Abstract
This invention incorporates a unique process for alignment of a reciprocable frame between the shafts of the mast of a fork lift. By using a shim having a thickness of about one-eighth inch between the inside surfaces of the shafts and the edges of the frame, guide rollers on the outside of the shafts can be adjusted to hold the frame in alignment. Guide roller adjustment is accomplished by mounting the rollers on eccentrics which are adjusted after the shim is in place. After adjustment the rollers are locked in place. Then after the shim is removed the rollers inherently align the frame between the vertical shafts.
