The invention discloses a lifting tool. The lifting tool comprises lifting hook assemblies. Each lifting hook assembly comprises a yoke plate, a beam and a lifting hook, wherein the lifting hook is arranged on the yoke plate, the yoke plate is arranged on the beam, and the lifting hook rotates by 360 degrees in the beam along the plumb line. A crane with the lifting tool comprises a sliding wheel set, a hanging beam, pin shafts and the lifting tool. The lifting hook assemblies are hung on the hanging beam and arranged on the hanging beam through the pin shafts. The hanging beam is connected with the sliding wheel set. The lifting hook assemblies transversely swing and rotate along the center line of the pin shafts and longitudinally swing and rotate along the axis center lines of the beams. The center lines of the lifting hooks, the axis center lines of the beams and the center lines of the pin shafts form a 90-degree angle in space. According to the lifting tool, hook heads of the lifting hooks rotate flexibly in the three-dimensional space, the safety accidents caused by slanting pulling and slanting hanging of the lifting hooks are avoided, the safety performance of the lifting tool is improved greatly, the service life of the lifting tool is prolonged, and the production efficiency is improved.
