Designed for ease of use and maintenance, Eberbach’s 6000 Variable-Speed Mid-Range Reciprocal Shaker is ideal for your general purpose shaking needs. This heavy-duty unit operates in a space of 33-1/2" x 20" and is powered by a 1/6 hp GE split phase motor which drives the platform through a mechanical transmission utilizing a variable pitch pulley system incorporating a V-belt drive. Speed control is continuously variable between a range of 60-260 osc/minute (upper and lower speed limits may vary by 5%). At a given setting the speed is constant and unaffected by normal line voltage fluctuations. The horizontal stroke is fixed at 1-1/2", and the unit has a max load carrying capacity of 50 lbs. Double the unit’s shaking capacity with the addition of a tiered platform system. A digital count down timer is available as an option. Supplied without a platform or box carrier.
