The utility model belongs to the technical field of electric hydraulic cranes, and discloses a multifunctional electric hydraulic crane which comprises a movable supporting assembly. The supporting assembly is rotationally connected with a hoisting assembly, and a limiting frame which reciprocates relative to the hoisting assembly is mounted on the supporting assembly; and a plurality of convex teeth are fixedly connected to the concave position of the limiting frame in an annular array, and the limiting frame is used for abutting against the rotated hoisting assembly, so that the hoisting assembly cannot rotate. The lifting hook and a lifted object are driven by the rotating disc to rotate to the angle required by a user, the limiting frame is driven by the electric push rod to move, and the convex teeth on the limiting frame are clamped with the gear, so that the angle between the gear and the rotating shaft is fixed; the device is not easy to deflect accidentally after the angle of the lifted object is adj
