Craneway Doors are essential in heavy industrial environments where overhead cranes are used to transport large or heavy materials from one environment to another or from the interior to the exterior of the building. The nature of an overhead crane necessitates a custom-designed two-part system; the upper and lower door portions. The upper portion allows passage of the crane structure while the bottom allows passage of the load. Several design configurations can be used depending upon constraints imposed by the building and overhead crane characteristics. Any combination of upper and lower door style can be selected.
