Transport vehicle and installation method for case of mobile power generation system

A transport vehicle for a case of a mobile power generation system, comprising:

• a chassis comprising a main beam, wherein the main beam comprises a first body portion;
• and
• a lifting mechanism assembly, located on the chassis and comprising:
• a turning frame, hinged to the chassis at a hinged position of the chassis, wherein the turning frame comprises a positioning end configured to be connected to the chassis and a free end opposite to the positioning end;
• at least one turning hydraulic cylinder, connected to the turning frame and the chassis, and configured to drive the turning frame to rotate relative to the chassis to change an angle value of a first included angle between a first plane in which a surface of the first body portion facing towards the turning frame is located and a second plane in which a surface of the turning frame facing away from the first body portion is located;
• and
• a connecting frame, configured to be detachably connected to the case, wherein the connecting frame is movably connected to the turning frame in a first direction and a second direction, and the first direction is a direction from the positioning end to the free end, the second direction is perpendicular to the second plane, and the first direction intersects the second direction,
• wherein the main beam further comprises a second body portion, the first body portion is located between the hinged position and the second body portion, and a third plane in which a surface of the second body portion facing towards the turning frame is located is farther away from the connecting frame than the first plane;
• and wherein under a circumstance that the angle value of the first included angle is smallest, a part of the lifting mechanism assembly is located between the first plane and the third plane.
