The invention discloses a lifting hook and a crane comprising the same. The lifting hook comprises a hook frame plate, a pulley and a hook body. The hook frame plate is composed of two parallel plate blocks. The pulley is supported in the hook frame plate through a rotation shaft. The hook body is provided with two L-shaped claws which are symmetrically arranged and connected to the two sides of the hook frame plate through a rotation pair. The lower free end face of each claw is arc, each arc end face is longitudinally divided, and a half of each arc end face is removed, so that each free end face comprises a stretching arc end and a concave arc end, and the stretching arc ends and the concave arc ends of the two claws are matched. An upper free end which inclines in the direction away from the outer end face of the hook frame plate is arranged on the joint of each claw and the hook frame plate. The rotation shaft is further provided with a poking block which does not rotate relative to the rotation shaft. When the poking block is engaged with the oblique end face of the upper free end, the lower free ends of the two claws are matched with each other, and when the poking block is disengaged from the oblique end face of the upper free end, the lower free ends of the two claws are separated. By means of the lifting hook, a lifting rope is easy and convenient to install or take out, and the lifting rope can be prevented from dropping.
