For mounting of larger loads at large height, for example for attachment of rotor blades on wind turbines, a lifting tool (8) is often used, wherein the rotor blade is placed during lifting and mounting of the rotor blade on the rotor hub of the wind turbine. However, sometimes situations arise, wherein displacement of the center of mass between a loaded and unloaded lifting tool (2), will require a displacement of the lifting point of the lifting tool, before the lifting bracket (2) is loosened from the rotor blade, so that the crane's main wire (6) shall be reposition in order to again become vertical. It can, however, be relatively difficult to determine the main wire's orientation, which leads to a lifting bracket (8), comprising an elongated element (14) with a first through-going outlet (16) configured to uptake a part (17) of a first link (19), which is in connection with the main wire (6), and a second through-going outlet (18) configured to uptake a part of a second link on the load (2, 4), which is characterized in that the second through-going outlet (18) comprises a spherical bearing (22), which is configured to uptake the second link, and wherein the elongated element (14) adjacent to the spherical bearing (22) comprises a measuring instrument (26) with a signal transmitter (28) for registering the angle (A) between the lifting 'wire (6) and the vertical direction, wherein the signal transmitter (28) is configured to transmit a signal containing measurements for visualization on an external unit (30) with a screen (31 ) for visualization, placed at the crane operator and/or near the crane supervisor.
