The present invention provides a transportation frame for an oversize container or the like and a method of installing the frame onto the container or the like. The transportation frame includes a top frame body comprising two top corner fittings each provided with a top corner fitting hole, a bottom frame body comprising two bottom corner fittings each provided with a bottom corner fitting hole, and a plurality of posts each having two ends connected to the top frame body and the bottom frame body respectively. The orientations of the two top corner fitting holes and the distance therebetween, and the orientations of the two bottom corner fitting holes and the distance therebetween satisfy the requirements for coupling with corner fittings of neighboring stacked containers. With the invention, non-standard containers may be easily hoisted, stacked and transported. Moreover, the transportation frame can be easily operated and stored while being reusable.
