The invention discloses a motor train unit power unit component hoisting supporting device and a hoisting method, and relates to the field of rail transit vehicle converter installation. The hoisting supporting device comprises an insulating bidirectional supporting column, a bracket and a bracket fixing plate; the insulating bidirectional supporting column is cylindrical, a metal column body is arranged inside the insulating bidirectional supporting column, an insulating casting body is arranged outside the insulating bidirectional supporting column, a metal stud is fixedly connected to the head end of the metal column body, a hollow threaded hole is formed inside the tail end of the metal column body, and a nut is fixedly arranged; the support is in a rectangular plate shape, a plurality of kidney-shaped holes are formed in the middle of the support, and the left end and the right end of the support are each provided with a kidney-shaped hole. The support fixing plate comprises a horizontal part and a vertical part which are fixedly connected, the support is connected to the support fixing plate through a bolt hole of the horizontal part, and the vertical part of the support is installed on the power unit frame through two bolts. The hoisting of the power unit component of the motor train unit is completed through a corresponding method. According to the invention, the longitudinal tension of the busbar to the IGBT terminal can be avoided, and the stability of the hoisting structure is ensured; and the hoisting requirements of the converter component of the motor train unit can be better met.
