The invention relates to a slideway type combined fork arm of a forklift. The combined fork arm comprises fork arm bodies, fork arm groups, standing sliding blocks, flat sliding blocks, slideways, a fork arm lifting device, a fork arm pushing device, fork hanging blocks, and a control system. The slideway type combined fork arm is used for forking and transporting box type and bag type objects with bottoms without fork insertion space. The lifting device is composed of fork hanging blocks, standing sliding blocks, slideways, and lifting cylinders. The pushing device includes slidways, flat sliding blocks, motors, reels, guide wheels, and stay cords. One fork arm group contains two fork arms; and two fork groups are installed on one forklift. When one article is forked and transported, a wedge opening at the front end of one fork arm is inserted into the little gap of the bottom of the article and then the fork arm is lifted to expand the gap; and the other fork arm is inserted into the expanded gap immediately and then the operation is carried out alternately. After the fork arm front ends are inserted into the gap, the two fork arms rise alternately to lift the article without move, go down, move forward and then rise until the bottom of the article is penetrated. During unloading, the two fork arms lift the article without any move, go down, and retreat above the article placing point until the article is placed on the placing point.
