AI Technical Summary
Existing folding booms can become disengaged due to bumpy road surfaces during vehicle operation, causing them to swing up or down, resulting in collision damage and affecting normal operation.
Electromagnetic modules are installed between adjacent boom sections. The controller obtains motion signals to control the electromagnetic modules to selectively maintain or release the magnetic attraction between boom sections, preventing the boom sections from swinging up or down when folded or retracted.
It effectively prevents collisions between boom sections, protects equipment safety, extends service life, and ensures that vehicles can smoothly pass through bumpy roads and height-restricted surfaces.
