Duplex mast - DPT / 1085

The duplex upright is a two-stage assembly with full free lift. This upright resembles the standard upright and works in the same way, except a primary, center-mounted cylinder provides full free lift. The primary cylinder also raises the carriage at a 2-to-1 ratio but raises the carriage to the top of the inner rails before the hydraulic fluid is rerouted to the side-mounted secondary cylinders for direct rail lift.
