The invention discloses a digging arm assembly lifting tool for a backhoe loader. The digging arm assembly lifting tool comprises a lifting support, a limiting shaft, a roller and a clamp, wherein thelifting support comprises a top plate, a left side plate and a right side plate. Front inner ribbed plates are welded at the front ends of the inner sides of the top plate, the left side plate and the right side plate, and ribbed plates are welded at the front ends and the rear ends of the inner sides of the top plate, the left side plate and the right side plate and are used for increasing the stiffness of the top plate, the left side plate and the right side plate. A lifting plate is welded in the middle of the upper part of the top plate, thereby achieving the function of adjusting the lifting center of gravity. A side wall is welded at the junction of the upper end of each side plate and the top plate, and a limiting shaft fixing ring is arranged at the lower end of the side wall andis used for usually placing a limiting shaft. The limiting shaft is a hollow round steel, one end of the limiting shaft is welded with a round hasp, and an external thread is arranged at the other endof the limiting shaft and is used for connecting with a round cover with an internal thread. Relative to other digging arm assembly lifters, the digging arm assembly lifting tool has the advantages that the ribbed plates arranged on each side have good safety, and the equipment has good variability through turning point limiting holes and is suitable for more scenes.
