Dual column workstations combine the versatility of full rotation and positioning with heavy-duty lifting power. Its vertical movement is driven by an electric pump-chain design with a carriage riding up and down on linear rails bolted to the dual columns. An articulating arm is capable of full rotation on an axis parallel to the floor. It is rotated manually or electrically along the base, which allows the workstation to interface with other devices in different positions. It is ideal for systems integration. Unidex manipulators are used to lift mating pieces into position.
