In intensive training, the beating brush is experiencing serious stresses. In order to increase the cushioning, to reduce the load on the brush and, accordingly, the risk of injury and the stabilizing suspension on springs was invented.
Thanks to springs, vibration from shock is extinguished and even if you hit the bag is not quite right, the risk of injury is minimal.In addition, the presence of springs can increase the life of both the suspension itself and the bracket (or, to reduce the risk of cracking, if the bag is attached to the ceiling), since the springs absorb most of the impact energy.
