The utility model relates to a collapsible track heavy object moves and carries device. Its characteristics are: become with one section upset track set by one section trapped orbit, this trapped orbit is fixed on the base, it connects (3) to be equipped with the C type in the orbital one end of this upset, one end that this C type connects (3) articulates on this base and the other end that this C type connects (3) is connected with the flexible end of linear displacement mechanism, thereby can and shorten the contained angle of adjusting between upset track and the trapped orbit through this flexible extension of holding, be equipped with travelling car (5) on this trapped orbit, install motor or incorporated hand -operated device on this travelling car (5), thereby can drive travelling car (5) moves on trapped orbit or upset track. Through identification on probation, adopt the utility model discloses device back can be through overturning rotatory 90 degrees of track, and it is parallel with the divider direction of height to make upset orbit portion divide, and the occupation of land space of the whole device that significantly reduces can be transported installing the use vehicle.
