The Model SR-A1™ Rapper, also known as the Hopper Rapper, is our most universally applicable rapper. Delivers 0-25 pounds of impact force at any mounting angle, even upside down. The Model SR-A1™ Rapper comes with a 6" square flange mount or a 2" diameter tapered mount.
The Hopper Rapper uses a heavy duty spring coil and 20 pound hammer design. When compressed, it generates the energy necessary to provide the impact force required. The hammer is fitted with two Teflon rings which eliminates friction to insure a long life with consistent results.
The unit is then sealed inside a steel tube with a shock isolating base/anvil.
The impact of the hammer in the Model SR-A1™ Rapper causes high peak acceleration in the connected surface or shaft. The rapid acceleration of the surface or plate or high voltage frame overcomes the adhesive force that binds many materials to them.
