SmartGroup America produces SG450 and SG650 lifters. The SG Lift is developed by the engineers of the original Smartlift and has been updated for improved functionality, safety and productivity. Electric motors power the hydraulic pistons to lift heavier loads faster. All SG lifts can reach 18 feet 6 inches high, and the load cell is monitored with an LED readout showing when the unit is approaching its load capacity.
