The MBW GPX series of economical vibratory plates are portable, and offer outstanding compaction performance. A patent-pending suspension system that places shock mounts in a predominantly shear mode at the high amplitude front end of the plate and a predominantly compressive mode at the low amplitude trailing end of the plate. This system reduces hand arm vibration and also better isolates all upper mass components, including the engine, from vibrations produced by the machine's exciter. With amplitudes up to .067 inches, centrifugal force up to 2780 lbf and travel speeds to 75 feet per minute these plates are ideal in confined areas of granular soils including sands, bank run, gravels and capable of achieving lift depths of up to 12 inches (31 cm).
