Swing doors for industrial and heavy-duty lifts with external door hinges

DT 39/1

The door is available as a single-panel version DT 39/1 for use in public areas or on vandal-proof lifts.

DT 39/2, 3, 4

With its sturdy construction (door panels made of 2mm sheet steel and door frames of 4mm sheet steel) and external hinges with integrated height adjustment, the DT 39/X is the ideal solution for heavy-duty industrial lifts. 

The frame and door panel contours as well as the position of the pivot point have been selected to ensure a clear door width at a door opening angle of 90°. The doors can be opened up to 180°, whereas the lift can already be loaded with the entire internal frame clearance when doors are opened at 125° or more.

The modular design of these swing doors makes it easy to replace individual frame parts or the door panels in case of any damage. A symmetrical or asymmetrical door panel layout or the option to have a two, three or four door panel setup opens up a wide variety of design possibilities for individual applications. DT 39/X is available on request even in door sizes that are far beyond standard door sizes.
