's swing. If the follow-up is timely and appropriate, one follow-up can eliminate the swing. If one follow-up does not completely eliminate the swing, the above method can be repeated until the swing is fully eliminated. 2. Stabilizing left and right swings: When the load swings left and right, i.e., along the direction of the gantry track, the method to stabilize this swing is to activate the gantry to follow the direction of the load's swing. When the load approaches its maximum swing amplitude (the point where the load starts to swing back), stop following. This ensures the load is in a vertical position. The follow-up speed and distance should be determined based on the load's swing position and amplitude when starting the follow-up. Similarly, if one follow-up does not completely eliminate the swing, it can be repeated once. Generally, 1-2 follow-ups are sufficient to stabilize the load if the speed and distance are appropriate. 3. Starting stabilization: Starting stabilization is key to ensuring balanced operation. When the gantry or trolley starts, especially during sudden starts or rapid gear shifts, the vehicle body moves forward a distance S. The load, connected to the vehicle body via flexible steel ropes, lags behind the vehicle body by a distance S due to inertia. This causes the load to deviate from its original stable equilibrium position OG vertical line, resulting in a swing.
