The invention provides a pin pulling device and a crane, and belongs to the technical field of offshore hoisting machinery. The pin pulling device comprises a mounting base, a telescopic mechanism, a hinge pin shaft, a guide connecting plate and a guide rail, the telescopic mechanism is located on the mounting face of the mounting base, a telescopic rod of the telescopic mechanism is hinged to the first side edge of the guide connecting plate, the second side edge of the guide connecting plate is hinged to the hinge pin shaft, and the first side edge and the second side edge are the two opposite side edges of the guide connecting plate. The guide rail is located on the installation face, the sliding face of the guide rail is far away from the installation face, the guide connecting plate is located on the sliding face, and the distance from the sliding face to the installation face is gradually increased in the arrangement direction from the first side edge to the second side edge. The coaxiality of the pin shaft and the pin hole is guaranteed, and the pulling and inserting efficiency of the pin shaft is improved.
