The disclosure relates to a crane and a method for luffing the boom of a crane, in particular a mobile lattice boom crane, having an upper carriage and a boom articulated to the upper carriage so as to pivot about a horizontal axis. The boom is braced via a bracing frame mounted on the upper carriage and can be luffed up and down by pivoting the bracing frame. The crane comprises a luffing aid device, which can exert a torque acting in addition to the bracing on the boom for luffing the boom in a flat boom position. The luffing aid device comprises an auxiliary arm pivotably mounted on the upper carriage and connected to the upper carriage via a retaining element and to the boom via a variable-length traction element. The traction element exerts a tractive force on the boom in the direction of the auxiliary arm.
