Abstract
A heat transfer element basket assembly for a rotary regenerative heat exchanger having a splitter plate or stiffening member mounted between the heat transfer plates at a position intermediate between the inner and outer ends of the basket. The stiffening member includes elongated slots adjacent the top surface which accommodate lifting lugs. Elongated slots and lifting lugs also may be included adjacent the bottom surface of the basket. These lugs slide up and down within the elongated slots to an extended position partially above the surface of the basket when in the lifting mode and to a retracted position fully below the surface when not in use. Since the lugs are retracted when the basket has been placed in the rotor, they will not interfere with the vertically adjacent baskets. This means that the baskets have a low profile and can be tightly packed in the rotor.
