GLWD FAMILY of Barrier Lift Gate Operators

Commercial and Industrial Applications

The GLWD Family of Barrier Lift Gate Operators utilize our advanced adaptive motor and control system technology that enables significantly higher power density, dramatically better performance and continuous system operation on battery power during loss of AC power.. Each operator is capable of operating at voltages from 115, 208, 230, 460 or 575 VAC single phase, 3 phase multi-voltage transformer.
