Geared elevator modernization

This solution saves you time, energy and costs. We replace your Direct current (DC) hoist motor to AC while cleaning and reusing your existing machine, including gears, sheaves and bedplates. By simply modernizing the critical components, we’ll improve the reliability and performance of your existing geared traction elevator.
