The present invention relates to a push pull apparatus for heavy load transfer, and more par¬ ticularly, to a push pull apparatus and method for heavy load transfer, which generates two forces having the same magnitude, by which a bogie train with a heavy load laded thereon is pushed and pulled on a skid rail, so that the bogie train can be transferred in a pulling or pushing way. A push pull apparatus for heavy load transfer according to the present invention comprises a frame cover 2 having guide rollers 20 provided at front and rear thereof to be movable on a skid rail 110; a plurality of launching cylinders 3 having piston rods 3d fixed at one inner side of the frame cover 2 in the same direction and operated by hydraulic pressure; and clamping devices 4 respectively coupled to the rears of the launching cylinders 3 to fix or release the launching cylinders 3 onto or from the skid rail 110. Accordingly, in a case where the bogie train should be moved in an opposite direction while a load is transferred using a bogie train, contrary to the prior art, it is possible to move the bogie train only using the push pull apparatus without any additional device such as winch, thereby being capable of ensuring convenience and efficiency in work.
