Abstract
A leaf chain drive assembly (20) designed for use with a platform lift of the type disclosed in U.S. Pat. No. 4,058,228. Leaf chains (72, 120, 208) are used in place of roller chains for transmitting rotational drive between spaced sheaves (50, 60). Each sheave contains a unique projecting lug (52, 54) designed to engage a correspondingly sized connecting link (122) in the associated leaf chain (120) so as to permit drive to be transmitted between the leaf chain and the associated sheave.
