The crane brake comprises a base, a drive unit, a left brake arm, a right brake arm, a left friction plate, a right friction plate, a link unit, an elastic unit and a limiter. The drive unit is fixed to the base. The left brake arm and the right brake arm face each other. The bottom of the left brake arm and the bottom of the right brake arm are rotatably connected with the base. The left friction plate and the right friction plate face each other. The left friction plate is mounted on the left brake arm. The right friction plate is mounted on the right brake arm. One end of the link unit is connected to a telescopic rod of the drive unit; other two ends of the link unit are connected with the top ends of the left and right brake arms, respectively; two ends of the elastic unit are connected to the upper middles of the left and right brake arms. The limiter is fixed to one side, opposite to the left friction plate and the right friction plate, of the left brake arm and/or the right brake arm; a gap of preset size is provided between the bottom of the limiter and the base.
