How is boom whip eliminated in dynamic compactors?

The correct answer is the use of front and rear pendants to eliminate boom whip in dynamic compactors. This technique stabilizes the boom and helps to control its motion during operation. By employing both front and rear pendants, the forces acting on the boom are balanced, which minimizes excessive flexing or whipping, leading to safer and more effective operation.

Using only a single pendant would not provide the same level of stability, as it could allow for increased movement and control issues. Likewise, simply increasing the weight of the load does not address the dynamics of the boom's movement and could lead to other operational challenges. Reducing the angle of the boom might modify its range of motion, but it does not inherently resolve the issue of boom whip created during dynamic activities. Therefore, the combination of front and rear pendants is essential for effective boom stabilization and the elimination of whip effects in dynamic compactors.
