Backpack vibrator model

The new backpack vibrator model from Stone Construction Equipment features a 2.5-hp Honda engine. Made of a lightweight steel frame and extra-thick padding for more operator comfort, the unit weighs 24 pounds. The backpack vibrator is controlled by a patent-pending rotary throttle, which is designed to consistently deliver the proper vibrations per minute for optimum concrete consolidation. It handles all Stone shafts and heads up to 2½ inches. They quickly and easily attach to the backpack power unit with Stone’s patented quick-connect coupler.
